Grasshopper genome reveals long-term conservation of the X chromosome and temporal variation in X chromosome evolution
<p>We present the first chromosome-level genome assembly of the grasshopper, <em>Locusta migratoria</em>, one of the largest insect genomes. We use coverage differences between females (XX) and males (X0) to identify the X chromosome gene content, and find that the X chromosome shows both complete dosage compensation in somatic tissues and an underrepresentation of testes-expressed genes. Remarkably, X-linked gene content from <em>L. migratoria </em>is highly conserved across four insect orders, namely Orthoptera, Hemiptera, Coleoptera and Diptera, and the 800 Mb grasshopper X chromosome is homologous to the fly ancestral X chromosome despite 400 million years of divergence, suggesting either repeated origin of sex chromosomes with highly similar gene content, or long-term conservation of the X chromosome. We use this broad conservation of the X chromosome to test for temporal dynamics to Fast-X evolution, and find evidence of a recent burst evolution for new X-linked genes in contrast to slow evolution of X-conserved genes. Additionally, our results reveal the X chromosome represents a hotspot for adaptive protein evolution related migration and the locust swarming phenotype. Overall, our results reveal a remarkable case of conservation and adaptation on the X chromosome.</p>

A chromosome-scale de novo genome assembly of the dwarf tomato variety Micro-Tom
<p>The cultivated tomato (<em>Solanum lycopersicum</em>) is an important crop and model species for genetics and plant molecular biology research. The dwarf tomato variety Micro-Tom is used extensively in research because it is rapid flowering, easy to grow in high volumes in minimal space, and is amenable to genetic transformation. Here we provide a de novo chromosome-scale genome assembly of Micro-Tom that was generated using PacBio HiFi reads and scaffolded using chromosome confirmation capture data. The HiFi data was assembled using the Hifiasm assembler and OmniC data was used for scaffolding using Salsa and several rounds of manual curation and validation.</p>
