Project description:Wheat streak mosaic virus (WSMV) and Triticum mosaic virus (TriMV) are type members of Tritimovirus and Poacevirus genera, respectively, in the family Potyviridae, and are transmitted by wheat curl mites. Co-infection of these two viruses causes synergistic interaction with increased virus accumulation and disease severity in wheat. In this study, we examined the effects of synergistic interaction between WSMV and TriMV on endogenous small (s) RNAs and virus-specific small interfering RNAs (vsiRNAs) in susceptible (Arapahoe) and temperature-sensitive resistant (Mace) wheat cultivars at 27ºC and 18ºC. Single- and double-infections in wheat caused a shift in the profile of endogenous sRNAs from 24 nt being the most predominant in healthy plants to 21 nt in infected wheat. Additionally, we report high-resolution vsiRNA maps of WSMV and TriMV in singly- and doubly-infected wheat cultivars Arapahoe and Mace at 18ºC and 27ºC. Massive amounts of 21 and 22 nt vsiRNA reads were accumulated in Arapahoe at both temperatures and in Mace at 27ºC but not at 18ºC. The plus- and minus-sense vsiRNAs were distributed throughout the genomic RNAs in Arapahoe at both temperature regimens and in Mace at 27ºC, although some regions of genomic RNAs serve as hot-spots with an excessive number of vsiRNAs. The positions of vsiRNA peaks were conserved among wheat cultivars Arapahoe and Mace, suggesting that Dicer-like enzymes of susceptible and resistant wheat cultivars are similarly accessed the genomic RNAs of WSMV and TriMV. Additionally, several cold-spot regions were found in the genomes of TriMV and WSMV with no or a few vsiRNAs, indicating that certain regions of WSMV and TriMV genomes are not accessible to Dicer-like enzymes. The high-resolution map of endogenous and vsiRNAs from wheat cultivars synergistically infected with WSMV and TriMV at two temperature regimens form a foundation for understanding the virus-host interactions, effect of synergistic interactions on host defense mechanisms, and virus resistance mechanisms in wheat.

Project description:In this study, we used dual RNA-sequencing to profile FHB-resistant AC Emerson, FHB-moderately AC Morley, and FHB-susceptible CDC Falcon winter wheat cultivars prior to and in response to Fusarium graminearum at 7 days post inoculation. Differential expression analyses revealed distinct defense responses between resistant and susceptible wheat cultivars including increased mechanical defense through lignin biosynthesis and increased deoxynivalenol (DON) detoxification through UDP-glycosyltransferase activity in resistant cultivars. Further, differential expression analysis in F. graminearum challenging these distinct cultivars revealed changes genes involved in trichothecene mycotoxin biosynthesis.

Small RNA was sequenced from two wheat cultivars (Mace and Araphahoe), at two temperatures 18C and 27C, for healthy (control/uninfected), infected with wheat streak mosaic virus (WSMV), infected with Triticum mosaic virus (TriMV), and a double-infecttion of WSMV and TriMV.

Project description:The economic importance of wheat and its contribution to human and livestock diets has been already demonstrated. However, wheat production is impacted by pests that induce yield reductions. Among these pests, wheat curl mite (WCM, Aceria tosichella Keifer) impacts wheat all around the world. WCM are tiny pests that feed within the whorl of developing leaves and prevent the leaves from unfurling by causing leaves curling. The curling of the leaves provides a protective niche for the WCM. Additionally, WCM are also the vector of serious viruses in wheat. Little is known regarding the impact of the WCM on wheat transcriptome, and to date, only one article has been published describing the wheat transcriptomic changes after 1 day of WCM feeding. To better understand the wheat transcriptome variation after long-term feeding by WCM (10 days post infestation (dpi)), we used an RNA-seq approach. We collected leaves uninfested and infested with WCR from two wheat cultivars: Byrd (WCM resistant) and Settler CL (WCM susceptible) at 10 dpi. Our transcriptomic analysis revealed the common and specific transcriptomic variations in WCM resistant and susceptible wheat cultivars, chromosome specific location of the differentially expressed genes, and also identified the gene functions and pathways involved in WCM resistance. Collectively, our study provides important insights on wheat defense mechanisms against WCM after long-term feeding.

Project description:Wheat is a cereal grain and one of the world’s major food crops. Recent advances in wheat genome sequencing are by now facilitating genomic and proteomic analyses of this crop. However, little is known about the protein levels of hexaploid versus tetraploid wheat cultivars, and knowledge on phosphorylated proteins still limited. Using our recently established (phospho)proteomic workflow, we performed a parallel analysis of the proteome and phosphoproteome on seedling leaves from two hexaploid wheat cultivars (Pavon 76 and USU-Apogee) and a tetraploid wheat (Senatore Cappelli). This revealed that a large portion of proteins and phosphosites can be quantified in all cultivars. Our shotgun proteomics data revealed a high similarity between hexaploid and tetraploid varieties with respect to protein abundance. However, we could identify a set of proteins that were differentially abundant between hexaploid and tetraploid cultivars. In addition, already at seedling stage, a small set of proteins were differential between the small (USU-Apogee) and larger hexaploid wheat cultivar (Pavon 76), which could potentially act as growth predictors. Finally, the phosphosites identified in this study can be retrieved from the in-house developed plant PTM-Viewer (bioinformatics.psb.ugent.be/webtools/ptm_viewer/), making this the first repository for phosphorylated wheat proteins. This paves the way for further in depth, quantitative (phospho)proteome-wide differential analyses upon a specific trigger or environmental change.

Project description:Water deficit stress between the booting and grain filling stages significantly affect grain yield and quality of hard red winter wheat. Several stress tolerant cultivars with different adaptation mechanisms have been released and are widely cultivated on the Southern Great Plains of the US. However, the physiological, molecular, and genetic basis of adaptation to drought stress for these cultivars remains unknown. Use of transcriptome profiling to identify drought responsive genes in hexaploid wheat is a challenging process given the quantitative nature of drought stress, genome complexity, and the intricacy of interaction effects. If the information generated from functional genomics studies is to be used in molecular breeding programs for cultivar development, it is highly desirable to use cultivars better adapted for the region. In the current study we used two well-adapted, drought-tolerant, high-yielding, cultivated varieties, TAM 111 and TAM 112, which appear to have different adaptation mechanisms, to identify drought stress induced transcripts during heading and early dough stages. A set of 24 Affymetrix GeneChip wheat genome arrays (2 cultivars; 2 water treatments; 2 sampling stages; 3 biological replicates) from plants subjected to water deficit stress under controlled glasshouse conditions. Differentially expressed genes were identified using a ANOVA (p<0.01) controlling false discovery rate (FDR, q<0.01) using Benjamini Hochberg approach.
