Gene Expression Profiling of Glycine max Cotyledons and Trifoliate Leaves to Determine Genes Associated with Senescence

ABSTRACT: We use RNA sequencing technology in a time course study to measure transcript abundance from three developmental stages in cotyledons and five stages in the trifoliate leaf of Glycine max to identify genes with distinct temporal patterns of expression during leaf or cotyledon development. We also examine the differences between these two photosynthetic tissues. Time course Expression analysis of Cotyledon Development and Leaf Development using RNAseq on distinct time points. 3 stages of the cotyledon were sequenced with 3 biological replicates in each stage. Five stages of the leaf, determined by physical appearance and plant developmental stage, were collected from the time of soil emergence to the onset of senescence and were sequenced with 3 biological replicates for each stage.

Developmental profiling of gene expression in soybean trifoliate leaves and cotyledons.

Brown Anne V AV Hudson Karen A KA

BMC plant biology 20150703

<h4>Background</h4>Immediately following germination, the developing soybean seedling relies on the nutrient reserves stored in the cotyledons to sustain heterotrophic growth. During the seed filling period, developing seeds rely on the transport of nutrients from the trifoliate leaves. In soybean, both cotyledons and leaves develop the capacity for photosynthesis, and subsequently senesce and abscise once their function has ended. Before this occurs, the nutrients they contain are mobilized and ...[more]

Genome-Wide Transcript Profiling During Soybean Seed Development and Throughout the Soybean Life Cycle

Project description:We report the genome-wide transcriptome of soybean seeds across several stages of seed development and the entire life cycle using Illumina high-throughput sequencing technology. Specifically, we profiled whole seeds containing globular-stage, heart-stage, cotyledon-stage, and early maturation-stage embryos. We also profiled dry soybean seeds, and vegetative and reproductive tissues including leaves, roots, stems, seedlings, and floral buds. Illumina sequencing of transcripts from whole seeds at five stages of seed development (globular, heart, cotyledon, early-maturation, dry), and vegetative (leaves, roots, stems, seedlings) and reproductive (floral buds) tissues.

Analysis of soybean DNA methylomes shows CHH hypermethylation enhances gene expression in cotyledons of developing seeds [methylome]

Project description:Cytosine methylation is an important mechanism for dynamical regulation of gene expression and transposon mobility during plant developmental processes. Recently, the variation of DNA methylation has been described between wild type and DNA methylation-related mutants in Arabidopsis thaliana. However, the elaborate representation of soybean DNA methylomes remains lacking. Here, we described the epigenome maps of soybean root, stem, leaf, and cotyledon of developing seed at a single-base resolution. We confirmed the transcription start sites of genes using high-throughput sequencing and reported the DNA methylation patterns in gene and transposon regions. The correlation between gene expression and DNA methylation was revealed through transcriptome sequencing. We found CHH methylation may function in promotion of gene expression and ten cotyledon-preferred genes were identified CHH hypermethylated in cotyledon. Small RNA library sequencing showed that DNA methylation was enhanced by small RNAs not by strand-specific way, and the variation of DNA methylation between the organs was highly related with expression of small RNAs. methylomes of roots, stems, leaves, and cotyledons of developing seeds

Methylation Changes in Arabidopsis seed development

Project description:There are four major seed developmental phases in Arabidopsis seed development: morphogenesis, maturation, dormancy and germination. What methylation changes occurring in the different phases, if any, remains unknown. To uncover the possible role of DNA methylation in different parts of the seed, we characterized the methylome of four major seed developmental phases of Arabidopsis using Illumina sequencing: global stage (glob) and linear cotyledon stage (lcot) for morphogenesis phase; mature green stage (mg) and post mature green stage (pmg) for maturation phase; dry seed (dry) for dormancy phase; leaves (leaf) from 4 week plant for vegetative tissues. Illumina sequencing of bisulfite-converted genomic DNA from six seed developmental stages in Arabidopsis: global stage (glob), linear cotyledon stage (lcot), mature green stage (mg), post mature green stage (pmg), dry seed (dry) and leaves (leaf) from 4 week plant.

Identification of soybean seed developmental stage specific and tissue specific miRNA targets by degradome sequencing .

Project description:Five degradome libraries were constructed from three different seed developmental stages. Separate degradome libraries were constructed for seed coat and cotyledons to identify the tissue specific miRNAs and their potential targets. Sequencing and analysis of degradome libraries gives identification of 183 different targets for 80 known soybean miRNAs. We found 30 cotyledon specific, 18 seed coat specific and 32 miRNAs found in both tissues irrespective of the developmental stages. One interesting observation is that we found more miRNA targets in late seed developmental stages than earlier stages. Additionally, we have validated four different auxin response factor genes as targets for gma-miR160 via RNA ligase mediated 5? rapid amplification of cDNA ends (RLM-5?RACE). GO analysis indicated the enrichment of miRNA target genes in seed development. Construction of degradome libraries using cotyledons and seed coats from 3 different developmental stages

Evaluation of genes involved in watermelon fruit ripening and development

Project description:A microarray and quantitative Real-Time PCR-based study was conducted in watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus] in order to elucidate the flow of events associated with fruit development and ripening in this species. RNA from three different maturation stages of watermelon fruit, as well as leaf, were collected from field grown plants during three consecutive years, and hybridized to high-density, photolithography microarrays. Keywords: developmental time course, gene expression This experiment contained a single biological replicate, two tissue types (leaf, fruit flesh), and three time points (12 days post-pollination, 24 days post-pollination, and 36 days post-pollination. One hundred and twenty-seven genes were chosen from this experiments and used in conjunction with quantitative-PCR to examine two additional biological replications of the experiment.

Proteome Analysis of rapeseed Cotyledons to Light

Project description:Among multiple factors, light plays a decisive role in the switch from heterotrophic to autotrophic growth. Under dark condition, the rapeseed hypocotyl extended quickly with an apical hook, yellow and folded cotyledon, and the glyoxysome assembling. Whereas under light, the hypocotyl extended slowly, the cotyledon unfolded and turned green. In this study, we performed proteome profiling analyses to show the differential molecular responses of Brassica napus cotyledons to light and dark and reveal metabolic adaptations in postgerminative seedling establishment. In both light and dark-grown conditions.

Comparative transcriptome profiling of Arabidopsis lyrata and Arabidopsis thaliana

Project description:Arabidopsis thaliana and Arabidopsis lyrata are two closely related Brassicaceae species, which are used as models for plant comparative biology. They differ by lifestyle, predominant mating strategy, ecological niches and genome organization. In order to explore molecular basis of specific traits, we performed RNA-sequencing of vegetative rosettes from both species. Additionally, we sequenced apical meristems and inflorescences of A. lyrata that allow for intra-specific transcriptome comparison in several major developmental stages. Arabidopsis lyrata and Arabidopsis thaliana aerial tissues were collected from mock treated plants, total RNA isolated and poly-A RNA populations sequenced
