Analysis of gene expression and physiological responses in three Mexican maize landraces under drought stress and recovery irrigation.

ABSTRACT:

Background

Drought is one of the major constraints for plant productivity worldwide. Different mechanisms of drought-tolerance have been reported for several plant species including maize. However, the differences in global gene expression between drought-tolerant and susceptible genotypes and their relationship to physiological adaptations to drought are largely unknown. The study of the differences in global gene expression between tolerant and susceptible genotypes could provide important information to design more efficient breeding programs to produce maize varieties better adapted to water limiting conditions.

Methodology/principal findings

Changes in physiological responses and gene expression patterns were studied under drought stress and recovery in three Mexican ma
