Mechanisms and evolution of plant resistance to aphids
2016年1月6日 · Compared to chewing herbivores, aphid feeding typically causes relatively little harm to a plant. Furthermore, aphids produce and inject specific compounds (‘effectors’) intended to modulate...
Performances of survival, feeding behavior and gene expression in ...
2016年1月13日 · Aphids feed on the phloem sap of host plants through stylet penetration, during which saliva is secreted from the aphid salivary gland, delivering effector proteins to overcome plant defenses...
Phytohormonal signaling in plant responses to aphid feeding
2011年4月8日 · Aphid feeding induces various defense signaling mechanisms in plants. The recognition of feeding activities by plants occurs through the use of transmembrane pattern recognition receptors (PRRS) or, acting largely inside the cell, polymorphic nucleotide-binding leucine-rich-repeat (NB-LRR) protein products, encoded by most R genes.
Location, location, location: Feeding site affects aphid ... - PLOS
2021年2月4日 · In this study, we determined the feeding behavior and performance of soybean aphids (Aphis glycines) on the stem, the adaxial (upper), and the abaxial (lower) leaf surfaces during early vegetative growth of soybean plants.
THE MOUTHPARTS AND FEEDING MECHANISM OF APHIDS
1977年1月1日 · The aphid's method of feeding is the principal reason why they are such a successful group and are such important pests to agriculture. The mouthparts of the aphids are perfectly adapted for piercing plant tissue and extracting sap for food, and they are also the direct means of acquisition and transmission of plant viruses.
Aphids: Current Biology - Cell Press
2008年6月24日 · Aphids are small, soft-bodied insects that feed by inserting their slender mouthparts into phloem cells, the food conduits of plants. Most aphid species feed on only one species of plant and closely related aphid species tend to …
Location, location, location: Feeding site affects aphid …
2021年2月4日 · In this study, we determined the feeding behavior and performance of soybean aphids ( Aphis glycines) on the stem, the adaxial (upper), and the abaxial (lower) leaf surfaces during early vegetative growth of soybean plants.
Molecular responses to aphid feeding in Arabidopsis in relation …
Aphid feeding induced 10-fold increases in mRNA levels of a stress-related monosaccharide symporter gene, STP4. Phloem feeding on Arabidopsis leads to stimulation of response pathways associated with both pathogen infection and wounding.
Aphid feeding induces the relaxation of epigenetic control and …
2021年1月21日 · Our results demonstrate that aphid feeding induces loss of methylation of hundreds of loci, mainly TEs. This loss of methylation has the potential to regulate gene expression and we found evidence that it is involved in the control of plant immunity genes.
Effects of host plants on aphid feeding behavior, fitness, and
2024年8月8日 · Aphids are sap-feeding plant pests that depend on their symbiotic relationships with the primary endosymbiont Buchnera aphidicola to adapt to impoverished diets. However, how the host plant affects the aphid primary symbiont and …
