root rot

Genetic diversity which was determined by the analysis of 16s rdna - rflp and 16s rdna - sequencing were carried out on frankia strains isolated from the root nodules of different actinorhizal plants , including myrica , casuarina , alnus and coriaria . the main results of the research project were as follows 本研究課題對來自楊梅( myrica ) 、木麻黃( casuarina ) 、榿木( alnus )和馬桑( coriaria )的13株frankia菌純培養的16srrna基因進行了pcr - rflp分析和部分菌株的序列測定,初步探討了弗蘭克氏菌的遺傳多樣性和系統發育地位。

The result of numerical taxonomy indicated that there were high phenotypic diversity among the strains isolated from the root nodules of pueraria spp . it can been seen in utilization of carbon and nitrogen sources , antibiotic resistance , resistance to dyes and chemicals , tolerance to acid , acid production , alkali production , nitrate reduction et al . the dendrogram divided all the strains into 數值分類對所有供試菌株進行了131項表型性狀的測定,結果表明,葛藤根瘤菌具有豐富的表型多樣性,表現在利用多種化合物作為唯一碳源、氮源能力,對抗生素、染料和化學藥物的抗性,耐酸性,產酸產堿情況,硝酸還原能力等方面。

10 phenons at the similarity level of 80 % . the fingerprints of rep - pcr which conducted by boxair primer showed that the isolates from the root nodules of pueraria spp . had g reat genetic diversity . they were divided into 11 genetic clusters at the similarity level of 81 % 以boxair為引物的rep - pcr分析結果表明葛藤根瘤菌存在不同水平的遺傳多樣性,在81的相似性水平上,供試葛藤根瘤菌分成了11個遺傳群,其結果證明了慢生葛藤根瘤菌的遺傳多樣性。

First , the morphology , physiology of seed , biological traits , geographic distribution , ecological and community characteristics , karyotypes , nitrogenase activity of root nodules and chemical constituents of e . mollis were reviewed , respectively 本文對翅果油樹的形態特征、種子生理生化、生態學特征、染色體數目、群落生態、生物學特性、固氮生物學以及礦物質和化學成分等方面研究進行了綜述。

Coralloid roots a type of root regularly produced by cycads , which contains symbiotic nitrogen - fixing cyanobacteria in root nodules , giving the roots a knobbly coral - like appearance 珊瑚狀的根:由蘇鐵類植物產生的一種類型的根,根瘤中含有共生的固氮藍細菌,使根形成珊瑚狀的有節的形狀。

Root nodules of the soybean and alfalfa inoculated with xj96077 ( g ) and colony of xj96077 ( g ) were observed using the confocal laser scanning microscope , and the expressions of gfp were detected 而且,通過不同品種的苜蓿、大豆的結瘤試驗,發現xj96077對不同大豆品種的結瘤能力不同。
