Mono- and Trivalent Ions around DNA: A Small-Angle Scattering Study of Competition and Interactions

open access: yes, 2008
The presence of small numbers of multivalent ions in DNA-containing solutions results in strong attractive forces between DNA strands. Despite the biological importance of this interaction, e.g., DNA condensation, its physical origin remains elusive ...

Fascinating single‐cell red algae: models for evolution and adaptation

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1424-1437, May 2026.
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

From living to fossil: ancestral state reconstruction of leaf architecture in extant Lauraceae and its relevance for the fossil record

open access: yesPalaeontology, Volume 69, Issue 3, May/June 2026.
Abstract Lauraceae are a tropical–subtropical angiosperm family that exhibit significant diversity and a rich fossil record, primarily of leaves found worldwide from the Cretaceous to the present. However, the taxonomic placement of many fossil leaves remains uncertain because of morphological convergence and limited variation in leaf characters among ...

Dissecting the Cell‐Type‐Specific Response to an Emerging Tobamovirus in Tomato Reveals Cultivar‐Dependent Involvement of Brassinosteroid Signalling

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 3106-3124, May 2026.
ABSTRACT Plant viruses drive widespread crop epidemics, yet the host plant responses across different cell types, particularly how these responses are influenced by cultivars with varying genetic backgrounds, including the presence of resistance (R) genes, remain poorly understood. Using tomato brown rugose fruit virus (ToBRFV) and two tomato cultivars,

Chemical Equilibrium Abundances in Brown Dwarf and Extrasolar Giant Planet Atmospheres

open access: yes, 1998
We calculate detailed chemical abundance profiles for a variety of brown dwarf and extrasolar giant planet atmosphere models, focusing in particular on Gliese 229B, and derive the systematics of the changes in the dominant reservoirs of the major ...

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

open access: yesPlant, Cell &Environment, Volume 49, Issue 5, Page 2654-2672, May 2026.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

Architectural and biochemical advances in understanding microbial CO2 concentrating mechanisms

open access: yesThe Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY CO2 concentrating mechanisms (CCMs) are ubiquitous in phototrophs. They are found in the micro as well as the macro world. Different domains of life have developed strikingly different approaches to concentrate inorganic carbon around Rubisco, the most prevalent enzyme on earth.
