Why Self-fertilizing Plants Still Exist in Wild Populations: Diversity Assurance through Stress-Induced Male Sterility May Promote Selective Outcrossing and Recombination
Climate change creates challenges for wild species, but plants have survived and adapted
to similar changes in their evolutionary past. Most plants were originally outcrossing, one theoretical
genetic reason being that ...
Diversity analysis of 80,000 wheat accessions reveals consequences and opportunities of selection footprints
Undomesticated wild species, crop wild relatives, and landraces represent sources of variation for wheat improvement to address challenges from climate change and the growing human population. Here, we study 56,342 ...
Root-omics for drought tolerance in cool-season grain legumes
Root traits can be exploited to increase the physiological efficiency of crop water use under drought. Root length, root hairs, root branching, root diameter, and root proliferation rate are genetically defined traits that ...
Litter decay in rangeland sites with varying history of human disturbance: a study with Hazargangi Chiltan mountain
Hazarganji Chiltan National Park in Balochistan, Pakistan was established in 1980 and the protected area was further extended in 1998. Large area of this mountain is still open for unmanaged human disturbances such as ...
Seroprevalence of anti‐Mycobacterium avium subsp. paratuberculosis antibodies in female sheep in Tunisia
Paratuberculosis (Ptb) is a widespread chronic infection caused by Mycobacterium avium subsp. paratuberculosis (Map) that affects both domestic and wild ruminants. Most of the studies focused on cattle while, the prevalence ...
Phenotypic evaluation of elite spring bread wheat genotypes for hybrid potential traits
Wheat breeding has significantly contributed
to enhancing yield potential and stability.
However, one of the most promising technologies for
further sustainable yield increases, hybrid wheat, is
still limited due to lack ...
Field synchronization of Ethiopian Highland sheep for fixed time artificial insemination: improvement of conception rate with a double injection of prostaglandin at 11 days
The study investigated, for fixed time artificially inseminated (AI) Menz ewes in field trials, the reproductive
performance of prostaglandin-based treatments simultaneously to the standard ‘P4+eCG’ protocol. A total
of ...
Genome-Wide Analysis Revealed Homozygosity and Demographic History of Five Chinese Sheep Breeds Adapted to Di erent Environments
Homozygosity of long sequence genotypes are a result of parents transmitting identical
haplotypes, which can be used to estimate their auto-zygosity. Therefore, we used high-density SNP
Chip data to characterize the ...
Participatory identification of breeding objective traits and selection criteria for indigenous goat of the pastoral communities in Ethiopia
Structured questionnaire, own-flock rankings and group discussions were undertaken to assess goat breeding practices and to identify traits of interest for genetic improvement of pastoral goats. Four pastoral villages in ...
Assessing technological change in agri-food systems of the Global South: A review of adoption-impact studies in wheat
Agricultural research-and-development (R&D) systems generate and disseminate new technologies, aiming to enhance crop and livestock production sustainably. Adoption-impact studies analyze farmer acceptance of these innovations ...
