Revision of the genus <Emphasis Type="Italic">Melamphaes</Emphasis> (Melamphaidae): 6. oligo-raker species: <Emphasis Type="Italic">M. papavereus,M. simus,M. hubbsi</Emphasis>

Three oligo-raker species (≤19 rakers on the first gill arch) of the genus Melamphaes have been considered. A new species, M. papavereus, out of the group “M. typhlops” has been described from the Bay of Bengal of the Indian Ocean. M. simus and M. hubbsi out of the group “M. simus” have been revised. M. simus inhabits all oceans between 40° N and 40° S. M. hubbsi has been known from single specimens caught in the central part of the South Atlantic between 11° and 19° S.     

Revision of the genus <Emphasis Type="Italic">Melamphaes</Emphasis> (Melamphaidae). 5. Oligo-raker species: <Emphasis Type="Italic">M. indicus</Emphasis>, <Emphasis Type="Italic">M. eurous</Emphasis>, and <Emphasis Type="Italic">M. typhlops</Emphasis>

Three oligo-raker species (?19 rakers on the first gill arch) of the genus Melamphaes out of the “M. typhlops” group are considered. The validity of M. indicus Ebeling is restored. This species inhabits equatorial and tropical waters of the Indian Ocean and the western part of the Pacific Ocean. M. eurous sp. n., which is related to M. indicus, is described from equatorial waters of the eastern part of the Pacific Ocean. M. typhlops (Lowe) inhabiting the northern part of the Atlantic Ocean, from the equatorial zone about to 45° N, is redescribed.     

Revision of the genus <Emphasis Type="Italic">Melamphaes</Emphasis> (Melamphaidae): 7. oligo-raker species: <Emphasis Type="Italic">M. danae</Emphasis> and <Emphasis Type="Italic">M. pumilis</Emphasis>

Two species, M. danae Ebeling and M. pumilis Ebeling, belonging to the species group “M. simus” are described in the final part of the revision of oligo-raker species of the genus Melamphaes (Melamphaidae) (≤19 gill rakers on the first gill arch). The species M. danae is distributed in the Indian and Pacific oceans between 30° N and 30° S. In the Pacific Ocean, it is known up to 112° W. The species M. pumilis is distributed in the North Atlantic between 17° and 45° N, and the main catches have been conducted in the western part of the ocean. In the eastern part of the ocean, the catches are registered up to 28° W. A key for the identification of 21 oligo-raker species of the genus Melamphaes is presented.     

Revision of genus Melamphaes (Melamphaidae). II. Multi-Raker species: M. polylepis, M. falsidicus sp. nova, M. pachystomus sp. nova, M. macrocephalus, M. leprus

The second part of the publication is devoted to the Melamphaes species (family Melamphaidae), which are characterized by 20 and more rakers on the first gill arch, by seven soft rays in the ventral fin, by absence of a temporal spine, by 14–15 rays in the pectoral fin, and by 11 abdominal vertebrae. M. polylepis is characterized by circumtropical range (Atlantic Ocean, Indian Ocean, western and central Pacific Ocean). Newly described species M. falsidicus is described from the northern Atlantic Ocean, where it was sampled between 34°N and 58°N. Before, this species was defined as M. microps. Another newly described species, M. pachystomus, is described along the Peruvian Coast. M. macrocephalus is redescribed. This species inhabits the eastern tropical Pacific Ocean (approximately between 30°N and 23°S). One of the studied specimens of M. macrocephalus was characterized by larger body size (SL = 128 mm) than was described before for this species. M. leprus is known currently by single findings from the eastern tropical Atlantic Ocean (between 11°N and 4°S). This species was also found in the samples obtain in the Gulf of Guinea.     

Revision of the genus <Emphasis Type="Italic">Melamphaes</Emphasis> (Melamphaidae): Part 3. Multirakered species: <Emphasis Type="Italic">M. suborbitalis,M. parini</Emphasis>, and <Emphasis Type="Italic">M. acanthomus</Emphasis>

In the third part of the revision of the genus Melamphaes Melamphaidae (Melamphaidae), we examine multirakered species (20 and more rakers at the first gill arch) with seven soft rays in the ventral fin that have a posttemporal (temporal) spine directed anteriorly-upwards, with 14–15 rays in the pectoral fin, and 11 (rarely 12) trunk vertebrae. M. suborbitalis inhabits the Atlantic Ocean (in the north up to 57°N, in the south, up to 40°S), the Indian Ocean (is known in its southwestern part), and the western part of the Pacific Ocean. There is no significant evidence on catches of this species in the eastern part of the Pacific Ocean. Apparently, M. suborbitalis is absent in the tropical waters of the oceans. Until recently, M. parini was known from the holotype caught in the Sea of Okhotsk. Two specimens of this rare species: from the central (the area of the Hawaiian Islands) and the northeastern part of the Pacific Ocean are reported. M. acanthomus is an endemic of the eastern part of the Pacific Ocean where it is known along the coasts of America from California to the northern coast of Chile (approximately between 33°N and 21°S).     

