Data from: A genome-wide assessment of genetic diversity and population structure of Korean native cattle breeds
Background: The native cattle breeds are an important genetic resource for meat and milk production throughout Asia. In Asia cattle were domesticated around 10,000 years ago and in Korea cattle are being raised since 2000 B.C. There are three native breeds of cattle in Korea viz. Brown Hanwoo, Brindle Hanwoo and Jeju Black. While one of these breeds, Brown Hanwoo, is a part of a Food and Agricultural Organization and national genetic evaluation plans, others get little attention. This study is an effort to understand and provide a detailed insight into the population structure and genetic variability of the Korean cattle breeds along with other Asian breeds using various methods. In this study we report the genetic variation and structure of the Korean cattle breeds and their comparison with five other Asian cattle breeds along with a panel of animals from European taurine, African taurine and indicine cattle breeds. Results: Asian cattle were found to be least differentiated which reflects their recent history. Amongst the Asian breeds Hainan, which is an indicine breed, had the lowest gene diversity while Yanbian had the highest followed by Mongolian and Korean cattle. Amongst the Korean breeds Brown Hanwoo had the highest diversity followed by Brindle Hanwoo and Jeju Black. The genetic diversity in Asian cattle breeds was found comparable to the European taurines and more than the African taurines and Zebu cattle. Korean cattle breed, Brown Hanwoo was consistently found to be closer to Yanbian, a Chinese cattle breed. We found low divergence and moderate levels of genetic diversity among the native Korean breeds. Indicine introgression from Hainan was seen in other Asian breeds. From Europe, Limousin, Holstein and Hereford introgression was found in Asian breeds. Conclusions: In this study we provide a genome-wide insight into the genetic history of the native cattle breeds of Korea. The outcomes of this study will help in prioritization and designing of the conservation plans.
Data from: Is Hydroides dianthus (Verrill, 1873) really a Mediterranean native? Increased sampling in the eastern United States reveals enhanced genetic diversity
<p>The introduction of non-indigenous species (NIS) is a significant threat to marine biodiversity, facilitated by vectors such as shipping and aquaculture. <em>Hydroides dianthus,</em> a tubicolous polychaete worm, is known for its biofouling capabilities, impacting both shipping and aquaculture. Traditionally, the east coast of the United States has been considered the native range of <em>H. dianthus</em>. However, previous studies have suggested the Mediterranean region as the species' true native range based on higher genetic diversity. This study aims to re-evaluate the genetic diversity patterns of <em>H. dianthus</em> on the east coast of the United States by expanding the cytochrome c oxidase I (COI) dataset currently available for the species. Samples were collected from various locations on the east coast and analyzed using DNA barcoding. The results revealed a three-fold increase in haplotype diversity on the east coast compared to previous findings. A hierarchical AMOVA indicated significant genetic structuring between the Mediterranean and U.S. populations (ϕST = 0.51, P < 0.05). Despite a higher genetic diversity in the Mediterranean, this study highlights the variability of genetic diversity estimates and the challenges in using such metrics to delineate native ranges. Factors such as multiple introductions, genetic drift, and sampling bias can significantly alter genetic variability within populations. The findings suggest that the east coast's genetic diversity is likely underestimated and that more comprehensive data, including high-throughput genomic analyses and ecological studies, are needed to determine the native range of <em>H. dianthus</em> conclusively. This study underscores the complexity of using genetic data to trace the biogeography and invasion pathways of marine species.</p>

Metataxonomics 16S rDNA of maize bulk and rhizospheric soil samples with seed bacterization with Azospirillum brasilense Ab-V5 in a dilution-to-extinction of native microbial diversity
<p><strong>The beneficial plant-microbes association has been widely explored with the purpose of understanding the mechanisms involved in this interaction, in order to develop bioinoculants for agriculture aiming at sustainability and reduction of chemical inputs use. Plant growth promoting bacteria (PGPBs) have been reported as an interesting alternative to mineral fertilizers for a range of crops. The genus Azospirillum has shown potential in plant growth promotion for maize. However, the lack of holistic comprehension about PGPBs-plant-native soil microbiota can lead to inconsistency of results in field conditions. Recent ecological theories revealed that plant microbiomes are organized as microbial hubs with keystone species and helpers. The objective of this work is to characterize the microbial community associated with a commercial maize genotype (30A37PW) under influence of the potential keystone PGPB A. brasilense Ab-v5 to support the original development of a synthetic minimum microbiome including this strain as keystone for plant growth promotion. Aiming to understand the PGPB-plant-microbiome system, we conducted a greenhouse experiment in which the synergistic effect of Ab-V5 and soil native microbial community were evaluated through soil and rhizosphere metataxonomics, metagenomics and plant phenomics. Our results revealed that maize seed bacterization with the PGPB Ab-V5 promotes plant growth. This effect is boosted by the interaction with specific microbial groups present in the soil native community. The strain Ab-V5 persists in the maize rhizosphere until 25 days after sowing. In order to understand which microbial groups are important during the interaction Ab-V5-plant-native soil microbial community, 16S rDNA metataxonomics and metagenomics analysis will be conducted in maize soil and rhizosphere samples. This unprecedented omics approach for the holistic view of the complex system composed by inoculant-plant-microbiota and data integration will allow the development of new strategies for optimization of plant biostimulants recommendation with enhanced efficiency for establishment in the field. </strong></p>
