pathogens such as Colletotrichum lagenarium and Magnaporthe grisea, melanization of appressoria is essential for penetration into the host plant.1) Fungal conidia germinate and the tips of germ tubes differentiate into appressoria, which synthesize melanin. The melanin mediates the buildup of pressure in the appressorium and this high pressure provides the essential driving force for mechanical...
A novel antifungal protein with a molecular mass around 50 kDa was purified from seeds of Sesbania virgata (Cav.) Pers. using ammonium sulfate fractionation followed by gel filtration on a Sephadex G-75 Superfine (Sigma) column and reverse-phase high performance liquid chromatography on a C8 column. The protein, designated FP1-A, with a novel N-terminal sequence AMVHSPGG(S)FS(P), showed growth ...
A case of phaeohyphomycosis is reported in a male renal transplant recipient with a nodular lesion in the right leg who was treated with immunosuppressing drugs. The lesion consisted of a purulent cyst with thick walls. The cyst was excised surgically, and the patient did not receive any antifungal therapy. One year later he remains well. Histological study of the lesion showed a granulomatous ...
Objetivo do trabalho foi verificar a capacidade dos óleos de menta (Mentha sp.), citronela (Cymbopogon nardus L) e capim-limão citratus), os fungicidas tiofanato metílico mancozeb apresentar ação curativa preventiva sobre antracnose (Colletotrichum) em hastes bastão imperador. Foram determinadas Percentagem Inibição Crescimento Micelial (PIC), atividade fungistática funficida essenciais. Poster...
In this study, a novel single-stranded RNA virus was isolated from the plant-pathogenic fungus Colletotrichum higginsianum strain HTC-5, and named “Colletotrichum ssRNA 1” (ChRV1). The complete genome of ChRV1 is 3850 nucleotides in length with GC content 52% contains two in-frame open reading frames (ORFs): ORF1 (smaller) ORF2 (larger). encodes protein highest sequence similarity to proteins e...
Ten newly synthesized organophosphorus derivatives containing substituted chalcones and substituted chalcone semicarbazones were tested for their antifungal efficacy against Colletotrichum falcatum, Fusarium oxysporum, Curvularia pallescens (all sugarcane pathogens). The O,O-diethylphosphate derivatives containing 2-chlorochalcone and 2-chlorochalcone semicarbazone exhibited 70-85% mycelial inh...
Fungal symbionts that live asymptomatically inside plant tissues (endophytes) can influence plant-insect interactions. Recent work has shown that damage by leaf-cutting ants, a major Neotropical defoliator, is reduced to almost half in plants with high densities of endophytes. We investigated changes in the phenotype of leaves that could influence ants' behavior to result in the reduction of fo...
Colletotrichum falcatum, a concealed fungal ascomycete causes red rot, which is a serious disease in sugarcane. It infects economically important stalk tissues, considered as store house of sugar in sugarcane. The study is to find genetic complexities of C. falcatum in establishing this as a stalk infecting pathogen and to decipher the unique lifestyle of this pathogen using NGS technology. We ...
Colletotrichum gloeosporioides from Hevea brasiliensis is the hemibiotrophic fungi which could cause anthracnose in rubber trees. Dicer like proteins (DCL) were the core enzymes for generation of small RNAs. In the present study, the knocking-out mutants of two dicer like proteins encoding genes of C. gloeosporioides were constructed; and functions of two proteins were investigated. The results...
The fungal bean pathogen Colletotrichum lindemuthianum differentiates appressoria in order to penetrate bean tissues. We showed that appressorium development in C. lindemuthianum can be divided into three stages, and we obtained three nonpathogenic strains, including one strain blocked at each developmental stage. H18 was blocked at the appressorium differentiation stage; i.e., no genuine appre...
