Genomics Approaches for Crop Improvement against Abiotic Stress

Abstract EN

As sessile organisms, plants are inevitably exposed to one or a combination of stress factors every now and then throughout their growth and development.

Stress responses vary considerably even in the same plant species; stress-susceptible genotypes are at one extreme, and stress-tolerant ones are at the other.

Elucidation of the stress responses of crop plants is of extreme relevance, considering the central role of crops in food and biofuel production.

Crop improvement has been a traditional issue to increase yields and enhance stress tolerance; however, crop improvement against abiotic stresses has been particularly compelling, given the complex nature of these stresses.

As traditional strategies for crop improvement approach their limits, the era of genomics research has arisen with new and promising perspectives in breeding improved varieties against abiotic stresses.
