Dr. Ming-Hsiun Hsieh’s laboratory reported that nitrogen deficiency- and sucrose-induced anthocyanin biosynthesis was modulated by HISTONE DEACETYLASE15 (HDA15) in Arabidopsis. Nitrogen deficiency, high sucrose, and methyl jasmonate, but not H2O2 and phosphate starvation, enhanced anthocyanin accumulation by increasing histone acetylation and expression of anthocyanin biosynthetic and regulatory genes in the hda15 mutant (Fig. 1). HDA15 may modulate anthocyanin biosynthesis under certain stress conditions. The paper is published in the Journal of Experimental Botany (DOI: 10.1093/jxb/erac067), and the first author Hong-Sheng Liao is advised by Dr. Hsieh and Dr. Chien-Chih Yang of the Department of Biochemical Science & Technology at National Taiwan University.
