Summation

TILLER ANGLE CONTROL 1 (TAC1) is involved in the regulation of the tiller angle. It promotes horizontal shoot growth. TAC1 and LAZY1 play opposite functions in the regulation of tiller growth angle. The overexpression of TAC1 results in an enlarged tiller angle, thus a spread-out plant architecture. The cultivated japonica rice genotypes contain a point mutation in the 3'-splice site of TAC1's fourth intron (?GGGA?) that suppresses TAC1 expression, causing a compact plant architecture (Zhu et al., 2021). In contrast, wild rice and several indica rice accessions (with spread-out tillers) contain ?AGGA? in the 3'-splice site of TAC1's fourth intron (Dong et al., 2016). Transgenic RNAi plants that show silencing of TAC1 exhibit erect tillers with a very small tiller angle (Baisheng et al., 2007). TAC1 promoter has binding sites for the three TFs including ARF15, OsHOX1, and OsHOX28 (Naithani et al. (2024);analysis conducted by the Plant Reactome Biocurator)
