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.

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.

View SamplesExcessive accumulation of lipids in the adipose tissue is a major problem in the present-day broiler industry. However, few studies have analyzed the expression of adipose tissue genes that are involved in pathways and mechanisms leading to adiposity in chickens. Gene expression profiling of chicken adipose tissue could provide key information about the ontogenesis of fatness and clarify the molecular mechanisms underlying obesity.

View SamplesPlant BZR1-BAM transcription factors contain a -amylase (BAM)-like domain, characteristic of proteins involved in starch breakdown. The enzyme-derived domains appear to be non-catalytic, but determine the function of the Arabidopsis thaliana BZR1-BAMs (BAM7 and BAM8) during transcriptional initiation. Microarray experiments with plants overexpressing different mutant versions of the proteins show that only functional BZR1-BAM variants deregulate gene expression and cause leaf developmental abnormalities. Transcriptional changes caused by overexpression of the BZR1 domain alone indicate that the BAM domain increases selectivity for the preferred cis-regulatory element BBRE (BZR1-BAM Responsive Element).

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.
