1. A Massive Expansion of Effector Genes Underlies Gall-Formation in the Wheat Pest Mayetiola destructor.

    Current Biology 25(5):613 (2015) PMID 25660540

    Gall-forming arthropods are highly specialized herbivores that, in combination with their hosts, produce extended phenotypes with unique morphologies [1]. Many are economically important, and others have improved our understanding of ecology and adaptive radiation [2]. However, the mechanisms th...
  2. Hessian fly larval feeding triggers enhanced polyamine levels in susceptible but not resistant wheat.

    BMC Plant Biology 15:3 (2015) PMID 25592131 PMCID PMC4308891

    Hessian fly (Mayetiola destructor), a member of the gall midge family, is one of the most destructive pests of wheat (Triticum aestivum) worldwide. Probing of wheat plants by the larvae results in either an incompatible (avirulent larvae, resistant plant) or a compatible (virulent larvae, suscep...

  4. A genome-wide survey of small interfering RNA and microRNA pathway genes in a galling insect.

    Journal of Insect Physiology 59(3):367 (2013) PMID 23232437

    Deployment of resistance (R) genes is the most effective control for Hessian fly, Mayetiola destructor (Say); however, deployment of R genes results in an increased frequency of pest genotypes that display virulence to them. RNA interference (RNAi) is a useful reverse genetics tool for studying ...

  6. Effects of antinutrient proteins on Hessian fly (Diptera: Cecidomyiidae) larvae.

    Journal of Insect Physiology 58(1):41 (2012) PMID 21983260

    One strategy to enhance the durability of Hessian fly resistance (R) genes in wheat is to combine them with transgenes for resistance. To identify potential transgenes for resistance a protocol for rapidly screening the proteins they encode for efficacy toward resistance is required. However, th...

  8. Induced epidermal permeability modulates resistance and susceptibility of wheat seedlings to herbivory by Hessian fly larvae.

    Journal of Experimental Botany 62(13):4521 (2011) PMID 21659664 PMCID PMC3170548

    Salivary secretions of neonate Hessian fly larvae initiate a two-way exchange of molecules with their wheat host. Changes in properties of the leaf surface allow larval effectors to enter the plant where they trigger plant processes leading to resistance and delivery of defence molecules, or sus...

  10. Virulence in Hessian fly (Diptera: Cecidomyiidae) field collections from the southeastern United States to 21 resistance genes in wheat.

    Journal of Economic Entomology 103(6):2229 (2010) PMID 21309248

    Genetic resistance in wheat, Triticum aestivum L., is the most efficacious method for control of Hessian fly, Mayetiola destructor (Say) (Diptera: Cecidomyiidae). However, because of the appearance of new genotypes (biotypes) in response to deployment of resistance, field collections of Hessian ...

  12. Ultrastructural changes in the midguts of Hessian fly larvae feeding on resistant wheat.

    Journal of Insect Physiology 56(7):754 (2010) PMID 20116382

    The focus of the present study was to compare ultrastructure in the midguts of larvae of the Hessian fly, Mayetiola destructor (Say), under different feeding regimens. Larvae were either fed on Hessian fly-resistant or -susceptible wheat, and each group was compared to starved larvae. Within 3h ...
  13. Unusual conservation among genes encoding small secreted salivary gland proteins from a gall midge.

    BMC Evolutionary Biology 10:296 (2010) PMID 20920202 PMCID PMC2955719

    In most protein-coding genes, greater sequence variation is observed in noncoding regions (introns and untranslated regions) than in coding regions due to selective constraints. During characterization of genes and transcripts encoding small secreted salivary gland proteins (SSSGPs) from the Hes...
