Genome 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...
متن کاملDistribution and diversity of russian wheat aphid (Hemiptera: Aphididae) biotypes in North America.
Wheat, Triticum aestivum L., with Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae) resistance based on the Dn4 gene has been important in managing Russian wheat aphid since 1994. Recently, five biotypes (RWA1-RWA5) of this aphid have been described based on their ability to differentially damage RWA resistance genes in wheat. RWA2, RWA4, and RWA5 are of great concern beca...
متن کاملInterstitial cystitis: an unsolved enigma.
Painful bladder syndrome/interstitial cystitis (PBS/IC) is a chronic disease of unknown etiology characterized by vague bladder pain and nonspecific urinary symptoms, such as urgency and frequency. Although it was initially considered to be a rare condition, its prevalence has significantly increased, possibly because of different definitions used and greater physician awareness. Because of the...
متن کاملGlycoproteins from Russian wheat aphid infested wheat induce defence responses.
Elicitors are molecules which can induce the activation of plant defence responses. Elicitor activity of intercellular wash fluid from Russian wheat aphid, Diuraphis noxia (Mordvilko) infested resistant (cv Tugela DN), and susceptible (cv Tugela), wheat (Triticum aestivum L.), was investigated. Known Russian wheat aphid resistance related responses such as peroxidase and beta-1,3-glucanase acti...
متن کاملPLANT RESISTANCE Limited Genetic Variation Within and Between Russian Wheat Aphid (Hemiptera: Aphididae) Biotypes in the United States
Insect biotypes are populations able to kill or injure crops with resistance genes and complicate pest management programs based on host plant resistance. Biotypes occur in Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), a worldwide pest of wheat, Triticum aestivum L., and barley, Hordeum vulgare L., that was introduced into Mexico in 1980 and then spread into Texas by ...
