ARF — Pisum sativum

Summary

PsARFB1B (PSAT7G171640) on chromosome 7LG7 of garden pea encodes a small GTPase of the ARF family, with GTPase activity, GTP binding, protein kinase activity, and blue light photoreceptor activity. It is associated with blue light signaling, chloroplast accumulation and avoidance movements, auxin transport, intracellular protein transport, regulation of proton transport and stomatal movement, circadian rhythm, and protein autophosphorylation. The gene is linked to phototropism responses, biomass yield, water use efficiency, days to flowering, root mass density, lateral root length, leaf senescence, low temperature stress response, viral disease response, phenolic compound content, and stomatal resistance. Related genes in other species are linked to phototropism, chloroplast relocation, stomatal opening, drought tolerance, and guard cell anion channel regulation.
