Farewell and Adiós, Santiago!

Today, we had to say good bye to our postdoc Santiago Alejandro. Santiago joined us in 2017 to work on manganese efficiency and metal transport in sugar beet. His work yielded intriguing new insights in the functioning of this crop, with a comprehensive paper    just published a couple of days ago (see below) and more to follow. His authoritative review article    on manganese in plants has evolved to one of the 1% most highly cited articles in plant science. More recently, he has been concerned with processes that determine cadmium accumulation in cereal grains, an issue of great importance for food safety. Santiago has been a formative member of our team, and we will miss him very much. From now, as research scientist in the R&D department of a leading fertilizer manufacturer, he will contribute his great knowledge on nutrients to the development of novel cropping practices. Santiago, we wish you all the very best for the future and a happy family life in Münster!

Sugar beet isn’t Arabidopsis with a tap root - study reveals high diversity in metal handling by dicot plants

Manganese (Mn), iron (Fe), and zinc (Zn) are essential for diverse processes in plants, but their availability from soil is often limiting or excessive. Transport proteins in cellular membranes confer the efficient usage or detoxification of these metals. Knowledge about these processes may be harnessed to improve crops. An important family of metal transporters are the CATION DIFFUSION FACILITATORs (CDFs), called METAL TOLERANCE PROTEINs (MTPs) in plants. Roles of these transporters have been inferred mainly from work on model species, like Arabidopsis thaliana. It is unclear to what extent these findings can be generalized. In a new study, we show that MTPs in sugar beet often deviate from their Arabidopsis counterparts in terms of transported metals, subcellular localization, as well as regulation upon exposure to Fe, Mn, and Zn deficiencies and Mn and Zn toxicities. Also, the ion composition of sugar beet responds differently to metal nutrient imbalances than that of Arabidopsis. These results suggest that metal homeostasis and the employment of the MTP toolbox is highly diverse amongst different plant species, which questions the general applicability of models derived from Arabidopsis and calls for functional studies of these processes on crop plants. The article is published in Plant, Cell & Environment and can be accessed here.

Improving iron nutrition of broccoli

Broccoli is a vegetable of very high nutritional value. However, iron deficiency can cause reduced growth and yield. A study led by Ahmad Kabir at the University of Georgia with contributions from our lab now shows that a nitric oxide donor is able to improve iron acquisition and iron status of this plant. This finding may lead to strategies to improve iron nutrition of broccoli. The article is published in Plant Physiology and Biochemistry and can be accessed here   .

Contribution to perspective article on agriculture and food security under a changing climate

The anthropogenic rise in CO2 provokes massive disruptions in the global climate that will have a tremendous impact on agriculture and food security. In a perspective article led by Ralf Seppelt (UFZ Halle-Leipzig) with contributions of Stefan Klotz, Martin Volk (both UFZ) and Edgar Peiter, the available evidence on how the global food system might look given a global temperature increase by 3° is reviewed. We show that a moderate gain in the area suitable for agriculture is confronted with substantial yield losses through strains on crop physiology, multitrophic interactions, and more frequent extreme events. Self-amplifying feedbacks are unresolved and might lead to further losses. In light of these uncertainties, we see that complexity is underestimated and more systemic research is needed. Efficiency gains in agriculture, albeit indispensable, will not be enough to achieve food security under severe climate change. The article is published in iScience and can be accessed here   .

How lupins detoxify manganese

White Lupins have the ability to mobilize the mineral nutrient phosphate (P) with outstanding efficiency by releasing organic compounds into the soil. This P mobilization also leads to a mobilization of manganese (Mn), which is taken up and accumulates to concentrations that would be highly toxic to most plants. The molecular basis of the Mn detoxification mechanism in White Lupin has been unknown until now. In a collaborative study, Uwe Ludewig and his PhD student Philipp Olt at Hohenheim University, jointly with our postdoc Santiago Alejandro and his Master students Edith Ramos and Johann Fermum have identified and characterized a transport protein that moves Mn into vacuoles of White Lupin, where it is safely stored. This transporter provides a mechanistic explanation for the high Mn accumulation and Mn tolerance in this species. The article is published in Physiologia Plantarum and can be accessed here   .

Regulation of manganese uptake by calcium signalling

Manganese is indispensable for photosynthesis and other processes in plants, like cell wall synthesis (see news of 22 Aug 2022). On soils with low manganese availability, crop growth and yield can be severely reduced. However, it has remained largely unknown how fluctuations in manganese supply are sensed and signalled and how the activity of manganese transporters is regulated. A study led by the groups of Cun Wang (Northwest A&F University, China) and Jörg Kudla (University of Münster) revealed that novel multicellular calcium oscillations are triggered by manganese depletion. These calcium signals are believed to activate a set of protein kinases that again regulate the principal manganese uptake transporter, NRAMP1. Our postdoc Stefanie Höller contributed photosynthesis analyses to this exciting work, that delineates a mechanism of calcium-regulated manganese uptake by plants, which may be a key to increase manganese uptake efficiency of crops. The article is published in the Proceedings of the National Academy of Sciences of the USA (PNAS) and can be accessed here.    A press release by the University of Münster can be found here   .

