Genetic element (GENE)
last updated: 12 Jun 2014
Protein coding sequence
The gene avhppd-03 decodes the enzyme AvHPPD-03 which catalyses the formation of homogentisic acid, the aromatic precursor of plastoquinone and vitamin E biosynthesis . It has a low binding afinity for mesotrione, a herbicide that inhibits HHPD. Expression of AvHPPD-03 in plant cells confers tolerance to HPPD inhibitor herbicides such as mesotrione.
