La Fundación para Investigaciones Biológicas Aplicadas (FIBA) lamenta el fallecimiento del Dr. Ruben H. Vallejos, quien ha sido un destacado científico, fundador y primer director del CEFOBI (Centro de Estudios Fotosintéticos y Bioquímicos) en la Universidad Nacional de Rosario (Santa Fe, Argentina), y formador de recursos humanos en el área de la bioquímica, biología molecular y biotecnología de plantas.
El Dr. Vallejoserecibió de Farmacéutico y Licenciado en Farmacia y Bioquímica en la Universidad Nacional de La Plata, y allí hizo su Tesis Doctoral sobre Propiedades de los sistemas multienzimáticos de transporte de electrones bajo la dirección del Dr. Andrés O.M. Stoppani (1965). Fue becario de CONICET y continuó como miembro de la CIC del CONICET, hasta llegar a la categoría de Inv. Superior en 1993. Se desempeñó como Profesor Titular de Química Biológica desde 1970, en la Facultad de Ciencias Bioquímicas y Farmacéuticas de la Universidad Nacional de Rosario.
En el año 1976 sobre la base del departamento de Bioquímica de la Facultad de Ciencias Bioquímicas y Farmacéuticas, se creó el CEFOBI, Centro de Estudios Fotosintéticos y Bioquímicos (convenio CONICET, la Universidad Nacional de Rosario y la Fundación Miguel Lillo), instituto de investigación básica y aplicada en el área de las ciencias biológicas de organismos fotosintéticos, del cual es su primer director hasta 2006, cuando se jubila.
El Dr.Vallejos fue autor de numerosos trabajos científicos, organizó y participó en también numerosas reuniones científicas, conferencias y cursos. Se destaca su participación en el desarrollo de la biotecnología vegetal y la transformación de plantas, registrando una de las primeras patentes nacionales en la temática.
Sin dudas, uno de los más destacados aportes del Dr. Vallejos fue la formación de recursos humanos, que continúan con su legado.

To seal or not to seal. Characterization of root sealing regulatory mechanisms in plant colonised by microbes
Plant roots are responsible for nutrient and water uptake from the “outside” environment; the soil. This process is controlled by a specialized cell layer in the root, the endodermis. To keep the right concentration of nutrients in the plant, avoiding its leakage, this cell layer has evolved mechanisms of sealing, the blockage of the space between contiguous cells. One missing aspect in this sealing mechanism, critical for the organism survival, is the resident microbiota that is metabolically active and might disturb the cell layer sealing with consequences for nutrient and water balance. With this proposed project we will explore a new technological concept around the use of exogenous small molecules that mimic plant regulatory components to control the root sealing mechanisms directly or through their interactions with the resident root microbiome. It represents an invaluable tool to gain new insight into the regulation of new mineral nutrient homeostatic mechanisms controlled by the root microbiota. Questions we will address include: What regulatory molecules coordinate the crosstalk between the root sealing and the microbiota? How do different regulatory elements control mineral nutrient accumulation under ecological relevant conditions?
The project will be supervised by a team of supervisors that includes Dr Claudio Screpanti from Syngenta and Dr Gabriel Castrillo and Dr Almudena Ortiz-Urquiza from the University of Nottingham. You will join our Plant-Microbe interactions and nutrition group (www.gabrielcastrillo.com) at Sutton Bonington campus, Plant Sciences building at the University of Nottingham.

Plant Physiology Article of the Week: Fungal Dual-Domain LysM Effectors Undergo Chitin-Induced Intermolecular, and Not Intramolecular, Dimerization
The spotlight is on Hui Tian, Gabriel L. Fiorin, Anja Kombrink, Jeroen R. Mesters, and Bart P.H.J. Thomma. They show that fungal LysM effectors composed of two LysM domains bind chitin via intermolecular LysM dimerization, leading to polymers that may precipitate to eliminate chitin from infection sites to prevent the activation of host immune receptors.
The Plant Cell Article of the Week: Breeding Crops for Drought-Affected Environments and Improved Climate Resilience
The spotlight is on Mark Cooper and Carlos D. Messina. They review approaches that have been used to breed crops with improved levels of drought resistance and conclude that action now to develop platforms to facilitate the integration of scientific knowledge from genes to ecosystems, and their application within breeding programs will create new opportunities to hasten the transition towards more socially and environmentally responsible crop breeding strategies that are responsive to the pressures of climate change.

| Taina Tyystjärvi (University of Turku, Finland) High CO2 enhances photosynthetic activity and growth of cyanobacteria. How cells sense the amount of inorganic carbon and balance cellular functions accordingly remains poorly understood. Our recent results reveal a novel signaling cascade that connects growth to the amount of inorganic carbon in the cyanobacterium Synechocystis sp. PCC 6803. Transfer of the Synechocystis control strain (CS) cells from ambient air to 3% CO2 was found to activate the expression of photosynthesis and growth related genes by reducing the formation of RNA polymerase (RNAP) holoenzymes containing the growth-restricting SigC sigma factor. Acclimation of Synechocystis cells to high CO2 is prevented if the small ω subunit of the RNA polymerase (RNAP) core is deleted. Without the ω subunit, the formation of the RNAP-SigC holoenzyme was enhanced in high CO2, and transcriptome analysis showed decreased expression of numerous photosynthetic and cell wall genes in the ω-less ΔrpoZ cells compared to the CS cells in high CO2. Due to these transcriptional changes, high-CO2-induced enhancement of photosynthesis was largely missing in ΔrpoZ cells and inefficient synthesis of the peptidoglycan layer of the cell wall induced lysis of dividing ΔrpoZ cells in high CO2. Spontaneous secondary mutations in the ssr1600 gene rescued the high-CO2-sensitive phenotype of the ΔrpoZ strain. Our results show that the Ssr1600 protein functions as an anti-SigC antagonist regulating the formation of the RNAP-SigC holoenzyme. The amount of the Ssr1600 protein responds to CO2 concentration, regulating the formation of the growth restricting RNAP-SigC holoenzyme according to available inorganic carbon. We suggest a partner switch mode of action for the Ssr1600 protein. Formation of the anti-SigC antagonist Ssr1600/anti-SigC complex releases the SigC sigma factor from the SigC/anti-SigC complex and growth restricting RNAP-SigC holoenzymes are formed. |

Plant Direct Article of the Week: Pisum sativum Has No Competitive Responses to Neighbors: A Case Study in (Non)Reproducible Plant Biology The spotlight is on Mariah L. Mobley, Audrey S. Kruse and Gordon G. McNickle. They find from reviewing published literature, that the six cultivars of pea which have been studied likely have no responses to a neighbor-volume manipulation at any pot volume ranging from 50 to 6,300 ml (varying mostly by depth). They conclude that this was simple statistical sampling error which is expected when science and frequentist statistics are operating as intended and suggest that it might be valuable to attempt to replicate some of the finer scale results reported for pea, to further explore how increases in horizontal space to increase volume might affect pea, but for coarser-scale questions it might be worth expanding the diversity of species and genotypes for which we have data about root responses to the neighbor-volume manipulation. |
