BIP — Phaseolus vulgaris

Summary

PHAVU_002G328904, designated PvBIP, encodes a member of the Hsp70 family of molecular chaperones, containing a nucleotide-binding domain and a peptide-binding domain. The gene is associated with protein folding in the endoplasmic reticulum, the unfolded protein response, and ERAD pathway. PvBIP has been linked to diverse traits including seed coat color and pattern, root hair length and development, leaf senescence, flowering time, temperature stress responses, osmotic sensitivity, auxin and abscisic acid sensitivity, stomatal resistance, disease tolerance, and pollen fertility restoration. It is also connected to processes such as pigmentation, polar nucleus fusion, root hair tip growth, and actin filament-based movement. Studies of related genes in other species link the family to cadmium stress tolerance, seed germination, embryo viability, and basal defense.
