Phloem sap intricacy and interplay with aphid feeding.
Aphididae feed upon the plant sieve elements (SE), where they ingest sugars, nitrogen compounds and other nutrients. For ingestion, aphid stylets penetrate SE, and because of the high hydrostatic pressure in SE, phloem sap exudes out into the stylets. Severing stylets to sample phloem exudates (i.e. stylectomy) has been used extensively for the study of phloem contents. Alternative sampling tec...
متن کاملPlant Defence Proteins during Aphid Infestation
Parasitism by phloem-feeding insects, such as aphids and whiteflies, are widespread and often serious constraint on plant growth. Aphids successfully exploit a broad range of vascular plants. Despite the ubiquity of phloem feeding insects, in depth knowledge of plant defence and plantmicrobe interactions is still lagging. This review summarizes the current knowledge about the phloem sap protein...
متن کاملWhich injuries may indicate child abuse?
Making the decision as to whether an injury is a result of child abuse or not is stressful for both the family involved and the clinical team. It is not a decision that is taken lightly, and with an increasing expectation by the investigating agencies, lawyers and the public in general, to ensure that it is based on explicit 'evidence', clinicians need to be up to date with the latest scientifi...
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...
متن کاملAdaptation of aphid stylectomy for analyses of proteins and mRNAs in barley phloem sap
Sieve tubes are transport conduits not only for photoassimilates but also for macromolecules and other compounds that are involved in sieve tube maintenance and systemic signalling. In order to gain sufficient amounts of pure phloem exudates from barley plants for analyses of the protein and mRNA composition, a previously described stylectomy set-up was optimized. Aphids were placed in sealed c...
