Ascorbate deficiency can limit violaxanthin de-epoxidase activity in vivo.

Plant physiology - 1 Mar 2002

Müller-Moulé Patricia, Conklin Patricia L, Niyogi Krishna K

Abstract excerpt

As a response to high light, plants have evolved non-photochemical quenching (NPQ), mechanisms that lead to the dissipation of excess absorbed light energy as heat, thereby minimizing the formation of dangerous oxygen radicals. One component of NPQ is pH dependent and involves the formation of zeaxanthin from violaxanthin. The enzyme responsible for the conversion of violaxanthin to zeaxanthin is violaxanthin...
