TN2 — Phaseolus vulgaris

Summary

PHAVU_001G093900 (PvTN2) on French bean chromosome 1 encodes a protein with domains including NB-ARC, leucine-rich repeats, and a winged-helix DNA-binding domain. The product exhibits ATP hydrolase, NADP nucleosidase, lipase, and DNA-binding transcription factor activities, and binds ADP, ATP, phosphoinositides, and identical proteins. PvTN2 is associated with defense responses to Gram-negative bacteria, viruses, and insects, systemic acquired resistance via salicylic acid signaling, hypersensitive response and programmed cell death, regulation of hydrogen peroxide metabolism, stomatal closure, leaf abscission, and responses to UV, ozone, hypoxia, and singlet oxygen. It localizes to the endomembrane system, ER, Golgi, mitochondria, cytosol, and vesicles. The gene is linked to traits including biomass yield, seed yield, water use efficiency, anthocyanin content, root thickness, disease tolerance, and responses to low temperature, oxidative stress, and aluminum.
