TN2 — Cicer arietinum

Summary

CaTN2 (LOC101498509) 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, and transcription factor activities. It is associated with defense responses to Gram-negative bacteria, viruses, and insects, systemic acquired resistance via salicylic acid signaling, positive regulation of the hypersensitive response and programmed cell death, and regulation of hydrogen peroxide metabolism, stomatal closure, and leaf abscission. The gene is linked to responses to UV, ozone, hypoxia, and singlet oxygen, as well as downregulation of lateral root development and root meristem size regulation. Associations with agronomic traits include biomass yield, seed yield, water use efficiency, disease tolerance, anthocyanin content, low temperature and oxidative stress responses, root thickness, and plant cell size.
