1. The complete chloroplast genome sequence of Vincetoxicum mongolicum (Apocynaceae), a perennial medicinal herb
Abstract Vincetoxicum mongolicum Maxim. (1876), is a perennial medicinal herb, widely distributed in the Loess Plateau of China. Here, we sequenced, assembled, and annotated the complete chloroplast (cp) genome of V. mongolicum, and compared the highly variable gene regions and phylogenetic positions between V. mongolicum and other related species. Results s

2. Molecular epidemiology and antifungal susceptibilities of Aspergillus species isolated from patients with invasive aspergillosis
SUMMARY OBJECTIVE: The aim of this study was to evaluate the demographic data, molecular epidemiology, and in vitro antifungal susceptibility results of patients with Aspergillus isolated from various clinical specimens. METHODS: A total of 44 Aspergillus strains were studied. The definition of invasive aspergillosis in patients was made according to Europ

3. Isolation and molecular characterization of Campylobacter jejuni from chicken and human stool samples in Egypt
Abstract Two hundred broiler chicken samples, 160 laying chicken samples and 75 human stool samples were collected in Egypt. The samples were microbiologically examined, and the C. jejuni isolates were confirmed biochemically and by PCR targeting the mapA gene of C. jejuni. The prevalence of the cadF virulence gene was then determined using PCR. A total of 1

4. FATTY ACIDS ANALYSIS AND CHEMOTAXONOMIC CONSIDERATIONS OF MALVOIDEAE (MALVACEAE) SPECIES
Previous researches showed that fatty acids analysis might be a useful tool to support the taxonomic investigation. In this approach the fatty acids content of ten Malvoideae species was analyzed and its chemotaxonomic significance has been investigated. The aerial parts of the species were collected in the Northeast of Brazil and their fatty acid methyl est

5. Erratum: Population structure and phylogenetic relationships in Brassica rapa L. subspecies by using isozyme markers
RESUMO Objetivou-se avaliar as características estruturais e a produção de forragem do capim-piatã submetido à combinação de duas frequências de corte (95% e máxima interceptação de luz pelo dossel forrageiro, ILmax) e duas alturas pós-corte (15 e 20cm), no período de janeiro de 2012 a março de 2013. O delineamento utilizado foi em blocos ao ac

6. Analysis of the Gene Expression and RNAi-Mediated Knockdown of Chitin Synthase from Leaf-Cutting Ant Atta sexdens
Chitin synthase (CHS) is the enzyme specifically associated with chitin synthesis, an important component of diverse organisms including insects. Two alternative spliced transcripts of the CHS gene (AsCHS-A1 and AsCHS-A2) were identified by quantitative reverse-transcription polymerase chain reaction (RT-qPCR) during the development of the leaf-cutting ant A

7. Two new species of the industrially relevant genus Absidia (Mucorales) from soil of the Brazilian Atlantic Forest
ABSTRACT During a survey of Mucorales in soil from an upland forest area in Pernambuco, Brazil, two specimens were isolated and characterized based on their morphological, physiological, and molecular data (ITS and LSU rDNA). Phylogenetic analyses of the isolates revealed that the strains URM 8209 and URM 8210 are closely related to species of Absidia. URM 8

8. Toward a phylogenetic reclassification of the subfamily Ambavioideae (Annonaceae): establishment of a new subfamily and a new tribe
ABSTRACT A molecular phylogeny of the subfamily Ambavioideae (Annonaceae) was reconstructed using up to eight plastid DNA regions (matK, ndhF, and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH, trnL-trnF, and trnS-trnG intergenic spacers). The results indicate that the subfamily is not monophyletic, with the monotypic genus Meiocarpidium resolved as the seco

9. Isolation, identification and characterization of endophytic fungi of Bambusa oldhamii munro applied as antagonists to Pyricularia oryzae
ABSTRACT Endophytic fungi, in addition to improving plant development, may produce antimicrobial substances that can inhibit pathogens. The objective of this study was to isolate and characterize endophytic fungi of Bambusa oldhamii and evaluate in vitro antagonism to Pyricularia oryzae. Fungal isolates of B. oldhamii shoots were purified and identified by n

10. Phylogenetic placement of Tritirachium strains from the URM culture collection originally founded by Augusto Chaves Batista (1916-1967) in Brazil, and the description of T. batistae sp. nov.
ABSTRACT Twenty-seven Tritirachium strains were present in the URM culture collection originally founded in Brazil by Augusto Chaves Batista. Fifteen freshly-prepared cultures were obtained from these original strains preserved under mineral oil. DNA was extracted for analysing phylogenetic relationships using the sequence information available from Tritirac

11. Fissuroma (Aigialaceae: Pleosporales) appears to be hyperdiverse on Arecaceae: evidence from two new species from southern Thailand
ABSTRACT Thailand and other tropical regions have high fungal diversity. Our investigation and examination of microfungi on palms (Arecaceae) revealed two new ascomycetous species of Fissuroma. Fissuroma arengae and F. wallichiae spp. nov. are introduced using morphological and phylogenetic evidence. The novel species have coriaceous ascomata, cylindrical-cl

12. Psathyrella atlantica (Agaricales: Basidiomycota), a new species from Brazil
ABSTRACT Psathyrella atlantica is described based on material collected in an Atlantic Forest fragment in the state of Pernambuco, Northeast Brazil. It is characterized by slender, whitish and caespitose basidiomata; pileus with orange, small and floccose-squamulose veil remnants; presence of a persistent but fragile-membranous annulus; basidiospores 5-7 ×
