ESB1 — Brassica oleracea var. botrytis

Summary

BoESB1, located on chromosome 4 of cauliflower (Brassica oleracea var. botrytis), encodes a dirigent domain-containing protein. This gene is associated with macroautophagy, protein secretion, suberin biosynthetic process, autophagy, lignin anabolism, cell death, programmed cell death, and innate immunity. It is linked to the Casparian strip and nucleus. BoESB1 has been connected to zinc, sodium, calcium, and manganese accumulation, aliphatic suberin biosynthesis, water use efficiency, mineral accumulation, transpiration rate, and Casparian strip formation. Studies of related genes in other species link the family to increased suberin levels, disordered Casparian strip, and altered ion levels.
