A major limitation is due to dependence on a number of physiological traits and each under multigenic control, which arises complexity of tolerance to abiotic stresses. Complexity in stress tolerance traits causes marginal success...

NAC (NAM, ATAF1-2, and CUC2) proteins constitute one of the largest families of plant-specific transcription factors and have been shown to be involved in diverse plant processes including plant growth, development, and stress-tolerance. In this study, a stress-responsive NAC gene, EcNAC1, was isolated from the subtracted stress cDNA library generated from a drought adapted crop, finger millet,...

Phosphate (Pi)-deficient soils are a major limitant factor for crop production in many regions of the world. Despite that plants have innovated several developmental and biochemical strategies to deal with this stress, there are still massive extensions of land which combine several abiotic stresses, including phosphate starvation, that limit their use for plant growth and food production. In s...

Plants frequently encounter a combination of abiotic stresses in their natural habitats. Abiotic stresses, including drought, salt, cold, heat, and heavy metal etc., modulate phytohormone metabolism and enhance expression level of transcription factors which activate stress responsive genes. During plant stress response, reactive oxygen species (ROS) act as important molecules and play pivotal ...

The APETALA2/Ethylene-Responsive Factor (AP2/ERF) superfamily of transcription factors (TFs) regulates physiological, developmental and stress responses. Most of the AP2/ERF TFs belong to the ERF family in both dicotyledonous and monocotyledonous plants. ERFs are implicated in the responses to both biotic and abiotic stress and occasionally impart multiple stress tolerance. Studies have reveale...

Plants are constantly challenged by various abiotic stresses that negatively affect growth and productivity worldwide. During the course of their evolution, plants have developed sophisticated mechanisms to recognize external signals allowing them to respond appropriately to environmental conditions, although the degree of adjustability or tolerance to specific stresses differs from species to ...

In post-genomic era, bioinformatic tools allow us to explore and reconstruct the precise gene interaction network. To deduce the function of uncharacterized gene, genetic network by co-regulatory analysis from an expression data is a foremost approach. In this study, we report comprehensive identification of co-expressed MYB gene modules in rice. MYB transcription factor family is involved in p...

Numerous stresses caused by complex environmental conditions, e.g., drought, heat, cold, salinity, strong light, UV, and heavy metals, negatively affect plant growth and lead to substantial crop losses worldwide. It is estimated that up to 50–70% of declines in crop productivity can be attributed to abiotic stress (Mittler, 2006). Abiotic stress, particularly drought and extreme temperatures, w...

Understanding the principles of abiotic and biotic stress responses, tolerance and adaptation remains important in plant physiology research to develop better varieties of crop plants. Better understanding of plant stress response mechanisms and application of knowledge derived from integrated experimental and bioinformatics approaches are gaining importance. Earlier, we showed that compiling a...
