Description
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.
