RBOHF — Cicer arietinum

Summary

LOC101511451 (CaRBOHF) on chickpea chromosome 6 encodes a respiratory burst oxidase homolog protein with NADPH oxidase and EF-hand calcium-binding domains, and exhibits NAD(P)H oxidase H2O2-forming, calcium-dependent protein serine/threonine kinase, peroxidase, and calcium ion binding activities. It is associated with the respiratory burst involved in defense response, H2O2 biosynthetic process, regulation of stomatal opening and closure, carbohydrate homeostasis, osmolarity sensing, defense response by callose deposition, and ethene mediated signalling pathway. The gene is linked to traits including biomass yield, seed yield, photosynthetic rate, water use efficiency, transpiration rate, leaf elongation, root thickness, flowering time, and responses to salt, osmotic, and low temperature stress. It is also connected to hydrogen peroxide accumulation, salt stress tolerance, disease resistance, and ROS signaling. Related genes in other species link the family to guard cell aperture, abscisic acid signaling, and hypoxia tolerance.
