Manipulation of the microRNA172 -AP2L2interaction provides precise control of wheat and triticale plant height

Abstract

AbstractTheREDUCED HEIGHT(RHT) dwarfing allelesRht-B1bandRht-D1bwere essential in the “Green Revolution” to optimize wheat plant height and increase grain yield. However, those alleles reduce coleoptile length limiting sowing depth, which triggered the search for alternative dwarfing genes. In this study, we engineered the interaction between miR172 andAP2L2genes to fine-tune wheat and triticale plant height without affecting coleoptile and first-leaf length.
