Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

One‐step generation of heritable mitochondrial DNA multiplex‐engineered rats using DddA‐derived cytosine base editor

Animal Models and Experimental Medicine, EarlyView.
We established that mixed DdCBE microinjection is an efficient, heritable, and precise strategy for generating multiplex mtDNA mutant rats. This advancement significantly expands the utility of DdCBEs for mitochondrial disease modeling, providing a robust platform for exploring the pathogenic mechanisms of complex mtDNA mutations and developing ...

Maternal‐Fetal Administration of Risdiplam Partially Rescues the SMNΔ7 Mouse Model of Spinal Muscular Atrophy

Annals of Neurology, EarlyView.
Objective Spinal muscular atrophy (SMA) is caused by deletions or mutations in the survival motor neuron 1 (SMN1) gene and subsequent reduction in the expression of survival motor neuron (SMN) protein. The disease is characterized by degeneration of α motor neurons and subsequent muscle atrophy.

Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus

Animal Research and One Health, EarlyView.
The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable
