The Oil Institute of the Chinese Academy of Agricultural Sciences deciphered the anti-aging code for sesame seeds

Recently, the Chinese Academy of Agricultural Sciences
Oil Crops
Research Institute, led by the Institute, and Shenzhen Huada
gene
jointly carried out the
sesame
genome deciphering work was successfully completed. The study analyzed the formation mechanism of sesame seeds with high oil content and the characteristic
antoxidant
, anti-aging functional component sesame, and the results have been published online in the internationally famous journal
Genome Biology
).According to Zhang Xiurong, project host and researcher at the

Institute of Agricultural Sciences of China, the research team of the project showed that the sesame genome size was about
337-357Mb through fluid cytometer testing and sequencing analysis.
contains about
,148
genes, of which
84%
are annotated. The completion of the project, which makes sesame the second species of
Lamiales
, sequenced after spirulina, is of great significance for plant evolution and comparative biology research.sesame oil content of up to
65%,
high oil content and smaller genome, so that sesame seeds become an important species to study grease synthesis. The team found that although the total number of sesame oil synthesis genes was small, the genes associated with fat molecular transport
LTP1
expanded significantly compared to soybeans, while the genes
LOX
and
LAH
associated with fat degradation contracted significantly, resulting in a high oil content of sesame seeds. The researchers also found that differences in the oil content of sesame varieties were mainly due to differences in gene expression in the early stages of seed development (
10
days or so). Sesame oil lasts significantly longer than other cooking oils because sesame contains the special substance sesame. Sesame is highly antioxidant and can increase the stability of oil, which has been clinically proven to treat cancer and cardiovascular diseases.
