The Plant Journal, Volume 122, Issue 2, April 2025.SUMMARY The section Alatae of genus Lemna of the monocotyledonous aquatic duckweed family (Lemnaceae) consists of rather diverse accessions with unknown phylogeny and unclear taxonomic assignment. In contrast to other duckweeds, some Alatae accessions, in addition to mainly vegetative propagation, produce readily flowers and viable seeds.

, 2013 The kinetochore plays important roles in cell cycle progression. Interactions between 4 chromosomes and spindle microtubules allow chromosomes to congress to the middle of the 5 cell and to segregate the sister chromatids into daughter cells in mitosis ...

Frontiers in Genetics, 2020 Heterozygotes for major chromosomal rearrangements such as fusions and fissions are expected to display a high level of sterility due to problems during meiosis. However, some species, especially plants and animals with holocentric chromosomes, are known

Dysdera parthenogenetica sp. nov. (Araneae, Dysderidae): A Unique Case of Parthenogenesis in Spiders
Journal of Zoological Systematics and Evolutionary Research, Volume 2025, Issue 1, 2025.We studied the parthenogenetic lineages of the spider Dysdera hungarica (Araneae: Dysderidae). Based on our data, we consider them to constitute a separate taxon, Dysdera parthenogenetica sp. nov. Morphologically, the new species differs mainly by slightly reduced female copulatory organs.

, 2010 Chromosome rearrangements may affect the rate and patterns of gene flow within species, through reduced fitness of structural heterozygotes or by reducing recombination rates in rearranged areas of the genome.

Unique territorial and compartmental organization of chromosomes in the holocentric silkmoth
Abstract The hallmarks of chromosome organization in multicellular eukaryotes are chromosome territories (CT), chromatin compartments, and insulated domains, including topologically associated domains (TADs). Yet, most of these elements of chromosome organization are derived from analyses of a limited set of model organisms, while large ...
