  • Mtxl ( 100 - kilodalton mosquitocidal toxin ) is a kind of toxin synthesized in vegetative growth stage of bacillus sphaericus ( b . s ) . the purified mtxl has the same toxicity as the binary toxin from b . s
    Mtx1 ( 100kdmosquitocidaltoxin )杀蚊毒素是一种在球形芽孢杆菌( bacillussphaericus , b . s )营养体期表达的毒素蛋白,其纯化蛋白对蚊幼的毒力与二元毒素相当。
  • The vegetative status and the flowering and fruiting developmental rhythm of changnienia amoena were investigated in tiantangzhai population of anhui province during the flowering and fruiting period
    摘要对安徽省天堂寨自然保护区独花兰野生种群的花果期节律和营养体状态研究表明,开花植株占观察样本的37 . 5 % ,个体是否开花与假鳞茎数目、地下茎总体积和叶面积呈极显著相关关系。
  • When inadequate n was added , the chloroplast structure in mesophyll cell was damaged in ear leaf , the amount of carbohydrate decreased in mestome sheath , and excessive n - redistribution and n - transportation to grain from vegetative mass appeared , which resulted in earlier leaf senescence . excessive n application led to too high activity of nitrate reductase , excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf , which resulted in the lack of enough carbohydrate in the lower leaf , meanwhile , the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed , which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf , then the early senescence occured
    氮肥用量不足导致穗叶叶肉细胞叶绿体结构性差,维管束鞘细胞碳水化合物累积减少,营养体氮素再分配率大而引起叶片早衰;而过量供氮则导致生长后期硝酸还原酶活性过高,氮素代谢过旺,消耗了大量碳水化合物,以致下位叶不能得到充足的碳水化合物供应而提早脱落,同时叶肉细胞叶绿体片层结构膨胀,呈“肉汁化”特征,维管束鞘细胞淀粉粒大量消耗,无核淀粉粒出现,从而叶片叶绿素含量下降,光合能力降低而出现早衰。
  • Israelensis recombinants , which contained recombinants plasmid pmt4 and pmt9 respectively , were obtained by electroporation . the bioassay results showed that the recombinants b - pmt9 and b - pmt4 had toxicities both to resistant and susceptible c . quinqnefasciatus larvae during vegetative growth stage , having the lc ? o values similar to that of . fi . sssii - 1 . however , the toxic levels of the final sporulated cultures of recombinants b - pmt4 and b - pmt9 differed , with a lcso value of 2 49mg / ml for b - pmt9 and little toxicity for b - pmt4 by using the plasmid pmt9 , m txl gene from b . sphaericus was ligated with p20 and cytjaa gene , giving recombinant plasmid pmpx2
    含有pmt9和pmt4的大肠杆菌转化子能表达产生mtx1毒素,发酵液对敏感和抗性致倦库蚊幼虫具有中度毒杀作用;含有pmt9和pmt4的苏云金芽孢杆菌转化子b - pmt9和b - pmt4在营养体生长阶段对敏感蚊幼和抗性幼虫也具有毒性,毒力与野生型b . sss - 1相当,而不同转化子在芽孢形成期的毒力因插入的mtx1基因转录方向不同而表现出差异,其中b - pmt4对目标蚊幼毒力极低( lc _ ( 50 ) 10mg ml ) ,而b - pmt9对蚊幼虫具有毒性( lc _ ( 50 ) = 2 . 49mg ml ) 。
  • High performance ion exchange chromatography was applied in studying qualitatively and quantitatively of bacteria , which was shown as follows : firstly , physio - biochemical characteristics of bacteria was investigated by ion exchange chromatography . for the first time spores and nutrient of bacillus pumilus had been separated successfully by chromatography . chromatographial behaviors of bacteria at different cultivating environment and different growth phase were also studied
    本文利用高效液相离子交换色谱系统研究细菌学,探讨了该方法在细菌定性、定量方面的应用,主要包括三个方面:首先,利用离子交换色谱系统表征细菌生理、生态方面的变化,首次成功地在色谱上区分了短小芽孢杆菌的芽孢及营养体;考察了不同的培养环境对细菌色谱行为的影响及不同生长阶段的细菌的色谱行为。
  • 2 comparative study on morphology in the light of the form of the materials , hup shows more approximate relationship with gri : they are 50 ~ 70cm high at the period of fructescence ; both are perennials and reproduce themselves by root stock , and especially , hup can also reproduce itself by branch roots and buds growing from stipes when the stems fall againt the ground , and then those buds develop into new bodies ; while gri can reproduce itself not only by vegetative propagation but by seeds . both of hup and gri characterize with bigger leaf blade and with the approximate form of simple leaf , with root stock , and with two - line seeds in one fruit
    2形态学比较从形态上来看,新种hup与分布海拔高度相近的gri比较接近:植株体高大,果期株高50一7ocm ;都为多年生,能以其根状茎繁殖,但前者还以较为特殊的营养体繁殖后代,即倒伏后每个茎节上长出新的根和芽,发育成独立的新植株,后者既能以营养体繁殖,又可通过种子繁殖;具有较大的叶片且单叶形态相近,果实内有二行种子(其它种为一行) . 。
