Genomewide analyses of the transcriptome have confirmed that gene misexpression may underlie reproductive isolation mechanisms in interspecific hybrids. Here, using a 16,006 features cDNA microarray, we compared and contrasted gene expression divergence at two ontogenetic stages in incipient species of normal and dwarf whitefish (Coregonus clupeaformis) with that of first generation (normal x d...
Pepper species exhibit broad genetic diversity, which enables their use in breeding programs. The objective of this study was to characterize the diversity between the parents of different species and their interspecific hybrids using morphological and molecular markers. The parents of Capsicum annuum (UFPB-01 and -137), C. baccatum (UFPB-72), and C. chinense (UFPB-128) and their interspecific ...
Several lines of evidence suggest that, within a lineage, particular genomic regions are subject to instability that can lead to specific types of chromosome rearrangements important in species incompatibility. Within family Macropodidae (kangaroos, wallabies, bettongs, and potoroos), which exhibit recent and extensive karyotypic evolution, rearrangements involve chiefly the centromere. We prop...
Hybridization is often considered maladaptive, but sometimes hybrids can invade new ecological niches and adapt to novel or stressful environments better than their parents. The genomic changes that occur following hybridization that facilitate genome resolution and/or adaptation are not well understood. Here, we examine hybrid genome evolution using experimental evolution of de novo interspeci...
This study was carried out to evaluate factors affecting establishment and proliferation of two apricot × plum (Prunus armenica × Prunus domestica) interspecific hybrids HS405 and HS706. These hybrid rootstocks are resistant to diseases and pathogens and have been developed in East Azarbayjan Agricultural and Natural Resources Research Center, Tabriz, Iran. Propagation of these hybrids through...
