Additions to the Genus (Tubeufiaceae, Tubeufiales) from China with an Identification Key for Taxa.

Helicosporous hyphomycetes is a group of filamentous fungi that shows promising application prospects in metabolizing bioactive natural compounds. During a study of helicosporous fungi in China, six new helicosporous taxa were collected and isolated from decaying wood in Guangxi Zhuang Autonomous Region, China. Morphological comparisons with multi-gene phylogenetic analyses revealed that these six taxa belong to (Tubeufiaceae, Tubeufiales), and they were recognized as three novel species and were named and .

Fungal diversity notes 1512-1610: taxonomic and phylogenetic contributions on genera and species of fungal taxa.

This article is the 14th in the Fungal Diversity Notes series, wherein we report 98 taxa distributed in two phyla, seven classes, 26 orders and 50 families which are described and illustrated. Taxa in this study were collected from Australia, Brazil, Burkina Faso, Chile, China, Cyprus, Egypt, France, French Guiana, India, Indonesia, Italy, Laos, Mexico, Russia, Sri Lanka, Thailand, and Vietnam. There are 59 new taxa, 39 new hosts and new geographical distributions with one new combination.

The effect of the structure of polychlorinated biphenyls on their hydroxylation, oxidation, and glutathionyl conjugation reactions.

Objective: To compare the nature of the metabolites formed from the phase I metabolism (hydroxylation and oxidation) and phase II metabolism (glutathionyl conjugation) of PCBs that have different chlorine substitution patterns. To discuss the structure-activity relationships and metabolic mechanisms of PCBs.

Methods: 4-Cl-biphenyl (PCB3), 4,4'-Cl-biphenyl (PCB15), 3,4,3',4'-Cl-biphenyl (PCB77) were used for in vitro metabolic study.

[Cloning and expression of the pig fast skeletal muscle troponin C gene].

A pig skeletal muscle expressed sequence tag (EST, accession number BM083186) was found to encode amino acid sequences with high homology to human TNNC2. In silico cloning obtained a 843 bp sequence which we named pig fast skeletal troponin C gene (TNNC2). The open reading frame of TNNC2 was between nucleotides 201 - 683, and was confirmed by RT-PCR.

[Identification of differential expression ESTs in pig muscle tissue by DHPLC].

The differential expression ESTs in muscle tissue of Large Yorkshire pig and Lantang pig, one of the local pig breeds in Guangdong province, were identified with DHPLC system and graphic analysis software LabWork4.0, and both methods verified the true differential display bands. The results showed that DHPLC can quickly and accurately detect differential expression mRNA profiles of different tissues, and can be widely used to study mRNA expression, differential expression of different animal tissues under variant environments.
