However, studies of the connection between the vital environmental factors \u2013 light and the significant endogenous gasotransmitter \u2013 H2S, is lacking. Here, the seedlings of foxtail millet were used to reveal the mechanism of light regulation in H2S generation. Results showed that seedling hypocotyl elongation was promoted by H2S, but inhibited by HA under dark or white light condition. H2S contents in hypocotyl increased at first under red, blue or white light then decreased, and the duration of increase under white light was longer than under red or blue light. The activity of cysteine desulfhydrases, which catalyse H2S generation, was increased by red light but decreased by blue and white light. The expressions of cysteine desulfhydrases coding genes LCD1 and LCD2 were promoted by red or white light, but inhibited by blue light. In contrast, DES gene was promoted by white light but inhibited by red or blue light. In addition, the activities of LCDs were regulated by the phosphorylation mediated by photoreceptors PHYB and CRY1\/CRY2. Finally, there are two pathways of light regulating H2S production, including a rapid process that involves the modification of phosphorylation on LCDs protein mediated by photoreceptors directly or indirectly, as well as a slower process that involves in regulating the expressions of LCDs and DES genes. This discovery has potential value for the application of H2S in agricultural production protecting the crops from unsuited light condition.<\/jats:p>","DOI":"10.1071\/fp19079","type":"journal-article","created":{"date-parts":[[2019,6,25]],"date-time":"2019-06-25T07:53:36Z","timestamp":1561449216000},"page":"916-924","source":"Crossref","is-referenced-by-count":15,"title":["Light regulates hydrogen sulfide signalling during skoto- and photo-morphogenesis in foxtail millet"],"prefix":"10.1071","volume":"46","author":[{"given":"Zhiqiang","family":"Liu","sequence":"first","affiliation":[{"name":"ASchool of Life Science, Shanxi University, Taiyuan 030006, China."},{"name":"CShanxi Key Laboratory for Research and Development of Regional Plants, Taiyuan 030006, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunyu","family":"Cao","sequence":"additional","affiliation":[{"name":"ASchool of Life Science, Shanxi University, Taiyuan 030006, China."},{"name":"CShanxi Key Laboratory for Research and Development of Regional Plants, Taiyuan 030006, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yawen","family":"Li","sequence":"additional","affiliation":[{"name":"ASchool of Life Science, Shanxi University, Taiyuan 030006, China."},{"name":"CShanxi Key Laboratory for Research and Development of Regional Plants, Taiyuan 030006, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangdong","family":"Yang","sequence":"additional","affiliation":[{"name":"ASchool of Life Science, Shanxi University, Taiyuan 030006, China."},{"name":"BDepartment of Chemistry and Biochemistry, Laurentian University, Sudbury, ON P3E 2C6, Canada."},{"name":"CShanxi Key Laboratory for Research and Development of Regional Plants, Taiyuan 030006, China."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8428-3399","authenticated-orcid":true,"given":"Yanxi","family":"Pei","sequence":"additional","affiliation":[{"name":"ASchool of Life Science, Shanxi University, Taiyuan 030006, China."},{"name":"CShanxi Key Laboratory for Research and Development of Regional Plants, Taiyuan 030006, China."},{"name":"DCorresponding author.
