“…The dimensions (width and length) of the peanuts were determined using a Vernier Caliper (Shanghai Tool Factory Co., Ltd., Shanghai, China) (Yu, Liu, Erasmus, et al, 2020). The width (mm) and the length (mm) of each peanut kernel are respectively the crosswise and the longitudinal distance of the mature seed (Jiang, Duan, & Ren, 2006).…”

“…In eukaryotic cells, these proteins are involved in the transport of acyl-CoA esters and the formation and maintenance of the cytosolic acyl-CoA pool, thereby contributing to the regulation of lipid metabolism ( Guo et al, 2017 ). On the basis of principal component analysis, Yu et al (2020) found that the sucrose content in peanut kernels was negatively correlated with fat content. In the present study, we detected significant differences between the two parents with respect to the expression of Arahy.Y2LWD9 during different stages of development, and that overall, there was an upward trend in expression with growth progression, which was opposite to the accumulation of sucrose.…”

As an important factor affecting the edible quality of peanut kernels, sucrose content is a complex quantitative trait regulated by multiple factors. In this study, an F2 segregating population and a recombinant inbred line (RIL) population, derived from a cross between the high sucrose content variety Jihuatian 1 and the low sucrose content line PI478819, were used as materials to map a quantitative trait locus (QTL) associated with sucrose content in peanut kernels. Four QTLs were initially located on chromosomes A03 and A06 based on BSA-seq technology, and multiple kompetitive allele-specific PCR markers were developed based on single-nucleotide polymorphisms (SNPs) in the intervals. The markers were genotyped in the RIL population and finely mapped to a stable QTL, qSUCA06, located on chromosome A06 within a 0.29-Mb physical genomic interval (112367085–112662675 bp), which accounted for 31.95%–41.05% of the phenotypic variance explained. SNP and insertion/deletion annotations were performed on genes in the candidate interval, and having screened out those genes with mutations in exons, candidate genes were verified by qRT-PCR. The results revealed that Arahy.Y2LWD9 may be the main gene regulating sucrose content. The QTL identified in this study will not only contribute to marker-assisted breeding for improvement of peanut sucrose content but also paves the way for identifying gene function.

“…However, compared with the control treatment, the oleic acid/linoleic acid ratio of peanut grains decreased under waterlogging stress, which indicated that the storage of peanut oil or other peanut products produced by the grains harvested after waterlogging decreased. Peanut grains contain eight kinds of essential amino acids (Yu et al, 2020), especially glutamic and aspartic, advancing the development of brain cells and enhancing memory (Wang et al, 2017; Yu et al, 2021). Here, waterlogging stress decreased the aspartic, glutamic, alanine, isoleucine, phenylalanine and lysine content.…”

To investigate the effects of waterlogging stress on grain nutritional quality and pod yield, peanut plants were waterlogged for 3 and 6 days at 7, 14, 21, 28, 35, 42, 49, 56 and 63 days after gynophores touched the ground in 2019 and 2020. Results revealed that compared with the control treatment, the oil and starch content in grain increased, while crude protein and soluble sugar content decreased under waterlogging. Waterlogging stress increased the unsaturated fatty acids content but decreased the saturated fatty acids, essential amino acids, non-essential amino acids and total amino acids content. In addition, waterlogging stress decreased the total pod number per plant by 6.78%-49.33%, 100-pod weight by 1.11%-14.08% and 100-grain weight by 1.85%-16.41%, which caused a 34.33%-55.90% reduction in pod yield per plant.After the gynophore touched the ground for 7 days, waterlogging had a greater negative effect on grain nutritional quality, and longer waterlogging duration led to greater yield reduction. In summary, waterlogging stress caused peanut yield reduction and grain quality deterioration.
