Authors: Deyvid Novaes Marques, S�¡vio Pinho dos Reis, Cl�¡udia Regina Batista de Souza
The TCTP (Translationally controlled tumor protein) is a highly conserved protein family found in eukaryotic organisms, which has been associated to the performance of several functions at the cellular level, as those related to growth, development, and responses against environmental stresses. However, studies on TCTP from pl.. Read More»

Iron excess in rice: from phenotypic changes to functional genomics of WRKY transcription factors
Authors: V.E. Viana, N. Marini, T. Finatto, I. Ezquer, C. Busanello, R.S. dos Santos, C. Pegoraro, L. Colombo and A. Costa de Oliveira
Iron (Fe) is an essential microelement for all living organisms playing important roles in several metabolic reactions. Rice (Oryza sativa L.) is commonly cultivated in paddy fields, where Fe goes through a reduction reaction from Fe3+ to Fe2+. Since Fe2+ is more soluble, it can reach toxic levels inside plant cells, constitut.. Read More»

Performance of grain sorghum hybrids under drought stress using GGE biplot analyses
Authors: P.S.C. Batista, C.B. Menezes, A.J. Carvalho, A.F. Portugal, E.A. Bastos, M.J. Cardoso, C.V. Santos and M.P.M. Julio Centro de
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»

Genotypic variation and relationships among nitrogen-use efficiency and agronomic traits in tropical maize inbred lines
Authors: M.C. Rodrigues, W.M. Rezende, M.E.J. Silva, S.V. Faria, L.T. Zuffo, J.C.C. Galv�£o and R.O. DeLima
Improvement in nitrogen-use efficiency (NUE) on maize is among the best strategies to mitigate the problems of poor soil fertility in tropical conditions. The objectives of this study were: i) to quantify the genetic variability for NUE-components and agronomic traits in a set of tropical maize inbred lines; ii) to study the g.. Read More»

Selection of candidate reference genes and validation for real-time PCR studies in rice plants exposed to low temperatures
Authors: P.A. Auler, L.C. Benitez, M.N. do Amaral, I.L. Vighi, G.S. Rodrigues, L.C. da Maia and E.J.B. Braga
Rice is a cereal that presents a great ability to adapt to different soil and climate conditions. However, as it is a tropical crop with C3 metabolism, it performs better in warm temperatures with high solar radiation. Tolerance to stress caused by low temperatures is a highly complex process that involves various metabolic pa.. 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»

Characterization of OsPM19L1 encoding an AWPM-19-like family protein that is dramatically induced by osmotic stress in rice
Authors: H. Chen, H. Lan, P. Huang, Y. Zhang, X. Yuan, X. Huang, J. Huang and H. Zhang
The plant-specific AWPM-19-domain proteins play important roles in plant development and stress responses. In the current study, OsPM19L1 encoding Oryza sativa AWPM-19-like protein 1 was isolated from rice. Tissue-specific gene expression analysis revealed that OsPM19L1 was highly expressed in the leaf sheath of rice. Interest.. Read More»

Genomic identification of group A bZIP transcription factors and their responses to abiotic stress in carrot
Authors: F. Que, G.L. Wang, Y. Huang, Z.S. Xu, F. Wang and A.S. Xiong
The basic-region/leucine-zipper (bZIP) family is one of the major transcription factor (TF) families associated with responses to abiotic stresses. Many members of group A in this family have been extensively examined and are reported to perform significant functions in ABA signaling as well as in responses to abiotic stresses. In this study, 10 bZIP fact.. Read More»
