Changes in life history traits and transcriptional regulation of Coccinellini ladybirds in using alternative prey

tailieu.vn

Changes in life history traits and. transcriptional regulation of Coccinellini ladybirds in using alternative prey. Results: In this study, comparisons of the life history traits and transcriptomes of ladybirds fed initial (aphids) and alternative prey (mealybugs) were performed in three Coccinellini species. The use of alternative prey greatly decreased performance, implied by the significantly prolonged development time and decreased survival rate and adult weight.

The landscape of lncRNAs in Cydia pomonella provides insights into their signatures and potential roles in transcriptional regulation

tailieu.vn

Furthermore, the correlation analysis of lncRNAs with neighbouring PCGs indicated a stronger correlation between them, suggesting potential cis-acting roles of these lncRNAs in the regulation of gene expression.. Due to their larger size and more complex secondary structure, the mechanisms of ac- tion of lncRNAs are highly diversified. The regulation of lncRNAs can encompass multi-layered activities, mainly at the pre-transcriptional, transcriptional and post- transcriptional levels.

Genome-scale analyses of transcriptional start sites in Mycobacterium marinum under normoxic and hypoxic conditions

Comparison of Cappable-seq and regular RNA-seq in global transcriptional regulation analyses. We next compared the data in Cappable-seq with our data in regular RNA-seq to confirm the efficiency of Cappable-seq in the global analysis of transcriptional regulation. As expected, most of the genes showed similar patterns of regulation in both methods (Fig. To- gether, these analyses indicate that Cappable-seq is a valuable method for transcriptional analysis..

Transcriptional landscape of the embryonic chicken Müllerian duct

Their role in the Müllerian duct is speculative, but lncRNAs in other tissues can have a range of functions, from chromatin modification and transcriptional regulation in the nucleus through to translational regulation and microRNA modulation in the cytoplasm [112].. We and others have used in ovo electroporation to manipulate endogenous gene expression in the embryonic chicken Müllerian duct . 0.05 and highest number of genes involved in the process.

Alternative Polyadenylation in response to temperature stress contributes to gene regulation in Populus trichocarpa

We show that the change of polyA tails is widespread under the temperature stresses, and genes related to RNA metabolism are linked to APA-mediated post-transcriptional regulation. The processing and mapping of PAS-Seq reads for identification of polyA-tail associated sequences. The clean reads of all samples were combined and mapped to the P.

RNA-seq analysis of galaninergic neurons from ventrolateral preoptic nucleus identifies expression changes between sleep and wake

Factors affecting the rapid changes of protein under short-term heat stress

tailieu.vn

More substances were enriched under severe heat stress than under mild stress at both the transcriptional and protein levels, not only increasing the number but also broadening the capability (Fig. 2), transcrip- tion and proteins play regulatory roles in different fields during short-term heat stress. That is to say, ribosome expression under short-term heat stress is free from transcriptional regulation or mRNA returns to undis- turbed levels rapidly after translation..

Transcriptome profiles of sturgeon lateral line electroreceptor and mechanoreceptor during regeneration

The expression and phylogenetic analyses of the key transcriptional regulation related genes. The expression levels of the five genes in AOs are significantly higher than NMs at untreated group, which suggests they could be used to distinguish mature AO and NM (Fig. These two genes were also up- regulated in 12 hpt and 24 hpt in NMs, although they. The expression of ptch1 and tbx18 are lower in AOs and NMs than that in EPs.

Genome-wide identification and expression analysis of the NAC transcription factor family in tomato (Solanum lycopersicum) during aluminum stress

The expression of the acarbose biosynthesis gene cluster in Actinoplanes sp. SE50/110 is dependent on the growth phase

tailieu.vn

This suggests different protein stabilities or post-transcriptional regulation of the Acb proteins, which in turn could indicate bottlenecks in the acarbose biosynthesis. Furthermore, several genes are co-expressed with the acb gene cluster over the course of the cultivation, including eleven transcriptional regulators (e.g. Full list of author information is available at the end of the article. Actinoplanes sp.

Physiological and transcriptomic analyses reveal the roles of secondary metabolism in the adaptive responses of Stylosanthes to manganese toxicity

tailieu.vn

Furthermore, the identified DEGs associated with secondary metabolic pathways suggested that fine-tuned regulation of secondary metabolism might represent an adaptive strategy of stylo to cope with Mn toxicity. In addition, activation of various transcription factors may help stylo to tolerate Mn toxicity through transcriptional regulation.
