Comparative transcriptome analysis of multiple leaf color mutants reveals pathways and variations involved in controlling chloroplast development in cultivated peanut (Arachis hypogaea L.). Arachis hypogaea cultivar:Yuanza9102

Leaf-color mutations are widely reported in various plants in studying of chlorophyll biosynthesis and chloroplast development. However, identifying genes relevant to leaf-color changes in cultivated peanut is lagged due to its large complex allotetraploid genome. Here, we deploy comparative transcriptome analysis of three types of EMS-mutagenized leaf-color mutants, including albino mutants, etiolated mutants, and color-leaf mutants, to identify genes contribute to chloroplast development in cultivated peanut. Transcriptome of mutants derived from four lines and their corresponding wild-type progenitors were sequenced and aligned to the two diploid ancestors of cultivated peanut Arachis duranensis and Arachis ipaensis respectively to estimate expression levels of genes and to identify candidate genes responsible for the mutant phenotypes.
