Three new species of Stemphylium were isolated from diseased leaves of Luffa cylindrica, Lycium chinense and Cucumis melo growing in the Sinkiang province of Northwest China. Stemphylium luffae, S. lycii and S. cucumis are described by morphological and molecular phylogenetic analyses. The principal morphological characteristics of these
three species are congruent with those of Stemphylium. They are distinguished from morphologically similar Stemphylium species based on characteristics of their conidia and conidiophores. In order to establish the molecular phylogenetic status
of these species, DNA loci including the internal transcribed spacer (ITS) nuclear rDNA region and the glyceraldehyde-3-phosphate
dehydrogenase (gpd) genes were amplified and sequenced. Phylogenetic analyses using Maximum-Parsimony (MP) and Neighbor-Joining (NJ) were performed
on the combined DNA sequences of ITS and gpd gene regions. Both morphological observations and molecular analyses support S. luffae, S. lycii and S. cucumis as three new taxa. 相似文献

Four anamorphic fungal species of Heteroconium were collected from tropical and subtropical forests in southern China. Among them, Heteroconium tsoongiodendronis sp. nov. and Heteroconium fici sp. nov. are described from specimens collected on dead branches of Tsoongiodendron odorum and Ficus gibbosa, respectively. Two species of Heteroconium, H. decorosum and H. ponapense, are recorded for the first time in China. A key to Heteroconium and related genera is also provided. 相似文献

Three previously undescribed Solicorynespora species were collected from tropical forests in Hainan Province, China. S. melicopes sp. nov., S. linderae sp. nov. and S. fici sp. nov. are described and illustrated from specimens collected on dead branches of Melicope triphylla, Lindera communis and Ficus auriculata, respectively. They are compared with closely related taxa. A dichotomous key and a synoptic table to Solicorynespora species are provided. 相似文献

A new species of Ulocladium was discovered from diseased leaves of Lycopersicon esculentum and Duchesnea indica from Hunan Province of China. Morphologically, this species is very close to U. consortiale, U. cucurbitae, and U. subcucurbitae in producing narrow ellipsoid conidia at 1–3 days, but the conidial size range of this species at this stage could distinguish it from three well-known species. It also
exhibits the multiplex conidium morphology at the different growth-stages (1–3 days and 4–7 days). The results of maximum
parsimony (MP) and neighbor-joining (NJ) phylogenetic analyses of combined glyceraldehyde-3-phosphate dehydrogenase (gpd) gene and Alternaria alternata major allergen (Alt a 1) genes show that U. solani and U. subcucurbitae cluster in a unique and separate subclade with no clear affinities to a specific sistergroup, and demonstrate that the Ulocladium species group is monphyletic, but two clades of this section are recognized. Morphological features of this new species,
the sequences of the Alt a 1 and gpd gene regions, and its comparison with related species in this genus are discussed. 相似文献

Lomaantha phragmitis sp. nov. is described and illustrated from a specimen collected on dead culms of Phragmites communis in southern China. The fungus differs from other described Lomaantha species in its conidiophores, conidiogenous cells and conidial appendages. Conidial morphology and presence or absence of percurrent proliferation of conidiogenous cells are the main characters distinguishing species within this genus. We provided a key and synoptic table of morphological characters of all three Lomaantha species. 相似文献

This study aimed to develop a bovine mammary epithelial (BME) cell line model, which provides a possibility to determine functional properties of the bovine mammary gland. The primary cell culture was derived from bovine mammary gland tissues and processed enzymatically to obtain cell colonies with epithelial-like morphology. The cultures of BME cells were purified and optimally cultured at 37 °C in DMEM/F12 medium supplemented with 10% fetal bovine serum. The BME cells were identified as epithelial cell line by the evaluating the expression of keratin-18 using immunofluorescence staining. A novel gene expression system strongly enhances the expression of telomerase, has been used to immortalize BME cell line termed hTBME cell line. Interestingly, telomerase remained active even after over 60 passages of hTBME cell line, required for immortalization of BME cells. In addition, the hTBME cell line was continuously subcultured with a spontaneous epithelial-like morphology, with a great proliferation activity, and without evidence of apoptotic and necrotic effects. Further characterization showed that hTBME cell line can be continuously propagated in culture with constant chromosomal features and without tumorigenic properties. Finally, established hTBME cell line was evaluated for mammary gland specific functions. Our results demonstrated that the hTBME cell line was able to retain functional-morphological structure, and functional differentiation by expression of beta (β)-casein as in the bovine mammary gland in vivo. Taken together, our findings suggest that the established hTBME cell line can serve as a valuable tool for the study of bovine mammary gland functions. 相似文献
