Breeding for water-deficit tolerance is fundamental to guarantee the sustainability of upland rice production, mainly due to the possibility of an increased frequency of drought episodes due to climate change. This work aimed to identify single nucleotide polymorphism (SNP) markers, derived from RNA sequencing (RNA-Seq), genom.. Read More»

The objective of this study was to estimate the adaptability and stability of grain sorghum hybrids grown under post-flowering water stress and non-stress conditions. The trials were carried out in Nova Porteirinha-MG during the season of 2014 and 2015, and in Teresina-PI in the 2014 season. Twenty-nine-grain sorghum hybrids w.. Read More»

Gas exchanges and water use efficiency in the selection of tomato geno-types tolerant to water stress.
Authors: M.E.A. Borba, G.M. Maciel, E.F. Fraga Junior, C.S. Machado Junior,G.R. Marquez, I.G. Silva and R.S. Almeida
Water stress can affect the yield in tomato crops and, despite this, there are few types of research aiming to select tomato genotypes resistant to the water stress using physiological parameters. This experiment aimed to study the variables that are related to the gas exchanges and the efficiency in water use, in the selectio.. Read More»

Evaluation of grain yield in sorghum hybrids under water stress
Authors: C.B. Menezes, D.C. Saldanha, C.V. Santos, L.C. Andrade, M.P. Mingote J�ºlio, A.F. Portugal and F.D. Tardin
Sorghum grain yield can be significantly affected by climatic changes, especially drought and high temperature. The purpose of this study was to evaluate hybrids of grain sorghum grown under normal irrigation conditions or water stress in order to select those likely to be more tolerant of drought. Forty-nine hybrids were grow.. Read More»

Strategy for selection of soybean genotypes tolerant to drought during germination
Authors: S.A.G. Dantas, F.C.S. Silva, L.J. Silva and F.L. Silva
Water deficit is the main reason for instability in the context of soybean culture. The development of strategies for the selection of more tolerant genotypes is necessary. These strategies include the use of polyethylene glycol 6000 solutions (PEG-6000) for conducting the germination test under conditions of water restriction.. Read More»

Selection of cowpea progenies with enhanced drought-tolerance traits using principal component analysis
Authors: C.C. Sousa,K.J. Damasceno-Silva, E.A. Bastos,M.M. Rocha
Vigna unguiculata (L.) Walp (cowpea) is a food crop with high nutritional value that is cultivated throughout tropical and subtropical regions of the world. The main constraint on high productivity of cowpea is water deficit, caused by the long periods of drought that occur in these regions. The aim of the present study was to.. Read More»

Bulked segregant analysis for relative water content to detect quantitative trait loci in wheat under drought stress
Authors: M.R. Naroui Rad M. Abdul Kadir M.Y. Rafii H.Z.E. Jaafar M.R. Naghavi
This study was carried out to evaluate the genetic effect of quantitative trait loci (QTLs) conferring drought tolerance in wheat. A population of 120 F2 individuals from the cross between the drought-tolerant S-78-11 and drought-sensitive Tajan cultivars were analyzed for their segregation under drought stress conditions. The relative water content under dr.. Read More»

Cotton is one of the most important natural fiber crops in the world. Its growth and yield is greatly limited by drought. A quantitative trait locus (QTL) analysis was therefore conducted to investigate the genetic basis of drought tolerance in cotton (Gossypium spp) using 188 F2:3 lines developed from an inter-specific cross between a wild cotton species..

Effect of overexpression of citrus 9-cis-epoxycarotenoid dioxygenase 3 (CsNCED3) on the physiological response to drought stress in transgenic tobacco
Authors: A.M. Pedrosa, L.C. Cidade, C.P.S. Martins, A.F. Macedo, D.M. Neves, F.P. Gomes, E.I.S. Floh, M.G.C. Costa
9-cis-epoxycarotenoid dioxygenase (NCED) encodes a key enzyme in abscisic acid (ABA) biosynthesis. Little is known regarding the regulation of stress response by NCEDs at physiological levels. In the present study, we generated transgenic tobacco overexpressing an NCED3 ortholog from citrus (CsNCED3) and investigated its relev.. Read More»

Abscisic acid-responsive element binding protein (AREB1) is a basic domain/leucine zipper transcription factor that binds to the abscisic acid (ABA)-responsive element motif in the promoter region of ABA-inducible genes. Because AREB1 is not sufficient to direct the expression of downstream genes under non-stress conditions, a.. Read More»
