Population Dynamics and Survival of Rhizoctonia solani AG-1 in Field Soil Under Rice-Wheat Rotation

Agricultural Sciences in China 2004年第6期3卷 448-455页

作者： lishi-dong SoilborneDiseasesLaboratory BiologicalControlInstituteChineseAcademyofAgriculturalSciencesBeijing100081P.R.China

A field under rice-wheat rotation was selected near Chengdu, China, to study thepopulation of Rhizoctonia solani anastomosis group 1 (AG-1), pathogen causing ricesheath blight disease, in natural soil ecosystem. Inocula of the fungus recovered fromthe field were divided into three types, i.e., sclerotia, free mycelium retained in thesoil passed through a 0.355mm sieve, and colonized plant debris which was subdividedinto small colonized debris retained between 2.00 and 0.355mm sieves and large colonizeddebris retained on 2.00mm sieve after wet screening. Quantitative estimation of thethree types of inocula in one year indicated that small colonized debris was the dominantinoculum type for most of the time. The population peaked in March and September at 1210and 480 colonized debris 100g-1 air-dry soil respectively, and fell down in December andAugust to 0 and 177 colonized debris 100g-1 air-dry soil respectively. Free mycelium wasonly detectable in March, September and October with 1209, 7.9 and 14.5g fresh wtmyceliumg-1 air-dry soil respectively, which corresponded to the two peaks and the secondhighest level of small debris density in the year. Viable sclerotia and large colonizeddebris were rare with populations ranging from 0 to 3 for sclerotia and 0 to 14 for largecolonized debris 100g-1 air-dry soil, but were the main structures to survive overwinter. It was expected that soil temperature was the main factor determining populationdynamics of *** AG-1 in natural soil. Optimum temperature for population increasingis predicted to be around 15℃, with a range from 10 to 25℃. Viability tests indicatedthat 60.9% sclerotia could survive after 265d being buried in natural sandy loam in fieldconditions in Beijing, while colonized rice straw debris (0.5-1.0cm long) could notyield the fungus on medium plates after 88d of being buried under the same conditions.

Mycoparasitism of Gliocladium isolates in China

浙江大学学报（农业与生命科学版） 2004年第4期30卷 412-413页

作者： ZHANGYong-hua MAGui-zhen GAOHui-lan lishi-dong Soil-bornediseasesLab BiologicalControlInst.ChineseAcademyofAgri.Sci.Beijing100081China

During an investigation of mycoparasitic fungi on sclerotia of Sclerotinia sclerotiorum in China, Gliocladium species was consistently encountered and isolated from natural soils collected over the country. Colonization frequencies on sclerotia of S. sclerotiorum by the fungi ranged from 40% to 100% when the sclerotia were introduced into soils and coincubated at 22-24 ℃ for 4 weeks. Identification showed that G. roseum, G. virens and G. catenulatum were the dominant species among the 300 isolates gained. Molecular taxonomy of some Gliocladium isolates analysed by rDNA ITS sequence used ITS1 and ITS4 as primers was demonstrated to be identical with morphological classification. Reinoculation tests by placing surface-sterilized sclerotia onto colony of Gliocladium isolates for 7 days and then surface-sterilized again resulted in 100% sclerotia colonized. Dipping sclerotia with spores suspension of isolates for 5 min and incubated the sclerotia in Petri dishes at 25 ℃ for 24 h resulted in infection of the sclerotia. Microscopic observations indicated that Gliocladium isolates grew along the host hyphae, coiled around, formed appressorium-like structures, penetrated and degraded hyphae of S. sclerotiorum when dual-cultured in slides. Paraffin-section showed that sclerotial tissue collapsed when infected by Gliocladium isolates. Host range test demonstrated that the isolates suppressed hyphal growth of several plant pathogenic fungi, including S. sclerotiorum, Botrytis cinerea, Fusarium oxysporum, Alternaria tenuis, and Rhizoctonia solani. Activities of fungal cell wall degrading enzymes in cultural filtrates and parasitized sclerotia were detected. Results indicated that chitinase and glucanase were important factors involved in the mycoparasitism. A 51 kDa chitinase was isolated and purified from G. catenulatum HL-1-1 culture filtrate. A part of amino acid sequences of the enzyme has been analysed. It was found to have a high homogeneity to chitinase A from Stenotroph

Mycoparasitism of Nematode-Trapping Fungus Monacrosporium ellipsosporumand Its Biochemical Basis

Agricultural Sciences in China 2004年第1期3卷 37-43页

作者： MAGui-zhen lishi-dong XIEBing-yan LUGuo-zhong HebeiNormalUniversityofScience＆Technology Qinhuangdao066004P.R.China BiologicalControlInstitute ChineseAcademyofAgriculturalSciencesBeijing100081P.R.China InstituteofVegetablesandFlowers ChineseAcademyofAgriculturalSciencesBeijing100081P.R.China ShenyangAgriculturalUniversity Shenyang100161P.R.China

Monacrosporium ellipsosporum, a nematode-trapping fungus, was isolated by baiting with sclerotiaof Sclerotinia sclerotiorum in soil from a tobacco field in Yuxi, Yunnan Province. Colonizationfrequency of the sclerotia by the fungus was 18% in natural soil. Reinoculation tests byplacing surface-sterilized sclerotia on fungal cultures for two weeks and then surface-sterilized again led to 32% sclerotia be infected. Dual culture tests in PDA plates did notgive rise to a suppression zone between the colonies of M. ellipsosporum and its counterpartfungi S. sclerotiorum and Rhizoctonia solani, suggesting there was little or no nutritionalcompetition and absent of antifungal compounds. However, M. ellipsosporum could grow overabsent of S. sclerotiorum and R. solani, and significantly inhibited their growth on agarplates. Scanning electron and light microscopic observations showed that hyphae of M. ellipsosporumgrew along and appressed on hypha of S. sclerotiorum and coiled around hyphae of R. *** of cell wall-degrading enzymes showed that M. ellipsosporum grew well in chitin agarmedia, with clear transparent hydrolysis zones. Activities of total chitinase, exo-chitinase,β-1, 3-glucanase and protease were 140.2±11.9, 82.9±4.1, 111.2±7.6 and 76.1±4.3 U respect-ively, after incubation for 4 days at 30 ℃ in liquid media containing ground sclerotia of *** as sole nutrient source. These enzymes might be important in the mycoparasiticactivity of M. ellipsosporum.

Primary endotracheal non-Hodgkin’s lymphoma in a Chinese woman:a case report

Chinese Medical Journal 2005年第8期118卷 702-704页

作者： ZHANGWei-dong lishi-yue OUYANGMing ZHONGNan-shan GuangzhouInstituteofRespiratoryDiseases FirstAffiliatedHospitalofGuangzhouMedicalCollegeGuangzhou510120China

Most patients with non-Hodgkin’s lymphoma (NHL) present with peripheral lymph node enlargement, with or without systemic symptoms. NHL may also involve mediastinal, intra-abdominal and pelvic lymph nodes with resulting symptoms. They may involve only an extranodal site, such as part of the gastrointestinal tract, lung, brain or testis. Extranodal presentation is more common in NHL than in Hodgkin’s disease. Primary endotracheobronchial involvement in non-Hodgkin’s lymphoma is a rare presentation. From 1989 to the present, only 3 cases of primary tracheal NHL were reported in Medline.
