(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) Over the last 30 years the soil bacterium Agrobacterium tumefaciens has been the workhorse tool for plant genome engineering. Replacement of native tumor-inducing (Ti) plasmid elements with customizable cassettes enabled insertion of a sequence of interest as “Transfer DNA” (T-DNA) into the plant genome of interest. Although these T-DNA transfer mechanisms are well understood, detailed understanding of the structure and epigenomic status of insertion events was limited by current technologies. more...

(Submitter supplied) Corning Ultra-GAPS (TM) slides are spotted with 64 pins (8x8) therefore the spotted area is divided into 3 metablocks, each containning 64 blocks of 144 spots (12x12) Protocol: A.thaliana genes were predicted with Eugene software (Foissac S. et al., Nucleic Acids Res., 2003) and gene-specific sequence tags were automatically designed (Thareau et al. Bioinformatics, 2003 Nov 22). Two rounds of PCR were performed and PCR products were finally purified and dissolved in 50% DMSO in TE at concentrations ranging between 50-200ng/ul and re-arrayed in 1536 microtiter plates. more...
