Abstract

To date studies revealed that MYB28 intensively involved biosynthesis of GSLs, there is no direct evidence of MYB28 in glucoraphanin (GR) biosynthesis of broccoli. Furthermore, Agrobacterium (Agro)-infiltration also induced GSLs in Arabidopsis. However, there is no information regarding Agro-dependent GR accumulation in broccoli. We revealed that over-expression of BroMYB28 could accumulate GR, and Agro-infiltration is also enough to induce the accumulation of GR in broccoli. From our results, it is suggested that they used different regulatory mechanisms;BroMYB28 over-expression induced both BroMYB28 and BroMYB29 (Bol008849-like) transcripts;Agro-infiltration induced only BroMYB29 (Bol008849-like) transcripts.
