Recently, Xie Xianzhi, a researcher at the Rice Research Institute of Shandong Academy of Agricultural Sciences, and Sun Jianqiang and Kong Xiuying, a researcher at the Institute of Crop Science of the Chinese Academy of Agricultural Sciences, reported that PIL family transcription factors directly interact with SPLs and inhibit the tillering of wheat, rice and Arabidopsis.
The structure of plant height, tiller number and tiller angle is one of the important determinants of plant type of crops such as wheat and rice, and is closely related to yield
The phytochrome interaction factor PHYTOCHROME-INTERACTING FACTORs (PIFs) family, which was originally identified in Arabidopsis thaliana, plays a key role in the regulation of photomorphogenesis at the seedling stage
The study firstly analyzed the overexpression phenotype of wheat TaPIL1 and found that TaPIL1 inhibited wheat tillering by up-regulating the expression of TaTB1
Further identification of the function of rice OsPIL11 found that its overexpression and loss-of-function mutations reduced or increased the number of rice tillers, respectively, and this was achieved by regulating the expression of OsTB1
