Virulence and rep-PCR Analysis of Pyricularia grisea Isolates from Two Brazilian Upland Rice Cultivars
The phenotypic and genetic diversity of 77 isolates of Pyricularia grisea collected from two upland rice cultivars, Maravilha and Primavera, was studied. Isolates exhibiting compatible reaction to cv.Primavera were incompatible to cv.Maravilha and vice versa, with the exception of six isolates that were compatible to both cultivars. The virulence of isolates from cv. Maravilha on 32 test genoty...
متن کاملThe Potential of Streptomyces as Biocontrol Agents against the Rice Blast Fungus, Magnaporthe oryzae (Pyricularia oryzae)
Rice is a staple food source for more than three billion people worldwide. However, rice is vulnerable to diseases, the most destructive among them being rice blast, which is caused by the fungus Magnaporthe oryzae (anamorph Pyricularia oryzae). This fungus attacks rice plants at all stages of development, causing annual losses of approximately 10-30% in various rice producing regions. Syntheti...
متن کاملAcquired Tolerance to Blasticidin-S in Pyricularia oryzae
HWANG, B. K., and H. S. CHUNG. 1977. Acquired tolerance to Blasticidin-S in Pyricularia oryzae. Phytopathology 67: 421-424. Thirteen naturally-occurring isolates of Pyricularia oryzae transfers on fungicide-free media. Successive monoconidial varied in tolerance to Blasticidin-S [l-(1'-cytosinyl)-4-[L-3'cultures of Bu7 were genetically homogeneous for tolerance. amino-5-(l"-N-methylguanidino) v...
متن کاملمطالعه ساختار جمعیت Pyricularia grisea جدا شده از برنج بر اساس نشانگر مولکولی rep-PCR و شناسایی گروه‌های سازگاری رویشی
به منظور تعیین تنوع ژنتیکی Pyricularia grisea، 35 جدایه تک اسپور بر اساس انگشت‌نگاری DNA به روش rep-PCR و شناسایی گروه‌های سازگاری رویشی در این تحقیق استفاده شدند. جدایه‌ها در سالهای 1376-1378 از خوشه‌های آلوده به بیماری بلاست مزارع برنج استان گیلان جمع‌آوری گردید. برای تعیین تنوع ژنتیکی و شناسایی دودمان‌های کلونی پراکنده در جمعیت قارچ، از دو آغازگر طراحی شده بر اساس توالی نوکلئوتیدهای قطعه ERI...
متن کاملBiologically-generated primer for PCR: PCR primer of unknown sequence
We describe a method for producing specific PCR primers directly from PCR product, bypassing the usual need to know the primer sequence. Lack of abundance of primers derived from a PCR product is compensated for by the incorporation of an arbitrary 5'TAG sequence which acts as a surrogate template target for the bulk amplification phase. We use the technique to amplify clonospecific rearranged ...
