Comparative Hessian Fly Larval Transcriptomics Provides Novel Insight into Host and Nonhost Resistance

Abstract: The Hessian fly is a destructive pest of wheat. Employing additional molecular strategies can complement wheat’s native insect resistance. However, this requires functional characterization of Hessian-fly-responsive genes, which is challenging because of wheat genome complexity. The diploid Brachypodium distachyon (Bd) exhibits nonhost resistance to Hessian fly and displays phenotypic/molecular responses intermediate between resistant and susceptible host wheat, offering a surrogate genome for gene characteriz… Show more

“…During incompatible interactions, the resistant plants mount defense responses (Liu et al., 2007; Sardesai et al., 2005; Subramanyam et al., 2006, 2008, 2013) that prevent the avirulent larvae from feeding, leading to their death within 4–5 days after egg hatch (DAH), and the wheat seedlings show normal growth (Gallun, 1977). In contrast, during compatible interactions, the larval salivary secretions suppress the plant immune response and alter host plant physiology, resulting in development of a nutritive tissue that is a source of diet rich in proteins and sugars, allowing the virulent larvae to complete their development, whereas the growth of the susceptible plants is stunted (Harris et al., 2006; Puthoff et al., 2005; Subramanyam & Nemacheck, 2021b; Subramanyam et al., 2015, 2018, 2021; Williams et al., 2011).…”
