Project description:Currently unpublished data suggested that the foliar application of the Bradyrhizobium japonicum Nod factor induced changes in hormone level and enzyme activity in soybean cv. OAC Bayfield. This study was designed to examine any possible differences in gene expression that occur as a result of the foliar treatment of Nod factor. The data herein are gene expression data of that experiment, from the sprayed, first trifoliolate leaf of each plant, 48 h after treatment. Keywords: stress response

Project description:Lipo-chitooligosaccharides (LCOs) produced by N2-fixing rhizobacteria initiate host nodule formation. Foliar application of LCOs has been shown to induce stress-related genes under optimal growth conditions. To study the effects of LCO foliar spray under stressed conditions, soybean seedlings grown at optimal temperature were exposed to sub-optimal temperature. After a 5-day acclimation period, the first trifoliolate leaves were sprayed with 10-7 M LCO (NodBj-V (C18:1, MeFuc)) produced by Bradyrhizobium japonicum, and harvested at 0 and 48 h following treatment. Microarray analysis was performed using Affymetrix GeneChip® Soybean Genome Arrays. A total of 147 genes were differentially expressed 48 h after LCO treatment, including a number of stress-related genes and transcription factors. In addition, during the 48 h following treatment, hundreds of genes were differentially expressed in LCO-treated plants, indicating that the dynamic soybean foliar transcriptome was highly responsive to LCO treatment. The microarray data was supported by quantitative real-time PCR data.

The microarray data was supported by quantitative real-time PCR data. Soybean seedlings grown at optimal temperature (25 °C) were exposed to sub-optimal temperature (15 °C). After a 5-day acclimation period, the first trifoliolate leaves were sprayed with 10-7 M LCO (NodBj-V (C18:1, MeFuc)) produced by Bradyrhizobium japonicum, and harvested at 0 and 48 h following treatment. Total RNA was extracted and microarray analysis was performed using Affymetrix GeneChip® Soybean Genome Arrays.

The data herein are gene expression data of that experiment, from the sprayed, first trifoliolate leaf of each plant, 48 h after treatment. Experiment Overall Design: This experimental design was a Completely Randomized Design (CRD), comparing 1 treatment (first trifoliolate leaf sprayed with 10^-7M LCO/Nod factor and 0.02% Tween 20) against a mock-treated control (first trifoliolate leaf sprayed with dH2O and 0.02% Tween 20). There are 3 replicates per treatment type, with a total of 6 samples for this experiment.

Project description:Two potato cultivars, Russet Burbank and Bionta, were inoculated with three different endophytes containing different AHL types. The impact of the endophytes to the different cultivars was measured by gene expression analysis with a customized microarray B. phytofirmans type strain PsJN was originally isolated as a contaminant from surface-sterilized, Glomus vesculiferum-infected onion roots (Nowak et al., 1998), whereas strain P6 RG6-12 was isolated from the rhizosphere of a grassland in the Netherlands (Salles et al., 2006). This strain was selected based on its similarity to strain PsJN based on 16S rRNA gene homology, and similar phenotypic features. Both strains were generally cultivated on King's medium (King et al., 1954). For the mutant AHL to the strain B. phytofirmans PsJN a quorum quenching approach as described by Wopperer et al., 2006 was employed. Plasmid pMLBAD-aiiA, which contains aiiA, the Bacillus sp. 240B1 lactonase gene, was transferred to B. phytofirmans PsJN by triparental mating as described by de Lorenzo and Timmis (1994). 2 cultivars, 3 endophytes
