菌物学报 , 2013,
Abstract: Nectria zangii on Populus is transferred to the newly recovered genus Allantonectria as A. zangii comb. nov. The perithecial anatomy, subcylindrical to cylindric-clavate asci and allantoid to rod-shaped ascospores indicate its close relationship with A. miltina, the type species of Allantonectria. The taxonomic position of this fungus in Allantonectria other than Nectria is also confirmed by the DNA sequence analysis of six loci.

Abstract: DNA molecular markers technique has been introduced as new approaches to study fungal phylogeny and evolution. Nowadays, fungal molecular systematics is a mature discipline, and the history of development and representative research approaches of fungal molecular systematics and the main attributions of these approaches to fungal systematics are discussed in this paper. The organisms studied by mycologists, fungi, are divided into three different groups. The slime moulds and oomycetes do not belong to the Kingdom of Fungi. The recent milestone is the AFTOL (Assembling the Fungal Tree of Life) project, in which a higher-level phylogenetic classification of the Fungi is proposed. The kingdom Fungi traditionally consisted of Ascomycota, Basidiomycota, Chytridiomycota and Zygomycota, but more recent classifications of the fungal kingdom now include Ascomycota, Basidiomycota, Chytridiomycota, Blastocladiomycota, Neocallimastigomycota, Glomeromycota, Microsporidia and several subphyla incertae sedis, including Mucoromycotina, Entomophthoromycotina, Kickxellomycotina and Zoopagomycotina. The concept of the different taxa in fungi has also been revised. Furthermore, the investigation of molecular markers technique influences the fields such as fungal species concept recognition, the connection of teleomorph and anamorph, and molecular fungal ecology, etc.

Abstract: 以盆栽春兰和野生春兰的根为材料,通过切片观察菌根真菌的分布特点和菌根的显微结构.同时采用组织分离方法从盆栽和野生春兰根分别分离得到6个和15个真菌菌株,分离菌株的出现频率分别为16.7%~50%和6.7%~73.3%,并由此判断CGP-3为盆栽春兰菌根的优势菌种,CGW-3为野生春兰菌根的优势菌种.经形态学观察将其初步分为6个分类单元,其中CGP-2和CGW-2分别具有拟日本曲霉(Aspergillus japonicus-like)和拟木霉属(Trichoderma sp.-like)的形态特征.此外,对兰科植物与内生真菌间的专一性进行了讨论.

Abstract: The dominance of gas-vacuolated cyanobacteria is often attributed to their buoyancy and buoyancy in response to environmental conditions. Lake simulator experiments (4 m high and 1 m diameter) and pyrex bottle experiments (10 L) were applied to investigate the buoyancy regulation and vertical distribution of Planktothrix mougeotii in eutrophic lakes at 28 degrees C. During light phase, the filaments stratify in the 2-3 m after 8 h light exposure and the biomass at the layer attach maximum after 12 h light exposure. During dark phase, the filaments are tent to migrate to the surface. 20% of filaments migrate to the surface after 12 h and 50% of filaments migrate to the surface after 48 h. The buoyancy regulation under light condition is that filaments stratify in 10 micromol x (m2 x s)(-1) layers, and the filaments above the layer sink down, while those suspended below the layer float up. The amplitude of diel changes in buoyancy is related to photon irradiance, and the change of buoyancy in light 100 micromol x (m2 x s)(-1)]/ dark is higher than its in light 25 micromol x (m2 x s)(-1)]/ dark. Carbohydrate ballasting may be the only mechanism for buoyancy changes in Planktothrix mougeotii filaments during the period.