<Emphasis Type=Italic>Maireina afibulata</Emphasis> and <Emphasis Type=Italic>M. attenuatipilis</Emphasis>, new members of the cyphelloid genus <Emphasis Type=Italic>Maireina</Emphasis> (Basidiomycota,Agaricomycetes)

Maireina afibulata and M. attenuatipilis are proposed as new members of the recently revised genus Maireina, one of the few anatomically well-studied cyphelloid groups in the Basidiomycota. Maireina species have brownish basidiomes, smooth, parietally unpigmented spores, and are characterized by non-ramified external hyphae with more or less thick, yellow to brown cell walls and distinct crystalline incrustations that always include their distal ends. A key to the species of the genus Maireina is presented, and M. afibulata as well as M. attenuatipilis are described and discussed in detail. Taxonomic novelties: Maireina afibulata Bodensteiner, M. attenuatipilis Bodensteiner     

Revision of genus Melamphaes (Melamphaidae): Part 4. Multi-raker species: M. ebelingi, M. occlusus sp. nova, and M. nikolayi sp. nova

In the fourth part of the revision of the genus Melamphaes (Melamphaidae) multi-raker species (20 and more rakers at the first gill arch, rarely 19??in M. ebelingi) with eight soft rays in the ventral fin are considered. In this species, temporal spine is absent, there are 15 rays in the pectoral fin, and there are 11 to 12 abdominal vertebrae. M. ebelingi inhabits tropical and subtropical waters of the Atlantic Ocean. A new catch of this rare species in the northeastern part of the ocean is reported. The new species M. occlusus is described from one specimen from the subtropical part of the southwestern part of the Indian Ocean. Still another new species, M. nikolayi, is described from one specimen from the northwestern part of the Pacific Ocean (subtropical waters). A table for identification of 15 multi-raker species of the genus Melamphaes is provided.     

The presence of <Emphasis Type=Italic>Zygina</Emphasis> sp. and <Emphasis Type=Italic>Puccinia myrsiphylli</Emphasis> reduces survival and influences oviposition of <Emphasis Type=Italic>Crioceris</Emphasis> sp.

A leaf beetle, Crioceris sp. (Coleoptera: Chrysomelidae), was introduced into Australia as a biological control agent of bridal creeper (Asparagus asparagoides L. Druce) during October 2002. Rearing of Crioceris sp. is labour intensive therefore all releases of Crioceris sp. have been under 1000 individuals, which may be too low to ensure establishment if high mortality and high competition with other agents occurs. The aim of this study is to understand how the presence of two well-established biocontrol agents, a rust fungus (Puccinia myrsiphylli (Thuem) Wint [Basidiomycota: Uredinales]) and a leafhopper (Zygina sp. [Hemiptera: Cicadellidae]), might influence Crioceris sp. establishment. Crioceris sp. neonate larvae were placed on bridal creeper plants with or without the leafhopper and/or rust. The number of larvae that pupated was reduced by 38 and 65% in the presence of the rust fungus and leafhopper, respectively and by 45% in the presence of both agents. As the area infected by the rust increased the area damaged by the leafhopper decreased. The rust appeared to be negatively impacted by the presence of the leafhopper. In a second experiment, female Crioceris sp. adults were given a choice between uninfested bridal creeper plants and those infested with the rust or the leafhopper. The females preferred to lay their eggs on plants without leafhoppers but did not seem to be deterred by the presence of the rust. Consequently, the performance and impact of Crioceris sp. on bridal creeper may be reduced if populations overlap with the other biocontrol agents in the field.     

Distribution of <Emphasis Type=Italic>Hordoindoline</Emphasis> genes in the genus <Emphasis Type=Italic>Hordeum</Emphasis>

Hordoindoline (Hin) genes, which are known to comprise Hina, Hinb-1, and Hinb-2, are associated with grain hardness in barley. However, the interspecific variation in the Hin genes in the genus Hordeum has not been studied in detail. We examined the variation in Hin genes and used it to infer the phylogenetic relationships between the genes found in two H. vulgare subspecies (cultivated barley and H. vulgare subsp. spontaneum) and 10 wild relatives (H. bogdanii, H. brachyantherum, H. bulbosum, H. chilense, H. comosum, H. marinum, H. murinum, H. patagonicum, H. pusillum, and H. roshevitzii). The Hina and Hinb genes of these species were amplified by PCR. We found two Hinb genes in three wild species (H. bogdanii, H. brachyantherum, and H. roshevitzii) and preliminarily named them Hinb-A and Hinb-B. Cluster analysis showed that the 17 Hinb genes present in Hordeum formed two distinct clusters (named A and B). Seven Hinb genes were included in Cluster-A, and 10 Hinb genes were included in Cluster-B. All Hinb-A genes were included in Cluster-A, while all of the Hinb-B genes were included in Cluster-B. In contrast, the Hinb-1 and Hinb-2 genes in H. vulgare were included in Cluster-B. These results suggest that the Hinb genes duplicated during the early stages of diversification in the genus Hordeum. On the other hand, the Hinb-1 and Hinb-2 genes in H. vulgare seem to have been generated by a duplication of the Hinb gene after the split of the lineages leading to H. vulgare and H. bulbosum.     

