Growth inhibition of arable weeds by cerato-platanin, a plant immune defense activator of fungal origin.

ABSTRACT:

Background

The herbicide sector needs new modes of action and new ecofriendly molecules as active ingredients. In this study, we investigated the stimulation of the plant immune system as a strategy to reduce weed growth, a mechanism not exploited by any commercial herbicide. Plants possess an innate immune system able to detect pathogens' molecules such as cerato-platanin (CP), a fungal protein elicitor produced by Ceratocystis platani. As sensitivity of arable weeds to microbial elicitors is mostly unknown, the ability of CP to reduce germination and early seedling growth was examined in some Poaceae and Amaranthaceae by using wheat as an off-target species.

Results

CP-treated seeds from Lolium multiflorum, Digitaria sanguinalis and Amaranthus hybridus resulted in stunted
