Transcriptome analysis reveals key differentially expressed genes involved in wheat grain development.

ABSTRACT: Wheat seed development is a very important stage in the cereal crops seed life cycle. The accumulation reserves of wheat mature seeds provide not only the food for human and livestock feed, but also the energy for the seed germination.However, due to the large genome size, many studies related to wheat seed are very complex and uncompleted. Transcriptome analysis of elite Chinses bread wheat cultivar Jimai 20 may provides a comprehensive understanding of wheat seed development. Seed development involves in the regulation of large number of genes, whether these genes are normal activated or not is very important to seed development. We performed microarray analysis using the Affymetrix Gene Chip to reveal the gene expression profiles in the phases of wheat cultivar Jimai 20 grain filling. Our results provide a new insights into the thoroughly metabolic changes of seed development as well as the key differentially expressed genes involved in wheat grain development.

Transcriptome analysis during seed germination of elite Chinese bread wheat cultivar Jimai 20

Project description:Wheat seed germination is highly related to seedling survival rate and subsequent vegetative growth,and therefore directly affects the conformation of wheat yield and quality. So wheat seed germination is not only important to itself, but the whole human society. However, due to the large genome size, many studies related to wheat seed are very complex and uncompleted. Transcriptome analysis of elite Chinese bread wheat cultivar Jimai 20 may provides a comprehensive understanding of wheat seed germination. Seed germination involves in the regulation of large number of genes, whether these genes are normal activated or not is very important to seed germination. We performed microarray analysis using the Affymetrix Gene Chip to reveal the gene expression profiles in five phases of wheat cultivar Jimai 20 seed germination. Our results provide a new insights into the thoroughly metabolic changes of seed germination as well as the relationship between some significant genes.

Comparative transcriptome analysis of wheat embryo and endosperm response to ABA and H2O2 stresses during seed germination

Project description:Wheat seed germination directly affects wheat yield and quality. The wheat grains mainly include embryo and endosperm, and both play important roles in seed germination, seedling survival and subsequent vegetative growth. ABA can positively regulate dormancy induction and then negatively regulates seed germination at low concentrations. H2O2 treatment with low concentration can promote seed germination of cereal plants. Although various transcriptomics and proteomics approaches have been used to investigate the seed germination mechanisms and response to various abiotic stresses in different plant species, an integrative transcriptome analysis of wheat embryo and endosperm response to ABA and H2O2 stresses has not reported so far. We used the elite Chinese bread wheat cultivar Zhenmai 9023 as material and performed the first comparative transcriptome microarray analysis between embryo and endosperm response to ABA and H2O2 treatments during seed germination using the GeneChip® Wheat Genome Array Wheat seed germination includes a great amount of regulated genes which belong to many functional groups. ABA/H2O2 can repress/promote seed germination through coordinated regulating related genes expression. Our results provide new insights into the transcriptional regulation mechanisms of embryo and endosperm response to ABA and H2O2 treatments during seed germination

Genome interplay in the grain transcriptome of hexaploid bread wheat

Project description:Allohexaploid bread wheat (Triticum aestivum, L.) provides ~ 20% of calories consumed by humans. Hitherto lack of genome sequence for the three homoelogous and highly similar bread wheat genomes (A, B and, D) impeded expression analysis of the grain transcriptome. We used novel genome information to analyze the cell type specific expression of homeologous genes in the developing wheat grain.

Transient drought during flowering initiation modifies the grain proteome of bread winter wheat

Project description:Drought is among the most limiting factors for sustainable agricultural production. Water shortage at the onset of flowering severely affects the quality and quantity of grain yield of bread wheat (Triticum aestivum). Herein, we measured oxidative stress and photosynthesis-related parameters upon applying transient drought on contrasting wheat cultivars at the flowering initiation stage of ontogenesis. The sensitive cultivar showed ineffective water management and a more severe decline of photosynthesis. Apparently, the tolerant genotype used photorespiration to dissipate excessive light energy. The tolerant cultivar sooner induced superoxide dismutase and showed less inhibited photosynthesis. Such protective effect resulted in less affected yield and spectrum of seed proteome. The tolerant cultivar had a more stable gluten profile, which defines bread-making quality, upon drought. Drought caused the accumulation of medically relevant proteins: (i) components of gluten in the sensitive cultivar and (ii) metabolic proteins in the tolerant cultivar. We propose specific proteins as markers of drought tolerance for guiding efficient breeding: thaumatin-like protein, 14-3-3 protein, peroxiredoxins, peroxidase, FBD domain protein, and Ap2/ERF plus B3 domain protein.