<Emphasis Type=Italic>Barleria compacta</Emphasis>: a new species in <Emphasis Type=Italic>Barleria</Emphasis> sect. <Emphasis Type=Italic>Prionitis</Emphasis> (Acanthaceae) from Somalia

Following a re-examination of the material treated under Barleria brevispina (Fiori) Hedrén in the recent Flora of Somalia account of the Acanthaceae, it is concluded that two distinct species are involved and Barleria compacta Malombe & I. Darbysh. is described here from north-eastern Somalia. Its affinities and conservation status are discussed.     

<Emphasis Type=Italic>Septoria oleandriicola</Emphasis> sp. nov., a new species from <Emphasis Type=Italic>Nerium oleander</Emphasis> in Turkey

Septoria oleandriicola sp. nov. is described and illustrated from leaves of Nerium oleander, collected in Turkey.     

Karyogenomics of species of the genus <Emphasis Type=Italic>Linum</Emphasis> L.

Using the molecular cytogenetic and RAPD methods of analysis, we studied genomes of 22 cultivated flax varieties and 24 wild species from six sections of the genus Linum L. The chromosome numbers were exactly determined in the karyotypes of all studied species, and all individual chromosomes were identified by the C/DAPI-banding pattern and localization of 26S rDNA and 5S rDNA. B chromosomes were discovered and studied for the first time in species of the section Syllinum Griseb. According to the data obtained, the species studied were divided into eight groups on the basis of similarity of their karyotypes, which corresponded in general to their clustering based on the RAPD results. The systematic positions and phylogenetic relationships of the flax species were verified.     

<Emphasis Type=Italic>Limnobacter humi</Emphasis> sp. nov., a thiosulfate-oxidizing,heterotrophic bacterium isolated from humus soil,and emended description of the genus <Emphasis Type=Italic>Limnobacter</Emphasis> Spring <Emphasis Type=Italic>et al.</Emphasis> 2001

Three Gram-negative, strictly aerobic, chemolithoheterotrophic bacterial strains, designated UCM-30, UCM-33, and UCM-39^T, were isolated in South Korea. Based on their 16S rRNA gene sequences, the three isolated strains were found to be similar to Limnobacter thiooxidans CS-K2^T (97.41–97.68%), Limnobacter litoralis KP1-19^T (95.55–95.76%), and various genera belonging to the class Betaproteobacteria (90.34–93.34%). DNA-DNA hybridization showed 79.3–83.9% similarity between the genomic DNA of UCM-39^T, UCM-30, and UCM-33, while the sequence similarity between UCM-39^T and L. thiooxidans KACC 13837T or L. litoralis LMG 24869T was 23.7% and 18.6%, respectively. The DNA G+C content of UCM 39T was 59.7 mol%, the major ubiquinone was Q-8, and the optimal oxidation rate was observed at 10 mM thiosulfate. The major fatty acids (≥ 10%) were summed features 3 (C_16:1 ω7c and/or C_16:1 ω6c) and 8 (C_18:1 ω7c and/or C_18:1 ω6c), and C_16:0. The major polar lipids (diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol) were found in all members of genus Limnobacter. Based on phenotypic, physiological, and phylogenetic analyses, the UCM-39T strain was found to be significantly distinct to represent a novel species affiliated to the genus Limnobacter. We propose to name it Limnobacter humi sp. nov. with the type strain UCM-39^T (=KACC 18574^T =NBRC 111650^T).     

<Emphasis Type=Italic>Septobasidium parviflorae</Emphasis> sp. nov. on <Emphasis Type=Italic>Pinus parviflora</Emphasis> from Japan

Septobasidium parviflorae sp. nov. on Pinus parviflora is described and illustrated. This species is characterized by its whitish-gray, gray to dark gray-colored fungus body with an indeterminate margin, hyphal strands, and cylindrical basidia with long sterigmata. This is the first report of Septobasidium occurring on a member of the genus Pinus in Japan.     

An endophytic <Emphasis Type=Italic>Neurospora</Emphasis> sp. from <Emphasis Type=Italic>Nothapodytes foetida</Emphasis> producing camptothecin

The medicinal plant, Nothapodytes foetida, contains a number of important alkaloids like camptothecin (an anticancer drug molecule), but its concentration is less to meet the existing demand of this important molecule, in an effort for accessible availability of camptothecin. An endophyte (designated ZP5SE) was isolated from the seed of Nothapodytes foetida and was examined as a potential source of anticancer drug lead compound, i.e., camptothecin, when grown in Sabouraud liquid culture media under shake flask conditions. The presence of an anticancer compound (camptothecin) in this fungus was confirmed by chromatographic and spectroscopic methods in comparison with authentic camptothecin. Isolated endophyte (Neurospora crassa) producing camptothecin may become an easily accessible source for the production of a precursor anticancer drug molecule in the future at a large scale.
