Differential gene expression in nearly isogenic lines with QTL for partial resistance to Puccinia hordei in barley

Abstract: BackgroundThe barley-Puccinia hordei (barley leaf rust) pathosystem is a model for investigating partial disease resistance in crop plants and genetic mapping of phenotypic resistance has identified several quantitative trait loci (QTL) for partial resistance. Reciprocal QTL-specific near-isogenic lines (QTL-NILs) have been developed that combine two QTL, Rphq2 and Rphq3, the largest effects detected in a recombinant-inbred-line (RIL) population derived from a cross between the super-susceptible line L94 and p… Show more

“…Among different defense-related enzymes, the role of chitinases in hypersensitive reactions during induced host resistance in tissues followed by pathogen infection was demonstrated by several research workers [5]. Chitin-mediated resistance has been proved against fungal diseases in various crops such as rice, grapevine, and peanut [6][7][8] and nematode infection in rice and tomato [9]. Similarly in the case of banana, more accumulation of endochitinases and putative chitinase transcripts, which are involved in fungal cell wall degradation, was reported in Mycosphaerella musicola-challenged leaves [10].…”

“…The transcriptome of rust-attacked barley has been analysed recently aiming at a general description of host changes as well as the identification of expression QTL (eQTL) loci for partial resistance (Chen et al 2010b;Moscou et al 2011b). Barley recognizes the presence of rust spores from approximately 12 h.a.i.…”

“…Barley recognizes the presence of rust spores from approximately 12 h.a.i. onwards, while fungal development is still confined to the leaf or stem surface, before penetration of stomata by appressoria, and responds with the differential regulation of a large number of transcripts (Chen et al 2010b;Zellerhoff et al 2010). Over all analysed time points (12-48 h.a.i.…”

“…Microarrays have been used in a study to assess differential expression in two barley cultivars (L94, susceptible, Vada, partially resistant) infected or uninfected with Puccinia hordei, with the identification of 802 fragments related to plant genes responsive to this fungus being present in inoculated plants but absent from uninoculated controls [37]. Of the genes detected, 584 were common to both cultivars, 34 were specific to L94, 24 were specific to Vada and 160 showed no homology to genes described in the literature and thus represented potential genes to be studied.…”

“…Microarrays enable the study of many genes simultaneously, in a semi-quantitative way, and have been widely used to address several biological, genetic and biochemical issues [37,58]. Normally this analysis is performed with previously known gene sequences inserted into an array.…”
