转基因抗虫棉对棉铃虫及其内寄生蜂的双重效应

以含1%转基因（Cry1A+CpTI）抗虫棉“中抗310”棉叶粉的人工饲料为基础,建立一套抗虫棉 棉铃虫Helicoverpa armigera 棉铃虫幼虫内寄生蜂中红侧沟茧蜂Microplitis mediator和棉铃虫齿唇姬蜂Campoletis chlorideae的三级营养关系的研究系统,研究了转基因抗虫棉对棉铃虫及内寄生蜂的双重效应,分析比较了6种状态的棉铃虫生长发育动态,以及寄生蜂的生长状况。结果表明,无论是否被寄生,抗虫棉对棉铃虫生长发育的抑制作用都非常显著;寄生取食抗虫棉饲料的棉铃虫的寄生蜂,其出茧率和茧重都显著下降,对于中红侧沟茧蜂,出茧率和茧重分别下降了26.1%和1.0 mg;对于棉铃虫齿唇姬蜂,分别下降了17.9%和5.1 mg。解剖寄主发现,两种寄生蜂在取食抗虫棉饲料的寄主体内发育缓慢并出现部分畸形幼蜂。棉铃虫幼虫血淋巴总蛋白含量和血淋巴蛋白SDS-PAGE电泳分析表明,取食抗虫棉饲料后,棉铃虫血淋巴总蛋白含量低于相应的对照,推测寄主血淋巴蛋白含量降低是导致寄生蜂生长缓慢、发育不正常的一个重要原因。     

前胡族花粉外壁超微结构及其系统学意义(英文)

Transmission electron microscopy (TEM) observation of pollen grains of 18 species belongingto 18 respective genera of the tribe Peucedaneae Drude revealed distinct ultrastructural difference in thepollen exine, including the thickness and features of rectum, columnar layer, foot layer and endexine. Thesystematic position of those 18 species are re-evaluated based on their ultrastructural characteristics ofpollen exine observed in this study. Seven genera related to Angelica L. in Angelicinae Drude have beendeduced to genus Angelica L. For example, Osterfcum grosseserratum (Maxim.) Kitagawa was changed toAngelica L. by some authors, but it differs from Angelica sinensis (Oliv.) Diels in having well developedtectum which is thicker than the columnar layer and foot layer. Its columnar layer is quite well-developedwith long and branched columellae. Besides its surface is tuberculated. Evidently, its development exceedsthat of Angelica sinensis. However, it is only a moderate evolutional species in its genus, and the Angelicasinensis accounts as the most advanced species in Angelica Diels, thus, placing genus Ostencum Hoffm.in Angelica L is not suitable, it may be more appropriate to keep its original position. In addition, Ferulaakitschkensis B. Fedtsch. ex K.-Pol. differs greatly from those of Talassia transiliensis (Herd.) Korov. andSchumannia turcomnnia Kuntze, because of its very well-developed columnar layer, being about four tofive times thicker than the total of tectum and foot layer, tuberculated tectum surface and complicatedstructure of columnellae. As another species Heracleum forrestJ‘iWolff also differs from Semenovia rubtzovii(Schischk.) Monden. in having an even thickness of exine and well-developed columnar layer, it seemssuitable that they should also be treated as two independent genera.     

盅口族线虫分类系统评述(线虫纲:圆线科)

对盅口族Cyathostominea线虫分类系统的研究进行了回顾和讨论,根据各分类学家的意见,笔者提出了盅口族线虫的分类系统,该系统以Lichtenfels等人（1998）的观点为基础,其不同点在于：1）将马线虫属Caballonema Abulasze,1937和柱咽属Cylindropharynx Leiper,1911从盅口族中移出,放入柱咽族Cylindropharyngea Popova,1952;2)Scialdo-Krecek(1984)描述的Cylicodon-tophorus reineckei应归属于副杯口属Parapoteriostomum Hartwich,1986.

小麦族披碱草属、鹅观草属和猬草属模式种的C带研究

采用改良的Giemsa C带技术,分析了小麦族披碱草属、鹅观草属和猬草属模式种的染色体C带带型。Elymus sibiricus、Roegneria caucasica和Hysrix patula的染色体在Giemsa C带带型上存在明显的差异,显示了这3个属模式种的物种特异性。3个模式种的Giemsa C带核型表明,C带带纹主要分布在染色体的末端和着丝粒附近,而中间带相对较少。对E.sibiricus、R.caucasica和H.patula的St、H、Y染色体组C带带型与其它物种的St、H、Y染色体组C带带型的差异进行了讨论。     

茄科马尿泡和天仙子的花器官发生

利用扫描电镜研究了茄科(Solanaceae)天仙子族(Hyoscyameae)中国特有属马尿泡属( Przewalskia Maxim.)马尿泡( Przewalskia tangutica Maxim.)和天仙子属( Hyoscyamus L.)天仙子( Hyoscyamus niger L.)的花器官发生和发育,研究结果表明:马尿泡和天仙子花器官的发生和发育具有以下3个共同特征:1)符合Hofmeister规律, 即新器官的发生首先出现在花顶已经存在的器官之间;2)花冠的发育模式符合茄科植物所具有的"后合瓣"("late sympetaly")现象,即花瓣单独发生但后来又通过它们基部分生组织的融合而连合起来;3)花被五基数且花器官原基发生顺序为向心发育.但是它们的花萼原基具有不同的发生方式.天仙子花萼裂片原基的发生方式为环状发生;马尿泡花萼裂片原基的发生方式为螺旋状发生,但5个花萼裂片原基在都出现后就连成了一个环.马尿泡是介于天仙子属和山莨菪属之间的类群,它比天仙子属原始但较山莨菪属进化.
