Project description:Similar to other plant-parasitic nematodes, root lesion nematodes possess an array of enzymes that are involved in degradation of the plant cell wall. Here we report the identification of a gene encoding a cell wall degrading enzyme, pectin methylesterase PME (EC 3.1.1.11), in the root lesion nematode Pratylenchus penetrans. Both genomic and coding sequences of the gene were cloned for this species, showing the presence of four introns that excluded a potential bacterial contamination. Expression of the Pp-pme gene was localized in the esophageal glands of P. penetrans as determined by in situ hybridization. Temporal expression of Pp-pme in planta was validated for early time points of infection. The possible function and activity of the gene were assessed by transient expression of Pp-pme in N. benthamiana plants via a Potato virus X-based vector. To our knowledge, this is the first report on identification and characterization of a PME gene within the phylum Nematoda.
Project description:The CpG depleted Mycoplasma penetrans harbors a CpG specific C5 methyltransferase. The aim of this experiment was to confirm the specificity of the methyltransferase in vivo and in vitro. Genomic DNA from Mycoplasma penetrans and Escherichia coli genomic DNA that either was or was not methylated in vitro by M.MpeI were subjected to Illumina MiSeq bisulfite sequencing.
Project description:Malacoplasma iowae, previously known as "Mycoplasma iowae," is associated with embryo mortality, reduced hatchability, and leg abnormalities in turkeys, leading to considerable economic losses. Here, we report the complete and annotated genome sequence of Malacoplasma iowae type strain 695.
