Morphology of the megaspore Lagenoisporites magnus (Chi and Hills 1976) Candilier et al. (1982), from the Carboniferous (lower Mississippian: mid-upper Tournaisian) of Bolivia

Anais da Academia Brasileira de Ciências
: The morphology and structure of megaspores assigned to Lagenoisporites magnus from the Toregua Formation, Retama Group, mid-upper Tournaisian of Bolivia were studied. The analysis was performed with light, fluorescence and scanning electron microscopy.

RING E3 ligase SNIPER8 functions redundantly with three close homologs to regulate the turnover of transcriptional co‐repressor TPR1

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis E3 ligase SNIPER8 negatively regulates immunity by promoting ubiquitination and proteasomal degradation of the transcriptional corepressor TOPLESS‐RELATED1, limiting excessive immune responses, maintaining immune homeostasis, and balancing defense activation and normal plant growth.

Engineered Yarrowia lipolytica inducing gene silencing confers control ability against gray mold in plants

Journal of Integrative Plant Biology, EarlyView.
Engineered the plant‐colonizing yeast Yarrowia lipolytica to produce and deliver double‐stranded RNAs targeting key genes of the gray mold fungus Botrytis cinerea produced a ‘living factory’ that continuously synthesizes and releases gene‐silencing molecules on plant surfaces, effectively suppressing the pathogen.

Dive surveys and eDNA detect contrasting macroalgal community composition in Nova Scotia, Canada

Journal of Phycology, EarlyView.
Abstract Morphological identification of macroalgae can be time‐consuming and species may be difficult to observe, collect, or identify, preventing detailed study on the distribution and ecology of many species. The use of eDNA in species surveillance and biodiversity assessments has gained considerable traction in studying macroalgae, as it provides ...

Giant kelp (Macrocystis pyrifera) gametophytes grow endophytically in red macroalgae: Implications for kelp restoration

Journal of Phycology, EarlyView.
Abstract Giant kelp (Macrocystis pyrifera) forests have declined by 95% in Australia since the 1970s due to climate change. Despite expanding restoration efforts, long‐term recovery is still lacking. Factors influencing recruitment by the microscopic gametophyte phase may represent a key mechanism underpinning the successful recovery and restoration of

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Genomic analyses of giant kelp reveal restricted connectivity across the Southern Hemisphere and striking diversity in Aotearoa (New Zealand)

Journal of Phycology, EarlyView.
Abstract The macroalga Macrocystis pyrifera (“giant” or “bladder” kelp) plays a vital role in cold‐temperate marine ecosystems but faces increasing threats from ongoing environmental change. Understanding its population diversity and connectivity is essential for predicting future range shifts and assessing the ecological consequences of such shifts in

Next Generation Smart Implant Surfaces: Engineering Multifunctional Antimicrobial, Immunomodulatory and Regenerative Interfaces

Journal of Periodontal Research, EarlyView.
Natural‐inspired nano‐textured implant surfaces can be functionalised to modulate macrophage polarisation and local immune responses. This bioactive control promotes improved tissue integration and healing outcomes. ABSTRACT Dental implants rely on a stable and functional interface between the implant surface, surrounding tissues, and the oral ...

Characterization of Sec14 Domain–Containing Proteins in the Malaria Parasite Plasmodium falciparum

Molecular Microbiology, EarlyView.
During asexual blood‐stage development, P. falciparum Sec14 proteins display distinct localizations suggesting specialized roles in lipid exchange. PfSec14‐1 initially localizes to the nucleus before moving to the ER and Golgi alongside PfSec14‐4 during schizogony.
