ZB8 — Oryza sativa Japonica

Summary

OsZB8 (OS04G0518400) encodes a protein with phenylalanine ammonia-lyase activity (EC 4.3.1.24), tyrosine ammonia-lyase activity, ammonia-lyase activity, amino acid binding, protein dimerization activity, DNA-binding transcription factor activity, and protein binding. The gene is associated with sheath blight resistance, bacterial blight resistance, resistance to root-knot nematode, lignin deposition, and disease responses. It is associated with downregulation of chlorophyll anabolism, salicylic acid breakdown, cinnamic acid anabolism, hydrogen peroxide biosynthetic process, and drought recovery. Associations include IAA content, seedling vigor, UV light sensitivity, leaf color, leaf angle, tiller number, plant height, cold tolerance, photosynthetic rate, and salt tolerance. The protein localizes to the cytosol, cytoplasm, nucleus, and SCF complex. Studies of related genes in other species link the family to UV stress resistance, herbivore defense, and chlorogenic acid accumulation.
