Characterization of BRI1 homologs in maize. A, BRI1 protein domains. The region of BRI1a used for RNAi is indicated. ID, Island domain; TM, transmembrane domain. B, Phylogenetic analysis showed that there are five BRI1 homologs in maize, including three BRL genes and a maize-specific duplication of the BRI1 gene. C, Island domain and LRR 22 domain alignment of BRI1 homologs show that all maize homologs belong to the BRI1 family. D, Quantitative reverse transcription (qRT)-PCR expression analysis of BRI1 homologs in zmbri1-RNAi plants. Shoot tissue was collected from plants showing characteristic zmbri1-RNAi phenotypes at the approximately eight-leaf stage. bri1-RNAi(s) is the strong event, and bri1-RNAi(m) is a mild event. Bars show proportional expression of the genes in RNAi lines relative to wild-type siblings, with wild-type expression set to 1. ANOVA P values: *, P < 0.05; and **, P < 0.01.
