Researchers modeled gene drive dynamics in plants and found that seed banks can hinder the spread of genetic changes. The simulations suggest that proper consideration is needed to mitigate the impact of stored seeds on the gene drive's success.
The project addresses data fragmentation in biodiversity sciences, connecting fragmented data to tackle biodiversity loss, climate change, and emerging public health threats. A collaborative effort developed five cross-cutting themes to guide data integration, emphasizing the need for large-scale community action.
A fungal pathogen is causing cassava witches' broom disease to spread rapidly in Brazil and French Guiana, impacting food security and livelihoods. Researchers are racing against time to understand the extent of the threat and find a way to treat or prevent the disease.
A study by the Open Wild Wheat Consortium explains how Aegilops tauschii, a wild grass, contributed to the genetic diversity of bread wheat, enabling its rapid spread across different climates. This hybridization event allowed humans to settle down and form societies.
A study found that chromatin's spatial structure plays a key role in the evolution of social behavior in dogs. The researchers examined an intronic section of the GTF2I gene, which influences chromatin's spatial structure and causes differences in gene expression.
Genetic analysis reveals that ancient Indigenous people brought the native tuber to southern Utah, adding to the list of culturally significant plant species domesticated in the Southwestern U.S. The Four Corners potato was transported and cultivated by various tribes, including Pueblo and Apache communities.
The study found that APOE4 carriers have elevated LDL cholesterol levels, increasing their risk of developing subclinical atherosclerosis. In contrast, APOE2 carriers have lower cholesterol and reduced atherosclerosis prevalence.
A large-scale ancient human gene bank analysis revealed that genetic variants increasing MS risk were introduced by sheep and cattle herders 5,000 years ago. This finding explains the North-South Gradient of MS prevalence in Europe.
Researchers using genetic databases study the interaction between biological forces and social environments to better understand complex behaviors. By analyzing massive banks of genetic data, scientists can clarify the nuances of human behavior and improve social science research.
Researchers discovered a new genetic variation in old wheat varieties that enhances yield potential and resistance to yellow rust, potentially replacing current elite varieties. The findings also reveal possible new gene variants for resistance to yellow rust infestation, paving the way for more sustainable farming practices.
The EU's new AGENT research project aims to establish a global network of actively cooperating gene banks and convert them into digital resource centers. The project seeks to standardize gene bank management and verification, making plant genetic resources more accessible to researchers and breeders worldwide.
The wild relatives of chile peppers, pumpkins, carrots, and lettuce are imperiled, with many species not well-represented in gene banks or protected areas. These plants possess genes that can help their cultivated cousins withstand harsh climate conditions.
Researchers at Leibniz Institute of Plant Genetics and Crop Plant Research analyzed historical phenotypic data from the Federal Ex situ Gene Bank to develop statistical models leveraging maximal information from available datasets. The study provides blueprint strategies for correlated dataset preparation, complementing passport inform...
Gene banks are shifting to bioinformatics and big data analytics to enhance biodiversity preservation. Three major challenges arise: tracking accessions, avoiding duplications, and maintaining genetic integrity. A genomic-driven approach can address these issues by utilizing genotypic information.
Scientists at the University of Birmingham have identified 'hotspots' around the globe where crop wild relatives can be conserved to secure future global food resources. The highest concentration of these species is found in the Middle East's Fertile Crescent, threatening their survival due to climate change and conflict.
A team of researchers has developed a novel method to search gene sequences and identify similar proteins across different kingdoms of life. They found that Actinobacteria, a group of single membrane bacteria, is the last universal common ancestor of all living species.
The Global Crop Diversity Trust is rapidly reviving ailing seed samples from 46 countries to preserve genetic traits vital to maintaining global food security. The effort, which includes 100,000 different crop varieties, aims to prevent extinction of staple crops like rice, maize, and wheat.
The NIH has awarded a $6 million grant to researchers at UCLA to expand the Autism Genetic Resource Exchange (AGRE) gene bank and gather more information on autism. The study aims to identify genetic vulnerabilities in individuals with autism, which may lead to new treatments and therapies.
The team designed a unique mathematical system for analyzing genetic data based on a computer algorithm that clusters information into relevant categories. The algorithm mimics unassisted learning, categorizing tissue samples into separate clusters according to their gene expression profiles.
The consortium aims to collect medical information and genetic material from 400 families nationwide with AS to identify additional genes associated with its pathogenesis. Researchers will conduct genome-wide searches and map genes linked to AS outside of the MHC.
Researchers successfully transferred a normal human beta globin gene into mice bone marrow cells, achieving long-term expression and high levels of production. This breakthrough holds promise for the treatment of sickle cell disease and beta thalassemia.
Researchers at Cornell University have developed a way to increase food production in crops by using wild plant genes. By combining domesticated and wild gene varieties, they observed significant improvements in grain yield, with some increases of up to 48%.
