Comparative transcriptomic and physiological analyses of contrasting hybrid cultivars ND476 and ZX978 identify important differentially expressed genes and pathways regulating drought stress tolerance in maize

Background Drought is the major abiotic stress factor that negatively influences growth and yield in cereal grain crops such as maize ( Zea mays L.). A multitude of genes and pathways tightly modulate plant growth, development and responses to environmental stresses including drought. Therefore, cro...
