The genus Scyliorhinus is part of the family Scyliorhinidae, the most diverse family of sharks and of the subfamily Scyliorhininae along with Cephaloscyllium and Poroderma. This study reviews the phylogenetic relationships of species of Scyliorhinus in the subfamily Scyliorhininae. Specimens of all Scyliorhinus species were examined as well as specimens of four of the 18 species of Cephaloscyllium, two species of Poroderma, representatives of almost all other catshark (scyliorhinid) genera and one proscylliid (Proscyllium habereri). A detailed morphological study, including external and internal morphology, morphometry and meristic data, was performed. From this study, a total of 84 morphological characters were compiled into a data matrix. Parsimony analysis was employed to generate hypotheses of phylogenetic relationships using the TNT 1.1. Proscyllium habereri was used to root the cladogram. The phylogenetic analysis, based on implied weighting (k = 3; 300 replications and 100 trees saved per replication), resulted in three equally most parsimonious cladograms with 233 steps, with a CI of 0.37 and an RI of 0.69. The monophyly of the subfamily Scyliorhininae is supported as well as of the genus Scyliorhinus, which is proposed to be the sister group of Cephaloscyllium. The phylogenetic relationships amongst Scyliorhinus species are presented for the frst time.

AbstractThree species of Plectus Bastian, 1865 viz., P. aquatilis and P. pusillus from Kerman province and P. velox from Alborz province, Iran are described and illustrated. Partial sequences of 18S region of ribosomal DNA gene were amplified for P. aquatilis and P. pusillus. The Blast results of population of P. aquatilis from Iran showed 8–10 nucleotides differences with populations of the same species (AF036602; GQ892827; AY284700) reported from the UK, Belgium and The Netherlands, respectively. Whereas Iranian population of P. pusillus showed 14–16 nucleotides differences with P. cf. pusillus (AY284705; AY284704) reported from The Netherlands. Molecular analysis revealed close relationship of the Iranian plectids with P. cf. parvus (AY284699) reported from The Netherlands. Phylogenetic relationships with other related species in the genus Plectus and closely related genera that are available in the GenBank are given.

The following notes were assembled in arranging the Protarchoides material in the National Collection. In establishing the identity of Protarchoides mellipes (Prov.) it has been found necessary to synonymize one species. A species allied to mellipes is described as new and a table is provided for the separation of the four known North American species. The recording of Trichiosoma as host for a member of this genus is further evidence of the close relationship of the genus with Protarchus Foer.

AbstractTo study the function of the 49 kDa excretory-secretory (ES) protein gene (P49) of Trichinella, the genes was amplified by RT-PCR from RNA of Trichinella spiralis and Trichinella nativa and several Chinese Trichinella isolates of domestic animals, and sequenced after being cloned. The amplified products of these parasites produced bands of about 950 bp. The 97.2 % to 100 % nucleotides identity and 94.3 % to 100 % identity of deduced amino acids among P49 gene of these Trichinella strains showed the close relationship of these parasites. The P49 gene of T. nativa was cloned into the BamHI site of the prokaryotic expression vector pET-30a, and the recombinant vector was expressed. The expressed product was 40.8 kDa in size. In Western blot analysis, the expressed product was reactive to sera of mice infected with T. nativa, T. spiralis and their Chinese geographical strains.

The present review describes the concept of probiotics for plants and analyzes the prospects for using actinomycetes as producers of these drugs. The minimum requirements for plant probiotic microorganisms are proposed, similar to those for human probiotic microorganisms. These are utility, efficiency and safety for plants, as well as mandatory isolation from plant samples. It is noted that these requirements are usually met by endophytic and rhizosphere microorganisms that stimulate plant growth and provide them with protection from phytopathogens. Evidence is given for the possibility of attributing actinomycetes to probiotic plant bacteria, due to the close relationship of these microorganisms with plants, their wide distribution in populations of endophytic and rhizosphere microorganisms, and the presence of phytoregulatory activity. The review provides examples of genera and species of actinomycetes that are promising producers of probiotics for agronomically important crops. The most studied and commercialized of them are representatives of the Streptomyces genus. The current state, prospects and problems in commercialization of probiotics based on actinomycetes are discussed. probiotic microorganisms of plants, associative actinomycetes, endophytes, rhizosphere, biological preparations
