Background: Plants, involved in highly complex and well-coordinated system, have evolved a considerable degree of developmental plasticity, thus minimize the damages caused by stresses. MicroRNAs (miRNAs) have recently emerged as key regulators in gene regulation, developmental processes and stress tolerance in plants. Results: In this study, systematic discovery of soybean miRNAs associated with stress response (mock, drought, salinity and alkalinity) has been identified and analyzed in combination with deep sequencing technology and in-depth bioinformatics analysis. We found that a total of 133 conserved miRNAs corresponding to 95 miRNA families have expressed in soybean under four diverse treatments. In addition, 71, 50 and 45 miRNAs are either uniquely or differently expressed under drought, salinity and alkalinity respectively, suggesting that many miRNAs are inducible and are differentially expressed in response to certain stress. Conclusion: Our study has important implications for further identification of gene regulation under abiotic stresses and also significantly contributes a complete profile of miRNAs in Glycine max.

View SamplesThe molecular mechanisms underlying stress-influenced immune function are not clear. Chicken stress models can be established effectively by feeding chickens corticosterone hormone. The bursa of Fabricius is a unique central immune organ of birds. RNA sequencing (RNA-Seq) technology was used to investigate differences in the expression profiles of immune-related genes and associated pathways in the bursa of Fabricius to clarify molecular mechanisms. The aim of this study was to broaden the understanding of the stress-influenced immune function in chickens.

View SamplesModel topology is divided into two compartments, cell programming and performance testing. The cell programming compartment is split into history and pre-treatment. History ( History I or H1: E.coli grown for 18hrs in LB flask, transferred to fresh LB flask after that. History II or H2: E.coli grown for 18hrs in LB flask, transferred to fresh LB flask for 45 min. From this flask, 0.1O.D./ml transferred to rich medium and grown for 4 hours. From this,0.1O.D./ml transferred to fresh rich medium. History III or H3: E.coli grown for 18hrs in LB flask, transferred to fresh LB flask for 45 min. From this flask, 0.1O.D./ml transferred to starvation medium and grown for 4 hours. From this,0.1O.D./ml transferred to fresh starvation medium. Pre-treatment (Pre-treatment 1(T1): 2.5g glucose/litre 5mM NH4Cl. Pre-treatment 2 (T2): 2.5g glucose/litre 0.25mM NH4Cl. Pre-treatment 3 (T3): - 0.25g glucose/litre 5mmM NH4Cl. Pre-treatment 4 (T4): 0.25g glucose/litre 0.25mM NH4Cl). Each pre-treatment given for 2.5 hours.The culture nomenclature indicates the adaptive path followed, for example, H1T1 indicates the culture has encountered history I (H1) and then transferred to pre-treatment 1 (T1).RNA was extracted for selected combinations. Performance testing : Performance testing describes the type of analysis done which is the growth pattern study onto three substrates, glucose, succinate and pyruvate. This performance testing revealed specific history-pretreatment combinations to be better suited for growth on certain substrate and some not suited for growth. The samples were harvested for RNA isolation at peak growth points and named worst_glucose, best_glucose,worst_succinate, best_succinate, worst_pyruvate and best_pyruvate according to the growth shown after testing all 12 history-pretreatment combinations. The differences in physiology were studied in details using microarray analysis of 13 samples including 3 history samples, 4 pre-treatment samples and 6 samples at performance testing level. RNA extraction was done using Qiagen RNeasy minikit (Germany). Standard Affymetrix protocol was followed for hybridization on Affymetrix E. coli Genome 2.0 Array.

View SamplesHere, we characterize differential expression patterns associated with two chromosomal inversions found in natural Drosophila melanogaster populations. To isolate the impacts of genome structure, we engineered synthetic chromosomal inversions on controlled genetic backgrounds with breakpoints that closely match each natural inversion.

View SamplesTo investigate the basic principles of epigenetic control, we established an orthogonal epigenetic regulatory system in mammalian cells using N6-methyladenine (m6A), a DNA modification not commonly found in metazoan epigenomes. We developed a synthetic initiator module (synI) capable of establishing m6A marks in a sequence-specific manner at designer reporter loci integrated in the human genome, and a synthetic readout module (synR) which selectively reads m6A and consequently induces transcriptional changes. To ensure our orthogonal m6A system has minimal interaction with endogenous human transcriptional machineries, we performed RNA-sequencing analysis and determined that both synI and synR expression have minimal effect on 293FT transcriptome.
