“…Compatible interactions, in contrast, are defined as those in which larvae are able to feed and develop normally on plants. These interactions, between virulent Hessian fly larvae and susceptible wheat plants, produce a variety of physiological changes in host plants including alterations in protein profiles (Shukle et al, 1992), amino acid content (Saltzmann et al, 2008), chlorophyll content (Robinson et al, 1960), and sugar content (Refai et al, 1955). As well, morphological changes occur in host plants experiencing compatible interactions.…”

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

et al. 2010

SUMMARYInfestation 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. Staining assays revealed that susceptible plants exhibited a generalized increase in leaf sheath epidermal permeability during infestation; whereas, epidermal permeability was only minimally affected in resistant plants. Furthermore, temporal profiling using gas chromatographic methods revealed that changes in cuticle lipid (wax and cutin) composition correlated well with differing levels of epidermal permeability in susceptible and resistant plants. Temporal analysis of cuticle-associated gene mRNA levels, by quantitative real-time PCR, indicated a relationship between transcript abundance and changes in cuticle lipid profiles of resistant and susceptible plants. Results suggest that conserving cuticle integrity via induction of specific wax constituents and maintenance of cutin amounts, determined by the accumulation of cuticle-associated transcripts, could be important components of wheat resistance to Hessian fly larvae.

“…Recognition of salivary gene products by susceptible plants does not trigger an effective defense. Instead, the physiology of susceptible plants changes, and they develop characteristic phenotypes of infestation, including a darkened green color due to chloroplast accumulation (Robinson et al, 1960), rapidly arrested growth, inability to set seed, and often seedling death (Cartwright et al, 1959).…”

H33: A Wheat Gene Providing Hessian Fly Resistance for the Southeastern United States

et al. 2014

Hessian fly populations adapt to overcome newly deployed resistance genes within a few years of release. Although more than 34 genes have been identified that confer resistance against Hessian fly [Mayetiola destructor (Say)] attack in wheat (Triticum aestivum L.), only five genes currently provide resistance against fly populations in the southeastern United States. But even these genes are not 100% effective, leaving Georgia and North and South Carolina with between one and three effective genes for cultivar development. With the goal of providing much needed resistance for this region in a wheat line suitable for use with marker‐assisted selection, we identified a durum wheat line that confers resistance to Hessian fly populations from Maryland, Delaware, North and South Carolina, and Georgia in 100% of the plants tested. Resistance from this tetraploid durum line, PI 134942, was introgressed into hexaploid common wheat to generate the line 97211. Segregating populations of F2:3 families were constructed with the durum donor and with the common wheat recipient to identify resistance genes and provide flanking markers. Although the resistance of the durum donor appeared to involve more than one gene, one partially dominant but very effective gene, H33, was successfully transferred and identified in the hexaploid recipient. This gene was mapped to the short arm of wheat chromosome 3A and is flanked by single sequence repeat markers xgwm218 and hbg284.

“…While the genetic basis of Hessian fly -wheat interactions has been intensively studied, very few cytological investigations have been undertaken. Robinson et al (1960) reported that the dark green color characteristic of infested plants resulted from increased numbers of chloroplasts in leaf cells. McMullen and Walgenbach (1986) examined infested plants by transmission electron microscopy and found disruption of cellular membranes and plastids in wheat infested with flies of unspecified biotype.…”

Hypersensitive response of wheat to the Hessian fly

Hessian fly Mayetiola destructor (Say) larvae are able to obtain food from their host plant without inflicting mechanical damage to the plant surface, apparently by secreting substances which elicit release of nutrients from plant cells surrounding the feeding site. Cells of fully susceptible plants retain their normal appearances, while in resistant plants extensive areas of cellular collapse occur. These responses indicate that hypersensitivity is the basis of wheat's resistance to the Hessian fly. The fly's feeding mechanism more closely resembles that of a pathogen than of a phytophagous insect; correspondingly, both the genetic relationship and resistance mechanism of the host plant to the parasite are of the sorts commonly associated with bacterial and fungal pathogens.
