Metabolites in the fruits of edible plants include sweet sugars, visually appealing pigments, various products with human nutritional value, and biologically active plant hormones. Although quantities of these metabolites vary during fruit development and ripening because of cell division and enlargement, there are few reports describing the actual dynamics of these changes. Therefore, we appli...
Recent evidence indicated that interspecific hybridization was the major mode of evolution in Pyrus. The genetic relationships and origins of the Asian pear are still unclear because of frequent hybrid events, fast radial evolution, and lack of informative data. Here, we developed fluorescent sequence-specific amplification polymorphism (SSAP) markers with lots of informative sites and high pol...
The pear is an important temperate fruit worldwide that is produced by a group of species in the genus Pyrus. Callery pear (Pyrus calleryana Decne) is characterized by high resistance to multiple diseases, good adaptability, and high ornamental value, and is therefore widely planted in pear orchards for edible fruit production or as stock. Plant pathogens are a major threat to pear yield. Black...
Sand pear (Pyrus pyrifolia) russet pericarp is an important trait affecting both the quality and stress tolerance of fruits. This trait is controlled by a relative complex genetic process, with some fundamental biological questions such as how many and which genes are involved in the process remaining elusive. In this study, we explored differentially expressed genes between the russet- and gre...
گونه Pyrus pashia به عنوان گزارشی جدید از شمال شرق ایران گزارش میشود. این گونه با دارا بودن برگهای کم وبیش تخم مرغی شکل و نوک تیز و همچنین اندازه میوه از گونه مجاور خود یعنی P. boissieriana قابل تفکیک می باشد. طرحی از این گیاه در مرحله میوه و گل به همراه نقشه پراکنش و تصاویری از مراحل گلدهی و میوه دهی دو گونه ذکر شده ارائه میگردد.
گونههای Cotoneaster esfandiarii و Pyrus kandevanica به عنوان گونههای جدید نامگذاری و شرح داده میشوند. گونه اولی با گونه P. boissieriana قرابت دارد و نزدیکترین گونه به گونه دومی C. integerrimus است. اختلاف گونههای جدید با گونههای وابسته توضیح داده میشود.
