Abstract High-throughput genotyping arrays provide a standardized resource for plant breeding communities that are useful breadth of applications including high-density genetic mapping, genome-wide association studies (GWAS), genomic selection (GS), complex trait dissection, and studying patterns diversity among cultivars wild accessions. We have developed the CottonSNP63K, an Illumina Infinium array containing assays 45,104 putative intraspecific single nucleotide polymorphism (SNP) markers...
In Chile, since January 2023, a sudden and pronounced increase in strandings mortality has been observed among South American (SA) sea lions (Otaria flavescens), prompting significant concern. Simultaneously, an outbreak of highly pathogenic avian influenza H5N1 (HPAIV H5N1) species emerged December 2022. To investigate the cause this unexpected mortality, we conducted comprehensive epidemiological pathologic study. One hundred sixty-nine SA were sampled to ascertain their HPAIV status,...
Genetic linkage maps play fundamental roles in understanding genome structure, explaining formation events during evolution, and discovering the genetic bases of important traits. A high-density cotton (Gossypium spp.) map was developed using representative sets simple sequence repeat (SSR) first public set single nucleotide polymorphism (SNP) markers to genotype 186 recombinant inbred lines (RILs) derived from an interspecific cross between Gossypium hirsutum L. (TM-1) G. barbadense (3-79)....
H5N1 highly pathogenic avian influenza viruses (HPAIV) emerged in wild birds Chile December 2022 and spilled over into poultry, marine mammals, one human. Between 9, - March 14, 2023, a coordinated government/academic response detected HPAIV by real-time RT-PCR 8.5% (412/4735) of samples from 23 3 mammal orders. Whole-genome sequences obtained 77 8 mammals revealed that all Chilean belong to lineage 2.3.4.4b cluster monophyletically with Peru, indicating single introduction North America...
Highly pathogenic H5N1 avian influenza viruses (HPAIV) belonging to lineage 2.3.4.4b emerged in Chile December 2022, leading mass mortality events wild birds, poultry, and marine mammals one human case. We detected HPAIV 7,33% (714/9745) of cases between 2022-April 2023 sequenced 177 virus genomes from mammals, a human, birds spanning >3800 km Chilean coastline. were closely related Peru's outbreak, consistent with north-to-south spread down the Pacific One nine mammal had rare PB2 D701N...
Chromosome identities were assigned to 15 linkage groups of the RFLP joinmap developed from four intraspecific cotton (Gossypium hirsutum L.) populations with different genetic backgrounds (Acala, Delta, and Texas Plains). The chromosomes by deficiency analysis probes in previously published joinmap, based on genomic DNA hypoaneuploid chromosome substitution lines. These findings integrated QTL identification for multiple fiber yield traits. Overall results revealed presence 63 QTLs five A...
The Cotton Microsatellite Database (CMD) http://www.cottonssr.org is a curated and integrated web-based relational database providing centralized access to publicly available cotton microsatellites, an invaluable resource for basic applied research in breeding. At present CMD contains publication, sequence, primer, mapping homology data nine major microsatellite projects, collectively representing 5,484 microsatellites. In addition, displays three of the projects that have been screened...
Cotton germplasm resources contain beneficial alleles that can be exploited to develop adapted emerging environmental and climate conditions. Accessions lines have traditionally been characterized based on phenotypes, but phenotypic profiles are limited by the cost, time, space required make visual observations measurements. With advances in molecular genetic methods, genotypic increasingly able identify differences among accessions due larger number of markers measured. A combination both...
f. sp. vasinfectum (FOV) race 4 (FOV4) is a highly pathogenic soil-borne fungus responsible for Fusarium wilt in cotton (
Abstract Molecular markers such as simple sequence repeats (SSR) are a useful tool for characterizing genetic diversity of Gossypium germplasm. Genetic profiles by DNA fingerprinting cotton accessions can only be compared among different collections if common set molecular used laboratories and/or research projects. Herein, we propose and report core 105 SSR with wide genome coverage at least four evenly distributed per chromosome the 26 tetraploid chromosomes. The marker represents efforts...
Many Fusarium oxysporum formae speciales produce small, infection-dependent effector proteins called “secreted in xylem” (SIX) proteins. These are secreted into the xylem of a plant during infection process and thought to promote virulence. In this study, collection isolates composed primarily different races f. sp. vasinfectum (FOV) was screened for presence 14 SIX genes ( SIX1 SIX14). Our results showed that some most virulent FOV races, FOV4 FOV7, share common effector: SIX9. This is...
