Monodehydroascorbate reductase 2 and dehydroascorbate reductase 5 are crucial for a mutualistic interaction between Piriformospora indica and Arabidopsis

Ascorbate is a major antioxidant and radical scavenger in plants. Monodehydroascorbate
reductase (MDAR) and dehydroascorbate reductase (DHAR) are two enzymes of the
ascorbate–glutathione cycle that maintain ascorbate in its reduced state. MDAR2
(At3g09940) and DHAR5 (At1g19570) expression was upregulated in the roots and shoots
of Arabidopsis seedlings co-cultivated with the root-colonizing endophytic fungus
Piriformospora indica, or that were exposed to a cell wall extract or a culture filtrate from the …
