Aflatoxin is a group of polyketide-derived carcinogenic and mutagenic secondary metabolites produced by Aspergillus flavus that negatively impact global food security and threaten the health of both humans and livestock. Aflatoxin biosynthesis is strongly affected by the fungal developmental stage, cultivation conditions, and environmental stress. In this study, a novel float culture method was used to examine the direct responses of the A.

Article Synopsis
  • The study examines the environmental risks of gene flow from genetically modified (GM) crops, specifically glufosinate-ammonium-resistant Brassica napus, to its conventional relatives in smallholder farming systems in Korea.
  • Results showed that hybridization rates were low, with the highest frequency occurring at a distance of 2 meters and decreasing significantly with distance; gene flow to related species like B. juncea was minimal.
  • The findings suggest that while long-distance gene flow is unlikely, there is a potential risk of gene flow between closely adjacent fields in these farming systems.

Article Synopsis
  • This study investigates gene flow from genetically modified (GM) herbicide-resistant Brassica napus to its wild relatives through wind and bee pollination, which raises ecological concerns in agricultural settings.* -
  • Results show that the maximum gene flow to male sterile (MS) B. napus and B. juncea decreased significantly with distance from HR B. napus, with positive percentages only within close proximity; for MS R. sativus, there was no observed gene flow.* -
  • The findings indicate that small donor plots favor insect pollination over wind, highlighting the need for better management of gene flow to mitigate environmental risks.*

Single nucleotide polymorphisms (SNPs) play important roles as molecular markers in plant genomics and breeding studies. Although onion ( L.) is an important crop globally, relatively few molecular marker resources have been reported due to its large genome and high heterozygosity.

Prairie cordgrass (Spartina pectinata), a perennial C4 grass native to the North American prairie, has several distinctive characteristics that potentially make it a model crop for production in stressful environments. However, little is known about the transcriptome dynamics of prairie cordgrass despite its unique freezing stress tolerance. Therefore, the purpose of this work was to explore the transcriptome dynamics of prairie cordgrass in response to freezing stress at -5°C for 5 min and 30 min.

Single nucleotide polymorphisms (SNPs) are one of the most abundant DNA variants found in plant genomes and are highly efficient when comparing genome and transcriptome sequences. SNP marker analysis can be used to analyze genetic diversity, create genetic maps, and utilize marker-assisted selection breeding in many crop species. In order to utilize these technologies, one must first identify and validate putative SNPs.

The cp genome size is similar in three accessions, ranging from 139 846 bp to 139 860 bp. All three genomes have two inverted repeats (IR) of 22 748 bp per each IR with a large single copy (LSC) region of 81 833-81 844 bp and a small single copy (SSC) region of 12 517-12 520 bp.

Interspecific hybrids often increase the levels of heterozygosity and hybrid vigor, but some interspecific hybrid seeds are aborted shortly after fertilization. The mechanism behind this postzygotic seed abortion is poorly understood. Here, we report genome-wide analysis of allelic expression changes in developing siliques and seeds in three F1 interspecific crosses between Arabidopsis thaliana (Col, Ler, or C24) and Arabidopsis arenosa.

Echinochloa is a major weed that grows almost everywhere in farmed land. This high prevalence results from its high adaptability to various water conditions, including upland and paddy fields, and its ability to grow in a wide range of climates, ranging from tropical to temperate regions. Three Echinochloa crus-galli accessions (EC-SNU1, EC-SNU2, and EC-SNU3) collected in Korea have shown diversity in their responses to flooding, with EC-SNU1 exhibiting the greatest growth among three accessions.

Background: The morphogenesis of single-celled cotton fiber includes extreme elongation and staged cell wall differentiation. Designing strategies for improving cotton fiber for textiles and other uses relies on uncovering the related regulatory mechanisms. In this research we compared the transcriptomes and metabolomes of two Gossypium genotypes, Gossypium barbadense cv Phytogen 800 and G.

Background: The honey bee is an important model system for increasing understanding of molecular and neural mechanisms underlying social behaviors relevant to the agricultural industry and basic science. The western honey bee, Apis mellifera, has served as a model species, and its genome sequence has been published. In contrast, the genome of the Asian honey bee, Apis cerana, has not yet been sequenced.

With the next generation sequencing technology, RNA-Seq (RNA sequencing) becomes one of the most powerful tools in quantification of global transcriptomes, discovery of new transcripts and alternative isoforms, as well as detection of single nucleotide polymorphisms (SNPs). RNA-Seq is advantageous over hybridization-based gene quantification methods: (1) it does not require prior information about genomic sequences, (2) it avoids high background problem caused by cross-hybridization, and (3) it is highly sensitive and avoids background and saturation of signals; and finally it is capable of detecting allelic expression differences in hybrids and allopolyploids. We used the RNA-Seq method to determine the genome-wide transcriptome changes in Arabidopsis allotetraploids and their parents, A.
