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

  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 ...

    BMC Genomics 14:187 (2013) PMID 23496979 PMCID PMC3608969

    MicroRNAs (miRNAs) are small non-coding RNAs that play critical roles in regulating post transcriptional gene expression. Gall midges encompass a large group of insects that are of economic importance and also possess fascinating biological traits. The gall midge Mayetiola destructor, commonly k...

  8. Obviation of wheat resistance to the Hessian fly through systemic induced susceptibility.

    Journal of Economic Entomology 105(2):642 (2012) PMID 22606837

    Unlike most documented plant-insect interactions, Hessian fly-resistance [Mayetiola destructor (Say)] in wheat (Triticum aestivum L.) is initiated by a gene-for-gene recognition event in which plants carrying a specific R gene recognize salivary effectors encoded by a corresponding larval avirul...

  10. 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...

  12. 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...

  14. Changes in properties of wheat leaf cuticle during interactions with Hessian fly.

    Plant Journal 63(1):31 (2010) PMID 20409001

    Infestation of wheat by Hessian fly larvae causes a variety of physical and biochemical modifications of the host plant. Changes occur in cuticle permeability, lipid composition and gene transcript abundance, and these responses differ substantially between resistant and susceptible wheat lines....
  15. 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 ...
