Drought Stress in Horticultural Plants.

Drought stress tolerance can be reached through the selection of species tolerant to drought stress or by increasing the tolerance of sensitive species. Drought stress is one of the main factors limiting horticultural crops, especially in environments such as the Mediterranean basin, which is often characterized by sub-optimal water availability. Yang et al. [[1]] provide a review that focuses on the molecular mechanisms, and in particular on the main drought stress signals and signal transduction pathways in plants, as well as the functional and regulatory genes related to drought stress. Transcriptional analysis of photosynthesis, antioxidants, and drought-sensitive genes showed that VRM(Gg)1 increased transcripts more than CO6 under drought stress. [Extracted from the article]
