Identification of orchardgrass (Dactylis glomerata L.) cultivars by using simple sequence repeat markers.
The accurate identification of orchardgrass (Dactylis glomerata L.) cultivars is necessary to ensure purity for consumers, the effective utilization of cultivars, and to protect the intellectual property for breeders. Therefore, this study aimed to use SSR to construct DNA fingerprinting of orchardgrass cultivars. The genetic diversity of 32 orchardgrass cultivars originated from 21 countries, ...
متن کاملFirst Report of Leaf Spot Caused by Alternaria tenuissima on Black Chokeberry (Aronia melanocarpa) in Korea
In July 2015, diseased leaves of black chokeberry (Aronia melanocarpa) were observed in Danyang and Gochang, Korea. The symptoms appeared as circular or irregular brown leaf spots, from which Alternaria tenuissima was isolated. The isolates were cultured on potato dextrose agar, and their morphological characteristics were observed under a light microscope. The colonies were whitish to ash colo...
متن کاملFirst Report of Fusarium subglutinans Causing Leaf Spot Disease on Cymbidium Orchids in Korea
In 2006~2010, leaf spot symptoms, that is, small, yellow spots that turned into dark brown-to-black lesions surrounded by a yellow halo, were observed on Cymbidium spp. in Gongju, Taean, and Gapyeong in Korea. A Fusarium species was continuously isolated from symptomatic leaves; in pathogenicity testing, isolates caused leaf spot symptoms consisting of sunken, dark brown lesions similar to the ...
متن کاملAnalysis of diversity and relationships among orchardgrass (Dactylis glomerata L.) accessions using start codon-targeted markers.
Orchardgrass, or cocksfoot, is an important perennial forage grass worldwide. The comprehensive understanding of orchardgrass accessions will benefit germplasm collection and breeding progress, and it will enhance efforts to improve forage yield and quality. Therefore, 24 novel, simple, polymorphic, and reliable start codon-targeted (SCoT) markers were used to analyze the diversity and genetic ...
متن کاملIn vitro SCREENING FOR RESISTANCE TO PROLINE ANALOGUES IN ORCHARDGRASS Dactylis glomerata L
Plant regeneration capacity of orchardgrass leaf explants cultured in vitro in the presence of 0.01, 0.1, 1.0 and 10.0mM hydroxyproline (Hyp) or azetidin-2-carboxylic acid (A2CA) was determined. Hyp inhibited to a lower extent than A2CA formation of somatic embryos, respectively plants. Hyp also induced relatively insignificant changes of free amino acid content in the leaves of the regenerants...
