oil content is one of the most important components of rape oil production, and with the continuous mining of the potential of oil content in modern breeding, it is more and more difficult to improve the oil content of varieties. On the basis of the genetic study of oil content in rape, the team made a breakthrough in the research on the new mechanism of oil content maternal regulation from the cytogenetic effect, screened two varieties with significant positive and negative effects on oil content, and identified the positive oil content effect of the specific gene orf188 to control the cytostic mass, and over-expression of the gene can greatly increase the oil content. Studies have shown that orf188 is a gene endement to nap-like rape varieties and is a newly evolved chimed gene.
The team has been systematically studying the maternal regulation of rape seed traits for more than ten years, and the discovery of the mechanism of oil content of cytogenetic gene regulation seeds is another new way for the team to regulate seed grain weight and oil content after the discovery of peel development, further enriching and perfecting the theory of maternal regulation of seed traits, and providing reference for the analysis of other crop-like cytokine effects.
