PSE1 — Brassica oleracea var. botrytis

Summary

BoPSE1, located on chromosome 3 of cauliflower (Brassica oleracea var. botrytis), encodes a protein containing an LRAT domain. The gene is associated with cellular response to lead ion, lead ion transport, phytochelatin anabolism, response to lead ion, and regulation of gene expression, and its product localises to the cytoplasm. Overexpression of PSE1 has been linked to lead accumulation and lead tolerance. Studies of related genes in other species connect the family to lead sensitivity with growth defects and Pb content, though these associations are not yet established in cauliflower.
