Draft Genome Sequence of Cercospora cf. sigesbeckiae, a Causal Agent of Cercospora Leaf Blight on Soybean
Cercospora cf. sigesbeckiae is an ascomycete fungal pathogen that infects various plants, including important agricultural commodities, such as soybean. Here, we report the first draft genome sequence and assembly of this pathogen.
متن کاملMore Cercospora Species Infect Soybeans across the Americas than Meets the Eye
Diseases of soybean caused by Cercospora spp. are endemic throughout the world's soybean production regions. Species diversity in the genus Cercospora has been underestimated due to overdependence on morphological characteristics, symptoms, and host associations. Currently, only two species (Cercospora kikuchii and C. sojina) are recognized to infect soybean; C. kikuchii causes Cercospora leaf ...
متن کاملSpecies of Cercospora associated with grey leaf spot of maize
Grey leaf spot is a serious yield-reducing disease of maize (Zea mays) in many parts of the world where this crop is cultivated. The causal organism associated with the disease is Cercospora zeae-maydis. Two potential sibling species have been recognized as Groups I and II. The DNA sequences for the internal transcribed spacers (ITS1 & ITS2), the 5.8S rRNA gene, elongation factor 1-alpha, histo...
متن کاملNew records of anamorphic fungi from North of Iran
Fungi associated with leaf spot symptoms of plants in forest areas of Golestan province, Iran, were collected and examined based on morphological characteristics of conidiophores, conidia and conidiogenous loci. Ten taxa were identified. Among the taxa, Passalora cf. bacilligera and Pseudocladosporium hachijoens are new records for the mycobiota of Iran. Cercospora on Eruca sp. was morphologica...
متن کاملExpression in sugar beet of the introduced cercosporin toxin export (CFP) gene from <Emphasis Type="Italic">Cercospora kikuchii</Emphasis>, the causative organism of purple seed stain in soybean
The Cercospora kikuchii cercosporin export gene, CFP, introduced into Beta vulgaris L. by conjugation with Rhizobium radiobacter, was stably maintained during vegetative propagation as verified by PCR using primers specific for the CFP gene. Transcriptional expression of the CFP gene in leaves was determined by RT-PCR using CFP-specific primers. CFP protein was detected using Western analysis w...
