Project description:Salmonella enterica variants exhibit diverse host adaptation, outcome of infection, and associated risk to humans. Analysis of 6,335 Salmonella isolates recovered from integrated human-animal surveillance in Emilia Romagna region, Northern Italy, (human population ca 4,500,000), from 2012 to 2017 showed that Salmonella enterica serovar Derby constitutes a swine associated serovar in this epidemiological context while representing also a significant causative agent of human infections. Comparison of the distribution of subtypes of Salmonella Derby from human and swine identified isolates with a distinct PFGE profile that were significantly less isolated in human infections than in swine infections compared to all other subtypes. Here we show that isolates with this PFGE profile form a distinct phylogenetic sub-clade within Salmonella Derby and exhibit a marked reduction in invasion and replication in human epithelial cells but a relatively small reduction in swine epithelial cells, in line with the epidemiological evidence. A single missense mutation in hilD, that encodes the master-regulator of the Salmonella Pathogenicity Island 1 (SPI-1), was identified in this lineage of Salmonella Derby. Since SPI-1 encodes for a primary system of Salmonella invasion into epithelial cells, we investigated the role of the observed mutation in detail. We demonstrated that the missense mutation results in a loss of function of HilD that accounts for the reduced invasion and replication in human epithelial cells while showing a relatively small impact on the interaction with swine cells. This finding is suggestive of a mechanism of invasion alternative to SPI-1 in the Salmonella-swine combination

Project description:In order to screening the responsive miRNAs and target genes of willow under salt stress, the 30-day-old plants were exposed to the salt solution (100 mmol L-1 NaCl) for 0 h and 2 d. then RNA isolated from root and stem tissues for the same time point were mixed respectively in equal amounts for small RNA (sRNA) sequencing. sRNAs with 16–30 nt were separated from 1 µg total RNA by size fractionation. Subsequently, the selected sRNA fragments were ligated with specialized adaptors to the 5’ and 3’ ends (Illumina) using T4 RNA ligase. Then, the ligated RNAs were reverse transcribed and amplified for sequencing using Illumina Hiseq2500 (LC Sciences, Hangzhou, China). Salt stress-responsive miRNAs were identified by comparing the expression levels of miRNAs between the two libraries. Equal amounts of all 2 RNA samples were mixed together to construct one degradome library, and then sent to Hangzhou LC-Bio Co., Ltd (Hangzhou, China) for sequencing by Illumina Genome Analyzer GA-I (Illumina, San Diego, CA, USA).
