Pathology & Biotechi

Disruption phenotypei

No visible phenotype at the levels of the whole plant or chloroplast ultrastructure; due to the redundancy with PORB. Porb and porc double mutants have a seedling-lethal pale-yellow xantha phenotype at the cotyledon stage, contain only small amounts of Chla, and possess chloroplasts with mostly unstacked thylakoid membranes.1 Publication
