PNP — Cicer arietinum

Summary

LOC101497377 (CaPNP) on chickpea chromosome 3 encodes a polyribonucleotide nucleotidyltransferase, a 3'-5' exoribonuclease with RNA-binding KH and S1 domains. It is associated with chloroplast and mitochondrial RNA processing, mRNA catabolism, and tRNA and rRNA processing. The gene is linked to chlorophyll and carotenoid anabolism, xanthophyll anabolism, and downregulation of the mevalonate-independent isopentenyl diphosphate biosynthetic pathway. It has been connected to pathogen resistance, chlorophyll and carotenoid accumulation, and fosmidomycin resistance. Localisation evidence places the product in the chloroplast stroma, mitochondria, and cytosol. Studies of related genes in other species link the family to carotenoid and protein content, disease tolerance, photochemical quenching, and responses to phosphorus deprivation and stress.
