Cross incompatibility restricting genome exchange and diversification of primary gene pool in plants: challenges and opportunitiesNARA Subscribed
Key message Crop wild relatives provide essential genetic diversity for improving crop resilience; however, pre- and post-zygotic barriers often restrict interspecific hybridization. Recent approaches enable their effective use in crop improvement programs. Abstract Crop wild relatives (CWR), closely related wild taxa of cultivated crops, offer a wealth of genetic diversity essential for developing traits to help crops adapt t...
Tenacibaculosis, a disease caused by Tenacibaculum spp., is of concern in British Columbia (BC, Canada) due to the potential for interspecific transmission from Atlantic salmon ( Salmo salar L.) to Pacific salmon. However, the susceptibility of most Pacific salmonids remains unknown. In this study, Atlantic salmon post‐smolts were bath‐exposed to an Atlantic salmon‐derived BC isolate of Tenacibaculum maritimum (isolate 2.1C) a...
Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs WorldwideNARA Subscribed
Soil microbiomes are critical for ecosystem functioning, yet the global influences of climate and agricultural practices on their diversity and structure remain incompletely characterized. Here we analyzed 1921 soil samples from 33 countries worldwide across diverse biomes to assess how climate gradients and agricultural inputs, including pesticides and fertilizers, shape prokaryotic and fungal communities. We found that micro...
Main conclusion Almond trees prioritize C to yield rather than stem growth, and their overall lower NSC stores compared to forest trees may have consequences for resilience under environmental variability. Abstract Perennial tree crops store nonstructural carbohydrates (NSCs) as energy reserves that can be used to persist during both predictable periods of reduced activity like dormancy and more unpredictable periods associate...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
