The response was visually similar to the hypersensitive cell death response, typical of resistance to microbial pathogens. Resistant barley produced signi...
متن کاملGenome of Russian wheat aphid an economically important cereal aphid
Although the hemipterans (Aphididae) are comprised of roughly 50,000 extant insect species, only four have sequenced genomes that are publically available, namely Acyrthosiphon pisum (pea aphid), Rhodnius prolixus (Kissing bug), Myzus persicae (Green peach aphid) and Diuraphis noxia (Russian wheat aphid). As a significant proportion of agricultural pests are phloem feeding aphids, it is crucial...
