Epigenetic regulation mechanism of rain-borne astaxanthin accumulation

Rhodococcus pluvialis (H.

Recently, a research team led by Professor Huang Qing from Hefei Institute of Material Science, Chinese Academy of Sciences revealed the epigenetic regulation mechanism of the stimulating effect of low-temperature plasma (LTP) treatment on the accumulation of rain-borne astaxanthin

"Before, we found that low-temperature plasma can stimulate the growth of pluvialis H.

"Histone trimethylation occurs after low-temperature plasma treatment of algae cells.

After detecting hormones and transcription genes, the research team found that after LTP treatment, the levels of SLS and ABA in the algae increased significantly, and the expression of astaxanthin synthesis genes increased, especially one of the key points.

"So we conducted these experiments and proved that plasma stimulation is achieved by regulating h3k4me3 to increase the expression of CRTISO ," said LI lammei, the co-first author of the paper

This study explored the mechanism of LTP promoting algae growth and astaxanthin production from the perspective of epigenetics
