Project description:Transcript profile of apices of 20 days-old Arabidopsis plants over expressing miR396b. We used ATH1 Affymetrics microarrays to obtain the transcription profile of plants overexpressing miR396b. We compared the transcriptome of 35S:miR396b plants vs wild-type plants (Col-0 accession), using ATH1 Affymetrics microarrays. For these experiments we collected vegetative apices together with the leaf primordia from plants of 20 days growth in short-day. For each genotype (Col-0, 35S:miR396b) we collected two samples.

Project description:The Growth Regulating Factors (GRFs) are plant specific transcription factors. They form complexes with GRF Interacting Factors (GIFs), a small family of transcriptional co-activators. In Arabidopsis thaliana, seven out of the nine GRFs are regulated by microRNA miR396. A detailed analysis of GRF3 revealed that a modified transgene, insensitive to the regulation of miR396, causes a strong increase in the number of cells in leaves, while an additional increase of GIF1 expression further enhances the number of cells synergistically. Genome-wide transcript profiling revealed that simultaneous increase of GRF3 and GIF1 levels causes additional effects in gene expression compared to either of the transgenes alone. We observed that GIF1 interacts in vivo with GRF3, as well as chromatin remodeling complexes, providing a mechanistic explanation for the additional activities of a GRF3-GIF1 complex. Interestingly, we found that the GRF system also regulates leaf longevity. Genetic and molecular analysis revealed that the functions of GRFs in leaf size and senescence can be uncoupled, demonstrating that the GRFs control different stages of leaf development. The results provide new insights into the functions of a complex regulatory network composed of microRNAs, transcription factors, and co-transcription factors. We used microarrays to obtain the transcription profile of plants overexpressing GRF3, GIF1 or both genes toghether. We compared the transcriptome of 35S:GIF1, rGRF3 and rGRF3x35S:GIF1 plants vs wild-type plants (Col-0 accession), using ATH1 Affymetrics microarrays. For these experiments we collected vegetative apices together with the leaf primordia from plants of 20 days growth in short-day. For each genotype (Col-0, rGRF3, 35S:GIF1 and rGRF3x35S:GIF1) we collected two samples.

Project description:Microarray analysis of wild type plants and plants with reduced (ago1-27 and se-1) or increased miR156 levels (se-1 p35S:MIR156). Shoot apices were dissected from 20-day-old, short-day grown plants.

Project description:Transcriptomic profile of Arabis alpina apex enriched material. We compared apices from plants grown for 2 weeks in long days (20°C) (juvenile) with apices from plants grown for 8 weeks in long days (20°C) (adult) and apices from plants grown for 2 weeks and then shifted in vernalization for 4 weeks with apices from plants grown for 8 weeks and than shifted to vernalization for 4 weeks.

Project description:In plants, MAPKs are implicated in signalling cascades regulating immediate as well as systemic responses to pathogens. Arabidopsis MAP kinase 4 (MPK4) negatively regulates systemic acquired resistance (SAR) accompanied by the expression of pathogenesis-related (PR) genes. MPK4 interacts with and phosphorylates MKS1. Plants that over-express MKS1 exhibit constitutive SAR. RNA was independently isolated three times from each of the three genotypes, wild-type, mpk4 and 35S:mks1 and hybridized to nine Affymetrix ATH1 GeneChips.

Project description:Arabidopsis Affymetrix ATH1 GeneChips were used to compare the mRNA profiles of root tissues of the transgenic plants overexpressing 4D09 effector gene from the cyst nematode Heterodera schachtii and the wild-type (C24). Also, Arabidopsis Affymetrix ATH1 GeneChips were used to compare the mRNA profiles of root tissues of the transgenic plants overexpressing 14-3-3Ɛ gene from Arabidopsis and the wild-type (Col-0). Wild-type (Arabidopsis thaliana, ecotypes C24 and Col-0 ), and the transgenic plants overexpressing 4D09 effector gene or overexpressing 14-3-3Ɛ gene from Arabidopsis were grown in vertical culture dishes on modified Knop’s medium for 2 weeks and then root tissues were collected for RNA extraction. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Tarek Hewezi.

Project description:Fungal effectors play important roles in inciting disease development on host plants. We identified an effector (Secreted in Xylem4, SIX4) in an Arabidopsis infecting isolate (Fo5176) of the root-infecting fungal pathogen Fusarium oxysporum and demonstrated this effector is required for full virulence. To explore the role of Fo5176_SIX4 we use whole transcriptome profiling of root tissues from plants overexpressing this effector (35sSIX4) versus wild-type (Col-0) plants after F. oxysporum infection. We grew both WT and 35sSIX4 plants for four weeks in soil. After four weeks the plants were infected with Fusarium oxyporum isolate Fo5176, trays covered with a plastic dome and incubated at 28C. There were four independent replicates of each treatment and each replicate contained root tissue from 20 plants. Each replicate (8 in total) was harvested 4 days post inoculation and the resulting RNA was used for hybridization to an Affymetrix ATH1 chip.
