The Effect of Temperature on Spore Germination, Growth and Appressorium Formation of Colletotrichum Gloeosporioides and Dothiorella Aromatica
Conidial germination of Colletotrichum gloeosporioides and Dothiorella aromatica was affected by temperature. The optimal temperature for germination was between 25 and 30°C. No germination occurred at 5 and at 40°C respectively. C. gloeosporioides produced appressoria in vitro while D. aromatica produced long germ tubes without appressoria. Appresorium formation was more sensitive to temperatu...
متن کاملGene Expression Analysis during Conidial Germ Tube and Appressorium Development in Colletotrichum trifolii.
Preinfection development in Colletotrichum spp. exhibits three morphologies (conidia, germ tubes, and appressoria) and is directed by a complex interplay of environmental signals. Germ tube morphogenesis for Colletotrichum trifolii and the related fungus Colletotrichum gloeosporioides f. sp. aeschynomene was shown to be partially dependent on a balance between self-germination inhibitors and en...
متن کاملEffect of Fungicides and Plant Extracts on the Conidial Germination of Colletotrichum gloeosporioides Causing Mango Anthracnose
In Northern Bangladesh, generally mango trees are planted as agroforest that gives higher Net Present Value (NPV) than traditional agriculture. Mango anthracnose caused by Colletotrichum gloeosporioides Penz. is seen as a very destructive and widely distributed disease, which results in poor market value. Five fungicides such as Cupravit, Bavistin, Dithane M-45, Thiovit and Redomil were tested ...
متن کاملInhibition on Conidial Germination of Colletotrichum gloeosporiodes and Pestalotiopsis eugeniae by Bacillus subtilis LB5
The effect of antifungal compound from Bacillus subtilis strain LB5 was tested against conidial germination of Colletotrichum gloeosporioides and Pestalotiopsis eugeniae, causal agent of anthracnose and fruit rot of wax apple, respectively. Observation under scanning electron microscope and light compound microscope revealed that conidial germination was completely inhibited when treated with c...
متن کاملEffect of Crude Extract from Bacillus Subtilis LB5 Cultivated Broth on Conidial Germination of Colletotrichum Gloeosporioides
Bacillus subtilis strain LB5 produced lipopeptide antibiotic iturin A-2 in liquid medium. Crude extract from cell-free supernatant of B. subtilis cultivated broth extracted with n-butanol showed antifungal activity to conidial germination of Colletotrichum gloeosporioides. The germination of conidia was completely inhibited by crude extract. The ultrastructure of conidia after treated with crud...
