Regulation of biosynthetic genes and antioxidant properties of vitamin B₆ vitamers during plant defense responses

2005-06-01

Abstract excerpt

Vitamin B6, an essential cofactor in enzymatic reactions, has only recently been linked to cellular oxidative stress. We investigated the role of this vitamin as an antioxidant in oxidative responses linked to plant defense. B6 vitamers effectively quenched superoxide and had antioxidant activity when assayed in vitro. The de novo B6 biosynthetic genes (PDX1 and PDX2) were identified in Nicotiana tabacum cv. 'Burl...
