ZB8 — Oryza sativa Japonica

Summary

OsZB8 (OS04G0518100) on rice chromosome 4 encodes a protein with phenylalanine ammonia-lyase activity (EC 4.3.1.24), tyrosine ammonia-lyase activity, ammonia-lyase activity, and DNA-binding transcription factor activity, and belongs to the aromatic lyase and Phe_NH3-lyase domain families. The gene is associated with sheath blight resistance, bacterial blight resistance, resistance to root-knot nematode, lignin deposition, and disease responses. It has been linked to traits including seedling vigor, plant height, tiller number, leaf angle, photosynthetic rate, cold tolerance, salt tolerance, IAA content, pollen fertility, and germination rate. The product is also associated with biological processes such as L-phenylalanine breakdown, cinnamic acid anabolism, salicylic acid breakdown, lignin breakdown, hydrogen peroxide biosynthesis, and negative regulation of cytokinin signalling, and localises to the cytosol, cytoplasm, nucleus, and SCF complex.
