Description | TAC1 (Tiller Angle Control 1) was mapped to a 35-kb region on chromosome 9 using a large F2 population from crosses between an indica rice, IR24 (spread-out plant architecture) and an japonica introgressed line, IL55 (compact plant architecture with erect tillers). TAC1 gene harbors three introns in its coding region and a fourth 1.5-kb intron in the 3-untranslated region. A mutation in the 3'-splicing site of the 1.5-kb intron from "AGGA" to "GGGA" decreases the level of tac1, resulting in a compact plant architecture with a tiller angle close to zero. tac1 mutation "GGGA" was present in 88 compact japonica rice accessions and TAC1 with "AGGA" was present in 21 wild rice accession and 43 indica rice accessions with the spread-out form. Change in the tiller angle is driven by growth orientation of the tiller base. |
