The intrinsic protein fluorescence of the polygalacturonase from Colletotrichium lindemuthianum was exploited in stopped-flow experiments aimed at elucidating the kinetic mechanism for this enzyme. Binding of the polymeric substrate polygalacturonic acid (PGA) essentially produced a triphasic fluorescence profile. There was an initial rapid quench in fluorescence, consistent with the rapid form...

Abstract The negative impact of pests on world agriculture is estimated at 1.4 trillion dollars, which 5% the global gross domestic product. In order to save crops lost due agricultural in world, it urgent importance develop effective and fundamentally based control measures against them. this research, main studied were Aphis craccovora Koch; gossypii Glow; Brevicoryne brassicae, Lysiphlebus f...

La antracnosis es una enfermedad causada por el hongo fitopatógeno del género Colletotrichum, que disminuye la calidad y rendimiento aguacate. El objetivo estudio fue determinar actividad antifúngica de D-limoneno, β-citronelol eucaliptol en Colletotrichum acutatum Se realizó aislamiento patógeno, identificaciónmorfológica, molecular mediante técnica (ITS-PCR). Posteriormente, se realizaron pru...

Endopolygalacturonases have been purified from the extracellular enzymes of Colletotrichum lindemuthianum and Aspergillus niger. A protein, purified from Red Kidney (Phaseolus vulgaris) beans for its ability to inhibit the endopolygalacturonase secreted by C. lindemuthianum, inhibits the A. niger endopolygalacturonase almost as efficiently as it inhibits the C. lindemuthianum enzyme.

The coelomycete Colletotrichum gloeosporioides was isolated in pure culture from subcutaneous nodules of the left forearm and elbow of a farmer after traumatic injury. To our knowledge, we report the first case involving this fungus as an etiological agent of subcutaneous infection. The in vitro inhibitory activities of amphotericin B, itraconazole, ketoconazole, miconazole, flucytosine, and fl...

Endophytic fungi are found within the roots of healthy plants, but their function is poorly understood. In this issue, Hiruma et al. demonstrate that, under phosphate-limiting conditions, the endophytic fungus, Colletotrichum tofieldiae, provides growth-promoting and fitness benefits to Arabidopsis, but the plant must restrict fungal growth or risk pathogenesis.

Colletotrichum kahawae is the causal agent of the coffee berry disease, infecting leaves and coffee berries at any stage of their development. Colletotrichum gloeosporioides is the causal agent of brown blight, infecting ripe berries only. Both fungi secrete the same pattern of carboxylesterases to the fermentation broth when cutin is used as carbon source. By using two different strategies com...