Wheat leaf phosphoproteome under drought stress

Project description:Waxy starch has an important influence on the qualities of breads. Generally, grain weight and yield in waxy wheat (Triticum aestivum L.) are significantly lower than in bread wheat. In this study, we performed the first proteomic and phosphoproteomic analyses of starch granule-binding proteins by comparing the waxy wheat cultivar Shannong 119 and the bread wheat cultivar Nongda 5181. These results indicate that reduced amylose content does not affect amylopectin synthesis, but it causes significant reduction of total starch biosynthesis, grain size, weight and grain yield. Two-dimensional differential in-gel electrophoresis identified 40 differentially expressed protein (DEP) spots in waxy and non-waxy wheats, which belonged mainly to starch synthase (SS) I, SS IIa and granule-bound SS I. Most DEPs involved in amylopectin synthesis showed a similar expression pattern during grain development, suggesting relatively independent amylose and amylopectin synthesis pathways. Phosphoproteome analysis of starch granule-binding proteins, using TiO2 microcolumns and LC-MS/MS, showed that the total number of phosphoproteins and their phosphorylation levels in ND5181 were significantly higher than in SN119, but proteins controlling amylopectin synthesis had similar phosphorylation levels. Our results revealed the lack of amylose did not affect the expression and phosphorylation of the starch granule-binding proteins involved in amylopectin biosynthesis.

Spatial distribution of proteins and metabolites in developing wheat grain and their differential regulatory response during the grain filling process

Project description:Grain filling and proper grain development are essential biological processes in the plant’s life cycle, which majorly contributes to the final seed yield and quality in all cereal crop. However, very scarcely this knowledge is available in the literature regarding how the different wheat grain components contribute to the overall development of the seed. We performed a proteomics and metabolomics analysis in four different developing components of the wheat grain (seed coat, embryo, endosperm and cavity fluid) to characterize molecular processes during early and late grain development. In-gel shotgun proteomics analysis in 12, 15, 20 and 25 days after anthesis (DAA) lead us to identify and quantify 15,484 proteins out of which 410 differentially expressed proteins (DEPs) were identified in the seed coat, 815 in embryo, 372 in endosperm and 492 in cavity fluid. The abundance of selected protein candidates revealed spatially and temporally resolved protein functions associated with development and grain filling. Multiple proteins such as pyruvate phosphate dikinase (PPDK) and 14 -3- 3 undergo a major change in abundance during wheat grain development. Proteins binned into the functional category of cell growth /division were highly expressed during early stages (12 and 15 DAA) whereas those of starch biosynthesis in the middle or late stages. At the metabolome level all tissues and especially the cavity fluid showed highly distinct metabolite profiles. The tissue specific data are integrated with biochemical networks to explore a comprehensive map of molecular processes during grain filling and developmental processes.

New Insights into the Biosynthesis and Regulation of Wheat Amylose and Amylopectin from Proteomic and Phosphoproteomic Characterization of Granule-binding Proteins

Project description:Waxy starch has an important influence on bread dough and the qualities of breads. Generally, grain weight and yield in waxy wheat (Triticum aestivum L.) are significantly lower than in bread wheat. In this study, we performed the first proteomic and phosphoproteomic analyses of starch granule-binding proteins by comparing the waxy wheat cultivar Shannong 119 and the bread wheat cultivar Nongda 5181. The waxy and non-waxy wheats had similar starch granule morphological features and developmental patterns, and similar amylopectin quality in the grain. These results indicate that reduced amylose content does not affect amylopectin synthesis, but it causes significant reduction of total starch biosynthesis, grain size, weight and yield. Two-dimensional differential in-gel electrophoresis identified 40 differentially expressed protein (DEP) spots in waxy and non-waxy wheats, which belonged mainly to starch synthase (SS) I, SS IIa and granule-bound SS I. Most DEPs involved in amylopectin synthesis showed a similar expression pattern during grain development, suggesting relatively independent amylose and amylopectin synthesis pathways. Phosphoproteome analysis of starch granule-binding proteins, using TiO2 microcolumns and LC-MS/MS, showed that the total number of phosphoproteins and their phosphorylation levels in ND5181 were significantly higher than in SN119, but proteins controlling amylopectin synthesis had similar phosphorylation levels. Dynamic transcriptional expression profiling of starch biosynthesis-related genes indicated similar transcriptional expression profiles in both cultivars. Our results revealed that phosphorylation modifications played critical roles in amylose and amylopectin biosynthesis, but the lack of amylose did not affect the expression and phosphorylation of the starch granule-binding proteins involved in amylopectin biosynthesis.