Abstract: 通过批量培养实验,测定培养过程中藻的生物量、光合放氧速率及浮力等的变化,研究了2种典型水华蓝藻-水华微囊藻及孟氏浮游蓝丝藻在不同温度下的生长和光合作用特征及浮力调控的机制结果表明,水华微囊藻在温度低于13℃时几乎不能生长,高于16℃能缓慢生长,且随着温度升高,生长速率增大;孟氏浮游蓝丝藻在温度为10℃时就能缓慢生长,当温度高于16℃时即能够较好生长;2种藻的生长速率在10~28℃范围内都随温度升高而增大.2种蓝藻在10℃以上均能进行光合作用,且在实验温度范围内(10~28℃)随温度的升高而增强当温度从28℃转至13℃以下温度培养时,2种蓝藻的浮力下降明显,细胞内伪空胞、糖及蛋白质的变化表明,糖的积累使细胞密度增大是细胞浮力下降的主要原因;在72h之内,水华微囊藻和浮游蓝丝藻细胞内糖含量分别增加了2.2倍和2.5倍,这说明温度降低至13℃以下,水华微囊藻下沉趋于休眠,而孟氏游浮蓝丝藻则趋于底栖继续生长;温度升高至13℃以上,水华微囊藻趋于复苏和上浮,而孟氏浮游蓝丝藻趋于浮游.

Abstract: A new species of Rugonectria, R. sinica, is described based on collections from tropical and subtropical regions of China. Comparisons were made between the new species and a morphologically similar species R. castaneicola. Sequence analysis of the combined ITS and b-tubulin gene of related fungi was also carried out. Both morphological and molecular data support the separation of the Chinese fungus from the Japanese one.

Abstract: 菌寄生属通常寄生于其他真菌子实体上,是子囊菌的重要类群之一,在生物医药和工农业等方面具有经济重要性。简述了菌寄生属在资源与分类、系统发育和寄主专化性等方面的研究现状及进展。已有的分子系统学研究表明,菌寄生属是多谱系类群,形成多个分支,各分支与其无性型特征和寄主种类有关。今后需进一步澄清属种概念,建立稳定的有性阶段-无性阶段对应关系,在全面了解其物种多样性和地理分布特点基础上,深入探讨种间系统发育关系。

菌物学报 , 2013,
Abstract: 长期以来,杆孢赤壳属被视为丛赤壳属的异名,最近才恢复其属级分类地位。臧氏丛赤壳在形态特征上与杆孢赤壳属的模式种Allantonectriamiltina很相似,在子囊壳解剖结构、近圆柱形至柱棒状子囊、腊肠形子囊孢子等方面均表现出共性。二者间形态相似性得到了6个基因序列分析的支持,因而将臧氏丛赤壳转入杆孢赤壳属,建立新组合臧氏杆孢赤壳。

Abstract: DNA分子标记技术为真菌系统进化研究提供了许多新的方法,真菌分子系统学已成为一门成熟的学科。简述了真菌分子系统学的发展简史和代表性的研究方法以及对真菌系统学的主要贡献,包括将广义的真菌划分为3个类群,粘菌和卵菌不再属于真菌界成员。真菌生命之树项目的研究结果对真菌界高阶分类系统作出重大调整,将先前的4个门(壶菌门、接合菌门、子囊菌门和担子菌门)变为7个门(微孢子虫门、壶菌门、新丽鞭毛菌门、芽枝霉门、球囊菌门、子囊菌门和担子菌门)和4个亚门,并对真菌各类群概念作出修订。此外,DNA分子标记技术对真菌种概念的认识、有性型-无性型关联及分子生态学等研究领域产生了重要影响。

Abstract: Genomics that indicates DNA sequence of genomes of different organisms and their genetics background is a core of discipline closely related with biology and medical research. The last decade has witnessed a revolution in the genomics of the fungal kingdom and fungi have become the best model organisms of the eukaryotes. By June of 2008, there were less than 80 fungal genomes that were completely or almost completely sequenced and publicly accessible representing the widest sampling of genomes from any eukaryotic kingdom. These genomes belonging to true fungi, Microsporidia and Oomyces vary in size from approximately 2.5 Mb to 81.5 Mb. This review here provides an overview of available fungal genomes.
