Function

function

Involved in resistance to oxidative stress. Influences responses to reactive oxygen species (ROS) production. Regulates plastoglobules formation in thylakoids. Together with OSA1, regulates iron distribution within the chloroplast and mediates the oxidative stress response (PubMed:24117441).
Together with ABC1K8, influences chloroplast lipid synthesis/accumulation and modulates chloroplast membrane composition in response to stress (PubMed:25809944).

Phenotypes & Variants

Disruption phenotype

Larger plastoglobules associated with thylakoids characterized by VTE1 accumulation and high tocopherol content. The pale green double mutant atsia1 atosa1 accumulates ferritin and superoxides, exhibits an increased nonphotochemical quenching (NPQ), and have a reduced tolerance to reactive oxygen species (ROS) (PubMed:24117441).
Lower levels of the highly unsaturated lipid digalactosyldiacylglycerol (DGDG) and of different forms of monogalactosyldiacylglycerol (MGDG) and kaempferol. The abc1k7 abc1k8 double mutant accumulates strong levels of oxylipin-conjugated MGDG and DGDG (PubMed:25809944).
