The importance of whole-genome duplication (WGD) for evolution is controversial. Whereas some view WGD mainly as detrimental and an evolutionary dead end, there growing evidence that polyploidization can help overcome environmental change, stressful conditions, or periods extinction. However, despite much research, the mechanistic underpinnings why how polyploids might be able to outcompete outlive nonpolyploids at times upheaval remain elusive, especially autopolyploids, in which heterosis...
Polyploidy, resulting from whole‐genome duplication (WGD), is ubiquitous in nature and reportedly associated with extreme environments biological invasions. However, WGD usually comes great costs, raising questions about the establishment chance of newly formed polyploids. The surprisingly high number polyploid mixed‐ploidy species observed may be a consequence their continuous emergence or reflect stable persistence even coexistence ancestral ploidy under certain circumstances. empirical...
Abstract Aim Historical processes that shaped current diversity patterns of seaweeds remain poorly understood. Using Dictyotales, a globally distributed order brown as model, we test if historical biogeographical and diversification are comparable across clades. Dictyotales contain some 22 genera, three which, Dictyota , Lobophora Padina exceptionally diverse. Specifically, whether the evolutionary latitudinal in these clades line with tropical conservatism, out‐of‐the‐tropics or rate...
The immediate effects of plant polyploidization are well characterized and it is generally accepted that these morphological, physiological, developmental, phenological changes contribute to polyploid establishment. Studies on the environmental dependence whole-genome duplication (WGD) are, however, scarce but suggest altered by stressful conditions. As establishment seems be associated with disturbance, relationship between ploidy-induced phenotypical conditions highly relevant. Here, we...
Hybridization blurs species boundaries and leads to intertwined lineages resulting in reticulate evolution. Polyploidy, the outcome of whole genome duplication (WGD), has more recently been implicated promoting facilitating hybridization between polyploid species, potentially leading adaptive introgression. However, because are usually ephemeral states evolutionary history life it is unclear whether WGD-potentiated any appreciable effect on their diploid counterparts. Here, we develop a...
Whole-genome duplications, widely observed in plant lineages, have significant evolutionary and ecological impacts. Yet, our current understanding of the direct implications ploidy shifts on short- long-term evolution remains fragmentary, necessitating further investigations across multiple levels. Chlamydomonas reinhardtii is a valuable model organism with profound potential to study impact increase longer term laboratory environment. This partly due ability level. We developed strategy...
Effective monitoring of non-indigenous seaweeds and combatting their effects relies on a solid confirmation the status respective species. We critically analysed presumed seaweed species reported from Mediterranean Sea, Northeast Atlantic Ocean Macaronesia, resulting in list 140 whose nature is undisputed. For an additional 87 it unclear if they are native or (cryptogenic species) identity requires (data deficient species). discuss factors underlying both taxonomic biogeographic...
Abstract The spatial configuration and size of patches influence metapopulation dynamics by altering colonisation–extinction local density dependency. This forcing as determined the typology then imposes strong selection pressures on life‐history traits, which will in turn feed back ecological dynamics. Given relevance persistence for biological conservation, potential rescuing role evolution, a firm understanding these eco‐evolutionary processes is essential. We here follow systems’...
Abstract Premise In plants, whole‐genome duplication (WGD) is a common mutation with profound evolutionary potential. Given the costs associated superfluous genome copy, polyploid establishment enigmatic. However, in right environment, immediate phenotypic changes following WGD can facilitate establishment. Metabolite abundances are direct output of cell's regulatory network and determine much impact environmental genetic change on phenotype. While it well known that an increase bulk amount...
Summary Genome merging is a common phenomenon causing wide range of consequences on phenotype, adaptation, and gene expression, yet its broader implications are not well‐understood. Two genome expression remain particularly poorly understood: dosage effects evolution expression. We employed Chlamydomonas reinhardtii as model to investigate the asymmetric by crossing diploid with haploid strain create novel triploid line. Five independent clonal lineages derived from this line were evolved...

ABSTRACTABSTRACTIn this study we explore the introduction of brown alga Dictyota acutiloba in Mediterranean Sea and provide a substantive update on geographic distribution species, which was long thought to be confined Pacific Ocean. A critical assessment published records additional identifications based cox1, psbA rbcL genetic markers confirm presence D. at number locations Indo-Pacific as well three along Israeli coastline south-eastern Sea. The close affinity between introduced specimens...
Abstract Many organisms have more than two sets of chromosomes, due to whole genome duplication (WGD), and are thus polyploid. Despite usually being an ephemeral state in the history life, polyploidy is widely recognized as important source genetic novelty over macroevolutionary scales. More recently, has also been shown facilitate interspecific gene flow, circumventing reproductive barriers between their diploid ancestors. Yet, implications WGD-linked introgression on community-level...
