Different evolutionary histories of two Phragmidium species infecting the same dog rose hosts.
Rust fungi in the genus Phragmidium are frequent pathogens of both wild and cultivated roses. We investigated the occurrence and relationships of rusts on dog roses, Rosa sect. Caninae (Rosa canina, R. corymbifera and R. rubiginosa) in Germany. Two Phragmidium species, P. mucronatum and P. tuberculatum, were able to infect each of the three dog rose species examined. However, the overall infect...
متن کاملMorphological and AFLP-based differentiation within the taxonomical complex section Caninae (subgenus Rosa).
BACKGROUND AND AIMS The taxonomical structure of the polymorphic subgenus Rosa section Caninae is highly complex due to the combination of some unusual features: the unique polyploid chromosomal constitution, the heterogamic canina meiosis, the ability to hybridize interspecifically, and the predominantly matroclinal inheritance. Although most taxonomists agree on the subdivision of the section...
متن کاملAnthocyanins in flowers of genus Rosa, sections Cinnamomeae (=Rosa), Chinenses, Gallicanae and some modern garden roses.
Forty-four taxa of three sections (Cinnamomeae (=Rosa) 26, Chinenses 8 and Gallicanae 10) and eight modern garden roses in the genus Rosa were surveyed for their floral anthocyanins. Eleven anthocyanins: 3-glucosides and 3,5-diglucosides of cyanidin (Cy), pelargonidin (Pg) and peonidin (Pn), 3-rutinosides and 3-rho-coumaroylglucoside-5-glucosides of Cy and Pn, and Cy 3-sophoroside, were isolate...
متن کاملمطالعه ریخت‌شناسی و ریزریخت‌شناسی در بخش Caninae، زیربخش Caninae، Rosa canina L.
در این بررسی، صفات ریخت‌شناسی و ریزریخت‌شناسی در فرم-سری‌های گونه Rosa canina L. مطالعه شد. در این گونه، به علت پراکنش وسیع و پتانسیل بالای هیبریداسیون با سایر گونه‌های این جنس، یافتن صفت ریخت‌شناسی ثابت برای شناسایی آن مشکل است. 30 صفت ریخت‌شناسی و 31 صفت تشریحی و ریزریخت‌شناسی مطالعه شد که با توجه به تنوع زیاد صفات، مخصوصاً چهار صفت: کُرک برگچه، کُرک دمگل، غده برگچه و غده دمگل، این گونه به هشت ف...
متن کاملRoses by other names: taxonomy of the Rhizobiaceae.
When Shakespeare wrote (46), “What’s in a name? that which we call a rose / By any other name would smell as sweet,” he implied that phenotypes (scent in this case) take precedence over nomenclature. In popular usage, they usually do. Cartoonists classify politicians by their ears or noses. Scientists use physical characteristics to delimit everything from species (e.g., cranium size in the gen...
