TN2 — Cicer arietinum

Summary

CaTN2 (LOC101497758) on chickpea chromosome 5 encodes a protein with TIR, NB-ARC, and leucine-rich repeat domains, and is associated with ATP hydrolase, NADP nucleosidase, DPNase, lipase, DNA-binding transcription factor, and phosphoinositide binding activities. This gene is associated with defense responses including systemic acquired resistance via salicylic acid signaling, positive regulation of the hypersensitive response, callose deposition, and responses to Gram-negative bacteria, viruses, insects, ozone, UV, and hypoxia. It is linked to regulation of stomatal closure, hydrogen peroxide metabolism, leaf abscission, root meristem size, and lateral root development. Associations with agronomic traits include seed yield, biomass yield, water use efficiency, anthocyanin content, root thickness, and tolerance to biotic and abiotic stresses such as bacterial wilt, powdery mildew, low temperature, oxidative stress, and aluminum toxicity.
