Alternaria brown spot is one of the most important diseases of tangerines and their hybrids worldwide. Recently, outbreaks in Mediterranean areas related to susceptible cultivars, refocused attention on the disease. Twenty representatives were selected from a collection of 180 isolates of Alternaria spp. from citrus leaves and fruit. They were characterized along with reference strains of Alter...

Experiments were carried out to evaluate the antifungal potential of aqueous extracts of leaves, bark, seeds and fruits of Syzygium cumini against two important fungal plant pathogens, Alternaria alternata and Fusarium oxysporum. Results revealed that among various plant parts, aqueous extract of fruit was most effective against the growth of F. oxysporum as compared to other extracts whereas, ...

Tentoxin, a cyclic tetrapeptide produced by several Alternaria species, inhibits the F₁-ATPase activity of chloroplasts, resulting in chlorosis in sensitive plants. In this study, we report two clustered genes, encoding a putative non-ribosome peptide synthetase (NRPS) TES and a cytochrome P450 protein TES1, that are required for tentoxin biosynthesis in Alternaria alternata strain ZJ33, which ...

Carbonyl sulfide (COS) is a new fumigant which has been a potential alternative to methyl bromide and phosphine in many applications. In this study, we investigated the fungitoxicity of COS towards the pathogen of pear black spot disease Alternaria alternata (Fr.) Keissler (A. alternata). Moreover, proteomic analysis and RT-PCR was performed and our results showed that during the fumigation, th...

This paper deals with a case study of conformance testing and interoperability testing of ATM Adaptation Layer type 3/4 (AAL 3/4) implementations. A set of conformance test purposes for AAL 3/4 sublayers is developped. The implementation of these test purposes is analysed using the transverse conformance test method and the interoperability test method. This analysis leads to the identiication ...

The antifungal activity of zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles prepared by bio-safe method was evaluated for Alternaria alternate, Fusarium oxysporum, Rhizopus stolonifer and Mucor plumbeus. It was observed from the study that all the nanoparticles at different concentrations brought about significant inhibition in the germination of spores of Alternaria alternata, Fusarium...

The seed-borne mycoflora of sorghum and foxtail millet collected from different growing areas in South Korea were isolated and taxonomically identified using dry inspection, standard blotter and the agar plate method. We investigated the in vitro and in vivo germination rates of disinfected and non-disinfected seeds of sorghum and foxtail millet using sterilized and unsterilized soil. The perce...

BACKGROUND : Fungal allergens are ubiquitous; however, little progress has been made understanding fungal allergenic material removal from indoor environments. PURPOSE : We investigated removal of environmental allergenic material derived from Alternaria and Cladosporium using sodium hypochlorite in vivo and in vitro. METHODS : Freeze dried allergen extract from Alternaria alternata and Cla...

Alternariosis is a fungal infection usually described in immunodeficient patients. We report a case of cutaneous alternariosis in a renal transplant recipient caused by Alternaria alternata. The patient was treated with intralesional amphothericin B and surgical excision of one non-responding lesion was performed.
