Simultaneous quantification of transcripts of the whole bacterial genome allows the analysis of the global transcriptional response under changing conditions. RNA-seq and microarrays are the most used techniques to measure these transcriptomic changes, and both complement each other in transcriptome profiling. In this review, we exhaustively compiled the symbiosis-related transcriptomic reports (microarrays and RNA sequencing) carried out hitherto in rhizobia. This review is specially focused on transcriptomic changes that takes place when five rhizobial species, (=) USDA 110, biovar 3841, CIAT 899, (=) 1021 and HH103, recognize inducing flavonoids, plant-exuded phenolic compounds that activate the biosynthesis and export of Nod factors (NF) in all analysed rhizobia. Interestingly, our global transcriptomic comparison also indicates that each rhizobial species possesses its own arsenal of molecular weapons accompanying the set of NF in order to establish a successful interaction with host legumes.

The effect of LARP7 on gene expression during osteogenesis.
Mol Biol Rep

Institute of Health Sciences, Department of Medical and Surgical Research, Hacettepe University, Ankara, Turkey.
Background: La-related protein 7 (LARP7) is a key regulator of RNA metabolism and is thought to play a role in various cellular processes. LARP7 gene autosomal recessive mutations are the cause of Alazami syndrome, which presents with skeletal abnormalities, intellectual disabilities, and facial dysmorphisms. This study aimed to determine the role of LARP7 in modulating gene expression dynamics during osteogenesis.

Unlabelled: Group A (GAS) is a major human pathogen that causes several invasive diseases including necrotizing fasciitis. The host coagulation cascade initiates fibrin clots to sequester bacteria to prevent dissemination into deeper tissues. GAS, especially skin-tropic bacterial strains, utilize specific virulence factors, plasminogen binding M-protein (PAM) and streptokinase (SK), to manipulate hemostasis and activate plasminogen to cause fibrinolysis and fibrin clot escape.

Glyphosate-based herbicide (GBH), a feed contaminant, has been proven to impair the growth and development of humans and animals. Previous research has revealed that maternal toxin exposure during pregnancy could cause permanent fetal changes by epigenetic modulation. However, there was insufficient evidence of the involvement of DNA methylation in maternal GBH exposure-induced intestinal health of offspring.

Previous studies have demonstrated the safety and efficacy of a live-attenuated glycoprotein G (gG) deletion mutant vaccine strain of ILTV (∆gG-ILTV). In the current study, transcriptional profiles of chicken tracheal organ cultures (TOCs), 24 h post inoculation with ∆gG-ILTV or the gG-expressing parent wild-type strain, CSW-1 ILTV were explored and compared with the mock-infected TOCs using RNA-seq analysis. Transcriptomes of the vaccine and wild-type ILTV were also compared with each other.

Previous studies have demonstrated that one dose of psilocybin leads to persisting neural and behavioral changes. The durability of psilocybin's effects suggests that there are likely alterations of gene expression at the transcriptional level.
