Project description:Applying a gel-based proteomic approach, the dynamic changes in root proteins of drought treated Quercus ilex subsp. Ballota [Desf.] Samp. seedlings were followed. Water stress was applied on 20 day-old holm oak plantlets by water limitation for a period of 10 and 20 days, each followed by 10 days of recovery. Root proteins were extracted using trichloroacetate/acetone/phenol protocol and subjected to two-dimensional electrophoresis. Coomassie colloidal stained gel images were analysed and spot intensity data subjected to multivariate statistical analysis. Selected consistent spots in the three biological replicas, presenting significant changes under stress, were subjected to MALDI-TOF mass spectrometry (peptide mass fingerprinting and MS/MS). For protein identification, combined search was performed with MASCOT search engine over NCBInr Viridiplantae and Uniprot databases. Taxonomy Holm oak (Quercus ilex subsp. Ballota [Desf.] Samp.).

Project description:The coordination of chloroplast and nuclear genome status are critical for plant cell function, but the mechanism remain largely unclear. In this study, we report that Arabidopsis thaliana CHLOROPLAST AND NUCLEUS DUAL-LOCALIZED PROTEIN 1 (CND1) maintains genome stability in both the chloroplast and the nucleus.

Project description:We performed chloroplast ChIP-seq (cpChIP-seq) to identify the possible DNA-binding sites of mTERF5 in Arabidopsis thaliana. To this end, we generated transgenic Arabidopsis plants expressing mTERF5 carrying an HA tag under the control of the CaMV 35S promoter. Then, We used the polyclonal antibody (abcam, ab9110, lot GR304617-8 ) against HA tag which conjugated to ChIP-Grade protein A/G agarose (Thermo scientific, 26161, lot QJ223903) to perform cpChIP assay. The obtained chromatin immunoprecipitated DNA of chloroplasts were used to build DNA libaries for high-throughput sequencing. Finally, we showed that three potenssial DNA regions across the chloroplast genome compared to the control group were enriched by mTERF5.

Project description:Purpose: The chloroplast DNA has not been primiarly analyzed in rice plants before. Hence, the objective of this study is to analyze and compare the differential methylation of chloroplast DNA in MR219 indica rice across different tissues and different developmental stages. Methods: We prepared a total of nine sodium bisulfite treated DNA libraries from three developing grain tissues, three leaf tissues at ripening stage and three leaf tissues at vegetative stage and sequenced them in Illumina Miseq platform. We performed quality trimming, alignment followed by methylation calling and differential methylation analysis using Trimmomatic v36, Bismark v16.3 and SeqMonk v40.0 on the sequencing data obtained. Statistical analysis was carried out in SeqMonk software and further validated in SPSS statistical software v22.2. Results: With an optimized data analysis workflow, we mapped around average of 26000 reads to chloroplast genome. Differential CpG and CHG methylation in SeqMonk v40.0 revealed that MR219 chloroplast DNA is differentially methylated in grain and leaf tissues and across vegetative stage and ripening stage in the leaf tissues. Chloroplast DNA from leaf at ripening stage was most methylated, followed by grain tissue and lastly leaf tissue from vegetative stage. Conclusions: Overall, it can be concluded that the organellar DNA in MR219 rice are differentially methylated at different tissues and across different developmental stages. The chloroplast DNA was most methylated in the leaf at ripening stage, followed by grain at ripening stage and leaf at vegetative stage. The functional significance of the differential methylation observed in this study needs to be investigated.
