Project description:Little is known about plant pathogenic response to parasitic plants, although some parasitic plants affect crop production in certain areas. To study this, we chose Glycine max as the model host plant and investigated changes in expression patterns after parasitization by Cuscuta using microarrays. Transcriptional change of Glycine max stem with and without Cuscuta at 2 different stages were compared

Project description:We aimed to identify miRNA regulated by alternate bearing in O. europaea. For this purpose, six olive (Olea europaea L. )(Ayvalık variety) small RNA libraries were constructed from fruits (ripe and unripe) and leaves ("on-year" and "off-year" mature -leaven in November and juvenile - leaven in July plants) and sequenced by high-throughput Illumina sequencing. Bioinformatics analyses of 93,526,915 reads identified 135 conserved miRNA, belonging to 22 miRNA families in olive tree. In addition, 38 novel miRNA were discovered in the datasets. Expression of olive tree miRNA varied greatly among the six libraries, indicating contribution of diverse miRNA in balancing between reproductive and vegetative phases. The differential expression of miRNA was evaluated on the basis of the developmental phase of the samples. Sequences of six olive miRNAs (Olea europaea L. )(Ayvalık variety) plants (ripe and unripe fruits, leaves of mature and juvenile plants of both "on-year" and "off-year") were generated by Illumina sequencing

Project description:Backgroud: microRNA (miRNA) is implicated in plant development processes, playing pivotal roles in plant adaptation to environmental stresses. Salicornia europaea, a salt mash euhalophyte, is a good model plant to study salt adaptation mechanisms. It is also attractive in being vegetables, forage and oilseed that can be used for saline land reclamation and biofuel precursor production on marginal lands. However, none of the miRNAs from S. europaea have been identified so far. Results: Deep sequencing was performed to investigate small RNA transcriptome of S. europaea. Two hundred and twelve conserved miRNAs comprising 51 families and 31 novel miRNAs (including 7 miRNA star sequences) belonging to 30 families were identified. Interestingly, about half (13 out of 31) of the novel miRNAs were only detected in salt-treated samples. The expression of 43 conserved and 13 novel miRNAs changed significantly in response to salinity. In addition, 53 conserved miRNAs and 13 novel miRNAs were differentially expressed between shoots and roots. Furthermore, a total of 306 and 195 S. europaea unigenes were predicted to be targets of 41 conserved and 29 novel miRNA families, respectively. These targets encode a wide range of proteins, and genes involved in transcription regulation constitute the largest category. Four of them, which encode laccase, F-box family protein, SAC3/GANP family protein, and nadph-cytochrome P450 oxydoreductase, were validated using 5'-RACE. Conclusions: Our results indicate specific miRNAs are tightly regulated by salinity in shoots and/or roots of S. europaea, which play important roles in salt adaptation of this euhalophyte. The S. europaea salt-responsive miRNAs and miRNAs that target transcription factors, nucleotide binding site-leucine-rich repeat proteins and enzymes involved in lignin biosynthesis as well as carbon and nitrogen metabolism may be applied in genetic engineering of crops with higher stress tolerance, and genetic modification of biofuel crops with higher biomass and regulatable lignin biosynthesis.

Project description:Heavy metals have been postulated as significant nitrification inhibitor in wastewater treatment plant. The effect of heavy metals such as Cd2+, Cu2+ and Hg2+ to nitrifying bacterium, Nitrosomonas europaea, was studied in pseudo-steady state batch reactor. Under incubation of Nitrosomonas europaea with 1 ?M CdCl2 for 1 hour, transcripts for 66 of 2460 genes were found at high level, yet transcripts of 50 genes were found at low level. Mercury resistance genes (merACDPT) showed 277-fold up regulation. Keywords: cadmium, stress response, global transcription, mercury resistance genes, merA,
