Low glucosinolate pennycress meal and methods of making

A pennycress seed comprising:

• (i) at least one loss-of-function mutation in an endogenous pennycress gene encoding the polypeptide of SEQ ID NO:
• 161 or an allelic variant thereof, wherein said loss-of-function mutation reduces expression of said polypeptide or reduces transcription factor activity of said polypeptide;
• or (ii) at least one transgene or genome rearrangement that suppresses expression of at least one endogenous pennycress gene that encodes the polypeptide of SEQ ID NO:
• 161 or an allelic variant thereof;
• wherein said allelic variants of SEQ ID NO:
• 161 have at least 95% sequence identity to SEQ ID NO:
• 161 and wherein said seed exhibits a reduction in sinigrin content in comparison to sinigrin content of a control seed which lacks said loss-of-function mutation, said transgene, or said genome rearrangement.
