A New Species of Arthropteris From Samoa

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
A new species, Arthropteris samoensis (Arthropteridaceae), recorded from the Samoan islands of Upolu and Savai‘i, is described and illustrated. In Samoa, the new species is distinguished from Arthropteris palisotii s.l. by its smaller stature and more delicate texture (laminae mostly < 3 cm wide vs.

Binucleation ramps up gene expression meeting the physiological demands of an organism

PLoS Biology, 2022
In this issue of PLOS Biology, van Rijnberk and colleagues show how polyploidy, via binucleation, enables Caenorhabditis elegans intestinal cells to ramp up gene expression supplying the oocytes with the necessary lipids for optimal organismal growth and

Ploidy‐Level, Spore Size, and Morphological Variation of Plagiogyria adnata (Plagiogyriaceae) Along an Elevational Cline on Yakushima Island, Japan

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
Yakushima Island is a major biodiversity hotspot where complex environmental gradients and high endemism provide an ideal setting for studying plant evolution. In this study, we investigated the relationships among ploidy variation, morphology, and environmental factors in populations of Plagiogyria adnata, including the variety P.

Genotype-specific responses to polyploidy induction in coriander using colchicine treatments

Discover Plants
Polyploidy plays a critical role in driving diversification and adaptation in many plant species, affecting physiological, developmental, and morphological traits. Here, we explore genotype-specific responses to colchicine-induced polyploidy in coriander

Genome Editing in Root and Tuber Crop Development in Sub‐Saharan Africa

Plant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT Precision genome editing, particularly using Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR‐associated protein 9 (Cas9), is advancing crop improvement by enabling targeted and efficient genetic modifications. Root and tuber crops such as potato, cassava, sweet potato, and yam are vital for global food and nutritional

Does polyploidy facilitate long-distance dispersal?

, 2014
Background and AimsThe ability of plant lineages to reach all continents contributes substantially to their evolutionary success. This is exemplified by the Poaceae, one of the most successful angiosperm families, in which most higher taxa (tribes ...

Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

TAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...

Polyploidy with specific view to paleopolyploidy and its detection [PDF]

, 2017
Polyploidy is a significant phenomenon in the evolution of eucaryotic organisms. It has been a subject of interest of biologists for decades and it has been studied particularly largely in plants, where it most often occurs.

Marigold Cell Size and Polyploidy

, 2004
Most animals are diploid, having one set of chromosomes from the male and one from the female. Polyploid animals, with the exception of some frogs and fish, are usually aborted or die immediately after birth (Gardner et al., 1991).

Wheat's war against stripe rust: Integrating host immunity, genomics and breeding for durable resistance

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.
