Rapid Clearance of Tetracapsuloides bryosalmonae Spores by Freshwater Sponge Ephydatia muelleri: Potential Implications for Controlling Proliferative Kidney Disease in Salmonids

Journal of Fish Diseases, Volume 49, Issue 6, June 2026.
ABSTRACT Host–parasite interactions are influenced by both abiotic and biotic factors. While abiotic drivers, particularly temperature, have received considerable attention in recent years due to global climate change, the role of biotic factors remains comparatively underexplored.

VPS13 has an important role in female germline development in Arabidopsis

The Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY The female germline precursor cell, known as the megaspore mother cell (MMC), differentiates and develops within the ovule through a complex genetic network, including post‐transcriptional and translational regulation mediated by miRNA. A key player in restricting MMC development to a single cell within the nucellus is the AUXIN RESPONSE FACTOR

A unique class of Zn2+-binding serine-based PBPs underlies cephalosporin resistance and sporogenesis in Clostridioides difficile

Nature Communications, 2022
Antibiotics of the β-lactam class inhibit bacterial cell wall synthesis by targeting penicillin-binding proteins (PBPs). Here, Sacco et al. study the four PBPs present in the pathogen C.

Reprogramming of Histone H3 Lysine Methylation During Plant Sexual Reproduction

Frontiers in Plant Science, 2021
Plants undergo extensive reprogramming of chromatin status during sexual reproduction, a process vital to cell specification and pluri- or totipotency establishment.

Historical data reveal extirpation of foundation species and kelp forest community deborealization in a coastal hotspot

Ecological Applications, Volume 36, Issue 3, April 2026.
Abstract Climate change is restructuring ecological communities globally, yet the impacts are often underestimated or poorly resolved due to the lack of historical baselines. In temperate oceans, biologically diverse and socioeconomically important kelp forests are the marine ecosystem most threatened by climate change.

Embryogeny and Sporogenesis in Reboulia Hemisphaerica [PDF]

Botanical Gazette, 1921
1. The embryo of Reboulia develops without the formation of an octant stage characteristic of certain other Marchantiaceae. 2. The first transverse wall in the fertilized egg separates the cell which is to form the foot from that which is to form the seta and capsule.

The hard and soft of it: The role of substrate in patterns of phase dominance and phenology in Gracilaria vermiculophylla

Journal of Phycology, Volume 62, Issue 2, Page 377-399, April 2026.
Abstract Despite the importance of the seasonal timing of events in the life cycle for understanding population dynamics, we lack information on the phenology of most macroalgal species. The red macroalga Gracilaria vermiculophylla has become common in both hard‐ and soft‐bottom habitats following its invasion throughout the Northern Hemisphere.

Exploring the Cultivation of Ulva intestinalis in Low-Salinity Environments of the Baltic Sea

Oceans
Ulva intestinalis holds promise for sustainable aquaculture in the Baltic Sea, but success has so far been limited by high environmental variability.

Chromatin dynamics during plant sexual reproduction

Frontiers in Plant Science, 2014
Plants have the remarkable ability to establish new cell fates throughout their life cycle, by contrast to most animals that define all cell lineages during embryogenesis.
