Abstract Background and Aims The duckweeds (Lemnaceae) consist of 36 species exhibiting impressive phenotypic variation, including the progressive evolutionary loss a fundamental plant organ, root. Loss roots reduction vascular tissues in recently derived taxa occur concert with genome expansions ≤14-fold. Given paired structural complexity taxa, we focus on evolution ionome (whole-plant elemental contents) context these changes body plan. We expect that vestigiality eventual might have both adaptive maladaptive consequences are hitherto unknown.

Fine‐Scale Variation in Soil Properties Promotes Local Taxonomic Diversity of Hybridizing Oak Species (Quercus spp.)

Evolutionary Applications, Год журнала: 2025, Номер 18(2)

Although many tree species frequently hybridize and backcross, management decisions in forestry nature conservation are usually concentrated on pure species. Therefore, understanding which environmental factors drive the distribution admixture of a local stand scale is great interest to support decision-making establishment resilient forests. Here, we extensively sampled mixed hybridizing white oaks (Quercus petraea Q. pubescens) near Lake Neuchâtel (Switzerland), where limestone glacier moraine geologies coexist proximity, test whether micro-environmental conditions can predict taxonomic genetic admixture. We collected DNA from bud tissue, individual soil samples, extracted high-resolution topographic data for 385 oak trees. used 50 species-discriminatory single nucleotide polymorphism (SNP) markers determine composition levels trees tested their association with conditions. show that trees' be explained mainly by geographic position, pH, potential rooting depth, proxy water availability. found admixed individuals tend grow habitats characteristic more drought-tolerant pubescens rather than intermediate habitats. Using situ measurements, first fine-scale variation properties related pH availability potentially drives stand. Microenvironmental therefore promotes diversity, facilitates adaptive introgression, contributes resilience forests under change. Consequently, such as should managed protected complex

Genome diversity and evolution of the duckweed section Alatae comprising diploids, polyploids, and interspecific hybrids

The Plant Journal, Год журнала: 2025, Номер 122(2)

Опубликована: Апрель 1, 2025

SUMMARY The section Alatae of genus Lemna the monocotyledonous aquatic duckweed family (Lemnaceae) consists rather diverse accessions with unknown phylogeny and unclear taxonomic assignment. In contrast to other duckweeds, some accessions, in addition mainly vegetative propagation, produce readily flowers viable seeds. We analyzed genomic diversity phylogenetic relationship 52 accessions. For this purpose, we applied multiple molecular cytogenetic approaches, including plastid nuclear sequence polymorphisms, chromosome counting, genome size determination, situ hybridization combination geographic distribution. uncovered ploidy variation, recurrent hybridization, backcrosses between species their hybrids. latter successfully spread over three continents. results elucidate evolution explain difficult assignment distinct Our study might be an example for analogous studies resolve hitherto relationships among genera Wolffiella Wolffia .

Abstract Interspecific hybridization and polyploidization are recognized as two main driving forces in plant evolution, shaping genomes favoring evolutionary novelty ecological adaptation. Recent studies have demonstrated within the genus Lemna (Lemnaceae Martinov). minor has given rise to interspecific hybrids: × japonica , a species since 1980, newly discovered L . mediterranea identified among germplasm collection clones. hybrid between gibba was hypothesized correspond symmeter which invalidly described about 50 years ago Southern Italy. A sampling campaign eight populations of hybrid, at different sites across Campania region, The isolated specimens were found be genetically identical by nuclear marker Tubulin-based polymorphism (TBP), likely belonging same original clone (LER-LME) distinct from previously analyzed clones, suggesting recurrent hybridization. natural is triploid, with plastid donor. Morphology very similar although typical gibbosity this becomes evident only upon flower induction. Flowers protogynous self-sterile. Populations both parent species, recovered during survey, recording high genetic variability minor. Other Lemnaceae Wolffia arrhiza trisulca also occasionally present. presence invasive minuta seems less prevalent respect other Italian regions. Synthesis: Five cryptic for first time wild Clones these populations, sampled water bodies over an area 4200 Km 2 indistinguishable originated event. Thanks intron polymorphism, TBP provides straightforward method identifying sterile clonal lineages tracking their spatial temporal distribution. Ecological factors including competition parental niche climate change adaptation, stability space investigated.

The role of recombination landscape in species hybridisation and speciation

Frontiers in Plant Science, Год журнала: 2023, Номер 14

It is now well recognised that closely related species can hybridize and exchange genetic material, which may promote or oppose adaptation speciation. In some cases, interspecific hybridisation very common, making it surprising identity preserved despite active gene exchange. The genomes of most eukaryotic are highly heterogeneous with regard to density, abundance repetitive DNA, chromatin compactisation etc, make certain genomic regions more prone resistant introgression material from other species. Heterogeneity in local recombination rate underpins many the observed patterns across genome (e.g. actively recombining typically rich depleted for DNA) strongly affect permeability introgression. larger region lacking recombination, higher chance presence incompatibility gene(s) region, entire non- rarely block impermeable Large plant tend have landscape, frequently occurring at ends chromosomes central recombination. this paper we review relationship between plants argue large likely play a major role preserving hybridising

Maintenance of a narrow hybrid zone between native and introduced red foxes (Vulpes vulpes) despite conspecificity and high dispersal capabilities

Abstract Human‐facilitated introductions of nonnative populations can lead to secondary contact between allopatric lineages, resulting in lineage homogenisation or the formation stable hybrid zones maintained by reproductive barriers. We investigated patterns gene flow native Sacramento Valley red fox ( Vulpes vulpes patwin ) and introduced conspecifics captive‐bred origin California's Central Valley. Considering their recent divergence (20–70 kya), we hypothesised that any observed barriers were primarily driven pre‐zygotic (e.g. behavioural differences) rather than post‐zygotic reduced fitness) also explored whether genes could confer higher fitness human‐dominated landscape selective introgression into population. Genetic analysis foxes n = 682) at both mitochondrial (cytochrome b + D‐loop) nuclear (19,051 SNPs) loci revealed narrower cline widths expected under a simulated model unrestricted flow, consistent with existence identified several previously linked domestic canids, supporting pre‐zygotic, yet possibly hereditary, as mechanism driving narrowness stability zone.
