d'Anjou cv. pear fruit (Pyrus communis L.) exposed at harvest to 0, 0.42, 4.2, or 42 micromol m(-)(3) 1-methylcyclopropene (1-MCP) for 12 h at 20 degrees C were stored at 1 degrees C for up to 8 months. After storage, half of the fruit was continuously exposed to ethylene (0.45 or 4-18 mmol m(-)(3)) for 7 days at 20 degrees C. All fruit treated with 1-MCP had lower respiration and ethylene prod...
This study was aimed at evaluating the antioxidant and antidiabetic activities of methanolic extracts peel, flesh mixed flesh, as well cytotoxic activity peel obtained from fruits six traditional pear varieties (Vidovaca, Lubenicarka, Karamanka, Jeribasma, Loncara Takisa), one commercial variety (Williams Bartlett) a wild (Pyrus communis) Serbia. The tested showed strong regarding prevention ?-...
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...
Using cultured pear (Pyrus communis cv Bartlett) cells, heat tolerance induced by heat shock was compared to that developed during growth at high temperature. After growth at 22 degrees C, cells exposed to 38 degrees C for 20 minutes (heat shock) showed maximum increased tolerance within 6 hours. Cells grown at 30 degrees C developed maximum heat tolerance after 5 to 6 days; this maximum was we...
Two new species belonging to the family Stigmaeidae, Cheylostigmaeus tarae sp. nov. and Stigmaeus delaramae sp. nov., are described from specimens collected from soil and litter under pear trees, Pyrus communis L. (Rosaceae) in Iran. A key to all Iranian species of the genera Cheylostigmaeus (male) and Stigmaeus (female) are provided.
We developed retrotransposon-based insertional polymorphism (RBIP) markers based on the long terminal repeat (LTR) sequences of copia-like retrotransposon Ppcrt4 and flanking genome sequences, which were derived from 454 sequencing data from Japanese pear (Pyrus pyrifolia) 'Hosui'. Out of 40 sequences including both LTR and flanking genome regions, we developed 22 RBIP markers and used them for...
We have used new generation sequencing (NGS) technologies to identify single nucleotide polymorphism (SNP) markers from three European pear (Pyrus communis L.) cultivars and subsequently developed a subset of 1096 pear SNPs into high throughput markers by combining them with the set of 7692 apple SNPs on the IRSC apple Infinium® II 8K array. We then evaluated this apple and pear Infinium® II 9K...
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 ...
Genetic maps are essential tools for pear genetics and genomics research. In this study, we first constructed an integrated simple sequence repeat (SSR) and single nucleotide polymorphism (SNP)-based consensus genetic map for pear based on common SSR markers between nine published maps. A total of 5,085 markers, including 1,232 SSRs and 3,853 SNPs, were localized on a consensus map spanning 3,2...
The response of suspension-cultured pear (Pyrus communis cv Bartlett) cells to heat stress was studied using three viability tests: regrowth (culture growth during 10 days after stress); triphenyltetrazolium chloride reduction; and electrolyte leakage. Critical (50% injury) temperatures for a 20-minute exposure were 42 degrees , 52 degrees , and 56 degrees C, respectively, for these viability t...
