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 (...
Contribution des explorateurs français à l'étude de la flore l'Asie Centrale: les collections d'herbier Guillaume Capus (1857-1931). Les explorations en Asie Centrale entre 1880 et 1887 ont notamment abouti une collection remarquable 3000 spécimens d'herbiers, toujours conservés dans l'Herbier Paris (France). récoltes sa première exploration été rapidement déterminées par un autre botaniste fra...
