BolAG-BolRPI2-BolBAM4 Module Regulates the Bolting of Curd by Modulating Starch Metabolism in Broccoli (Brassica oleracea var. italica).

ABSTRACT: The curd is a unique indeterminate inflorescence structure, which is the most important edible organ of broccoli. Premature bolting of the curd is a major factor that limits the yield and marketability of broccoli. However, the formation and development of broccoli curd, especially the bolting of curd, remain poorly understood. In this study, BolAG, a homologous gene of the floral development gene AtAG, was highly expressed in curd and floral organ of broccoli. Overexpression of BolAG in broccoli significantly promoted curd development, leading to early bolting. Correspondingly, RNA interference (RNAi) of BolAG resulted in arrested curd development, leading to delayed or even absent bolting. Physiological analyses indicated that BolAG-overexpressing broccoli exhibited higher starch and sol
