Large-spored Alternaria pathogens in section Porri disentangled. The omnipresent fungal genus Alternaria was recently divided into 24 sections based on molecular and morphological data. Porri is the largest section, containing almost all Alternaria species with medium to large conidia and long beaks, some of which are important plant pathogens e. Alternaria porriA. Porri is the largest section, containing almost all Alternaria species with medium to large conidia doa long beaks, some of which are important plant pathogens.

Our data reveal 63 species, of which 10 are newly described in sect. Porriand 27 species names are synonymised. The three known Alternaria pathogens causing early mpdernidad on tomato all cluster in one clade, and are synonymised under the older name, A.

Modernidad y posmodernidad: coincidencias y diferencias fundamentales

Alternaria protenta, a species formerly only known as pathogen on Helianthus annuus, is also reported to cause early blight of potato, together with A. Two clades with isolates causing purple blotch of onion are confirmed as A. This powmodernidad also found among the pathogens of Passifloraceae, which are reduced from four to three species.

In addition to the known pathogen of sweet potato, A. A new Alternaria section is also described, comprising two large-spored Alternaria species with concatenate conidia. Reinvestigation of foa of porritoxin, a phytotoxin of Alternaria porri. The structure of porritoxin was determined to be 2- 2′-hydroxyethyl methoxymethyl 3′ ‘-methyl-2’ ‘-butenyloxy -2,3-dihydro-1H-isoindolone 1.

Thus our previous proposed structure, 8- 3′,3′-dimethylallyloxy methoxymethyl-1H-3,4-dihydro-2,5-benzoxazocin-6 5H -one 2is incorrect. Purple spot caused by Alternaria porri a major disease in the onion crop in the world. The disease is also widespread in the onion mocernidad in Indonesia. This research aim was to know the effect of mimba leaf Azadirachta indica extract concentration to decrease of Alternaria porri on onion Allium ascalonicum L.

The Temple of San Ignacio de Loyola modernidsd tion to an intention to join the Jesuits of the visual and urban discourse ppsmodernidad this city-ancient bishopric founded by Don Vasco de Quiroga.

With this intention a study is done based on some concepts from the Jesuit architecture and some of the elements of this temple compared to other buildings in the town. Porritoxins, metabolites of Alternaria porrias anti-tumor-promoting active compounds.

To search for possible cancer chemopreventive agents from natural sources, we performed primary screening of moderniidad of Alternaria porri by examining their possible inhibitory effects on Epstein-Barr virus early antigen EBV-EA activation induced by O-tetradecanoylphorbolacetate TPA in Raji cells.

The ethyl acetate extract of A. Three porritoxins were obtained as inhibitory active compounds for EBV-EA from ethyl acetate extract. Inhibitory effect of porritoxin 1 and 2 was superior to that of beta-carotene, a well-known anti-tumor promoter. Furthermore, the structure-activity correlation of porritoxins and their related compounds were discussed. Bulk rock composition and geochemistry of olivine-hosted melt inclusions in the Grey Porri Tuff and selected lavas of the Monte dei Porri volcano, Salina, Aeolian Islands, southern Italy.


The Aeolian Islands are an arcuate chain of submarine seamounts and volcanic islands, lying just north of Sicily in southern Italy. The second largest of the islands, Salina, exhibits a wide range of compositional variation in its erupted products, from basaltic posmoddernidad to rhyolitic pumice.

The Monte dei Porri eruptions occurred between 60 ka and 30 ka, following a period of approximately 60, years of repose. The bulk rock composition of the Monte dei Porri ramando range from basaltic-andesite scoria to andesitic pumice in the Grey Porri Tuff GPTwith the Monte dei Porri posmdernidad having basaltic-andesite compositions. The lava units also contain numerous glomerocrysts, including an unusual variety that contains quartz, K-feldspar and mica.

Melt inclusions MI are ubiquitous in all mineral phases pomodernidad all units of the Monte dei Porri eruptions; however, only data from olivine-hosted MI in the GPT are reported here.

The compositions of most of the MI in the scoriae overlap with bulk rock compositions of the lavas. Analyses of the more evolved mineral phases are required to better constrain the evolution of the magma. Secondary metabolite profiling of Alternaria dauci, A. Chemotaxonomy secondary metabolite profiling has been shown to be of great value in the classification and differentiation in Ascomycota.

However, few studies have investigated the use of metabolite production for classification and identification purposes of plant pathogenic Alternaria species The purpose of the present study was to describe the methodology behind metabolite profiling in chemotaxonomy using A. The results confirmed that A. Purple blotch, caused by Alternaria porri Ellis Cifferi, is a serious disease incurring heavy yield losses in the bulb and seed crop of onion and garlic worldwide.

There is an immediate need for identification of effective resistance sources for use in host resistance breeding. A total of 43 Allium genotypes were screened for purple blotch resistance under field conditions.

In vitro inoculation of a selected set of genotypes with A. In vitro screening of 43 genotypes for resistance to A. An additional 14 genotypes showed consistent moderate resistance in the field as well as in vitro evaluations. Among the related Allium species, A. Differential reaction analysis of three A. All together, the present study suggest that, the newly identified resistance sources can be used as potential donors for ongoing purple blotch resistance breeding program in India.

The role of crop waste and soil in Pseudomonas syringae pathovar porri infection of leek Allium porrum. The roles of post-harvest crop waste and plant invasion from soil in leek plant infection was investigated with the purpose to gain better. Full Text Available Purple spot caused by Alternaria porri a major disease in the onion crop in the world.

The treatment consisted of six levels of Azadirachta indica which is dissolved in one litre of water each treatment.

The number of armandoo are four each treatment. Treatment applied were 0 g plot-1 control; g plot-1; ; g plot-1 ; g plot-1 ; g plot-1 ; g plot The results showed that mimba leaf extract significantly affect the intensity of the purple spot disease and onion production. However, few studies have investigated the use of metabolite production for classification and identification purposes of plant pathogenic Alternaria species.


By using automated chemical image analysis and other multivariate statistic analyses, three sets of species-specific metabolites could be selected, one each for A.
