A Century of Understanding and Harnessing Heterosis

Plant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Water Deficit Does Not Compromise the Resistance to Insect Herbivores in Plants Associated With Fungal Endophytes Able to Produce Bioactive Alkaloids

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants growing in nature are exposed to multiple abiotic and biotic stressors that sometimes occur sequentially. We hypothesised that drought will not compromise the resistance levels to herbivores when plants are associated with Epichloë endophytes able to produce bioactive alkaloids. Lolium perenne plants without (nil) and with Epichloë LpTG‐

Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

Photochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...

Understanding the Reproductive Life Planning Experiences of People With Disabilities in Ontario, Canada: A Qualitative Exploration

Perspectives on Sexual and Reproductive Health, EarlyView.
ABSTRACT Introduction Reproductive life planning can be a valuable component of reproductive health promotion. However, little is known about attitudes, desires, and intentions regarding pregnancy among people with disabilities. This exploratory qualitative study aimed to understand the reproductive life planning experiences of women and gender‐diverse

A pellet‐based approach for moss biocrust inoculation: high establishment under laboratory conditions, challenges in the field

Restoration Ecology, EarlyView.
Abstract Introduction Biological soil crusts (biocrusts) are key components of soil ecosystems and promising tools for ecological restoration. Mosses, as important biocrust constituents, contribute to ecosystem functioning but often fail to establish after inoculation due to harsh environmental constraints.
