- 1 March 2010
Ten EST-SSRs previously isolated from Pyrus were used to identify 81 P. ussuriensis or P. pyrifolia and 20 P. × bretschneideri accessions, and unsuspected relationships were uncovered, including a parental relationship between ‘Anjou’ and ‘Farmingdale’.

- 6 August 2007
Sequence and phylogenetic analysis indicate that the virus identified in the atypical ‘Variegata’ clone, designated as mint virus-2, is related to members of the species Grapevine virus A, grapevine virus B and Heracleum latent virus, placing it in the genus Vitivirus.

Nuclear and chloroplast microsatellite markers to assess genetic diversity and evolution in hazelnut species, hybrids and cultivars

The phylogeographical relationships among the 21 chlorotypes in the 11 Corylus species support Asia as a refugium where several hazelnut lineages survived during glaciation and from which they continued to evolve after dispersal from Asia through the Mediterranean to Europe, and across the Atlantic and/or the Bering land bridge to North America.
Diversity of wild Pyrus communis based on microsatellite analyses

It is concluded that genetic diversity of wild P. communis is not fully represented in the National Plant Germplasm System (NPGS) and more pear diversity could be captured through supplementary collection trips to eastern Europe, the Caucasus Mountains, and the surrounding countries.
Molecular characterization of a novel rhabdovirus infecting blackcurrant identified by high-throughput sequencing

A large contig with sequence similarities to several nucleorhabdoviruses was identified by high-throughput sequencing analysis from a black currant (Ribes nigrum L.) cultivar and may represent a new species in the genus NucleorhabDovirus.
Nomenclature and genetic relationships of apples and pears from Terceira Island

The objective of this study was to determine synonymy, homology, and phylogeny of apples and pears from Terceira and to examine potential relationships of the island pears with standard apples andpears of Portuguese or American descent.
Peroxidase Isozyme Profiles in Compatible and Incompatible Pear-Quince Graft Combinations

- 1 March 2002
It is suggested that matching of isoperoxidase 'A' in quince rootstocks and BH pear scion may be associated with a compatible graft combination, and presence of is operoxidases 'A and 'B' in the graft union tissues may be used as an indicator to predict acompatible graft between BT and quinceRootstocks.
Diversification and independent domestication of Asian and European pears

- BiologyGenome Biology
- 11 June 2018
This study proposes a model for the divergence, dissemination, and independent domestication of Asian and European pears in which pear has eventually spread to western Asia, and then on to Europe, thus promoting outcrossing and accounting for pear genome diversity across the Eurasian continent.
