Summary: Sterile yeast hybrids can generate genetic diversity through meiotic-like recombination by aborting meiosis and returning to asexual growth. Recombination promoted by this process can lead to regions of loss-of-heterozygosity and impact sexual and asexual fitness. Return-to-growth provides a natural route for genome recombination and adaptation in sterile yeast hybrids.

Summary: Hybridization and polyploidization are crucial for plant evolution, but classifying hybrid or polyploid species has been challenging due to their complex processes and non-conformity to classical species concepts. Lineage formation resulting from meiotic sex can help overcome traditional thinking of species as units and can be applied to hybrids and polyploids.

Summary: Present-day African cattle have a unique genetic profile resulting from a mixture of Bos taurus and Bos indicus populations. Research suggests that the earliest domestic cattle in Africa likely had a significant contribution from an extinct African aurochs lineage, and the indicine ancestry of African cattle is closely related to both North Indian and Southeast Asian indicine breeds.

Summary: This study investigates the temporal evolutionary dynamics of four Oryza polyploid genomes at both genetic and expression levels, revealing an ongoing diploidization process in the genus. The findings shed light on the genome evolution after allopolyploidy and suggest that expression divergence driven by changes of selective constraint plays a major role in long-term diploidization.

Summary: Genome dominance is observed in wide hybrids, where one parental genome becomes dominant over the other, leading to unequal retention of parental chromosomes in successive generations. Female meiotic drive is identified as the key factor underlying this dominance, with variations in strength across different chromosome segments.

Summary: The study indicates that hybridization or whole-genome duplication (WGD; allopolyploidy) can improve plants' tolerance to nitrogen deficiency and result in less perturbed gene expression from parental legacy. Genetic additivity may lead to similar beneficial phenotypic responses to nitrogen stress compared with the parents.

Summary: Certain genomic features in genome sequencing and assembly can lead to low-quality assemblies. This study presents Karyon, a Python-based toolkit that assesses parameters and generates informative plots to identify noncanonical genomic traits. Testing on 35 highly fragmented fungal assemblies, it was found that 10 assemblies displayed unusual genomic configurations.

Summary: In this study, the rare occurrence of hybridization among Acropora species was discovered, with the hybrids showing a preference for self-fertilization and the ability to backcross with parental species. The small population size of hybrids and their tendency to choose efficient sexual reproduction tactics were observed.

Summary: Two cultivated allopolyploid cottons, G. hirsutum and G. barbadense, underwent parallel independent domestication processes, involving significant morphological transformations. Wild forms of both species were initially domesticated in the Yucatan Peninsula and NW South America, respectively, before spreading over 4000-8000 years to encompass most of the American tropics. Genome-wide bidirectional introgression occurred between the two co-resident genomes of these allopolyploids, revealing genetic asymmetries and regions targeted during domestication.

Summary: This study investigates the application of genome-wide prediction in hybrids with exotic introgressions, finding that prediction ability is influenced by trait complexity, exotic introgression, genetic relationships, training set size, and environments. The results suggest that predicting traits with complex architecture in hybrids may be more challenging due to these factors.

Summary: This study presents the progress in understanding the genome of camelina, revealing the molecular evolutionary history of the polyploid complex. By studying the tetraploid camelina genome in detail, researchers have identified a high collinearity with two maternally inherited subgenomes of the hexaploid camelina.

Summary: Understanding local adaptations in mountain hares is crucial for evolutionary biology and conservation, and combining RAD sequencing with whole-genome sequencing revealed genetic signatures of local adaptation in different geographical areas. Candidate genes associated with environment-related traits were identified, showing the importance of adaptive variation in shaping the post-glacial dynamics of species.

Summary: Domestication of grapevines is a selection process driven by humans, with debates over the number and locations of domestication events. Multiple independent domestication events and gene flow have complicated genetic relationships.

Summary: Understanding the origins and impacts of novel traits, this study expands the research scope in the realms of ecology and evolutionary biology, encompassing novelties across biological scales and eco-evolutionary perspectives. By defining novelties as new features at one biological scale that have emergent effects at other biological scales, the authors incorporate many forms of novelty and outline a broad array of generative mechanisms underlying novelty. They also highlight how genomic tools are transforming our understanding of the origins of novelty and present case studies to illustrate common mechanisms of change and their environmental and genetic contexts.

Summary: This study sequenced and analyzed the genomes of multiple Camelina species to reveal the ancestral relationships contributing to C. sativa's sub-genomes, and identified the critical role of transposable elements in evolution. Overall, the diploid genomes showed few structural differences compared to C. sativa's genome, providing important insights for further research on plant evolution.
