Microarray analysis of the interaction between the aphid Rhopalosiphum padi and host plants reveals both differences and similarities between susceptible and partially resistant barley lines
TL;DR: Microarray analysis of gene expression after aphid infestation in two susceptible and two partially resistant barley genotypes revealed large differences in gene induction between the four lines, indicating substantial variation in response even between closely related genotypes.
Journal ArticleDOI
Stronger induction of callose deposition in barley by Russian wheat aphid than bird cherry-oat aphid is not associated with differences in callose synthase or β-1,3- glucanase transcript abundance.

TL;DR: The results suggest that callose accumulation may be partly responsible for the symptoms resulting from RWA infestation and that a callose-inducing signal may be transported in the phloem.
Journal ArticleDOI
N-Methyltransferase Involved in Gramine Biosynthesis in Barley: Cloning and Characterization
TL;DR: A clear relationship was shown between the presence of the MT gene, the MT protein and N-methyltransferase activity, and the identification of the gene as coding for an N- methyltransferase (NMT) and being involved in gramine biosynthesis.
Journal ArticleDOI
Infection with an insect virus affects olfactory behaviour and interactions with host plant and natural enemies in an aphid
TL;DR: Infection with Rhopalosiphum padi virus reduced the lifespan and population growth rate of the aphid and infected aphids were more behaviourally sensitive to aphid alarm pheromone, and left the host plant more readily in response to it.
Journal ArticleDOI
An improved detection method for the Rhopalosiphum padi virus (RhPV) allows monitoring of its presence in aphids and movement within plants.
TL;DR: Testing of R. padi aphids collected from different sites in Sweden revealed the presence of RhPV in wild aphid populations for the first time in Europe, and systemic transport of the virus in plants was tracked.
