(Submitter supplied) Agrobacterium tumefaciens is a special plant pathogen causing crown gall disease. This pathogen is well known for the technology Agrobacterium-mediated transformation. As a pathogen, Agrobacterium triggers plant immunity, and this affects transformation. But the signaling components and pathways in plant immunity to Agrobacterium remain elusive. We demonstrate two Arabidopsis MAPKKs MKK4/MKK5 and their downstream MAPKs MPK3/MPK6 play a major role in both Agrobacterium-triggered immunity and Agrobacterium-mediated transformation. more...

(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) Effector-Triggered Immunity (ETI) and Pattern-Triggered Immunity (PTI) are well-defined modes of plant immunity triggered by recognition of pathogen effector proteins and microbe-associated molecular patterns, respectively. While ETI and PTI network extensively share signaling components, the shared components are used in different ways, resulting in distinct network properties in the model plant Arabidopsis: immunity is highly robust against network perturbations in ETI but relatively sensitive in PTI. more...

(Submitter supplied) MPK6 shows transient increase in activity under hypoxia with maximal activity at 2 hrs. To study the role of MPK6 in hypoxia in Arabidopsis, 10 do seedlings of WT, mpk6 and MPK6 plants were exposed to 2 hrs hypoxia and 2hr air (mock). Because there are no major phenotypic differences between the genotypes, microarray was used to determine if there were transcript level differences between the genotypes.
