Drought stress in plants

What is it about?

Drought stress is the most important abiotic stress that constrains crop production and reduces yield drastically.Due to climate change and population booms, food security has become a global issue. To develop drought tolerant crop varieties knowledge of various genes involved in drought stress is required. In this review, we described the contributions of different techniques of functional genomics in the study of drought tolerant genes.

Why is it important?

Nowadays, global food security has becomes a major challenge due to the extreme changes to the climate and increases in the global population. Therefore, plants are growing under various kinds of unfavourable environmental stresses which are retarding the growth and yield. Drought stress is the most predominant abiotic stress making this situation worse. Thus, there is an urgent need of drought tolerant varieties of present cultivars.
