Myzus persicae Sulzer aphid contains oxylipins that
Oxylipins are oxygenated fatty acids and their derivatives that play key roles in response to stress. They are widespread in many organisms including mammals or plants but are unknown in arthropods. In this study, we identified oxylipins in Myzys persicae Sulzer aphids reared on Vicia faba L. plants. Further experiments based on: (i) Radiolabelled substrate incubation with aphid extracts, and (...
متن کاملA Functional Genomics Approach Identifies Candidate Effectors from the Aphid Species Myzus persicae (Green Peach Aphid)
Aphids are amongst the most devastating sap-feeding insects of plants. Like most plant parasites, aphids require intimate associations with their host plants to gain access to nutrients. Aphid feeding induces responses such as clogging of phloem sieve elements and callose formation, which are suppressed by unknown molecules, probably proteins, in aphid saliva. Therefore, it is likely that aphid...
متن کاملEffects of Lecanicillium longisporum infection on the behaviour of the green peach aphid Myzus persicae.
The effects of the entomopathogenic fungus Lecanicillium longisporum (Zimmerman) Zare & Gams on three parameters of behaviour (feeding, reproduction and movement) of the green peach aphid Myzus persicae (Homoptera: Aphididae) were investigated in the laboratory. Visual analysis of video tapes established that honeydew excretion events of mycosed aphids gradually declined from 2 d post inoculati...
متن کاملProbiotic effects of beta-glucuronidase on the peach-potato aphid Myzus persicae (Aphididae).
beta-glucuronidase (GUS) is a reporter protein commonly expressed in transgenic plants allowing the visualization of the transformed individuals. In our recent work, we showed that consumption of transformed potato plants expressing this GUS enzyme improves performance of the phloem feeding aphid Myzus persicae. Those results led us to the conclusion that the expression of GUS in potato plants ...
متن کاملArabidopsis thaliana—Myzus persicae interaction: shaping the understanding of plant defense against phloem-feeding aphids
The phloem provides a unique niche for several organisms. Aphids are a large group of Hemipteran insects that utilize stylets present in their mouthparts to pierce sieve elements and drink large volumes of phloem sap. In addition, many aphids also vector viral diseases. Myzus persicae, commonly known as the green peach aphid (GPA), is an important pest of a large variety of plants that includes...
