Flavonoid genetics

Study. Its flavonoid chemistry is particularly well documented, the enzymology and genetics of the flavonoid pathway are well understood, and the molecnlar biological tools are available. 

Despite the morphological similarity of D. cannabina and D. glomerata, and their distinctive flavonoid profiles, an electrophoretic examination revealed an entirely different picture (Liston et al., 1989). Calculation of the mean genetic identity among populations of both species, based upon variation of enzymes coded for at 21 loci, yielded a value of 7=0.142. hitraspecifie genetic identities were 7=0.649 for D. cannabina and 0.847 for D.

Another area in which Arabidopsis genetics is proving to be useful is the study of the proposed role of flavonoids in regulating auxin transport. Several years ago, Jacobs and Rubery published the first evidence that flavonoids could specifically compete with naphthylphthalamic acid for binding to the auxin efflux carrier in etiolated zucchini hypocotyls.35 This finding was somewhat controversial, however, and no additional evidence for the connection between flavonoids and auxin transport was reported for some time. Brown et al. have now used Arabidopsis flavonoid mutants to generate new evidence in support of a role for flavonoids in the regulation of polar auxin movement.6 These experiments took...
