Ecological niches in the polyploid complex Linum suffruticosum s.l. [PDF]
Frontiers in Plant Science, 2023 IntroductionThe high frequency of polyploidy in the evolutionary history of many plant groups occurring in the Mediterranean region is likely a consequence of its dynamic paleogeographic and climatic history.

Circadian regulation of the transcriptome in a complex polyploid crop [PDF]
PLoS Biology, 2022 The circadian clock is a finely balanced timekeeping mechanism that coordinates programmes of gene expression. It is currently unknown how the clock regulates expression of homoeologous genes in polyploids. Here, we generate a high-resolution time-course

The speciation and adaptation of the polyploids: a case study of the Chinese Isoetes L. diploid-polyploid complex. [PDF]
BMC Evol Biol, 2020 AbstractBackgroundThe ChineseIsoetesL. are distributed in a stairway pattern: diploids in the high altitude and polyploids in the low altitude. The allopolyploidI. sinensisand its diploid parentsI. yunguiensisandI. taiwanensisis an ideal system with which to investigate the relationships between polyploid speciation and the ecological niches ...

Evaluation of Reference Genes in the Polyploid Complex Dianthus broteri (Caryophyllaceae) Using qPCR [PDF]
Plants, 2022 Dianthus broteri is an endemic complex which is considered the largest polyploid series within the Dianthus genus. This polyploid species involves four cytotypes (2×, 4×, 6× and 12×) with spatial and ecological segregation.

So Closely Related and Yet So Different: Strong Contrasts Between the Evolutionary Histories of Species of the Cardamine pratensis Polyploid Complex in Central Europe [PDF]
Frontiers in Plant Science, 2020 Recurrent polyploid formation and weak reproductive barriers between independent polyploid lineages generate intricate species complexes with high diversity and reticulate evolutionary history.

Variation in heteroploid reproduction and gene flow across a polyploid complex: One size does not fit all [PDF]
Ecology and Evolution, 2021 Whole‐genome duplication is considered an important speciation mechanism in plants. However, its effect on reproductive isolation between higher cytotypes is not well understood.

Genetic variation in the brooding brittle-star: a global hybrid polyploid complex? [PDF]
Royal Society Open ScienceThe widespread and abundant brooding brittle-star (Amphipholis squamata) is a simultaneous hermaphrodite with a complex mitochondrial phylogeography of multiple divergent overlapping mtDNA lineages, high levels of inbreeding or clonality and unusual ...
