Identification of European and Asian pears using EST-SSRs from Pyrus
TLDR
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’.
Identification, detection and transmission of a new vitivirus from Mentha
TLDR
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.
Phylogeny and evolutionary histories of Pyrus L. revealed by phylogenetic trees and networks based on data from multiple DNA sequences.
TLDR
This study collected 110 accessions representing 25 Pyrus species and constructed both phylogenetic trees and phylogenetic networks based on multiple DNA sequence datasets, suggesting that reticulation caused by hybridization is one of the major evolutionary processes for P Cyrus species.
Diversity of wild Pyrus communis based on microsatellite analyses
TLDR
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.
A virus between families: nucleotide sequence and evolution of Strawberry latent ringspot virus.
TLDR
Strawberry latent ringspot virus (SLRSV) shares characteristics with members of the Cheravirus, Fabav virus, Comovirus and Sadwavirus genera indicative of the uniqueness of SLRSV.
Emerging Fruit Crops
TLDR
This chapter examines nine emerging crops chosen among hundreds of potential crops which are currently showing much promise as commercial crops, and four berry crops, namely, blue honeysuckle, elder, goji, and ‘ōhelo.
Diversification and independent domestication of Asian and European pears
TLDR
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.
The Distinctive Morphology of `Fragaria multicipita' Is Due to Phytoplasma
TLDR
Results indicated that F. multicipita is a phytoplasma-diseased aberrant growth form of F. virginiana Duchesne and is an unfounded taxon, and it is apparent that this plant population offers no unique potential for increasing genetic diversity in cultivated strawberry germplasm.
Nuclear and chloroplast microsatellite markers to assess genetic diversity and evolution in hazelnut species, hybrids and cultivars
TLDR
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.
Nomenclature and genetic relationships of apples and pears from Terceira Island
TLDR
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.
