Broccoli variety with high levels of sulphur-containing compounds glucoraphanin

Broccoli variety with high levels of sulphur-containing compounds glucoraphanin

In an article  entitled, “Genetic regulation of glucoraphanin accumulation in Beneforté broccoli published in the recent issue of New Phytologist (2013) 198:1085-1095, Richard F. Mithen and 13 of his associates affiliated to different institutions, Richard Mithen at the Institute of Food Research in Norwich, UK, and his associates attributed a single gene called Myb28 to be most likely responsible for production of high levels of sulphur-containing compounds in new commercial varieties of broccoli.  The  team produced three hybrid lines by repeatedly crossing common broccoli (Brassica oleracea var. italica) with a wild related species, namely,  B. villosarich in glucoraphanin contributing to good  health. The  team’s analysis of the genetic makeup revealed that that the hybrids had all inherited the gene, called Myb28, that regulates glucoraphanin production. Earlier it was reported that this gene also regulates glucoraphanin production in the model plant Arabidopsis.
