ESB1 — Brassica oleracea var. botrytis

Summary

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