Screening of key genes responsible for Pennisetum setaceum 'Rubrum' leaf color using transcriptome sequencing.

ABSTRACT: Pennisetum setaceum 'Rubrum' is an ornamental grass plant that produces purple leaves in high-light environments and light purple or green leaves in low-light environments, the latter of which greatly reduces its aesthetic appeal. Therefore, we aimed to identify the key genes associated with leaf coloration and elucidate the molecular mechanisms involved in the color changes in P. setaceum 'Rubrum' leaves. We performed transcriptome sequencing of P. setaceum 'Rubrum' leaves before and after shading. A total of 19,043 differentially expressed genes were identified, and the numbers of upregulated and downregulated genes at T1 stage, when compared with their expression at the T0 stage, were 10,761 and 8,642, respectively. The possible pathways that determine P. setaceum 'Rubrum' leaf color in
