بررسی فیلوژنتیکی گونه های a. raphani ،alternaria arborescens، a. brassisicola و a. alternata با استفاده از توالی its
جنس alternaria یکی از فراوان ترین جنس های قارچی است که در مکان های متنوعی در سراسر دنیا یافت می شود و شامل گونه های بیماری زای گیاهی و پوده زی است که باعث وارد شدن خسارت به بسیاری از گیاهان و یا موجب فساد محصولات کشاورزی پس از برداشت می گردند. میزان خسارت در گونه های بیماریزای گیاهی متغیر است. تعدادی از گونه های این جنس بیماریزای گیاهان بوده و بیماریهای مهم و اقتصادی را در تعدادی ازگیاهان ایجاد...
15 صفحه اولToxigenic profile and AFLP variability of Alternaria alternata and Alternaria infectoria occurring on wheat
The objectives of this study were to evaluate the ability to produce alternariol (AOH), alternariol monomethyl ether (AME) and tenuazonic acid (TA) by A. alternata and A. infectoria strains recovered from wheat kernels obtained from one of the main production area in Argentina; to confirm using AFLPs molecular markers the identify of the isolates up to species level, and to evaluate the intra a...
متن کاملTenuazonic acid production by Alternaria alternata and Alternaria tenuissima isolated from cotton.
Cultures of Alternaria alternata (three isolates) and Alternaria tenuissima (three isolates) obtained from cottonseeds and bolls were toxigenic when cultured on various laboratory media. A mycotoxin was isolated and identified as tenuazonic acid by using solvent partition, thin-layer chromatography, and instrument analyses. Toxicity was monitored with brine shrimp and chicken embryo bioassays. ...
متن کاملProteome Analysis of Pathogen-Responsive Proteins from Apple Leaves Induced by the Alternaria Blotch Alternaria alternata
Understanding the defence mechanisms used by apple leaves against Alternaria alternate pathogen infection is important for breeding purposes. To investigate the ultrastructural differences between leaf tissues of susceptible and resistant seedlings, in vitro inoculation assays and transmission electron microscopy (TEM) analysis were conducted with two different inoculation assays. The results i...
متن کاملMorphological, pathogenic, and molecular characterization of alternaria isolates associated with alternaria late blight of pistachio.
ABSTRACT Alternaria isolates were obtained from various pistachio tissues collected in five orchards in California. For all isolates, morphological characteristics of the colony and sporulation apparatus were determined and compared with those of representative isolates of A. alternata, A. tenuissima, A. arborescens, and A. infectoria. A selection of the pistachio isolates and the representativ...
