APETALA2 functions as a temporal factor together with BLADE-ON-PETIOLE2 and MADS29 to control flower and grain development in barley

Shoesmith JR et al. (2021)  

Using advanced molecular tools and gene-editing techniques, our team showed that HvAP2 regulates multiple events during floret and grain development, including the formation of floret hulls which protect grain and the development of the calorie-rich starchy endosperm within grain.
