Volatiles of certain rhizobacteria can cause growth inhibitory effects on plants/ Arabidopsis thaliana. How these effects are initiated and which mechanisms are enrolled is not yet understood. Obviously the plant can survive/live with the bacteria in the soil, which suggest the existance of a regulatory mechanism/network that provide the possibility for coexistance with the bacteria. To shed light on this regulatory mechanism/network we performed a microarray anlaysis of Arabidopsis thaliana co-cultivated with two different rhizobacteria strains.
Volatiles of two growth-inhibiting rhizobacteria commonly engage AtWRKY18 function.

View SamplesCaryopses of barley (Hordeum vulgare), like all other cereal seeds, are complex sink organs optimized for storage starch accumulation and embryo development. Their development from early stages after pollination to late stages of seed ripening has been studied in great detail. However, information on the caryopses diurnal adaptation to changes in light, temperature and alterations in phloem-supplied carbon and nitrogen remained unknown.
Significance of light, sugar, and amino acid supply for diurnal gene regulation in developing barley caryopses.

View SamplesPlant BBR/BPC transcription factors contain the conserved Basic-Pentacystein (BPC) DNA-binding domain. Arabidopsis group II BBR/BPC proteins interact with PRC1 component LHP1 in vivo. Microarray experiments with Arabidopsis bpc4 bpc6, lhp1-4 and lhp1-4 bpc4 bpc6 suggest an importance of this interaction in the concerted repression of homeotic genes.

View SamplesIn order to identify genes with different overall transcript levels or differential exon levels (alternative processing) between the groups Control and Tat-SF1KD, we studied 11 hybridizations on the HumanExon10ST array using mixed model analysis of variance. 526 genes with significant transcript level differences between the groups and 1397 genes with significant differential exon levels were found, including 99 genes with both transcript and exon level differences (p<0.01).
Identification of Tat-SF1 cellular targets by exon array analysis reveals dual roles in transcription and splicing.
