中国稻蝗属细胞分类学研究(英文)

本文对分布于中国境内11省区,27个采集地点的八种稻蝗进行了染色体C带核型比较研究。结果表明:中华稻蝗Oxya chinensis,上海稻蝗O.shanghaiensis,无齿稻蝗O.adentata C带分布型式相似,但染色体分组型式、交叉定位数据以及异染色质含量具有差异;山稻蝗O.agauisa具有本身独特的带纹结构,与本属其它种类迥异;双带稻蝗O.bicingula染色体带型结构相似于山稻蝗及中华稻蝗类群,表明三者在进化历程中有一定联系。小稻蝗O.hyla intricata中一个亲缘种团(Sibling species group),体现在种内的形态差异及染色体带型结构的不同。显示该种近期内分化速率较高。据此,本文讨论了稻蝗属内八个种相互间的亲缘关系和分类地位,本文认为稻蝗属内务物种进化速率是不均衡的,这种状态应归因于各物种的遗传背景和环境因素的影响。     

A New Marine Interstitial Ciliate from the Northwest Atlantic Coast Tracheloraphis primitarum Sp. N. (Ciliophora, Kinetofragminophora, Karyorelictida, Trachelocercidae)

ABSTRACT A new species of marine interstitial ciliate, Tracheloraphis primitarum sp. n., is described from intertidal sands (160-200-μm medium grain size) along the Northwest Atlantic coast. Living specimens are not transparent under incident light, 0.4-0.9 mm in length, and are characterized by an elongated body, bulbous anterior and rounded posterior regions. Cytostome is simple without a cleft on the lip. Protargol silver impregnation shows 18-29 longitudinal kineties. The glabrous zone is very narrow, 6-7 μm wide, and corresponds to the area occupied by one kinety and two interkinetal spaces. Ten to fifteen kineties terminate against the glabrous zone. Interkinetal extrusomes are present. The nuclear apparatus is a single centrally-placed nuclear group that consists of three large irregular macronuclei and 2-3 micronuclei; these are either clustered or encapsulated.     

Description and SEM Observations of Meloidogyne sasseri n. sp. (Nematoda: Meloidogynidae), Parasitizing Beachgrasses

Meloidogyne sasseri n. sp. is described and illustrated from American beachgrass (Ammophila breviliffulata) originally collected from Henlopen State Park and Fenwick Island near the Maryland state line in Delaware, United States (6). Its relationship to M. graminis, M. spartinae, and M. californiensis is discussed. Primary distinctive characters of the female perineal pattern were a high to rounded arch with shoulders, widely spaced lateral lines interrupting transverse striations, a sunken vulva and anus, and coarse broken striae around the anal area. Second-stage juvenile body length was 554 μm (470-550), stylet length 14 μm (13-14.5), tail length 93 μm (83-115), tapering to a finely rounded terminus. Male stylet length 20 μm (19-21.5), spicule length 33 μm (30-36). Scanning electron microscope observations provided additional details of perineal patterns and face views of the female, male, and J2 head. Wheat, rice, oat, Ammophila sp., Panicum sp., bermudagrass, zoysiagrass and St. Augustinegrass were tested as hosts. Distribution of the species was the coasts of Delaware and Maryland. The common name "beachgrass root-knot" is proposed for M. sasseri n. sp.
