A preliminary study on the production of antibiotic by Streptomyces sp. strain S1 and the possible mechanism it may contribute to the control of diseases caused by oomycetes

open access: yes, 2014
供試鏈黴菌Streptomyces sp. S1菌株為賴氏 (2003) 由市售栽培用泥碳土材料分離獲得,先前研究中已證實其在土壤傳播性真菌或類真菌病原防治用生物殺菌劑發展上確具應用潛力。有關其病害防治應用效果也證實與其優異幾丁質酶與葡萄聚醣分解酶活性所附予之超寄生性、以及所產生二次代謝物的廣效性抗生性有密切關係。本研究旨在針對素具惡名且於世界各地常見造成作物生產嚴重損失之卵菌綱植物病原菌,瞭解此一供試菌株抗生性之作用機制,以為未來推廣應用之參考 ...

Production and characterization of antibiotics by antagonistic Streptomyces spp. strains S1 and S3

open access: yes, 2014
本研究主要目標在探討鏈黴菌Streptomyces sp. S1菌株與Streptomyces griseobrunneus S3菌株所產生之抗生物質的分子與生物特性。此二菌株已知於液態培養下具優異產孢能力,且對多種植物病原真菌具高度之抗生活性並可行超寄生作用,有關其作為微生物殺菌劑的應用潛力已由系列相關試驗成果加以證實。既有研究結果顯示,此二菌株對病原真菌的超寄生作用為其達病害防治效用之重要因子,其中幾丁質水解酶以及葡聚醣水解酶皆已被證實於此超寄生作用中扮演關鍵角色 ...

Photodynamic action of methionine-riboflavin mixture and its application in plant disease control

open access: yes, 2014
甲硫胺酸與核黃素共同存在於光照下,對大部分植物病原真、細菌具有致死的能力, 而這兩種物質普遍存在,不但可做為食品營養成份且為大部分生物生長所必須,並可 以微生物醱酵方式而大量生產。由於這兩種物質並無毒性,因此若施用於田間,應當 無其他藥劑之施用所造成的環境污染、殘毒問題虞慮。在植物病害防治上甚值得開發 利用,本研究主要在探討MR對微生物之殺生作用可能的反應機制,並瞭解MR在植物病

Studies of induced resistance in relation to plant disease control

open access: yes, 2011
植物具有潛在的抗病能力,可被外來因子活化,而在病原侵犯時表現防禦作用,阻礙病原的入侵、繁殖及蔓延,稱為誘導性抗病(induced resistance)。植物誘導抗病性一般在限制性感染、非病原微生物刺激或化學物質刺激的情況下產生。限制性感染時,寄主植物經常形成壞疽病斑,此為表現防禦反應以阻礙病原侵入,同時誘發植物對後續感染的抵抗性,此即所謂的系統性誘導抗病(systemic acquired resistance, SAR)或誘導系統性抗病(induced systemic resistance ...
