Search Results for "Aphid Rearing Solanum Potato"
Original Source: Infestation of potato (Solanum tuberosum L.) by the peach-potato aphid (Myzus persicae Sulzer) alters cellular redox status and is influenced by ascorbate.
The peach-potato aphid (Myzus persicae Sulzer) is a major pest of potato (Solanum tuberosum L) but the molecular characterisation of this interaction particularly with regard to oxidants and antioxidants remains to be undertaken. Aphid colonies reared on potato leaves containing high ascorbate were twice the size of those grown on leaves with low ascorbate. Infestation-dependent decreases in the abundance of key transcripts such as chloroplastic FeSOD, peroxisomal catalase 2, PR1 and JAZ1 preceded detectabl...

The tomato genome sequence provides insights into fleshy fruit evolution
Tomato (Solanum lycopersicum) is a major crop plant and a model system for fruit development. Solanum is one of the largest angiosperm genera and includes annual and perennial plants from diverse habi...
Ants farm root aphid clones in subterranean rooms
(BioMed Central) New research published in BioMed Central's open-access journal BMC Evolutionary Biology shows that over half of ant mounds contained only one of the three most common species of aphi...
Naturally occurring allele diversity allows potato cultivation in northern latitudes
Potato (Solanum tuberosum L.) originates from the Andes and evolved short-day-dependent tuber formation as a vegetative propagation strategy. Here we describe the identification of a central regulator...

AMARILLO – Do potato psyllids migrate from one location to the next, starting in northern Mexico and moving northward as the potato season progresses, or are psyllid populations local? Knowing wheth...
Potato blight: Fungus did not cause potato famine
The agent responsible for the blight that caused the nineteenth-century Irish potato famine, Phytophthora infestans, should not be “grouped with fungi” (Nature493, 154–156; 201310.1038/493154a)....

Changes in aphid probing behaviour as a function of insect age and plant resistance level.
Aphids perform a series of behaviours to assess feeding suitability and, hence, to select a plant. Little information, however, is available on such behaviour after aphids have settled on a plant. Obs...
