RPT2 — Cicer arietinum

Summary

CaRPT2 (LOC101497023) on chickpea chromosome 2 encodes a member of the NPH3/RPT2-like protein family, containing NPH3 and BTB/POZ domains, and is annotated with FMN binding, blue light photoreceptor activity, microtubule binding, and protein serine/threonine kinase activity. The gene is associated with blue light signaling, chloroplast avoidance movement, regulation of stomatal movement, circadian rhythm, auxin and brassinosteroid signaling, protein ubiquitination, and proton transport regulation. It localizes to the plasma membrane, cytoplasm, nucleus, and plant-type vacuole. Associations include phototropism, chloroplast accumulation movement, leaf flattening, and plant growth. Trait associations link CaRPT2 to biomass yield, water use efficiency, days to flowering, germination rate, root mass density, stomatal resistance, low temperature stress response, leaf senescence, and phenolic compound content. Studies of related genes in other species connect the family to root phototropism, guard cell anion channel regulation, and chloroplast relocation.
