Cultured pear (Pyrus communis 1. cv Passe Crassane) cells were subjected to temperatures of 39,42, and 45°C. Heat-shock protein (hsp) synthesis was greater at 39'C than at temperatures above 40'C and continued for up to 8 h. Both cellular uptake of radiolabeled methionine and total protein synthesis were progressively lower as the temperature was increased. Polysome levels decreased immediately...
Genetic maps for two pear cultivars ‘Red Bartlett’ (Pyrus communis L.) and ‘Nanguo pear’ (Pyrus ussuriensis Maxim.) were constructed using SRAP molecular markers. The mapping population consists of 74 F1 individuals derived from the cross of a cultivar ‘Red Bartlett’ with good fruit quality as the female parent and a cultivar ‘Nanguopear’ with good cold tolerance as the male parent. Linkage map...
We present a draft assembly of the genome of European pear (Pyrus communis) 'Bartlett'. Our assembly was developed employing second generation sequencing technology (Roche 454), from single-end, 2 kb, and 7 kb insert paired-end reads using Newbler (version 2.7). It contains 142,083 scaffolds greater than 499 bases (maximum scaffold length of 1.2 Mb) and covers a total of 577.3 Mb, representing ...
Rhizopus soft rot caused by Rhizopus stolonifer occurred on pears (Pyrus serotina) in the Jinju City Agricultural Products Wholesale Market in Korea from 2004 to 2005. The infection usually started from wounds due to cracking at harvest time. The lesions started as water-soaked, rapidly softened, then gradually expanded. The mycelia grew vigorously on the surface of the fruits and formed stolon...
The Ussurian pear is the most important cultivated pear in the northern part of China. Cultivated Ussurian pears are considered to have derived from Pyrus ussuriensis Maxim. which is native to the northeast of China. In Japan, two varieties of P. ussuriensis, P. ussuriensis var. aromatica and var. hondoensis are native to the northern area and the central area of the main island respectively. I...
در این مطالعه، ساختارتشریحی برگ و دمبرگ 10 گونه ایرانی از جنس گلابی متعلق به چهار بخش Pashia , Pyrus, Xeropyrenia, Argyromalonبه همراه یک گونه کاشته شده نزدیک گونه Pyrus syriaca ارائه می شود. این گونه هاعبارتنداز: Pyrus kandevanica Gahreman & Khatamsaz, P. boissieriana Buhse, P. mazanderanica Schonbeck- Temesy, P. hyrcana Fedor, P. turcomanica Maleev, P. elaeagnifolia Pall., P. salicifolia P...
Some local cultivars and wilds of Iwateyamanashi (Pyrus ussuriensis var. aromatica) that grows wild in Northern Tohoku, Japan have good aromatic fruit. Iwateyamanashi may be valuable germplasms as a donor of odor compounds in breeding of Japanese pear (Pyrus pyrifolia), because almost all Japanese pear cultivars have faint odor. Fruits odors from a local cultivar 'Sanenashi', a wild accession (...
Micromorphological study on the seeds of wild species Pyrus (Rosaceae) in Iran and their taxonomic implication
BACKGROUND Pyrus pashia Buch.-Ham. ex D. Don. has been used conventionally by many communities in the Himalayan region for the management of gastrointestinal, respiratory, and vascular complications. Set against this background, this study was carried out to justify the scientific basis to validate folkloric uses of fruits of Pyrus pashia Buch.-Ham. ex D. Don. (Pp.Cr) in traditional systems of ...
گونه pyrus pashia به عنوان گزارشی جدید از شمال شرق ایران گزارش می شود. این گونه با دارا بودن برگ های 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 می گردد.
