Project description:The study was conducted in order to find out the differential change in the transcript of tolerant and susceptible wheat cultivar under heat stress and to decipher the mechanism of thermotolerance in wheat by identifying novel genes and transcription factors involved in the pathways. Wheat cultivar HD2985 (thermotolerant) and HD2329 (thermosusceptible) were exposed to heat stress of 42 degree for 4h at pollination stage and samples were collected from both control and heat shock treated plants for further characterization.

Project description:The aim of this study was to identify genetic mechanisms of tolerance to active de-acclimation in winter wheat by comparing four tolerant and four susceptible accessions (cultivars and advanced breeding lines). The plants were kept in controlled conditions. 21 days after sowing, the plants were cold acclimated (3 weeks, 4/2 °C, day/night temperature; photoperiod of 10/14 h). Cold acclimation was followed by 7 days of de-acclimating conditions, mimicking a mid-winter warm spell: 12/5°C, day/night temperature; photoperiod of 10/14 h). The fragments of leaves were sampled in three biological replicates (three different plants of the same accession) in three timepoints: just before cold-acclimation (CA-0), after cold-acclimation (CA-21), and after de-acclimation (DA-28). Total RNA samples were sequenced on Illumina NovaSeq 6000 platform in PE150 bp mode. Differences in expression for a given accession were tested between all time-points, averaging the results for three biological replicates. It has been confirmed that active de-acclimation is not simply the inverse of cold acclimation, and that susceptible forms show significantly more changes in expression as a result of de-acclimation than tolerant forms. This provides further support for the hypothesis that tolerance to de-acclimation consists mainly of the absence or weakest response to temperature rise. Among the genes whose expression was significantly altered as a result of de-acclimation, a significant group were genes related to the defence response to stress. In wheat particularly plant hormone related genes, and plant hormones, seem to be playing a crucial role in the response to active de-acclimation, especially ABA and SA. Our results also suggest that in wheat the period of cold-acclimation might be decisive in the later active de-acclimation tolerance.

Project description:Agrobacterium-mediated plant transformation is an extremely complex and evolved process involving genetic determinants of both the bacteria and the host plant cells. However, the mechanism of the determinants remains obscure, especially in some cereal crops such as wheat, which is recalcitrant for Agrobacterium-mediated transformation. In this study, differentially expressed genes (DEGs) were analyzed in wheat callus cells co-cultured with Agrobacterium by using RNA sequencing (RNA-seq). Note: All samples in SRA were assigned the same sample accession (SRS417803). This is incorrect as there are different samples, hence “Source Name” was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Project description:The pistillody mutant wheat (Triticum aestivum L.) plant HTS-1 exhibits homeotic transformation of stamens into pistils or pistil-like structures. Unlike common wheat varieties, HTS-1 produces three to six pistils per floret, potentially increasing the yield. Thus, HTS-1 is highly valuable in the study of floral development in wheat. In this study, we conducted RNA sequencing of the transcriptomes of the pistillody stamen (PS) and the pistil (P) from HTS-1 plants, and the stamen (S) from the non-pistillody control variety Chinese Spring TP to gain insights into pistil and stamen development in wheat.

Project description:To better understand the regulatory mechanisms of water stress response in wheat, the transcript profiles in roots of two wheat genotypes, namely, drought tolerant 'Luohan No.2' (LH) and drought susceptible 'Chinese Spring' (CS) under water-stress were comparatively analyzed by using the Affymetrix wheat GeneChip®. A total of 3831 transcripts displayed 2-fold or more expression changes, 1593 transcripts were induced compared with 2238 transcripts were repressed, in LH under water-stress; Relatively fewer transcripts were drought responsive in CS, 1404 transcripts were induced and 1493 were repressed. Comparatively, 569 transcripts were commonly induced and 424 transcripts commonly repressed in LH and CS under water-stress. 689 transcripts (757 probe sets) identified from LH and 537 transcripts (575 probe sets) from CS were annotated and classified into 10 functional categories, and 74 transcripts derived from 80 probe sets displayed the change ratios no less than 16 in LH or CS. Several kinds of candidate genes were differentially expressed between the LH and CS, which could be responsible for the difference in drought tolerance of the two genotypes.

Project description:We aimed to test the hypothesis that the transcriptional profile of wheat roots can be changed by the AM symbiotic signals, even though there is no physical contact with AM fungi. A total of 2,360 differentially expressed genes (DEGs), including 1,888 up-regulated DEGs and 472 down-regulated DEGs were found. Among them, 59 were highly induced DEGs (gene expression fold changed > 500), and 121 genes only expressed in the NM treatment. The DGEs covered all the 21 chromosomes of wheat genome, and were dominantly distributed on the 2A, 2B, 2D, 3B, 5B and 5D chromosomes. Most of the DEGs located at membrane, and functioned in catalytic activity, transferase activity and binding. 63 orthologues of the previously reported genes wich play important roles during AM symbiosis in model plants were found.
