Damage of brown planthopper (BPH) and rice leaf folder (LF) in parent plants lead to distinct resistance in ratoon rice.

Herbivore-induced defense responses are often specific, whereas plants could induce distinct defense responses corresponding to infestation by different herbivorous insects. Brown plant hopper (BPH) , a phloem-feeding insect, and rice leaf folder (LF) , a chewing insect, are both specialist herbivores on rice. To characterize the distinct resistance primed by prior damage to these two specialist herbivores, we challenged rice plants with two herbivores during vegetative growth of parent plants and assessed plant resistance in subsequent ratoons.

Seed priming with calcium chloride enhances wheat resistance against wheat aphid Schizaphis graminum Rondani.

Background: Calcium is an essential macronutrient for plant growth. Although it has been shown that exogenous Ca application can increase plant resistance to abiotic stress, little is known about its potential to enhance plant tolerance to biotic stress. Here, we investigated whether pretreatment of wheat (Triticum aestivum L.
