WebSep 14, 2016 · Regardless of their direct role as species barriers, cytonuclear incompatibilities manifest fundamental and theoretically widespread processes of nuclear and organellar coevolution. WebJun 10, 2024 · The researchers showed that the cause of the incompatibility was light-dependent misregulation of the chloroplast psbB operon. Unlike wild-type plants, AB-I plants could not acclimate to high light by increasing chlorophyll content and redox-active components of the electron transport system.
