A Null Mutation in the First Enzyme of Flavonoid Biosynthesis Does Not Affect Male Fertility in Arabidopsis
The Plant Cell
Flavonoids are a major class of secondary metabolites that serves a multitude of functions in higher plants, including a recently discovered role in male fertility. Surprisingly, Arabidopsis plants deficient in flavonoid biosynthesis appear to be fully fertile. Using RNA gel blot analysis and polymerase chain reaction-based assays, we have shown that a mutation at the 3' splice acceptor site in the Arabidopsis chalcone synthase gene completely disrupts synthesis of the active form of thedoi:10.1105/tpc.8.6.1013 pmid:8672888 fatcat:hzlozcxqwndhhdo2donf2uws5q
