Biocontrol potential of endophytic Penicillium spp. against strawberry anthracnose
بیماری آنتراکنوز توت فرنگی به وسیله‌ی قارچ Colletotrichum nymphaeae ایجاد و یکی از مهمترین بیماریهای توت-فرنگی در استان کردستان است که خسارت قابل توجهی به این محصول وارد می‌کند. در این تحقیق تاثیر قارچ‌های اندوفیت جدا شده از ساقه و طوقه توت فرنگی روی این بیماری بررسی شد. جدایه‌های تاثیرگذار روی بیماری انتخاب و بر اساس روش‌های ریخت شناسی و مولکولی بررسی و سرانجام دو گونه Penicillium hordei و Pen...
متن کاملStrawberry Anthracnose: Histopathology of Colletotrichum acutatum and C. fragariae.
ABSTRACT Ontogeny of the invasion process by Colletotrichum acutatum and C. fragariae was studied on petioles and stolons of the strawberry cultivar Chandler using light and electron microscopy. The invasion of host tissue by each fungal species was similar; however, each invasion event occurred more rapidly with C. fragariae than with C. acutatum. Following cuticular penetration via an appress...
متن کاملPedigree-Based Analysis in a Multiparental Population of Octoploid Strawberry Reveals QTL Alleles Conferring Resistance to Phytophthora cactorum
Understanding the genetic architecture of traits in breeding programs can be critical for making genetic progress. Important factors include the number of loci controlling a trait, allele frequencies at those loci, and allele effects in breeding germplasm. To this end, multiparental populations offer many advantages for quantitative trait locus (QTL) analyses compared to biparental populations....
متن کاملIdentification of colletotrichum species responsible for anthracnose and root necrosis of strawberry in Israel.
ABSTRACT Strawberry anthracnose was observed for the first time in Israel in 1995. The disease reached epidemic proportions in Israeli nurseries and production fields in 1995 and 1996. Using morphological and cultural characteristics, the species responsible for anthracnose was identified as Colletotrichum acutatum. A reliable semi-selective medium, amended with iprodione and lactic acid, was u...
متن کاملNew Insights into the Anthracnose Resistance of Common Bean Landrace
The common bean landrace G 2333 carries a three gene pyramid for anthracnose resistance: Co-4 2 , Co-5 and Co-7. The Co-4 2 gene is well characterized but less information is available on Co-5 and Co-7. The objectives of this study were to determine if a new allele of Co-5 is present in G 2333; to characterize the spectrum of resistance conditioned by the Co-7 gene by deriving lines which only ...
