Abstract In recent years, some super hybrid rice varieties were bred with strong culms and large panicles, which are mainly
contributed by the ipa1-2D locus. A gain-of-function allele of OsSPL14 is the ipa1-2D and it can greatly increase
the panicle primary branch number. However, the key downstream genes mediating this trait variation are not
fully explored. In this study, we developed high-quality near-isogenic lines (NILs) with a difference of only
30 kb chromosomal segment covering the ipa1-2D locus. Using the NILs, we explored the impact of ipa1-2D
on five sequential stages of early inflorescence development, and found that the locus can… More >
