Abstract: AbstractMain conclusionWe demonstrate thatrbcLunderwent strong positive selection during the C3–C4photosynthetic transitions in PACMAD grasses, in particular the 3′ end of the gene. In contrast, selective pressures on other plastid genes vary widely and environmental drivers… read more here.

DOI: 10.1016/j.steroids.2016.12.004
Abstract: HIGHLIGHTSEpibrassinolide and the green light up‐regulate the transcription of plastid genes.Epibrassinolide elevates the content of cytokinins in the dark.Green light increases the content of brassinosteroids and zeatin. ABSTRACT In order to evaluate whether brassinosteroids (BS)… read more here.

Abstract: BACKGROUND AND AIMS Although the plastid genes are being largely used in phylogenetic studies, signals of positive selection have been scarcely investigated in grape family. The plastomes from 91 accessions of Vitaceae were examined to… read more here.
