Chromatin interacting factor OsVIL2 increases biomass and rice grain yield Yang, Jungil Cho, Lae-Hyeon Yoon, Jinmi Yoon, Hyeryung Antt Htet Wai Hong, Woo-Jong Han, Muho Sakakibara, Hitoshi Liang, Wanqi Jung, Ki-Hong Jeon, Jong-Seong Koh, Hee-Jong Zhang, Dabing An, Gynheung Grain number is an important agronomic trait. We investigated the roles of chromatin interacting factor Oryza sativa VIN3-LIKE 2 (OsVIL2), which controls plant biomass and yield in rice. Mutations in OsVIL2 led to shorter plants and fewer grains whereas its overexpression (OX) enhanced biomass production and grain numbers when compared with the wild type. RNAsequencing analyses revealed that 1958 genes were up-regulated and 2096 genes were downregulated in the region of active division within the first internodes of OX plants. Chromatin immunoprecipitation analysis showed that, among the downregulated genes, OsVIL2 was directly associated with chromatins in the promoter region of CYTOKININ OXIDASE/ DEHYDROGENASE2 (OsCKX2), a gene responsible for cytokinin degradation. Likewise, active cytokinin levels were increased in the OX plants. We conclude that OsVIL2 improves the production of biomass and grain by suppressing OsCKX2 chromatin. 2018 http://hdl.handle.net/20.500.12678/0000000625 https://meral.edu.mm/records/625
