AlgR is a key transcriptional regulator required for the expression of multiple virulence factors, including type IV pili and alginate in Pseudomonas aeruginosa. However, regulon molecular regulatory mechanism have yet to be fully elucidated.

Pseudomonas aeruginosa possesses at least three well-defined quorum-sensing (QS) (las, rhl and pqs) systems that control a variety of important functions including virulence. RsaL is QS repressor reduces signal production ensures homeostasis by functioning in opposition to LasR. However, its regulatory role remains elusive. Here, we conducted ChIP-seq assay revealed bound two new targets, the intergenic regions PA2228/PA2229 pqsH/cdpR, which are required for PQS synthesis. Deletion rsaL...

To study the size effects in ferroelectric thin film, we measured optical transmittance and Raman spectra BaTiO3 films deposited by rf-magnetron sputtering technique on fused quartz (111) Si substrates. A variation energy gap peaks with film thickness grain was observed possible origin analyzed.

Three conventional Bayesian approaches (BayesA, BayesB and BayesCπ) have been demonstrated to be powerful in predicting genomic merit for complex traits livestock. A priori, these models assume that the non-zero SNP effects (marginally) follow a t-distribution depending on two fixed hyperparameters, degrees of freedom scale parameters. In this study, we performed prediction Chinese Simmental beef cattle treated parameters as unknown with inappropriate priors. Furthermore, compared modified...

Linkage disequilibrium (LD) plays an important role in genomic selection and mapping quantitative trait loci (QTL). In this study, the pattern of LD effective population size (Ne ) were investigated Chinese beef Simmental cattle. A total 640 bulls genotyped with IlluminaBovinSNP50BeadChip IlluminaBovinHDBeadChip. We estimated for each autosomal chromosome at distance between two random SNPs <0 to 25 kb, 50 100 500 0.5 1 Mb, 5 Mb 10 Mb. The mean values r(2) 0.30, 0.16 0.08, when separation...
