[前沿资讯] Indian Tea Industry Demands Government Bailout from Looming Financial Crisis 进入全文

World Tea News 网站

The Indian tea industry is struggling with low prices, high labor costs, vagaries of the weather and with every passing year, the problems are both recurring and amplifying. It was a desperate measure on their side to launch a newspaper advertising campaign on August 1 to draw the government’s attention to this crisis. The advertisement drove home the urgency of the problems faced by the industry, revealing the discrepancy between costs and selling prices, and seeking the government’s intervention.

[学术文献] Endophytic fungi from the branches of Camellia taliensis (W. W. Smith) Melchior, a widely distributed wild tea plant 进入全文

World Journal of Microbiology and Biotechnology 期刊

Camellia taliensis (W. W. Smith) Melchior is a wild tea plant endemic from the west and southwest of Yunnan province of China to the north of Myanmar and is used commonly to produce tea by the local people of its growing areas. Its chemical constituents are closely related to those of C. sinensis var. assamica, a widely cultivated tea plant. In this study, the α diversity and phylogeny of endophytic fungi in the branches of C. taliensis were explored for the first time. A total of 160 fungal strains were obtained and grouped into 42 species from 29 genera, which were identified based on rDNA internal transcribed spacer sequence analysis. Diversity analysis showed that the endophytic fungal community of the branches of C. taliensis had high species richness S (42), Margalef index D′ (8.0785), Shannon–Wiener index H′ (2.8494), Simpson diversity index DS (0.8891), PIE index (0.8947) and evenness Pielou index J (0.7623) but a low dominant index λ (0.1109). By contrast, that in the branches of C. taliensis had abundant species and high species evenness. Diaporthe tectonigena, Acrocalymma sp. and Colletotrichum magnisporum were the dominant endophytic fungi. The phylogenetic tree was established by maximum parsimony analysis, and the 11 orders observed for endophytic fungi belonging to Ascomycota and Basidiomycota were grouped into 4 classes.

[学术文献] A higher-level phylogenetic classification of the Fungi 进入全文

Mycological Research 期刊

A comprehensive phylogenetic classification of the kingdom Fungiis proposed, with reference to recent molecular phylogenetic analyses, and with input from diverse members of the fungal taxonomic community. The classification includes 195 taxa, down to the level of order, of which 16 are described or validated here: Dikarya subkingdom nov.; Chytridiomycota, Neocallimastigomycota phyla nov.; Monoblepharidomycetes, Neocallimastigomycetes class. nov.; Eurotiomycetidae, Lecanoromycetidae, Mycocaliciomycetidae subclass. nov.; Acarosporales, Corticiales, Baeomycetales, Candelariales, Gloeophyllales, Melanosporales, Trechisporales, Umbilicariales ords. nov. The clade containing Ascomycota and Basidiomycota is classified as subkingdom Dikarya, reflecting the putative synapomorphy of dikaryotic hyphae. The most dramatic shifts in the classification relative to previous works concern the groups that have traditionally been included in the Chytridiomycota and Zygomycota. The Chytridiomycota is retained in a restricted sense, with Blastocladiomycota and Neocallimastigomycota representing segregate phyla of flagellated Fungi. Taxa traditionally placed in Zygomycota are distributed among Glomeromycota and several subphyla incertae sedis, including Mucoromycotina, Entomophthoromycotina, Kickxellomycotina, and Zoopagomycotina. Microsporidia are included in the Fungi, but no further subdivision of the group is proposed. Several genera of ‘basal’ Fungi of uncertain position are not placed in any higher taxa, including Basidiobolus, Caulochytrium, Olpidium, and Rozella. 

[学术文献] Developments in fungal taxonomy 进入全文

Clinical Microbiology Reviews 期刊

Fungal infections, especially those caused by opportunistic species, have become substantially more common in recent decades. Numerous species cause human infections, and several new human pathogens are discovered yearly. This situation has created an increasing interest in fungal taxonomy and has led to the development of new methods and approaches to fungal biosystematics which have promoted important practical advances in identification procedures. However; the significance of some data provided by the new approaches is still unclear, and results drawn from such studies may even increase nomenclatural confusion. Analyses of rRNA and rDNA sequences constitute an important complement of the morphological criteria needed to allow clinical fungi to be more easily identified and placed on a single phylogenetic tree Most of the pathogenic fungi so far described belong to the kingdom Fungi; two belong to the kingdom Chromista. Within the Fungi, they ape distributed in three phyla and in 15 orders (Pneumocystidales, Saccharomycetales, Dothideales, Sordariales, Onygenales, Eurotiales, Hypocreales, Ophiostomatales, Microascales, Tremellales, Poriales, Stereales, Agaricales, Schizophyllales, and Ustilaginales).

[学术文献] Analysis of bacterial and fungal communities by Illumina MiSeq platforms and characterization of Aspergillus cristatus in Fuzhuan brick tea 进入全文

LWT - Food Science and Technology 期刊

Fuzhuan brick tea (FBT) is an indigenous dark tea fermented by fungal and bacterial communities, and the special favor of FBT attributes to the actions of microbiota, while the correlation between bacteria and fungi attracts little attention. In the present study, therefore, the compositions of microbial communities in 10 samples of FBT from four tea processing factories were evaluated by Illumina MiSeq sequencing. Bacterial taxonomy analysis revealed that the phylum Firmicutes and Proteobacteria were the predominant bacteria in all samples. Fungal taxonomy analysis revealed that the phylum Ascomycota, family Trichocomaceae, genus Aspergillus was the dominant fungus in all samples. Moreover, Aspergillus (OTU1, OTU2, OTU16, OTU30, OTU31 and OTU37), Wallemia (OTU3), Penicillium(OTU32), Candida (OTU33, OTU35, OTU40 and OTU43), Debaryomyces(OTU48) and Rhodotorula (OTU68) showed higher correlation with bacteria in FBT. Furthermore, a strain Aspergillus cristatus was isolated from FBT, and its morphology and molecular taxonomy were observed and analyzed by scanning electron microscopy and sequencing. Hence, this is the first report to reveal the correlation between bacterial and fungal communities in FBT, and A. cristatus may have potential application to improve the quality of FBT.

[前沿资讯] Emergency Declared in Central China Due to Drought 进入全文

由于严重干旱,包括云南省在内的中国广大茶叶种植区本周有资格获得政府紧急救助。由于异常高温和降雨稀少,中国国家减灾委员会和紧急事务管理部联合宣布湖北省进入四级紧急状态。该宣言涵盖196万英亩(793333公顷)的粮食作物和茶叶。15700名居民无法获得饮用水,还要努力养殖3000多头家畜。6月份以来的降雨量比正常降雨水平低55%,为37毫米。湖北东部与安徽接壤,是一个多山的地区,气候属亚热带,夏季最高气温为24-30℃,平均降雨量为800-1600毫米。而今年湖北的气温稳定在37-39℃。省级气象学家解释说,由于全球变暖和厄尔尼诺现象,使湖北自春季以来降水减少,气温升高。湖北特色茶包括宜红功夫茶、邓村绿茶、五峰毛尖茶及祁门红茶。新华网报道,约358067公顷农作物严重受损,严重干旱已造成16667公顷的农作物死亡。
