摘要

从宁波从美国进口火炬松(Pinus taeda)中分离得到一株火炬松Deladenus taedae n. sp。对这一新物种进行了形态学描述、图解和分子表征。食用菌和感染菌均有发现和描述。这个新种，D. taedae n. sp.，类似于一些其他种类的Deladenus，排泄孔位于半裂口的前部。新种的特点是:食菌雌虫的侧场有6条线，尾尖，精囊小，感染雌虫的花柱短。在食菌雌虫中，排泄孔位于前端74 ~ 98 μm和半裂体前端37 ~ 54 μm。扩增部分rDNA 18S、完整内转录间隔段、5.8S和部分28S D2/D3基因并测序。基因的系统发育分析将该新种与所有其他测序的Deladenus物种区分开来。

Deladenus taedae n. sp. (Nematoda: Neotylenchidae) in Loblolly pine (Pinus taeda) woods from USA intercepted in Ningbo, P.R. China

Deladenus taedae n. sp. was isolated from loblolly pine wood (Pinus taeda) intercepted in Ningbo, P.R. China, in imports from the USA. This new species is morphologically described and illustrated and characterised molecularly. Both mycetophagous and infective forms were recovered and described. The new species, D. taedae n. sp., resembles some other species of Deladenus in which the excretory pore is situated anterior to the hemizonid. The new species is characterised by the lateral fields with six lines, pointed tail ending and small spermatheca in mycetophagous females and short stylet in infective females. In mycetophagous females, the excretory pore is 74-98 μm from the anterior end and 37-54 μm anterior to the hemizonid. The partial rDNA 18S, complete internal transcribed spacer, 5.8S and partial 28S D2/D3 genes were amplified and sequenced. Phylogenetic analyses of the genes distinguished this new species from all other sequenced Deladenus species.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
