BACKGROUND Respiratory allergy due to Alternaria is a relevant clinical problem, and specific immunotherapy may represent a viable treatment option. Sublingual immunotherapy (SLIT) is safe and effective, but data for Alternaria are lacking. OBJECTIVE To assess the efficacy of standardized SLIT in patients sensitized to Alternaria in a randomized, prospective, double-blind, placebo-controlled ...

Leaf spot of safflower caused by Alternaria carthami Chowdhury is common in all the safflower growing regions of the world. The disease was reported from India by Chowdhury (1944) and subsequently from erstwhile USSR (Nelen and Vasileva, 1960), United States (United States Department of Agriculture, 1961), Ethiopia and Kenya (Ellis and Holliday, 1970), Africa (Weiss, 1971), Australia (Irwin, 19...

Alternaria brassicae and Alternaria brassicicola are two major phytopathogenic fungi which cause Alternaria blight, a recalcitrant disease on Brassica crops throughout the world, which is highly destructive and responsible for significant yield losses. Since no resistant source is available against Alternaria blight, therefore, efforts have been made in the present study to identify defense ind...

Alternaria brassicicola causes dark spot (or black spot) disease, which is one of the most common and destructive fungal diseases of Brassicaceae spp. worldwide. Here, we report the draft genome sequence of strain Abra43. The assembly comprises 29 scaffolds, with an N50 value of 2.1 Mb. The assembled genome was 31,036,461 bp in length, with a G+C content of 50.85%.

Several 2,6-bis-(un)substituted phenoxymethylpyridines were synthesized and evaluated in vitro against Fusarium graminearum, Helminthosporium sorokinianum, Alternaria brassicae, Alternaria alternata, and Fusarium oxysporum f. sp. vasinfectum. Among all derivatives, compound 3a exhibited a broad-spectrum antifungal activity against the five phytopathogenic fungi.

Alternaria from different Allium plants was characterized by multilocus sequence analysis. Based on sequences of the β-tubulin (BT2b), the Alternaria allergen a1 (Alt a1), and the RNA polymerase II second largest subunit (RPB2) genes and phylogenetic data analysis, isolates were divided into two groups. The two groups were identical to representative isolates of A. porri (EGS48-147) and A. vanu...

Early blight of tomato caused by Alternaria solani, is responsible for severe yield losses in tomato. The conidia survive on soil surface and old dry lower leaves of the plant and spread when suitable climatic conditions are available. Macroclimatic study reveals that highest inoculum concentration of Alternaria spores appeared in May 2012 to 2013 and lowest concentration during January 2012 to...

Two minor components of solanapyrones D and E, phytotoxins from Alternaria solani, were isolated. The absolute stereochemistry of D and the optical purity of solanapyrones A and D were determined by chemical transformation and measurement of the CD spectrum. In addition, complete signal assignment of the (1)H- and (13)C-NMR spectra of solanapyrones A and D, and their solution conformations were...

A leaf blight of carrot (Daucus carota) caused by Alternaria dauci was found in Alentejo (Ourique, Portugal). Morphological characteristics of the fungus are described.
