Designed ABA receptor agonists: a New Tool to Improve Crop Quality

Xuanming Liu, Lan Li, Bin Li, Jiao Lei, Xiushan Li

Unfriendly environments like drought, cold or any other properties stress lead to a certain reduction of crop yield and quality. Abscisic acid (ABA), as an important plant hormone, plays a very important role in plant growth and resisting plant stress responses. The discovery of ABA crystal structure is a very critical event and provide a very important role for ABA signaling pathways to be exposed to us more clearly. In this process, the screening of ABA receptor agonists played a decisive role in the analysis of ABA crystal structure. Further, various ABA receptor agonists have been screened out, and their functions have also been analyzed. Together, structures studies suggest a detailed mechanism for ABA and receptor binding and regulation of downstream ABA signal pathway, which provide a thought for improve crop yield and quality through the rational utilize the designed ABA agonists.
