CEO — Brassica juncea

Summary

BjCEO (BJUUNNG08630S) on chromosome JAATWR010000277.1 of Indian mustard encodes a WWE_RCD1 domain-containing protein with NAD ADP-ribosyltransferase activity, transcriptional co-regulator function, and multiple additional molecular activities including mRNA 5'-UTR binding, mannan synthase activity, and protein kinase activity. The gene is associated with upregulation of cellular response to oxidative stress, chlorophyll breakdown, and shade avoidance, as well as downregulation of immune response. It has been linked to numerous traits including shoot system boron content, sodium uptake, carotenoid content, iron concentration, vegetative vigor, cytoplasmic male sterility, and responses to zinc and UV-B light. The gene localizes to chloroplast nucleoid, thylakoid, chloroplast envelope, ER membrane, plasmodesma, and nuclear speck. Related genes in other species are associated with salt tolerance, ion homeostasis, defense response, shade avoidance, and drought stress tolerance.
