Ontogenia de los estróbilos, desarrollo de los esporangios y esporogénesis de Equisetum giganteum (Equisetaceae) en los Andes de Colombia

Revista de Biología Tropical, 2011
Estudios sobre la ontogenia del estróbilo, los esporangios y la biología reproductiva de Equisetum son escasos, por lo tanto, para la especie E. giganteum, se estudiaron estos aspectos en especímenes recolectados a orillas del Río Frío, Santander ...

The Influence of Cu2+ Salts on the Enzymatic Activity of Aspergillus niger Clinical Isolates [PDF]

Учёные записки Казанского университета: Серия Естественные науки, 2015
The influence of heavy metals on the enzymatic activity of Aspergillus niger is analyzed. The effects of Cu2+ on the growth rate, antimycotic resistance, as well as amylolytic and lipolytic activity of various clinical isolates of Aspergillus niger are ...

Foundation species loss alters algal community structure and dynamics at a trailing range edge

Journal of Ecology, Volume 113, Issue 12, Page 3858-3872, December 2025.
These findings show the indirect effects of climate‐driven population loss, through changes in ecological interactions such as competition, that can propagate through entire communities. Given kelp underpin the wider temperate reef food web, this will likely have serious knock‐on consequences at the ecosystem level.

Cytohistological Analyses of Mega-sporogenesis and Gametogenesis in Ovules of Limonium spp.

Bio-Protocol, 2016
Limonium spp. are known to have sexual and apomixis (asexual reproduction through seeds) reproductive modes. Here, we present dissection protocol developed for ovules of Limonium spp. using differential interference contrast (DIC) microscopy.

Multiple hybrid zones involving four Cardamine species and their triploid progeny: watching allopolyploid speciation in action?

New Phytologist, Volume 248, Issue 5, Page 2616-2635, December 2025.
Summary Hybrid zones provide excellent opportunities to study evolutionary processes linked to interspecific gene flow, including introgression, genetic erosion, polyploid establishment, and speciation. The genus Cardamine (Brassicaceae) serves as an excellent model for polyploid evolution, including one of the few well‐documented neo‐allopolyploid ...

Transcriptome Profiling of Resistance Gene Analogs in Soybean's Cross‐Tolerance to Water Limitation and Rust Stress

Food and Energy Security, Volume 14, Issue 5, September/October 2025.
ABSTRACT Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is the most destructive foliar disease of soybean, with yield losses up to 90%. With climate change intensifying drought and expanding disease incidence, it is critical to understand how combined abiotic and biotic stresses influence plant defense.

Seasonal and Spatial Variation in the Growth, Biomass Production, Mortality and Potential Blue Carbon Production of Golden Kelp (Ecklonia radiata) Off Eastern Australia

Austral Ecology, Volume 50, Issue 9, September 2025.
ABSTRACT Kelp removes carbon from the oceans as it grows, with the potential for long‐term removal of this ‘blue carbon’ through the sequestration of kelp detritus in deep offshore sediments and waters. However, understanding the magnitude of kelp's blue carbon potential requires more detailed information about kelp growth, biomass production, and ...

Morphological and ultrastructural variations in Scliizjaea pectinata (Schizaeaceae: Pteridophyta)

Bothalia: African Biodiversity & Conservation, 1994
Schizaea pectinata (L.) Sw. was collected from the extreme ends of its geographical range in South Africa for a study of sporangial development, sporogenesis and tapetal organisation.

Translation initiation in plants: roles and implications beyond protein synthesis

Biologia Plantarum, 2015
Protein synthesis is a ubiquitous and essential process in all organisms, including plants. It is primarily regulated at translation initiation stage which is mediated through a number of translation initiation factors (eIFs).
