6. CONCLUSIONS
There were significant differences in circRNA expression in rice grains
at different stages of rice development, and there were also changes in
circRNA styles. Through enrichment analysis of different databases, it
was found that circRNA had a certain degree of influence on hormone
synthesis factors, helicase and sod-related enzymes, and ABA metabolism,
which further affected sucrose decomposition, starch synthesis and
metabolism, and finally affected grain filling and grain quality.
