Foliar application of allantoin reinforces antioxidant defense and glyoxalase systems to confer tolerance against arsenic toxicity in rice (Oryza sativa L.).

ABSTRACT:

Background

Arsenic (As) contamination is a pressing global challenge that substantially restricts crop productivity and growth due to its increasing prevalence in agricultural soils. Allantoin, a well-characterized plant metabolite, has not been thoroughly explored for its role in mitigating As-induced oxidative stress. This research explored the protective effects of foliar-applied allantoin in rice (Oryza sativa L. cv. BRRI dhan75) exposed to sodium arsenate (0.25 mM). At 10 days after transplanting plants subjected to As, with two allantoin doses (0.5 and 1.0 mM) applied as foliar sprays at 5-day intervals.

Results

Arsenic stress significantly inhibited growth, leaf expansion, chlorophyll content and water balance which reduced biomass accumulation, while elevating oxidat
