Summary: In this study, an improved wild soybean chromosome segment substitution line (CSSL) population, SojaCSSLP5, was developed, which was genotyped through whole-genome resequencing to identify genetic changes from wild soybean to cultivated soybean. Using the SNPLDB-map, several candidate genes related to seed-coat color and days to flowering were identified and verified, demonstrating the efficiency of the CSSL population in identifying candidate wild vs. cultivated gene-alleles. The integration of parental DNA and RNA sequencing data provided a reliable platform for further research on genetic changes between wild and cultivated soybean.

Summary: Next-generation sequencing technology has revolutionized ecological and evolutionary genetics, enabling cost-effective identification of genome-wide variation. In this study, researchers developed a 50K SNP chip for the threatened species hihi by combining RAD-seq and WGS data, demonstrating its utility in identifying SNPs for genotyping and revealing high rates of linkage disequilibrium in the hihi genome, indicative of population bottleneck events.

Summary: This study identified a genomic region on chromosome 4 associated with coat color variation in Chinese Rex rabbits through genome sequencing and genome-wide association studies. The well-studied coat-color-associated ASIP gene was located within this region, confirming it as a putative causal gene affecting coat color variation in Chinese Rex rabbits.

Summary: This study found that seed coat heterosis in maize hybrids might be the result of the coordination between cell number and cell size. RNA-seq results showed significant changes in nonadditive genes between 0 day and 15 days, while the expression of additive genes did not differ significantly. Gene ontology and pathway enrichment analysis indicated that genes related to DNA replication, cell cycle regulation, circadian rhythms, and metabolite accumulation played a significant role in hybrid seed coat heterosis. These findings provide evidence for genes involved in hybrid seed coat heterosis.

Summary: This study investigated the role of GmFULc in regulating flowering time in Arabidopsis and found that it inhibits the transcriptional activity of TPL, leading to the up-regulation of FT, SOC1, and LFY genes for promoting early flowering. GmFULc's involvement in the molecular mechanism of flowering regulation highlights its importance in plant development.

Summary: This study aimed to identify genes associated with soybean seed quality by comparing the transcriptomes of soybean seeds with different seed coat colors. Through RNA-seq analysis and validation with real-time PCR, 318 differentially expressed genes were found in all cultivars. These genes are involved in pathways related to ethylene, lipid, brassinosteroid, lignin, and sulfur amino acid biosynthesis.

Summary: This study examined the phenotypic variability of eighteen soybean cultivars, and found significant differences in flowering, yield, and seed quality traits among different maturity groups. Late flowering cultivars had lower seed weight compared to early flowering cultivars. Protein content increased with maturity groups, while oil content decreased. There were negative correlations between protein and yield, oil, and sucrose. The study identified high-yielding short-duration soybean cultivars and cultivars with desirable industry traits such as high protein and oil content.

Summary: Bulk segregant analysis based on next generation resequencing (BSA-seq) was performed on 1551 soybean accessions with diverse worldwide origins to investigate the genetic basis of oil content. A total of 2030 genes were identified and 130 candidate genes, including Glyma.04G047000, were further identified for seed oil content. High oil alleles for these candidate genes can be used as selective markers for soybean breeding with high oil content.

Summary: The composition of white (JS 335) and black (Bhatt) soybean seed coats with different water permeability was studied. Phenols, tannins, proteins, trace elements, and metabolites were measured in the seed coats. The study found that the impermeable seed coat of Bhatt contained higher concentrations of phenols, tannins, proteins, Fe, and Cu. Furthermore, both genotypes had unique metabolites in their seed coats. Phenols were identified as the main compounds responsible for seed coat impermeability in Bhatt. This study provides a platform for further understanding of the function of each identified compound in seed coat permeability.

Summary: A study comparing high-lignin and low-lignin content rapeseed offspring found correlations between lignin content and seed coat thickness, with significantly higher expression of lignin pathway genes in high-lignin seed coats. Additionally, some hormone synthesis genes and transcription factors were differentially expressed in high-lignin lines, and genes related to the flavonoid pathway were strongly expressed.
