Project description:Retrons are bacterial genetic elements that encode a reverse transcriptase and, in combination with toxic effector proteins, can serve as antiphage defense systems. However, the mechanisms of action of most retron effectors, and how phages evade retrons, are not well understood. Here, we show that some phages can evade retrons and other defense systems by producing specific tRNAs. We find that expression of retron-Eco7 effector proteins (PtuA and PtuB) leads to degradation of tRNA-Tyr and abortive infection. The genomes of T5 phages that evade retron-Eco7 include a tRNA-rich region, including a highly expressed tRNA-Tyr gene, which confers protection against retron-Eco7. Furthermore, we show that other phages (T1, T7) can use a similar strategy, expressing a tRNA-Lys, to counteract a tRNA anticodon defense system (PrrC170).

Project description:ABA deficient mutant Osaba1-1 exhibits great resistance to Xanthomonas oryzae pv. oryzae (Xoo) infection. To investigate gene expression profile changes at whole genome level between Osaba1-1 and wild-type (Nipponbare) rice during Xoo infection, we employed microarray expression profiling as a discovery platform.

Project description:ϕXacN1 is a novel jumbo myovirus infecting the causative agent of Asian citrus canker, Xanthomonas citri. Its linear 384,670 bp double-stranded DNA genome encodes 592 predicted protein coding genes and shows 65,875 bp direct terminal repeats (DTRs), so far the longest DTRs among sequence phage genomes. The DTRs harbor 56 tRNA genes, corresponding to all 20 amino acids. This is the highest number of tRNA genes reported in a phage genome. Codon usage analyses revealed a propensity that the phage encoded tRNAs target codons that are highly used by the phage but less frequently by its host. The existence of these tRNA genes, additional seven translation-related genes as well as a chaperonin gene found in the ϕXacN1 genome suggests an increased level of independence of phage replication on host molecular machinery and a wide host range. Consistently, ϕXacN1 showed a wider host range than other X. citri phages in an infection test against a panel of X. citri strains. Phylogenetic analyses revealed a clade of phages composed of ϕXacN1 and ten other jumbo phages showing an evolutionary stability in their large genome sizes.

Project description:Xanthomonas campestris pv. campestris (Xcc) is a major bacterial pathogen of cruciferous plants worldwide. The pathogen produces polysaccharides including extracellular cyclic glucan, xanthan, and extracellular enzymes that are key virulence factors. Different Xcc mutants (8397-defective in xanthan and 8523- defective in extracellular glucans) have been obtained and characterized in previously, wich shown to be less infective than the wild type strain when inoculated in N.benthamiana, wich has shown to be an excellent model for the study of Xcc-plant interaction. The objective of this work is evaluate this compounds functions in the plant-pathogen interaction, in particular in the plant transcriptoma modulation to confer susceptibility or resistance to the infection. Plant gene expression profiles would be obtained from independently inoculated leaves of N.benthamiana with the following strains of xanthomonas: Xcc. 8004 (wild type), Xcc. 8397 (xanthan minus), Xcc. 8523 (glucan minus), ant water (control). Leaves discs will be collected at 24 hs post infection and immediately submerged in liquid N2. Total RNA will be extracted with plant RNA specific kits (RNA easy QIAGen), treated with DNase, purified and quantified. Keywords: Reference design

Project description:Transcription profiling of the DSF regulon in Xanthomonas oryzae pv. oryzae (Xoo) using wild type and the rpfF mutant. Cell-cell signaling mediated by the quorum sensing molecule known as Diffusible Signaling factor (DSF) is required for virulence of Xanthomonas group of plant pathogens. DSF in different Xanthomonas and the closely related plant pathogen Xylella fastidiosa regulates diverse traits in a strain specific manner. The transcriptional profiling performed in this study is to elucidate the traits regulated by DSF from the Indian isolate of Xanthomonas oryzae pv. oryzae, which exhibits traits very different from other Xanthomonas group of plant pathogen. In this study, transcription analysis was done between a wild type Xanthomonas oryzae pv. oryzae strain and an isogenic strain that has a mutation in the DSF biosynthetic gene rpfF.

Project description:Prokaryotic proteins must be deformylated before the removal of their first methionine. Peptide deformylase (PDF) is indispensable and guarantees this cotranslational mechanism. Recent genome sequencing and annotation studies highlighted over 2x104 putative peptide deformylase sequences. Furthermore, unpredicted modified bacterial PDF genes have been retrieved from many phages. Sequence comparisons with other known PDFs reveal that viral PDFs are devoid of the key ribosome-interacting C-terminal region. Little is known regarding these viral PDFs, including the capacity of the corresponding encoded proteins to ensure deformylase activity in vitro or in vivo. This investigation determines the activity of the recombinant Vp16 PDF in E. coli PDF defective cell to remove the N-formyl group at the protein N-terminus.
