Article: Low temperature tolerance and cold acclimation for seedlings of three Mojave Desert Yucca species exposed to elevated CO2
Temperature and Humidity As adesert plant, yucca is drought tolerant and withstands temperatures of 90°F and higher. Yucca plant also survives below freezing temperatures, with desert nights cooling to the 30°F range. The perennial also withstands temperatures as low as 10°F in northern state...
and the possible mechanisms have been attributed to the higher level of auxin produced by YUC (1) to improve the root architecture, which is one of the determining factors for plant drought tolerance; (2) to rapidly induce the drought- and/or ABA-responsive genes; (3) to maintain the ROS...
AtYUC6 and AtYUC7 were reported to confer drought tolerance depending on distinct mechanisms [10,29]. AtYUC6 played a dual role in regulating plant growth as an auxin biosynthetic enzyme and conveying drought response as a thiol-reductase (TR)-like protein, which functioned through ROS ...
