Background Histone methylation modifies the epigenetic state of target genes to regulate gene expression in the context of developmental and environmental changes. Previously, we used a positive genetic screen to identify an Arabidopsis mutant, cli186, which was impaired in carbon and light signaling. Here, we report a deletion of the Arabidopsis histone methyltransferase SDG8 in this mutant (renamed...
The plastid gene psbD encodes D2, a photosystem II reaction center chlorophyll-binding protein. psbD is transcribed from a conserved chloroplast promoter that is activated by blue, white, or UV-A light. In this study, various forms of the barley (Hordeum vulgare L.) chloroplast psbD-LRP were fused to the uidA reporter gene and introduced into the tobacco (Nicotiana tabacum L.) plastid genome through...
