多花黑麦草的形态与细胞结构解剖

本研究通过对多花黑麦草 (L olium multiflorum)的植株、花、果的形态特征及种籽的果皮、种皮、胚芽、胚根鞘和盾片的上皮细胞、胚乳的淀粉和糊粉层细胞的组织细胞结构进行鉴别比较和综合分析 ,尤其是对多花黑麦草籽实是否含有与引起同属的毒麦籽实产生毒麦硷 (Temuline- C7H12 N2 O)的类似寄生病菌进行了研究与探讨 ,为口岸杂草检验检疫和牧草的引进、生产提供依据。     

舌蝇共生菌的种系发生及其与宿主在进化上的关系

分析了３个亚属８个种舌蝇的初级内共生菌的１６Ｓ ｒＤＮＡ序列，发现这些初级共生菌属于原细菌的γ－分支并组成其独特的谱系。从３个亚属５个种舌蝇中分离出来的次级共生菌的１６Ｓ ｒＤＮＡ序列几乎完全一致，这些来源不同的细菌是非常相似的，种系发生分析表明它们属于原细菌γ－分支的肠杆菌科，证明不同种舌蝇中的次级内共生菌是舌蝇在种系分化以后独立获得的共生关系。     

胡萝卜施用“禾肥宝”牌酵素菌有机肥的肥效试验

在乌兰县胡萝卜的种植中,进行了“禾肥宝”牌酵素菌有机肥肥效试验。结果表明：“禾肥宝”牌酵素菌有机肥能够促进胡萝卜肉质根长、肉质根横径、单根重的增长,提高产量,对胡萝卜肉质根的裂根率,分叉率影响不大;“禾肥宝”酵素菌有机肥2 600 kg/hm^2是乌兰地区胡萝卜施用酵素菌有机肥的最佳施用量。

浅谈竹荪褐发网菌病害的防治

近年来,武夷山竹荪大面积暴发粘菌-褐发网菌Stemonitis fusca Roth(李玉教授鉴定,以下称褐发网菌),造成严重损失。褐发网菌已成为竹荪栽培的一种严重新病害,但由于褐发网菌是近三四年刚发生的一种新病害,许多菇农对它认识尚不全面,叫法不一,用药也不一。菇农有叫黑孢菌、灰毛菌、黄毛菌,也有叫黑炭菌等。     

Accurate localization and excision of genomic islands in four strains of <Emphasis Type="Italic">Pseudomonas aeruginosa</Emphasis> and <Emphasis Type="Italic">Pseudomonas fluorescens</Emphasis>

Mobile genomic islands (GIs) can be excised from the chromosome, then form a circular intermediate and be reintegrated into the chromosome by the GI internal integrase. Some mobile GIs can also be transferred into a new receptor cell by transformation, conjugation, or transduction. The action sites of the integrase are usually flanked direct repeats (DRs) of the GIs. Accurate localization of the flanking sequences is a precondition for determining the mobility of the GI. Mobile GIs are generally associated with transfer RNAs (tRNAs). Based on the correlation between flanking sequences and tRNA sequences, the flanking sequences of 11 putative mobile GIs in Pseudomonas aeruginosa PAO1, P. aeruginosa PA14, P. fluorescens Pf-5 and P. fluorescens Pf0-1 were identified. Among the 11 GIs, Pf0-1GI-1 is responsible for benzoate degradation. PAO1GI-1, Pf5GI-2, Pf5GI-3, and Pf5GI-4 were confirmed experimentally to be excised from a chromosome to form a circular intermediate. The action sites of the integrases are these GIs direct repeats. Due to distinct DRs, cutting sites for the internal integrase of PAO1GI-1, Pf5GI-2, Pf5GI-3 and Pf5GI-4 were determined outside the T-loop of the tRNA^Gly gene, outside the anticodon loop of the tRNA^Ser gene and tRNA^Lys gene, and at the asymmetric 3′-end of the tRNA^Leu gene, respectively. PAO1GI-1 and other mobile GIs may be transferred into many different strains that belong to different phyla because of the clear flanking sequences. This study describes basic information about the action sites of the integrases, assesses the mobility of GIs, and can help design and transfer mobile GIs to candidate strains.     

种庄稼的动物

秋收冬藏的农蚁北美洲的农蚁非常喜欢一种禾本科植物的种子,这些种子被人们称为"蚁米"。令人惊奇的是,农蚁竟然会种植"蚁米"。农蚁将采集来的蚁米一部分用于储藏,另一部分种植在蚁巢附近直径约为7m的圆形土地上。     

武夷冻茶霉菌菌相分析及优势菌ITSrDNA鉴定

为研究武夷冻茶霉菌的分布情况,采用镜相分析和PCR（polymerase chain reaction）技术对霉菌进行菌相分析及优势菌种鉴定。结果表明,冻茶中主要菌属有曲霉属、毛霉属、根霉属和青霉属,其中青霉属为优势菌属;对随机分离纯化的青霉进行ITSrDNA鉴定,鉴定结果为壳青霉（Penicillium.crustosum Thom）。分析结果可为微生物污染途径分析以及改进冻茶的冷藏工艺条件提供理论依据。
