MRP3 — Cicer arietinum

Summary

LOC101506588 (CaMRP3, also known as ABCC3) on chickpea chromosome 2 encodes an ATP-binding cassette (ABC) transporter of the MRP/ABCC subfamily, possessing ABC transporter domains and ATP hydrolase activity. The protein is annotated with chlorophyll catabolite transmembrane transporter, GS-X pump, aluminium ion transporter, and UDP-glucose transmembrane transporter activities. It localises to the tonoplast, vacuolar membrane, vesicle membrane, and plasmodesmata. CaMRP3 is associated with aluminium ion detoxification and transport, UDP-glucose and phosphate transmembrane transport, glutathione metabolism, and responses to oxidative stress and other organisms. The gene is linked to leaf necrosis, seed weight, and chlorophyll content traits, as well as responses to ailanthone stress and bleomycin resistance. Related genes in other species connect the family to cadmium tolerance, accumulation, and root-to-shoot translocation, as well as heavy metal and herbicide stress responses.
