CER1 (TRAESCS1B02G168400) — triticum aestivum

Summary

TRAESCS1B02G168400 (TaCER1) on chromosome 1B encodes a decarbonylase with iron-binding and redox activity, belonging to the fatty acid hydroxylase and sterol desaturase-related families. The gene is associated with alkane, very-long-chain fatty acid, cutin, and wax biosynthesis, as well as aldehyde breakdown, cuticle development, pollen exine formation, anther and tapetum development, and responses to stress, jasmonic acid, wounding, salinity, and fungal defence. TaCER1 is linked to traits including plant height, root length, flowering time, male sterility, trichome morphology, ethylene sensitivity, lignin biosynthesis, IAA content, vigor, disease tolerance, low-temperature stress response, and white-backed planthopper response. Phenotypic associations include grain yield, cuticular wax production and permeability, freezing and dehydration tolerance, cold tolerance, immunity, and CLCuV resistance. Studies of related genes in other species connect the family to pollen and tapetum development, drought resistance, alkane synthesis, wax crystallization, and whitefly resistance.
