Longevity in plants impacts phylogenetic and population dynamics

New Phytologist, Volume 250, Issue 1, Page 661-671, April 2026.
Summary Phylogenies of long‐lived plants often exhibit short molecular branch lengths and high levels of gene‐tree conflict. However, the biological mechanisms underlying these patterns remain unclear. We examine this with simulations and through empirical examination of several large seed plant clades.

Polyploidy and the Cellular and Areal Diversity of Rat Cortical Layer 5 Pyramidal Neurons

Cell Reports, 2017
In many species, polyploidy, in which an increase in nuclear DNA content is accompanied by an increase in cell size, contributes to cellular diversity.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

New Phytologist, Volume 250, Issue 1, Page 629-647, April 2026.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Strain, procedures, and tools for reproducible genetic transformation and genome editing of the emerging plant model Spirodela polyrhiza

New Phytologist, Volume 250, Issue 2, Page 735-756, April 2026.
Summary Duckweeds (Lemnaceae) have excellent potential for fundamental and applied research due to ease of cultivation, small size, and continuous fast clonal growth. However, their usage as model organisms and platforms for biotechnological applications is often limited by the lack of universal genetic manipulation methods necessary for transgene ...

Small RNAs regulation and genomic harmony: insights into allopolyploid evolution in marsh orchids (Dactylorhiza)

New Phytologist, Volume 250, Issue 1, Page 648-660, April 2026.
Summary Hybridization and polyploidy are major drivers of plant diversification, often accompanied by shifts in gene expression and genome composition. Small RNAs (smRNAs) are thought to influence such genomic changes, particularly through their interactions with transposable elements (TEs).

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

Protoplast‐Based Functional Genomics and Genome Editing: Progress, Challenges and Applications

Plant, Cell &Environment, Volume 49, Issue 4, Page 2183-2199, April 2026.
ABSTRACT Protoplast‐based systems provide a powerful and versatile platform for exploring how plants sense and respond to their environment. By enabling the direct delivery of proteins, DNA, and RNA into plant cells after cell wall removal, this approach facilitates precise molecular dissection of signaling, stress adaptation, and gene regulation ...

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

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

Advanced Science, Volume 13, Issue 14, 9 March 2026.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

Phylogenetic systematics of Juncaceae

American Journal of Botany, Volume 113, Issue 3, March 2026.
Abstract Premise Juncaceae has needed taxonomic revision for some time. Specifically, the genus Juncus s.l. is known to be paraphyletic because five small southern‐hemisphere genera have been shown repeatedly to be nested within it. In 2022, a new classification was proposed, based on phylogenies built from one nuclear and three plastid regions ...
