Comparative phylogenetic analysis of vitellogenin in species of cyst and root-knot nematodes

Summary Plant-parasitic nematodes (PPN) are an economically important group of crop pests and oviparous animals; all nutrients required to develop ensure the survival their unhatched progeny need be deposited within egg, including proteins. The most abundant protein is vitellin, formed a precursor vitellogenin, which has roles in transporting lipids, providing amino acids influencing post-embryonic development. genes encoding vitellogenin have been well studied Caenorhabditis elegans , but little known about PPN. Using gene sequences from C. homologous genomes some cyst root-knot were identified hypothetical predicted. Protein domains then determined. Sequences aligned using MUSCLE used construct phylogenetic trees maximum likelihood method. With availability genomic data use online local alignment tools, could PPN genomes. All predicted contained same as ; Vitellogenin_N, open beta-sheet von Willebrand factor domain type D. constructed tree clustered species into four groups: nematodes, two nematode groups species. By determining inferring relationships, this form potential basis understand further role nematodes.
