TranscriptomicsTranscription profiling of Arabidopsis callose synthase deficient (pmr4-1) mutant and wild type plants infected with powdery mildew
There were two genotypes:,(1) Columbia-0, wild-type (C),(2) pmr4-1 mutant (P), callose synthase deficient mutant (Vogel and Somerville (2000) Proc. Natl. Acad. Sci., USA 97: 1897).,There were two treatments:,(1) uninoculated (U),(2) 3 days after inoculation with the powdery mildew pathogen, Erysiph...

TranscriptomicsTranscription profiling of Arabidopsis wild type and pen3 mutant plants inoculated with powdery mildew organisms Erysiphe cichoracearum or Blumeria graminis hordei
Arabidopsis is a host to the fungal powdery mildew pathogen, Erysiphe cichoracearum, and a nonhost to Blumeria graminis f.sp. hordei, the powdery mildew pathogenic on barley. A screen for mutants that allowed increased entry by this inappropriate or nonhost pathogen on Arabidopsis led to the identif...

TranscriptomicsTranscription profiling of Arabidopsis leaves, roots and whole plants grown in high or low phosphate conditions for different lengths of time
The effects of phosphate starvation in Arabidopsis thaliana (L.) plants were compared in plants grown in liquid MS medium transferred in low or high Pi and in plants grown vertically in petri dishes during 10 days. In the transfer experiments, 2 treatments were analysed for evaluating the short-(3, ...

TranscriptomicsTranscription profiling of Arabidopsis seedlings to chito-tetramers, chito-octamers and hydrolized chitin
Using the ATH1 Affymetrix microarrays consisting of about 23,000 genes, we examined the response of Arabidopsis seedlings to chito-tetramers, chito-octamers and hydrolyzed chitin after 30 min of treatment.

TranscriptomicsEffect of elevated CO2, warming, added rainfall and added nitrogen on Geranium dissectum growing in a natural grassland
We used microarrays to discern patterns of gene expression in response to global climate change factors on leaf tissue of an annual dicot, Geranium dissectum, growing in a natural grassland. Keywords: multifactorial global change treatments There are 5-8 biological replicates for each of the sixteen...
