Disruption of TaCYP707A-6B showed enhanced drought tolerance but also decreased fertility. Expression of TaCYP707A-6B is negatively associated with H3K27me3 level....Blocking the CTCTGYTY motif by dead Cas9 (dCas9) maintained a high level of H3K27me3 on the CYP707A gene, while decreasing its expression level leading to enhanced drought tolerance in both wheat and Arabidopsis....Therefore, our study provides a novel approach to improve plant drought tolerance by manipulating an evolutionarily conserved cis-element bound by histone demethylases in the intron of CYP707A genes.

Higher proline accumulation under drought suggested better drought tolerance than salinity in these cultivars. Photosynthetic efficiency (Fv/Fm) declined under salinity and drought stress in all cultivars, with drought causing a more significant reduction.
NAC Transcription Factor LpNAC22 Positively Regulates Drought Tolerance in Perennial Ryegrass [0.03%]
NAC转录因子LpNAC22通过正向调节渗透胁迫/osmotic stress相关基因的表达来提高多年生黑麦草的耐旱性

Therefore, it is important to identify the essential genes that determine drought tolerance in perennial ryegrasses. In this paper, we isolated a drought-induced NAC transcription factor LpNAC22....LpNAC22 overexpression plants had enhanced drought tolerance and reduced cell membrane damage, whereas the knockdown of LpNAC22 in perennial ryegrass reduced plant drought tolerance and led to aggravated cell membrane damage....Furthermore, we demonstrated that overexpression of LpLEA1 and LpLEA2-1 in Arabidopsis enhanced drought tolerance and reduced cell membrane damage under drought conditions.
WOX11-OsPRX130 module confers rice drought tolerance by maintaining ROS homeostasis in rice root [0.03%]
WOX11-OsPRX130模块通过在水稻根部维持ROS稳态来提高水稻抗旱性

In this study, we found that WOX11 directly binds to the promoter of the peroxidase gene OsPRX130, thereby enhancing drought tolerance by regulating CR growth. Notably, OsPRX130 is predominantly expressed in rice roots and its expression is induced by drought stress....Knockout of OsPRX130 inhibited CR growth by reducing ROS levels, ultimately compromising the drought tolerance in rice....More importantly, our results deepen our understanding of how WOX11 regulates root development to enhance drought tolerance in rice and provide an alternative breeding strategy using WOX11 to control root system architecture for developing crop varieties with high drought adaptability.
Myosin XI coordinates ABA-induced stomatal closure via microtubule stability and ROS synthesis in drought-stressed Arabidopsis [0.03%]
