(Submitter supplied) This study describes physiological changes, morphological adaptations and the regulation of pathogen defense responses in Arabidopsis crown galls. Crown gall development was induced on intact plants under most natural conditions with Agrobacterium tumefaciens. Differential gene expression and the metabolite pattern was determined by comparing crown galls with mock-inoculated inflorescence stalk segments of the same age.

(Submitter supplied) The intention of these gene expression analysis was to study host responses to an infection with Agrobacterium tumefaciens at different stages of crown gall development. Therefore the transcriptome of infected inflorescence stalk tissue and mature crown galls of Arabidopsis thaliana (WS-2) was determined of three different time points. These were compared with the transcriptome of mock-infected inflorescence stalk tissue (reference) of the same age. more...

(Submitter supplied) This study focuses on responses of the host plant to infection and transformation with Agrobacterium tumefaciens. Genome wide changes in gene expression were integrated with the alterations in metabolite levels six days after inoculation of agrobacteria. Plants were infected with the virulent strain C58, harboring a T-DNA, or with strain GV3101, containing a disarmed Ti-plasmid. This allows discrimination between signals which derive from the bacterial pathogen and the T-DNA encoded genes.

(Submitter supplied) Integration of the bacterial T-DNA into the plant genome by virulent agrobacteria causes crown gall development on many plant species. Plant tumor development shares fundamental similarities with mammalian cancer progression despite obvious differences in initiation of tumor development. For neoplastic growth in mammals, DNA methylation changes are known to be essential. The role of epigenetic modifications for plant tumor development is addressed here. more...

(Submitter supplied) ABA-signaling in disitinct root tissues is important for xylem phenotypes observed both under mock and ABA-treatment. We performed RNA-sequencing on Arabidopsis plants in which ABA-signalling is specifically blocked in the endodermis (J0571), the xylem (J1721) or the procambium (Q0990) to investigate the underlying transcriptomic changes.

(Submitter supplied) The ubiquitin 26S proteasome system (UPS) selectively degrades cellular proteins, which results in physiological changes to eukaryotic cells. F-box proteins are substrate adaptors acting within the UPS and are responsible for the diversity of potential protein targets. Plant genomes are enriched in F-box genes, but the vast majority of these have unknown roles. This work investigated the Arabidopsis F-box gene F-BOX STRESS INDUCED 1 (FBS1) by identifying differentially expressed genes between wild type (No-0) and an fbs1 insertion line. more...

(Submitter supplied) Seed germination is a critical developmental process in plant propagation. Knowledge of the gene expression patterns in this critical process is important in order to understand the main biochemical reactions involved in successful germination, specially for economically relevant plants such as Maize. The purpose of this study is the gene expression analysis of quiescent and germinated maize embryonic axes to determine the regulatory mechanism for (r)-protein expression during the maize development process.

(Submitter supplied) The pathogen Agrobacterium tumefaciens infects a broad range of plants, introducing the T-DNA into their genome. Contrary to all known bacterial phyto-pathogens, Agrobacterium lacks the hypersensitive response-inducing HRP genes although it introduces numerous proteins into the plant cell through a type IV secretion system. To understand the timing and extent of the plant transcriptional response to this unusual pathogen, we used an Arabidopsis 26-thousand gene oligonucleotide microarray. more...

Analysis of LER cells up to 48 hours after infection with oncogenic Agrobacterium tumefaciens (A.t.). Unlike all known bacterial phytopathogens, broadly-infectious A.t. lacks the hypersensitive response-inducing HRP genes. Results identify the host transcriptional response to this unusual pathogen.

(Submitter supplied) Here we report on the identification of Arabidopsis genes that are induced during compatible but not during incompatible interactions with the downy mildew pathogen Hyaloperonospora arabidopsidis. This set of so-called compatible specific (CS) genes contrasts the large group of defence-associated genes that is differentially expressed during both compatible and incompatible interactions. From the 17 identified CS-genes, 6 belong to the ERF family of transcription factor genes, suggesting that these ERFs have a role during compatibility. more...

(Submitter supplied) The goal of this experiment was to explore the extent of KIN10 (At3g01090) transcriptional regulation and identify its early target genes in Arabidopsis mesophyll protoplasts. Results suggest that KIN10 targets a remarkably broad array of genes that orchestrate transcription networks, promote catabolism and autophagy, and suppress anabolism and ribosome biogenesis. The transient expression condition ruled out secondary or long-term effects of metabolism and growth, and circumvented experimental limitations caused by redundancy and embryonic lethality observed in mammals and plants. more...
