cDNA Subtractive Cloning of Genes Expressed during Early Stage of Appressorium Formation by Magnaporthe grisea.
The conidial germ tube of the fungus Magnaporthe grisea differentiates an infection-specific structure, an appressorium, for penetration into the host plant. Formation of the appressorium is also observed on synthetic solid substrata such as polycarbonate. We found that a plant lectin, concanavalin A, specifically suppressed the appressorium formation without affecting the germling adhesion if ...
متن کاملCloning and sequencing of hydroxylase genes involved in taxol biosynthesis.
Two full-length cDNAs (TCH1 and TCH2) were obtained from a cDNA library of Taxus chinensis mainly by the single specific-primer PCR (SSP-PCR) method. Compared with other reported enzymes from Taxus species, the deduced amino acid sequences of TCH1 and TCH2 exhibit significant homologies to hydroxylases that are involved in taxol biosynthesis. These findings imply that the two new genes are clos...
متن کاملCloning and sequencing of chloroperoxidase cDNA.
An oligod-d(T) 12-18 primed cDNA library has been prepared from Caldariomyces fumago mRNA. A clone containing a full-length insert was sequenced on the supercoiled plasmid, pBR322. The complete primary sequence of chloroperoxidase has been derived. We have also determined about 73% of the peptide sequence by amino acid sequencing. The DNA sequence data matches all of the available known peptide...
متن کاملMPG1 Encodes a Fungal Hydrophobin Involved in Surface Interactions during Infection-Related Development of Magnaporthe grisea.
The rice blast fungus expresses a pathogenicity gene, MPG1, during appressorium formation, disease symptom development, and conidiation. The MPG1 gene sequence predicts a small protein belonging to a family of fungal proteins designated hydrophobins. Using random ascospore analysis and genetic complementation, we showed that MPG1 is necessary for infection-related development of Magnaporthe gri...
متن کاملMolecular cloning and characterization of WdPKS1, a gene involved in dihydroxynaphthalene melanin biosynthesis and virulence in Wangiella (Exophiala) dermatitidis.
1,8-Dihydroxynaphthalene (1,8-DHN) is a fungal polyketide that contributes to virulence when polymerized to 1,8-DHN melanin in the cell walls of Wangiella dermatitidis, an agent of phaeohyphomycosis in humans. To begin a genetic analysis of the initial synthetic steps leading to 1,8-DHN melanin biosynthesis, a 772-bp PCR product was amplified from genomic DNA using primers based on conserved re...
