L. tridentata, or desert creosote bush, is a xerophytic C3 plant native to the American Southwest, and is known to have evolutionarily developed sophisticated cellular mechanisms to deal with periods of intense abiotic stress. Particularly, complex signaling pathways in L. tridentata allow it to survive in periods of severe water deficiency. Through the findings of Zou et al. [5,6], LtWRKY21 synergistically works with abscisic acid (ABA) to transactivate both ABA-inducible HVA1 and HVA22 promoters. In addition, as ABA and gibberellic acid (GA) pathways are known to act antagonistically. Expectantly, the findings of Zou et al. suggest that LtWRKY21 activates ABA …
