Shenzhen University's latest article: DNA methylation changes during tomato phosphorus deficiency

Tomato ( Solanum lycopersicum L.

Recently, the research group of Professor Huang Tengbo from the School of Life and Marine Sciences of Shenzhen University has published in Plant Biotechnology Journal , the authoritative journal of botany (a TOP journal in the first district of the Chinese Academy of Sciences , with an impact factor of 9.

This study identified an ethylene-induced and up-regulated Sly-miR164 precursor family member SlMIR164A from tomato, and created a SlMIR164A mutant slmir164a ^CR by CRISPR/Cas9 gene editing technology .

This study also revealed that inhibition of SlNAM2 / SlNAM3 in slmir164a ^CR by VIGS could delay fruit ripening and inhibit the accumulation of metabolites such as sugar and acid in fruit, further verifying that SlNAM2 / SlNAM3 mediates SlMIR164A in the fine regulation of fruit ripening and flavor formation.

Lin Dongbo , a postdoctoral fellow at the School of Life and Marine Sciences of Shenzhen University , is the first author of the paper, and Professor Huang Tengbo is the corresponding author of the paper
