CAT2 — Beta vulgaris subsp. vulgaris

Summary

BVRB_1G021080 (CAT2) on sugar beet chromosome Bvchr1_un.sca005 encodes a catalase, a haem-binding enzyme. The protein belongs to the catalase family and localises to the peroxisomal lumen, cytosol, nucleus and plasma membrane. This gene is associated with diverse biological processes including raffinose, oxalate, putrescine, xanthine and polyamine metabolism, cellular nitric oxide homeostasis, melanin anabolism, wound healing, nitrogen utilization, regulation of transport, downregulation of photosynthesis, and electron transfer. It is linked to numerous agronomic traits such as root yield, root weight and volume, plant height, flag leaf area, leaf area index, chlorophyll content, net photosynthetic rate, quantum yield, transpiration rate, stomatal resistance, sucrose and sugar content, protein and soluble protein content, proline and lignin content, seedling vigor, drought tolerance, and salt response. Studies of related genes in other species connect the family to catalase activity (EC 1.11.1.6).