Regulator of fungal cell wall synthesis revealed

The composition of the fungal cell wall is a crucial factor for virulence of pathogens. A study led by the Institute’s Phytopathology group of Holger Deising has identified the RHO4 protein of the devastating maize anthracnose fungus as regulator of cell wall synthesis, crucial for hyphal growth and infection of its host plant. Kathrin Thor, a former postdoc of our lab, has contributed imaging analyses that show a reduced abundance of the cell wall component beta-1,3-glucan and a compensation by higher chitin abundance in the absence of the RHO4 protein. The article is published in the Journal of Fungi and can be accessed here.

Elucidation of calcium signals in barley

Plants are continuously exposed to changing environmental conditions and biotic attacks that affect growth. In crops, inability to respond appropriately to stress has detrimental effects on agricultural production and yield. Calcium plays a central role in rendering plants resilient to unfavourable conditions. Upon perception of the stress, transient or repetitive rises in free cytosolic calcium trigger mechanisms of defence or adaptation. However, research on such calcium signals has mostly been pursued in the model plant Arabidopsis, while in crop species these events are little investigated. In a collaboration with the labs of Ute Vothknecht (University of Bonn) and Karl-Heinz Kogel (University of Gießen), we therefore introduced a calcium reporter gene in the crop species barley, which enabled us detect calcium signals upon biotic and abiotic stresses and compare those to Arabidopsis. Beside common patterns, notable differences were identified that may relate to different stress responses of both species. The newly generated transgenic barley reporter lines present a valuable tool to further analyse and improve mechanisms of calcium signalling and stress reponse in this crop. The article is published in BMC Plant Biology and can be accessed here.

BICAT3 Golgi Paper

BICAT3 Golgi Paper

22 August 2022
Mechanism of manganese supply for cell wall synthesis revealed

Manganese is essential for life on earth. The element catalyses photosynthetic water splitting in the chloroplast, the process that drives CO2 fixation and that produces the atmosphere’s oxyen. Manganese is also required by glycosyl transferases, enzymes that synthesise the plant cell wall components pectin and hemicellulose and hence determine plant growth. These biosynthetic reactions take place in the cell’s Golgi apparatus, but it is not well understood how manganese enters this compartment. We have identified a transport protein, BIVALENT CATION TRANSPORTER 3 (BICAT3) that supplies the Golgi apparatus with manganese and that determines the distribution of manganese between chloroplast and Golgi under manganese-limiting conditions, as they occur frequently in the field. The BICAT3 protein may hence prove as a yield limiting bottleneck for plant performance at low manganese availability and may be a target for crop improvement. The article is published in Plant Physiology and can be accessed here.    It has been covered in a News & Views article by Stefanie Wege that can be accessed here   . A press release by the University can be found here.

DNA cleavage by enediyne polymer

DNA cleavage by enediyne polymer

19 May 2022
Polymers that cleave DNA

Enediynes are structures of promising antitumor antibiotics that become active upon a Bergman cyclization reaction, which creates a reactive radical. This radical can cause DNA strand breaks, inducing programmed cell death. The lab of Wolfgang Binder (MLU Institute of Chemistry) has now achieved to embed enediynes in the main chain of a polymer. Their DNA cleavage activity can be modified by chain length. These novel polymers can be the basis to design selective DNA-cleaving drugs. Our lab contributed to the DNA cleavage assays of this exciting work, which was led by Yue Cai. The paper is published in Polymer Chemistry and can be accessed here   .

Large study on phosphorus fertilization recommendations in Europe

Phosphorus (P) is a limited resource, and excessive P fertilization can lead to environmental problems. P fertilization recommendations aim to reach or maintain an optimum level of plant-available P in the soil. A comparative analysis led by Kristin Steinfurth and Uwe Buczko at the University of Rostock revealed that thresholds of P recommendations vary by a factor of up to five between European countries. Furthermore, an analysis of European long-term P fertilization experiments showed that those P recommendation thresholds are often much higher than necessary for optimum yield. This calls for a reconsideration P fertilization recommendations in some countries for a more sustainable and environmentally friendly P fertilization. We contributed data sets from our long-term field experiment, that has been running since 1949, to this large-scale analysis. The paper, which is published in Agriculture, Exosystems & Environment, is available online and can be accessed here   .

Paper on metal storage in seeds

Iron and zinc deficiencies are widespread nutritional disorders in humans, affecting more than half of the world’s population. Moreover, improved micronutrient accumulation in seeds can contribute to seedling vigour, abiotic and biotic stress resistance, and enhanced crop yields. Thus, understanding the mechanisms of micronutrient allocation in the developing seed is of great importance. Based on the involvement of the vacuolar transport protein MTP8 in manganese and iron homeostasis in developing and germinating seeds, we hypothesized that its overexpression can confer tolerance to high Mn concentrations during imbibition and bring about an increase in metal concentration in the seed. The latter would render this transporter a promising target for genetic biofortification. Besides determining metal concentrations, we employed high-resolution synchrotron micro X-ray fluorescence (µXRF) tomography to investigate the impact of MTP8 on metal distribution in seeds. The results indicate that, albeit overexpression of MTP8 entails increased tolerance to high Mn levels during seed imbibition, it does not alter Mn and Fe accumulation and allocation.

