Partial preferential chromosome pairing is genotype dependent in tetraploid rose

SUMMARYIt has long been recognised that polyploid species do not always neatly fall into the categories of autoor allopolyploid, leading to the term 'segmental allopolyploid' to describe everything in between. The meiotic behaviour of such intermediate species is not fully understood, nor is there consensus as to how to model their inheritance patterns. In this study we used a tetraploid cut rose (Rosa hybrida) population, genotyped using the 68K WagRhSNP array, to construct an ultra-high-density linkage map of all homologous chromosomes using methods previously developed for autotetraploids. Using the predicted bivalent configurations in this population we quantified differences in pairing behaviour among and along homologous chromosomes, leading us to correct our estimates of recombination frequency to account for this behaviour. This resulted in the re-mapping of 25 695 SNP markers across all homologues of the seven rose chromosomes, tailored to the pairing behaviour of each chromosome in each parent. We confirmed the inferred differences in pairing behaviour among chromosomes by examining repulsionphase linkage estimates, which also carry information about preferential pairing and recombination. Currently, the closest sequenced relative to rose is Fragaria vesca. Aligning the integrated ultra-dense rose map with the strawberry genome sequence provided a detailed picture of the synteny, confirming overall co-linearity but also revealing new genomic rearrangements. Our results suggest that pairing affinities may vary along chromosome arms, which broadens our current understanding of segmental allopolyploidy.

“…The specificities of the domestication process in perennials are partly due to clonal propagation and long juvenile phases, that both reduce the number of sexual cycles separating domesticated individuals from their wild progenitors (Gaut et al, 2015;Miller & Gross, 2011). Recent studies have corroborated such expectations by documenting the domestication history of several perennial crops, in particular of tree species cultivated for fruit consumption (Besnard et al, 2013(Besnard et al, , 2017Cornille et al, 2012;Decroocq et al, 2016;Delplancke et al, 2013;Gros-Balthazard et al, 2017;Gross & Olsen, 2010;Hazzouri et al, 2015;Wincker, 2013) or ornamental purposes (Iwata, Kato, & Ohno, 2000;Liorzou et al, 2016;Yuan, Cornille, Giraud, Cheng, & Hu, 2014). These studies also revealed that domestication in fruit trees often involved gene flow from multiple wild species in different geographic areas, such as in citrus (Wu et al, 2018), apple (Cornille et al, 2012), olive (Besnard et al, 2017), peach (Yu et al, 2018), banana (Martin et al, 2017) and date palm (Flowers et al, 2019).…”

The complex evolutionary history of apricots: Species divergence, gene flow and multiple domestication events

et al. 2019

Domestication is an excellent model to study diversification and this evolutionary process can be different in perennial plants, such as fruit trees, compared to annual crops. Here, we inferred the history of wild apricot species divergence and of apricot domestication history across Eurasia, with a special focus on Central and Eastern Asia, based on microsatellite markers and approximate Bayesian computation. We significantly extended our previous sampling of apricots in Europe and Central Asia towards Eastern Asia, resulting in a total sample of 271 cultivated samples and 306 wild apricots across Eurasia, mainly Prunus armeniaca and Prunus sibirica, with some Prunus mume and Prunus mandshurica. We recovered wild Chinese species as genetically differentiated clusters, with P. sibirica being divided into two clusters, one possibly resulting from hybridization with P. armeniaca. Central Asia also appeared as a diversification centre of wild apricots. We further revealed at least three domestication events, without bottlenecks, that gave rise to European, Southern Central Asian and Chinese cultivated apricots, with ancient gene flow among them. The domestication event in China possibly resulted from ancient hybridization between wild populations from Central and Eastern Asia. We also detected extensive footprints of recent admixture in all groups of cultivated apricots. Our results thus show that apricot is an excellent model for studying speciation and domestication in long‐lived perennial fruit trees.
