Water and mineral stress effects on cambial activities and wood formation in eucalyptus grandis: identification of key properties for genotype*environment interaction studies under global change


The project aims to study the impact of K substitution by Na on the Eucalyptus response to water stress throughout the plant growth, up to 6 years. Field experiments are already underway at the Itatinga Experimental Station of ESALQ/USP as part of a joint projects between ESALQ and CIRAD (Projeto Tematico FAPESP 2010/16623-9, Projeto Regular 02/11827-9, 05/60312-0), where an innovative trial of water exclusion was assembled. Our goal is to introduce a wood survey approach by anatomical, cambial activity studies including girth growth monitoring, to the ecophysiological studies that are being conducted in the current projects, and to the functional genomics approach of transcriptomics and proteomics of Max Feffer Plant Genetics Laboratorio from Genetic Department of ESALQ/USP, using the same trees. We aim to identify during the wood formation the key properties that might be involved in the regulation of water use efficiency, as well as the effects upon Na+ substitution by K+ in Eucalyptus. The improvement in the understanding of the wood formation combined with hydraulic capacities of Eucalyptus in this context will be beneficial for selection of adapted genotypes to water stress and environments with limited fertility. The project is part of a joint research program established between the Departments of Genetics and Forest Sciences of ESALQ/USP and Cirad (France). Two scientists from Cirad, Dr. Gilles Chaix and MS Bénédicte Favreau, are already working at ESALQ and will lead this project together with a group of Master and PhD students and post-docs of the wood anatomy and wood identification Laboratory of ESALQ-Usp. We also have: -the contribution of a bilateral project Agropolis Foundation and CAPES coordinated by Dr. Gilles Chaix and Prof Mario Tomazello "Impact of water constraint in relation to the mineral element intake on Eucalyptus wood properties and xylem genome expression" (editas 57/2012), of CNPq (Edital MCT/CNPq 014/2012) project "Mudanças climáticas globais: indução do estresse hídrico por exclusão de chuva e efeito no crescimento e formação e qualidade do lenho de árvores de E. grandis com fertilização potássica e sódica" .-the participation, as associate researches, of Dr. Hervé Cochard, Director of Research from INRA-Clermont-Ferrand; Msc Charlène Arnaud, Sophie Nourissier from CIRAD-Montpellier; Drs. Jean-Paul Laclau, Jean Pierre Bouillet, Yann Nouvellon, Msc Bénédicte Favreau ­ CIRAD-Brasil, Dr. Jean Michel Roger - IRSTEA France; Dr. Fernanda Trisltz Perassolo Guedes, Msc Mariana Pires Franco, Dr. Matheus Peres Chagas, Samara Dilio Franzol from ESALQ/USP and Dr. Carlos Alberto Labate from the Max Feffer Laboratory of Plant Genetics of the Department of Genetics.
