Physcomitrella patensTranscriptome or Gene expression

ABSTRACT: We used heat shock (HS) treatments and high-throughput mRNA sequencing to obtain HS transcriptomes in the moss Physcomitrella patens. Besides revealing differential gene expression at the transcriptional level, a transcriptome survey identified abundant AS events in the single-cellâtype, undifferentiated, moss protonemal cell. For preparing RNA-seq samples, protonemal colonies were grown at 38Â°C for 1 h (1st HS), recovered at 25Â°C for 5.5 h, and then grown at 38Â°C again for 1 h (2nd HS). Cells remaining at 25Â°C were collected as the control. Note: All samples in SRA were assigned the same sample accession (SRS402930). This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Genome-Wide Analysis of Heat-Sensitive Alternative Splicing in Physcomitrella patens.

Chang Chiung-Yun CY Lin Wen-Dar WD Tu Shih-Long SL

Plant physiology 20140428 2

Plant growth and development are constantly influenced by temperature fluctuations. To respond to temperature changes, different levels of gene regulation are modulated in the cell. Alternative splicing (AS) is a widespread mechanism increasing transcriptome complexity and proteome diversity. Although genome-wide studies have revealed complex AS patterns in plants, whether AS impacts the stress defense of plants is not known. We used heat shock (HS) treatments at nondamaging temperature and mess ...[more]

Physcomitrella patens cultivar:Gransden Transcriptome or Gene expression

Project description:In this study we used single-cell type transcriptomics to identify more than 4,000 differentially expressed (DE) genes that distinguish uniplanar protonematal tip cells from multiplanar gametophore bud cells in the moss Physcomitrella patens. While the transcriptomes of both tip and bud cells harbor molecular signatures of proliferative cells, the bud cell transcriptomes exhibit a wider variety of upregulated genes. Our data suggest that the combined expression of genes regulating shoot patterning and asymmetric cell division accompanied the transition from uniplanar to triplanar meristematic growth in moss.

transcriptome sequencing of tomato

Project description:Gene expression of all tomato genes was determined by replicated (two biological replicates of each tissue) strand-specific Illumina RNA-Seq of root, leaf, flower (2 stages) and fruit (6 stages). Note: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Populus tricho Raw sequence reads

Project description:We performed RNA-Seq of P. trichocarpa calluses that were firstly induced from roots. Then the total RNAs were isolated from the control and salt-stressed calluses (200 mM NaCl for 6, 12, 24, and 48 h) using a CTAB procedure. Note: All samples in SRA were assigned the same sample accession (SRS938530). This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values.

Solanum lycopersicum strain:M82 Transcriptome or Gene expression

Project description:We sequenced mRNA from immature green (15 days after anthesis) and red (Breaker+10 days) tomato (Solanum lycopersicum) fruit tissues from plants over-expressing SlGLK1 and SlGLK2 and from control plants 'M82' to compare gene expression levels between transgenic fruit and the control. Note: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence “Source Name” was replaced with new values.

Transcript profiling of the biotrophic interaction between Theobroma cacao and the fungal pathogen Moniliophthora perniciosa

Project description:RNA-seq to simultaneously inspect the transcriptomes of cacao and M. perniciosa during their biotrophic interaction. Five biological replicates of each condition (healthy seedlings and seedlings at 30 d after infection) were harvested for transcriptome sequencing using RNA-seq. For this experiment, the entire green broom structure was collected, including cacao leaves and shoots. Samples in SRA were assigned the same sample accession (SRS396688, SRS396689). 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.

Oryza sativa Japonica strain:EFR-XA21 | cultivar:Kitaake Transcriptome or Gene expression

Project description:We analyzed the transcriptomic profile of EFR:XA21:GFP rice lines treated with elf18 to identify genes differentially regulated during this response. We sequenced cDNA from EFR:XA21:GFP leaves treated with 500 nM elf18 for 0.5, 1, 3, 6, and 12 h. We also included untreated EFR:XA21:GFP and Kitaake as controls. Note: All samples in SRA were assigned the same sample accession (SRS843490). This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values.

Triticum aestivum Transcriptome or Gene expression

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.

Oryza sativa Transcriptome or Gene expression

Project description:The transcriptomes of resistant BPH15 introgression line and the susceptible recipient line were analyzed using high-throughput RNA sequencing. In total, 2,914 differentially expressed genes (DEGs) were identified. BPH-responsive transcript profiles were distinct between resistant and susceptible plants and between the early stage (6 h after infestation, HAI) and late stage (48 HAI). The key defense mechanism was related to jasmonate signaling, ethylene signaling, receptor kinase, MAPK cascades, Ca2+ signaling, PR genes, transcription factors, and protein post-translational modifications. Note: All samples in SRA were assigned the same sample accession (SRS565690 and SRS565691). This is incorrect as there are different samples, hence Source Name was replaced with new values.

Comparison of basal gene expression strengths between Schrenkiella parvula and Arabidopsis thaliana

Project description:Using RNA sequencing, we compared transcriptomes of root and aerial tissues of S. parvula and Arabidopsis and identified genes and pathways with significantly different basal expression strengths. Many stress-related ion transporter genes in S. parvula showed increased copy numbers and basal expression strengths compared with Arabidopsis, with evidence of subfunctionalization. These results provide a blueprint for mechanisms of plant ion stress tolerance as well as potential genetic resources for crop improvement in closely related species. Note: All samples in SRA were assigned the same sample accession (SRS845940 and SRS845941). 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.
