Development of Drought-Tolerant Transgenic Wheat: Achievements and Limitations.

Int J Mol Sci. 2019 Jul 8; 20(13). pii: E3350. doi: 10.3390/ijms20133350.


Crop yield improvement is necessary to keep pace with increasing demand for food. Due to climatic variability, the incidence of drought stress at crop growth stages is becoming a major hindering factor to yield improvement. New techniques are required to increase drought tolerancealong with improved yield. Genetic modification for increasing drought tolerance is highly desirable, and genetic engineering for droughttolerance requires the expression of certain stress-related genes. Genes have been identified which confer drought tolerance and improve plant growth and survival in transgenic wheat. However, less research has been conducted for the development of transgenic wheat as compared to rice, maize, and other staple food. Furthermore, enhanced tolerance to drought without any yield penalty is a major task of genetic engineering. In this review, we have focused on the progress in the development of transgenic wheat cultivars for improving droughttolerance and discussed the physiological mechanisms and testing of their tolerance in response to inserted genes under control or field conditions
