Chromatin immunoprecipitation of Zea mays chloroplast extracts using antibodies raised against OE17 and OE23 chloroplast targeted proteins

ABSTRACT: OE17 and OE23 are chloroplast targeted proteins. RNA co-immunoprecipitation was performed using antibodies raised against these proteins. RNA from the pellet and from the supernatent for each pulldown was labeled with different fluoro-dyes.

The pentatricopeptide repeat (PPR) is a degenerate 35-amino acid repeat motif that is widely distributed among eukaryotes. Genetic, biochemical, and bioinformatic data suggest that many PPR proteins influence specific posttranscriptional steps in mitochondrial or chloroplast gene expression and that they may typically bind RNA. However, biological functions have been determined for only a few PPR proteins, and with few exceptions, substrate RNAs are unknown. To gain insight into the functions an ...[more]

Chromatin immunoprecipitation of Zea mays chloroplast extracts prepared from wild type and CRP1-deficient tissue

Project description:Identification of target transcripts for the putative chloroplast RNA binding protein CRP1 in Zea mays. CRP1 was immunoprecipitated from a chloroplast extract. Chloroplast extracts were prepared from WT and CRP1-deficient tissue. RNA from the pellet and from the supernatant for each pulldown was labelled with different fluoro-dyes and hybridized onto an array covering the complete maize chloroplast genome. Messages enriched in the immunoprecipitate from WT tissue, but not enriched in mutant tissue are likely targets for CRP1.

ECBiG PlasTi-microarray CSH validation

Project description:Experiment evaluating aplicability of PlasTi-microarray for cross-species hybridization studies. PlasTi-microarray is a tiling oligonucleotide microarray originally designed for cucumber plastome analysis.Chloroplast RNA from Arabidopsis, tomato and spinach leaves was extracted, labelled and hybridized to PlasTi-microarray with the cucumber samples labelled with the second dye as a control. For each species, one biological sample and one technical replicate (labelled in a dye-swap orientation) were analyzed, resulting in two microarray hybridizations per species and six microarrays (a-f) in total.

Meta-transcriptome analysis of a natural wheat sourdough ecosystem during a 10-day spontaneous, laboratory fermentation

Project description:Lactic acid bacteria (LAB) are of industrial importance in the production of fermented foods, among which sourdough-derived products. Despite their limited metabolic capacity LAB contribute considerably to important characteristics of fermented foods, among which extended shelf-life, microbial safety, improved texture, and enhanced organoleptic properties. Thanks to the considerable amount of LAB genomic information that became available during the last years, transcriptome, and by extension meta-transcriptome studies, are the exquisite research approaches to study whole ecosystem gene expression into more detail. In this study, microarray analyses were performed using RNA sampled during four 10-day spontaneous sourdough fermentations carried out in the laboratory, namely two wheat and two spelt fermentations with daily back-slopping. Hereto, the in-house developed functional gene LAB microarray was used, representing 406 genes that play a key role in sugar and nitrogen metabolism, functional metabolite production, stress responses and health and safety characteristics. The results reveal the activation of different key metabolic pathways, the ability to use different energy sources, and successful acid and oxidative stress responses. Also, a new algorithm was developed to compute a net expression profile for each of the represented genes, thereby exceeding the species level. The labeled aRNA of the sourdough fermentation samples was hybridized using a loop design, i.e. subsequent samples (e.g. 27 h and 51 h, 51 h and 75 h etc.) were hybridized together on the microarray and the loop was closed by hybridizing the last sample with the first.
