Symptom expression of Camellia oleifera Abel. artificially inoculated with a spore suspension of Colletotrichum camelliae Massee revealed that the pathogen elaborated a potent toxin. Shaking flask cultures inocu- lated with Colletotrichum camelliae either as spores or mycelial suspensions indicated the presence of an extremely active toxin. The toxin caused a loss of leaf turgor, leaf curl and wilt as well as chlorophyll paling on the tomato seedling at concentration as low as 16 μg/ml. These symptoos were similar...

Symptom expression of Camellia oleifera Abel. artificially inoculated with a spore suspension of Colletotrichum camelliae Massee revealed that the pathogen elaborated a potent toxin. Shaking flask cultures inocu- lated with Colletotrichum camelliae either as spores or mycelial suspensions indicated the presence of an extremely active toxin. The toxin caused a loss of leaf turgor, leaf curl and wilt as well as chlorophyll paling on the tomato seedling at concentration as low as 16 μg/ml. These symptoos were similar to those elicited by the toxin on the host plant. The toxin induced a lesion spot on host leaf at concentration as low as 20 μg/ml glu. eq.A series of experiments indicated that the toxin is water soluble, insoluble in organic solvents, non-dializable, and high in molecular weight. Chemical analyses suggested that the toxin is largely a polysaccharide as it exhibits a positive Molish reaction, when hydrolysed to monosaccharides, and stable at 115℃ for 30' and in pH extremes. The phytotoxic substance was isolated with acetone and partially purified via procedures of gel filtrate and ion exchange chromatography. Partially purified toxin contained about 1.5% protein, the protein was not necessary for toxic activity. The toxic activity was somewhat reduced by periodate treatment, however its molecular weight does not deer crease. Finally the mode of this polysaccharide toxin on plants discussed in some details.

普通油茶炭疽病菌Colletotrichum camelliae Massee在Czapek-Dox培养液中振荡培养时分泌出毒素,这种毒素能够使蕃茄幼苗发生萎蔫,叶片卷缘、干缩和坏死,使茎杆腐烂,能引起寄主油茶叶片发生浸渍状坏死斑。C.camelliae素溶于水,不溶于有机溶剂,对热是稳定的,不可透析的,对α-萘酚试验显阳性,酸水解能使其丧失毒害,水解产物Fehling反应显阳性。一系列试验表明C.camelliae毒素显系为多聚糖类物质。经丙酮沉淀、凝胶过滤、离子交换层析等程序将C.camelliae毒素分离和纯化,单糖分析表明C.camelliae毒素由葡萄糖、半乳糖、甘露糖组成。高碘酸氧化处理可使其毒性减弱,胰蛋白酶、高压蒸煮和极端pH都不改变其毒性效力。

The factors influencing the determinaton of phenols by 4-AAP coloremetrywere reexamined with nearly 20 kinds of phenols. The method was very sensitive at pH 8.0, but the optimumal pH was 9-11 for determination since theblank values were much smaller and more reproducible than at pH 8.0. 17different phenols were tested with 4-AAP, and it was found that nitrophenolsdid not react with it. The values of ε and E~1_λ% of the others were also reported, and the largest difference between them was almost 100-fold. The...

The factors influencing the determinaton of phenols by 4-AAP coloremetrywere reexamined with nearly 20 kinds of phenols. The method was very sensitive at pH 8.0, but the optimumal pH was 9-11 for determination since theblank values were much smaller and more reproducible than at pH 8.0. 17different phenols were tested with 4-AAP, and it was found that nitrophenolsdid not react with it. The values of ε and E~1_λ% of the others were also reported, and the largest difference between them was almost 100-fold. The distillation rate was. tested with 10 phenols. All but 4 could be distilled with water steam, and the distillation volume was almost the same as that of the original samples. Interference caused by aniline could be alleviated by distillation. The phenols whose para position was occupied by-OH, -G1, -GH3, and-NH_2 reacted with 4-AAP. More investigation is needed to explain this phenomenon

用近20种酚重新考察了影响4—AAP比色法的因素。方法在pH8.0下最灵敏,但最佳测试pH为9~11,因为空白值在pH9—11时比pH8.0下小而且重现性好。用17种酚试验了与4—AAP的反应,发现硝基酚类不与4—AAP反应。还报告了其他酚类的ε和E_λ~(1%)值,它们中相差最大的约为100倍,用10种酚试验了馏出速率,除4种酚外所有的酚均可随水蒸汽蒸出,只要馏出体积几乎与原样体积相同。蒸馏可减缓苯胺产生的干扰,对位为-OH,-C1,-CH_3,-NH_2的酚类仍可与4—AAP显色,其解释有待于进一步研究。

Recently, we isolated a non-occluded virus from spontaneous mortal Periplaneta fuliginosa(Serville). The virus suspension was mixed in sterile food to feed healthy P. fuliginosa nymphs(of 154—169 days). The percent mortality of the nymphs which died with infected virus was over 98%. Under electronmicroscope the virus was isometric particle about 23nm in diameter.

Recently, we isolated a non-occluded virus from spontaneous mortal Periplaneta fuliginosa(Serville). The virus suspension was mixed in sterile food to feed healthy P. fuliginosa nymphs(of 154—169 days). The percent mortality of the nymphs which died with infected virus was over 98%. Under electronmicroscope the virus was isometric particle about 23nm in diameter. The ultraviolet absorption of the virus was as character as nucleoprotein Purified virus suspension was used to distinguish the nucleic acid kinds of virus. The results of tests, which were diphenylamine-orcinol test, nuclease digestion, acridine orange staining and reaction with formaldehyde, proved that the virus contained single strand DNA. According to above properties, the virus is Similar to Densovirus in a way.

从黑胸大蠊(Periplaneta fuliginosa)自然罹病的虫尸中分离得到一株非包涵体病毒。将病毒悬液均匀拌入无菌饲料并供食154~169日龄黑胸大蠊健康若虫时,能使其感染、发病,死亡率可达98%以上。在电子显微镜下观察时,病毒为球形二十面体颗粒,直径约23nm。病毒悬液具有典型核蛋白紫外吸收光谱。病毒用DNase和RNase处理并经吖啶橙染色、二苯胺和苔黑酚试验及甲醛反应证明:该病毒含有单链DNA。以上特性与细小病毒科的特征有点类似。