Bringing together biofortification and cadmium reduction

Genetic biofortification of cereals is an effective means to fight iron and zinc malnutrition in humans (“hidden hunger”). Conversely, cadmium (Cd) is a highly toxic heavy metal that accumulates in grains. Unfortunately, most approaches to reduce Cd in food also have a negative impact on iron, zinc, and manganese. In a vision paper published in New Phytologist, Sakthivel Kailasam of Michigan State University and Edgar Peiter have drafted a potential way out of this dilemma. They propose a directed evolution of transport proteins towards higher selectivity against Cd by employing new genome editing techniques. Click here    to access the article.

Open Letter: The importance of Plant Science to solve the trilemma of land use

In its recent assessment “Rethinking Land in the Anthropocene: from Separation to Integration”   , the German Advisory Council on Global Change (WBGU) has proposed a comprehensive set of solutions to solve the “trilemma of land use”, i.e. reaching the targets of climate-change mitigation, avert the dramatic loss of biodiversity, and make the global food system sustainable. Unfortunately, plant science, including novel methods of crop improvement, is not viewed as part of the solution in this assessment. In an open letter to the federal ministers of the environment (Svenja Schulze), and education and research (Anja Karliczek), a number of plant science institutions and societies, including the German Society of Plant Nutrition   , address this critical shortcoming. They stress the importance of plant science and novel plant breeding approaches in the development of a sustainable agriculture, and they offer to contribute their expertise in plant and crop science.

Review on calcium and manganese in organelles

Calcium and manganese are essential elements for plants and have physicochemical similarities. They are assigned specific functions within cellular compartments, but share many transport mechanisms across cellular membranes. Despite the points of interaction, those elements are usually investigated separately. Our latest review, to which a number of lab members contributed, takes calcium and manganese out of this isolation. It highlights our current mechanistic understanding, and points to open questions, of their functions, their transport, and their interplay in all organelles of the plant cell. Mechanisms in animals and yeast are taken into account where they may provide a blueprint for processes in plants. The article is published in Plant Physiology and can be accessed here.

Paper on a new player in systemic calcium signalling

Plants respond to wounding and insect attack with a rise in their internal calcium concentration. These „calcium signals“ propagate throughout the plant and inform yet intact plant parts of the stress, so that the entire plant can launch defense responses. It is not well understood how those calcium signals are produced. The protein Annexin1 has been known to exhibit calcium channel activity. A new study, led by Axel Mithöfer at the MPI for Chemical Ecology in Jena, with calcium imaging experiments from our lab, shows that Annexin1 is an important player in the plant’s defense responses. Plant devoid of Annexin1 were defective in the generation of systemic calcium signals, had a dimished hormone response, and did not fend off attacking insects. The article is published in New Phytologist and can be accessed here   .

Review on manganese in plants

In  plants,  manganese is of extraordinary importance for photosynthesis,  and also  crucial for other important biochemical reactions, including  oxidative  stress defense. All those reactions take place in specific  cellular  compartments and different parts of the plant. Many transport  proteins,  belonging to diverse proteins families, have been identified  in a  number of plant species to translocate manganese from soil to its   targets. In this review, we provide an extensive overview of all aspects   related with the acquisition and distribution of manganese in plants,   as well as a compilation of the roles of manganese in plants described   so far. We particularly focus on the allocation of manganese on  cellular  and subcellular level. This topic is very timely because the  picture of  plant manganese transport is still rather sketchy and  requires an  inventory of what we know and which steps are still  unresolved. This  compilation of our current knowledge on manganese  transport will be a  very useful tool for scientists and researchers in  the field of plant  nutrition, as well as in other disciplines. The  review is published in  Frontiers in Plant Science and can be accessed here   .

Review on calcium transport in fungi

Calcium is a universal signalling element in all organisms, including fungi. It is essential for development as well as for the initiation of responses to environmental cues. The maintenance of calcium homeostasis and the generation of calcium signals relies on a set of calcium transport proteins: channels, transporters, and pumps. The physiological roles of these proteins have been mainly investigated in some model species, such as baker's yeast, and are believed to be largely similar in all fungi. This assumption is questioned in a new review article, in which a comparative survey of mutant phenotypes of known calcium transport proteins in a wide range of fungi was undertaken. This approach revealed that the involvement of some calcium transport proteins in growth and stress resistance differs widely between fungal species, while the roles of others are more conserved. This calls for a cautious use of the “seen one, seen them all” principle and for mechanistic studies in non-model species. Our survey demonstrates that components of the calcium signalling toolbox may be employed differently in different, but related, organisms and that results may not always be extrapolated from one fungal species to another. The review is based on the dissertation of Mario Lange, a former PhD student in our lab. It is published in Frontiers in Microbiology and can be accessed here   .
