Conteúdo: | Dehydration during drought triggers molecular events that result in physiological, morphological and developmental responses in plants. Induced genes during cell dehydration are normally related to mechanisms of cell dehydration tolerance. Protection of cell structures, changes in cell osmotic potential, expression regulation of the other genes, metabolization of produced compounds by the stress are among the gene products induced during drought. The objective of this study was isolation and study on genes expression in soybean roots during dehydration. cDNA libraries were prepared with mRNA obtained from roots submitted to dehydration conditions. About 3200 expressed genes have been sequenced and stored in vitro and in silico. Comparison of these sequences with the sequences deposited in the GenBank allowed identification of probable gene functions and categorization of genes for use as molecular markers in plant breeding programs or as key genes in metabolic pathways that potentially could improve drought tolerance. The following probable gene-related functions were: metabolism, cellular protection, gene expression regulation, cellular signaling, transport, cellular structure, cell division, proteins related to stress response and unknown proteins. The access to this data can be done though the site www.cnpso.embrapa.br/bioinformatica. Unique sequences identified in the data bank are been selected for microarray analysis at Universidade Estadual de São Paulo-UNESP.
