Can Repeated Reductive Genome Evolution Across Archaeplastida Explain Volatility in Traits?

open access: yesAdvanced Genetics, Volume 7, Issue 4, December 2026.
Genome evolution in Archaeplastida is often framed around gene gains and increasing complexity. Yet ancestral reconstructions reveal recurrent genome contraction, with ancestors frequently harboring larger gene repertoires than descendants. Across red algae, land‐plant ancestry, and embryophyte diversification, repeated expansion and reduction cycles ...

Significance of polyploidy and hybridization in evolution of European taxa of genus Arum

open access: yes, 2021
Polyploidy and hybridization are significant evolutionary trends that occur in a wide variety of plant species. This bachelor thesis includes current knowledge and data on arums with a focus on polyploidization and hybridization of the genus Arum.

A Critique of the Taxonomy of Subtribe Celmisiinae (Asteraceae: Tribe Astereae) With New Combinations in Pleurophyllum Hook.f. sens. lat. and Shawia hesperia (Heenan & Molloy) Heenan comb. nov.

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 4, December 2026.
This review is of the recently revised circumscriptions of the Pleurophyllum Hook.f. group and Shawia J.R.Forst. & G.Forst. of subtribe Celmisiinae, both centred in New Zealand. Recognition of Shawia is supported, and phylogenetic data recover seven well‐supported subclades treated as infrageneric sections.

POLYPLOIDY: EVOLUTIONARY ADAPTABILITY, AGRICULTURAL PROSPECTS, AND PRESSING CHALLENGES

open access: yes
Polyploidy is a genetic phenomenon characterized by the presence of more than two sets of chromosomes in an organism's cells, beyond the diploid state, playing a significant role in evolutionary processes.

Balancing gain and diversity: Optimal contribution selection for sustainable genetic improvement in sugarcane

open access: yesThe Plant Genome, Volume 19, Issue 4, December 2026.
Abstract Sugarcane (Saccharum spp. hybrids), the source of ∼80% of the worlds sugar, has experienced a plateau in genetic improvement over recent decades. This stagnation is largely due to the crop's complex polyploid genome and long breeding cycles, which limit the efficiency of traditional selection methods.

Genome evolution of Mediterranean olives following DNA repeats diversification

open access: yesThe Plant Genome, Volume 19, Issue 4, December 2026.
Abstract The olive tree (Olea europaea L. subsp. europaea) is one of the most representative perennial crops of the Mediterranean Basin, yet the genomic processes underlying its domestication and diversification remain poorly understood. Here, we investigated repeatome variation across 20 accessions, including 11 wild oleasters and nine cultivated ...

A Multi‐Tissue Transcriptomic Resource for the Brahminy Blindsnake Indotyphlops braminus (Squamata: Typhlopidae)

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
We analyzed multi‐tissue expression patterns in the all‐female, parthenogenetic, and triploid Brahminy blindsnake (Indotyphlops braminus) using PacBio and Illumina RNA‐seq to better understand polyploidy and asexual reproduction in vertebrates. By characterizing differential expression and co‐expression networks across the ovary, heart, liver, skin ...

Seascape genomics reveals high genetic diversity and apparent panmixia in endemic Southern Ocean phytoplankton

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract The adaptive potential and resilience of cold‐adapted phytoplankton to climate change have the potential to impact polar marine food webs and global biogeochemical cycles. Two central but poorly constrained facets of adaptive potential in polar phytoplankton are standing genetic diversity and its spatial structure. Here, we partially sequenced

Evolution and subfunctionalization of CIPK6 homologous genes in regulating cotton drought resistance

open access: yesNature Communications
The occurrence of whole-genome duplication or polyploidy may promote plant adaptability to harsh environments. Here, we clarify the evolutionary relationship of eight GhCIPK6 homologous genes in upland cotton (Gossypium hirsutum).
