• Du13 encodes a C2H2 zinc‐finger protein that regulates Wxb pre‐mRNA splicing and microRNA biogenesis in rice endosperm

    Summary
    Amylose content is a crucial physicochemical property responsible for the eating and cooking quality of rice grain and is mainly controlled by the Waxy gene. Previous studies have identified several Dull genes that modulate the expression of the Wx b allele in japonica rice by affecting the splicing efficiency of the Wx b pre-mRNA. Here, we uncover dual roles for a novel Dull gene in pre-mRNA splicing and microRNA processing. We isolated the dull mutant, du13, with a dull endosperm and low amylose content. Map-based cloning showed that Du13 encodes a C 2 H 2 zinc-finger protein...
