               Symphonia globulifera (Clusiaceae) has emerged as a model organism in tropical forest ecology and evolution due to its significant ecological role and complex biogeographical history. Originating from Africa, this species has independently colonized Caribbean, Central and South America three times, becoming a key component of tropical ecosystems across these regions. Despite the ecological importance of S. globulifera and other tropical tree species, our understanding of their genomic architecture remains limited compared to temperate species. To bridge this gap, we present a comparative analysis of two de novo-assembled nuclear genomes of S. globulifera – one from a South American individual and one from an African individual – and report newly assembled chloroplast and mitochondrial genomes. Initial assembly of the organelles was performed using GetOrganelle, and the results were compared with corresponding publicly available sequences from closely related Garcinia species. Our study introduces novel genomic resources, including an annotated nuclear draft genome based on Illumina short reads, the first chloroplast genome assembly for the genus, and a set of assembled mitochondrial gene sequences. Additionally, we provide a set of single-copy nuclear gene alignments identified by BUSCO as well as manually curated coding plastid genes, which will serve as valuable tools for future comparative analyses and phylogenetic studies. Our preliminary results based on chloroplast genes and limited sampling suggest that Garcinia might be non-monophyletic. The detected differences in nuclear and organellar genomes reveal high intraspecific variation, emphasizing the importance of genome-wide sampling for understanding tropical tree evolution.},

abstract = {AbstractThe field elm (Ulmus minor) is an emblematic species of the European landscape, which has been severely affected by Dutch elm disease (DED) since the 20th century. To support restoration and conservation of this species and congeners, we present a de novo assembly and annotation of a wild genotype tested positive for DED resistance, along with a comprehensive phylogenetic analysis with related species. Cutting‐edge sequencing technologies were used alongside high‐throughput chromosome conformation capture technologies for chromosome conformation capture. Our assembly spans approximately 2.1 Gb, with scaffold and contig N50 sizes of 133.765 and 8.189 Mb, respectively. Repetitive elements account for 81.45% of the genome size. Using transcriptomic information from 19 tissues in varying developmental stages and gene model prediction techniques, a total of 46,357 protein‐coding genes were annotated, 99.70% of which were functionally characterized. An analysis of the presence and arrangement of resistance genes on U. minor, and sister species Ulmus glabra and Ulmus parvifolia, revealed a clustered and syntenic distribution across all of them, with a higher density in U. minor. This genomic resource and its analytical dissection herein introduced represent valuable tools for future in‐depth studies on the resistance mechanisms to DED. Additionally, this study completes the phylogenetic context within the order Rosales and provides a robust framework for future research.},
