A senescence-related gene <i>CpSRG1</i>, which belongs to the 2OG-Fe(II) dioxygenase superfamily, was characterized from wintersweet, and the phylogenetic relationship of CpSRG1 with homologs from other species was investigated. The expression analysis by qRT-PCR (quantitative real-time PCR) indicated that <i>CpSRG1</i> is abundant in flower organs, especially in petals and stamens, and the highest expression of <i>CpSRG1</i> was detected in stage 6 (withering period). The expression patterns of the <i>CpSRG1</i> gene were further confirmed in <i>CpSRG1pro::GUS</i> (<i>β-glucuronidase</i>) plants, and the activity of the <i>CpSRG1</i> promoter was enhanced by exogenous Eth (ethylene),International journal of molecular sciencesOverexpression of a Senescence-Related Gene <i>CpSRG1</i> from Wintersweet (<i>Chimonanthus praecox</i>) Promoted Growth and Flowering, and Delayed Senescence in Transgenic <i>Arabidopsis</i>.PMC9696086Natural Science Foundation Project of Chongqing (No. cstc2020jcyj-msxmX0754)No. 32101575National Natural Science Foundation of China No. 32101575National Natural Science Foundation of China No. 31971711cstc2020jcyj-msxmX0754No. 31971711Li GSui SLuo JCao YWang XLiu DHuang RLi MfalseOverexpression of a Senescence-Related Gene <i>CpSRG1</i> from Wintersweet (<i>Chimonanthus praecox</i>) Promoted Growth and Flowering, and Delayed Senescence in Transgenic <i>Arabidopsis</i>.Plant senescence is a complex process that is controlled by developmental regulation and genetic programs.
