Identification of soybean genotypes with high stability for the Brazilian macro-region 402 via biplot analysis

Biplot analysis has often been used to recommend genotypes from different crops in the presence of the genotype x environment interaction (GxE). The objective of this study was to verify the association between the AMMI and GGE biplot methods and to select soybean genotypes that simultaneously meet high grain yield and stability to the environments belonging to the ..

Soybean physiology and gene expression during drought

    R. Stolf-Moreira, M.E. Medri, N. Neumaier, N.G. Lemos, J.A. Pimenta, S. Tobita, R.L. Brogin, F.C. Marcelino-Guimarães, M.C.N. Oliveira, J.R.B. Farias, R.V. Abdelnoor and A.L. Nepomuceno

Soybean genotypes MG/BR46 (Conquista) and BR16, drought-tolerant and -sensitive, respectively, were compared in terms of morphophysiological and gene-expression responses to water stress during two stages of development. Gene-expression analysis showed differential responses in Gmdreb1a and Gmpip1b mRNA expression within 30 days of water-deficit initiation in MG/BR4.. Read More»

Cloning and quantitative expression analysis of drought-induced genes in soybean

    R. Stolf-Moreira, M.E. Medri, N. Neumaier, N.G. Lemos, R.L. Brogin, F.C. Marcelino, M.C.N. de Oliveira, J.R.B. Farias, R.V. Abdelnoor and A.L. Nepomuceno

We determined the expression levels of DREB transcription factor (Gmdreb1) and of the genes Gmgols, Gmpip1b, Gmereb, and Gmdefensin in drought-tolerant (MG/BR46-Conquista) and drought-sensitive (BR16) genotypes of soybean, during drought. The trial was carried out in a controlled-environment chamber, set up to provide drought conditions. Sequences of Arabidopsis tha.. Read More»
