Teosinte Branched 1 modulates tillering in rice plants
Tillering is an important trait of cereal crops that optimizes plant architecture for maximum yield. Teosinte Branched 1 (TB1) is a negative regulator of lateral branching and an inducer of female inflorescence formation in Zea mays (maize). Recent studies indicate that TB1 homologs in Oryza sativa...

| description | Tillering is an important trait of cereal crops that optimizes plant architecture for maximum yield. Teosinte Branched 1 (TB1) is a negative regulator of lateral branching and an inducer of female inflorescence formation in Zea mays (maize). Recent studies indicate that TB1 homologs in Oryza sativa (rice), Sorghum bicolor and Arabidopsis thaliana act downstream of the auxin and MORE AUXILIARY GROWTH (MAX) pathways. However, the molecular mechanism by which rice produces tillers remains unknown. In this study, transgenic rice plants were produced that overexpress the maize TB1 (mTB1) or rice TB1 (OsTB1) genes and silence the OsTB1 gene through RNAi-mediated knockdown. Because lateral branching in rice is affected by the environmental conditions, the phenotypes of transgenic plants were observed in both the greenhouse and the paddy field. Compared to wild-type plants, the number of tillers and panicles was reduced and increased in overexpressed and RNAi-mediated knockdown OsTB1 rice plants, respectively, under both environmental conditions. However, the effect was small for plants grown in paddy fields. These results demonstrate that both mTB1 and OsTB1 moderately regulate the tiller development in rice. |
