Abstract
Insect vector-borne diseases are a major constraint to a wide variety of crops. Plants integrate environmental light and internal signalings to defend dual stresses both from the vector insects and vector-transmitted pathogens. In this review, we highlight a studies that demonstrate how light regulates plants deploying mechanisms against vector-borne diseases. Four major host defensive pathways involved in the host defense network against multiple biotic stresses are reviewed: innate immunity, phytohormone signaling, RNA interference, and protein degradation. The potential with light-engineering technology with light emitting diodes (LEDs) and genome engineering technology for fine-tuning crop defense and yield are also discussed.
Highlights
Global warming has driven the emergence and reemergence of insect vector-borne plant diseases soaring and causes a huge loss in agricultural production
We focus on the effects of supplemental light emitting diodes (LEDs) light of specific wavelengths, we note that similar results may be obtained with other artificial light sources that provide specific wavelengths
Zhao et al (2021) found that red light promoted the mutualism of whitefly-begomovirus by stabilizing βC1 protein encoded by tomato yellow leaf curl China virus (TYLCCNV)-associated betasatellite and accumulated βC1 further inhibits phytochrome-interacting factors (PIFs) positively controlling of plant defenses against whitefly by reducing the promoter-binding activity of PIFs to terpene synthase (TPS) genes
Summary
Global warming has driven the emergence and reemergence of insect vector-borne plant diseases soaring and causes a huge loss in agricultural production. These studies unrevealed the resistance regulated functions of essential factors in light signaling, which provides a significant insight into the further exploration of light signaling-mediated plant defense against insect-borne pathogens. These TFs regulate plant defense responses to pathogens and herbivores by activating the resistance genes expression.
