Study: Effect of the Mbov_0496 mutation on gene expression of Mycoplasma bovis under normal and high potassium conditions
show Abstracthide Abstract
Cyclic di-AMP is an essential and ubiquitous second messenger that regulates bacterial potassium (K+) concentrations to maintain osmotic equilibrium. And its specific K+ regulation mechanism in Mycoplasma has rarely been investigated. We used the ruminant pathogen Mycoplasma bovis (M. bovis) to investigate this mechanism. We verified that MbovP496 is a c-di-AMP synthetase and its mutant T5.415 showed growth inhibition under high K+ condition. To deliver why the mutant strain T5.415 can regulate M. bovis growth, we held a RNA-seq analysis to reveal that the differentially expressed genes between WT and T5.415 under normal condition and high K+ condition. The K+ transport pathways and metabolism related pathways were enriched. In conclusion, we found that the mutation of c-di-AMP synthetase, MbovP496 can broadly influence not only the metal ions transport pathway, but also has an effect on metabolism pathways,which could significantly contribute to understanding the regulation of growth by c-di-AMP synthetase in mycoplasmas. Overall design: RNA-seq profiling of wild-type Mycoplasma bovis and the MbovP496 mutant T5.415 under normal PPLO culture conditions and PPLO medium supplemented with 50 mM K+

Instrument: Illumina NovaSeq 6000
Strategy: RNA-Seq
Source: TRANSCRIPTOMIC
Selection: cDNA
Layout: PAIRED
Construction protocol: Total RNA was isolated using the Trizol Reagent (Invitrogen Life Technologies). Quality and integrity were determined using a NanoDrop spectrophotometer (Thermo Scientific) and a Bioanalyzer 2100 system (Agilent). Zymo-Seq RiboFree Total RNA Library Kit was used to remove rRNA from total RNA. Random oligonucleotides and SuperScript III were used to synthesize the first strand cDNA. Second strand cDNA synthesis was subsequently performed using DNA Polymerase I and RNase H. Remaining overhangs were converted into blunt ends via exonuclease/polymerase activities and the enzymes were removed. After adenylation of the 3′ ends of the DNA fragments, Illumina PE adapter oligonucleotides were ligated to prepare for hybridization. To select cDNA fragments of the preferred 400-500 bp in length, the library fragments were purified using the AMPure XP system (Beckman Coulter, Beverly, CA, USA). DNA fragments with ligated adaptor molecules on both ends were selectively enriched using Illumina PCR Primer Cocktail in a 15 cycle PCR reaction. Products were purified (AMPure XP system) and quantified using the Agilent high sensitivity DNA assay on a Bioanalyzer 2100 system (Agilent). T
