Project description:Different wheat cultivars may be classified as either winter or spring varieties depending on whether they require exposure to an extended period of cold in order to become competent to flower. Using a growth regime that mimics the conditions that occur during a typical winter in Britain, we wished to survey the genes that are involved in phase transition as well as those involved in cold-acclimation.

Project description:This dataset is associated with two publications 1. Elucidating the biochemical basis of trans-16:1 fatty acid change in leaves during cold acclimation in wheat. http://doi.org/10.1002/pei3.10044 In this study, comparative RNA-seq analyses with leaf tissues undergoing cold acclimation reveal concerted transcriptome shifts indicating a reduced chloroplast lipid pathway activity and increased cytosolic ER membrane lipid synthesis. To explore the underlying metabolic and transcriptional mechanisms responsible for the reduction of the t16:1 under cold, a detailed lipid analysis and comparative transcriptome study were conducted with four wheat cultivars during cold treatment. The RNA-seq dataset includes four wheat cultivars (Manitou, Winter Manitou, Norstar and Spring Norstar) treated with cold paired with control. The data as a whole show that leaf tissues experience a gradual decrease in chloroplast lipid pathway activity and the variation in the decline of chloroplast lipid synthesis in different cultivars manifest in the rate of decrease in t16:1decrease in leaf tissues. Future efforts are required to determine if and how the down regulation of the chloroplast lipid pathway is related to the development of winter hardiness. 2. Computational genomics insights into cold acclimation in wheat. https://doi.org/10.3389/fgene.2022.1015673 In this study, integrated computational approaches was employed to investigate the transcriptomics and lipidomics data associated with cold acclimation and vernalization in the four wheat genotypes of distinct cold tolerance. Differential expression was investigated between cold treated and control samples and between the winter-habit and spring-habit wheat genotypes. Collectively, 12,676 differentially expressed genes (DEGs) were identified. Principal component analysis of these DEGs indicated that the first, second, and third principal components (PC1, PC2, and PC3) explained the variance in cold treatment, vernalization and cold hardiness, respectively. Differential expression feature extraction (DEFE) analysis revealed that the winter-habit wheat genotype Norstar had high number of unique DEGs (1884 up and 672 down) and 63 winter-habit genes, which were clearly distinctive from the 64 spring-habit genes based on PC1, PC2 and PC3. Correlation analysis revealed 64 cold hardy genes and 39 anti-hardy genes. Cold acclimation encompasses a wide spectrum of biological processes and the involved genes work cohesively as revealed through network propagation and collective association strength of local subnetworks. Integration of transcriptome and lipidomics data revealed that the winter-habit genes, such as COR413-TM1, CIPKs and MYB20, together with the phosphatidylglycerol lipids, PG(34:3) and PG(36:6), played a pivotal role in cold acclimation and coordinated cohesively associated subnetworks to confer cold tolerance.

Project description:24-hour cold shock treatment applied to winter wheat T. monococcum ssp. aegilopoides (accession G3116) and the domesticated spring wheat T. monococcum ssp. monococcum (accession DV92). Tissues were harvested and homogenized using liquid nitrogen. RNA extraction was conducted using a modified chloroform extraction protocol (Plant Purification Reagent) followed by RNeasy Plant Mini Kit (50) for purification. Samples included: three G3116 control, three G3116 cold shock, three DV92 control, and three DV92 cold shock. Illumina samples were prepped using TruSeq RNA prep kit v.2 and sequenced on the Illumina Hiseq 2500 sequencing platform.

Project description:Sorghum (Sorghum bicolor L. Moench) is a C4 species sensitive to the cold spring conditions that occur at northern latitudes, usually coupled with excessive light, and that greatly affects the photosynthetic rate. The objective of this study was to discover genes/genomic regions that control the capacity to cope with excessive energy under low temperature conditions during the vegetative growth period. A genome-wide association study (GWAS) was conducted for eight photosynthesis and chlorophyll fluorescence traits under three consecutive temperature treatments: control (28°C/24°C), cold (15°C/15°C) and recovery (28°C/24°C). Cold stress significantly reduced the photosynthetic capacity of sorghum plants and a total of 204 genomic regions were discovered associated with at least one trait in a particular treatment or in the time integrated response to cold. If no GBS markers were available for the targeted candidate genes, new SNPs were developed and genotyped using a SNPtype™ Assay (Fluidigm) on the Fluidigm BioMarkHD system and GT 96.96 Dynamic Array Integrated Fluidic Circuits of Fluidigm.

Project description:The effect of light during the development of freezing tolerance was studied in winter wheat (Triticum aestivum L. var. Mv Emese) and spring wheat variety Nadro. Ten-day-old plants were cold hardened at 5°C for 12 days either under normal (250 mmol m-2 s-1) or low light (20 mmol m-2 s-1) conditions.

Project description:MicroRNAs (miRNAs) are single strand small non-coding RNAs that regulate target mRNAs at post-transcription level. Winter wheat (Triticum aestivum L.), is an important crop plant all over the world. Long term cold exposure (vernalization) is necessary for winter wheat transition from vegetative growth to reproductive growth, yet the involvement of miRNAs in these stages remains unknown. Therefore, we performed next generation sequencing of small RNAs profiles in crown tissues at three-leaf stage, winter dormancy stage, spring greenup stage and jointing stage.
