Sustainable fruit production relies on the introduction of genetic resistance to diseases and pests from wild populations into the cultivated germplasm.
For identifying genes linked to agronomically important traits, we collected wild apricot populations of Apricot related species, they present a high level of genotypic and phenotypic diversity.
De novo genome assemblies were performed for the most important Armeniaca Fruit species (P.armeniaca, P. sibirica, P. mandshurica), in order to facilitate the introgression of valuable genes into the cultivated germplasm.
In the current project, we propose to compare their genome architecture and identify possible structural re-arrangements during Armeniaca evolutionary history.

Abstract
Cucumis melo displays a large diversity of horticultural groups with Cantaloupe melon the most cultivated type. Using a combination of single-molecule sequencing, 10X Genomics link-reads, high-density optical and genetic maps and chromosome conformation capture (Hi-C) we assembled a chromosome scale C.melo var. cantalupensis Charentais mono genome. Integration of RNA-seq, MeDip-seq, ChIP-seq and Hi-C data revealed a widespread compartmentalization of the melon genome, segregating constitutive heterochromatin and euchromatin. Genome-wide comparative and evolutionary analysis between melon botanical groups identified Charentais mono genome increasingly more divergent from Harukei-3 (reticulatus), Payzawat (inodorus), and HS (ssp. agrestis) genomes. To assess the paleohistory of the Cucurbitaceae, we reconstructed the ancestral Cucurbitaceae karyotype and compared it to sequenced cucurbit genomes. In contrast to other species that experienced massive chromosome shuffling, melon has retained the ancestral genome structure. We provide comprehensive genomic resources and new insights in the diversity of melon horticultural groups and evolution of cucurbits.
