Arachis monticola (2n = 4x 40) is the only allotetraploid wild peanut within genus and section, with an AABB-type genome of ∼2.7 Gb in size. The AA-type subgenome derived from diploid duranensis, BB-type ipaensis. A. regarded either as direct progenitor cultivated or introgressive derivative between species. large polyploidy structure enormous nearly identical regions make assembly chromosomal pseudomolecules very challenging.

Cadmium (Cd) pollution significantly hampers cleaner production of peanut (Arachis hypogaea L.). Therefore, exploring tolerance mechanisms to Cd stress and breeding low-Cd cultivars are urgently needed require intense efforts.

Then, a total 17,338 high-quality single nucleotide polymorphisms (SNPs) in whole genome revealed. Eleven subsequently analyzed genome-wide association studies (GWAS). Candidate...
Herein, the effect of carbon nanodots (CDs) on stress resistance peanuts has been studied. It is found that stress-resistance ability peanut plants can be enhanced significantly when cultivated in CD aqueous solution with optimal concentration. Because increased ability, growth boosted, and output by about 9%. Confocal fluorescence images showed CDs transferred from roots to leaves through xylem vessels plants. The existence hydrophilic radical groups surface may result largely retaining...

Like many important crops, peanut is a polyploid that underwent polyploidization, evolution, and domestication. The wild allotetraploid species Arachis monticola (A. monticola) an unique link from the diploid to cultivated tetraploid in lineage. However, little known about A. its role evolution domestication of this crop. A fully annotated sequence ≈2.6 Gb genome comparative genomics reported. Genomic reconstruction 17 diploids AA, BB, EE, KK, CC groups 30 tetraploids demonstrates...
Abstract Background Long noncoding RNAs (lncRNAs) have several known functions involving various biological regulatory processes in plant. However, the possible roles of lncRNAs during peanut seed development not been fully explored. Results In this study, two recombinant inbred lines (RIL 8 ) that differ size were used to investigate comprehensive lncRNA profiles derived from at 15 and 35 days after flowering (DAF). We identified a total 9388 4037 novel lncRNAs, which 1437 differentially...
Pod size is a key agronomic trait that greatly determines peanut yield, the regulatory genes and molecular mechanisms controlling pod are still unclear. Here, we used quantitative locus analysis to identify regulator, POD SIZE/WEIGHT1 (PSW1), characterized associated gene protein. PSW1 encoded leucine-rich repeat receptor-like kinase (LRR-RLK) positively regulated stemness. Mechanistically, this allele harbouring 12-bp insertion in promoter point mutation coding region of causing...
Absract Peanut ( Arachis hypogaea L .) is an important oilseed and cash crop worldwide. Wild spp. are potental sources of novel genes for the genetic improvement cultivated peanut. Understanding relationships with peanut efficient use wild species in breeding programmes. However, this genus, only a few resources have been explored so far. In study, new chloroplast genomic developed genus based on whole genomes from seven that were sequenced using next-generation sequencing technologies. The...
Peanut (Arachis hypogea L.) bacterial wilt (BW) is a devastating disease caused by Ralstonia solanacearum that results in severe yield and quality losses. Plant defensins are short cysteine-rich peptides with antimicrobial activity. The role of defensin genes (AhDef) peanut unclear. A genome-wide investigation AhDef was undertaken, 12 identified were classified into two groups containing the gamma-thionin domain formed four disulfide pairs: Cys1-Cys8, Cys2-Cys5, Cys3-Cys6, Cys4-Cys7. In...
Abstract Background Three-dimensional (3D) chromatin organization provides a critical foundation to investigate gene expression regulation and cellular homeostasis. Results Here, we present the first 3D genome architecture maps in wild type mutant allotetraploid peanut lines, which illustrate A/B compartments, topologically associated domains (TADs), widespread interactions. Most chromosomal arms (52.3%) have active regions (A compartments) with relatively high density transcriptional...
Peanut (Arachis hypogaea L.) is one of the most important oil crops in world due to its lipid-rich seeds. Lipid accumulation and degradation play crucial roles peanut seed maturation seedling establishment, respectively. Here, we utilized lipidomics transcriptomics comprehensively identify lipids associated functional genes that are development germination processes a large-seed variety. A total 332 were identified; triacylglycerols (TAGs) diacylglycerols abundant during maturation,...
Seed expansion in peanut is a complex biological process involving many gene regulatory pathways. MicroRNAs (miRNAs) play important roles plant growth and development, but little known about their functions during seed expansion, or how they contribute to different lines. We examined miRNA expression patterns at 15 35 days after flowering (DAF) two eighth-generation recombinant inbred lines (RIL8); 8106, medium-pod variety, 8107, super-pod variety. Using high-throughput sequencing, we...
Seed size/weight, a key domestication trait, is also an important selection target during peanut breeding. However, the mechanisms that regulate seed development are unknown. We re-sequenced 12 RNA samples from developing seeds of two cultivated accessions (Lines 8106 and 8107) wild Arachis monticola at 15, 30, 45, 60 days past flowering (DPF). Transcriptome analyses showed ∼36,000 gene loci were expressed in each samples, with nearly half exhibiting moderate (2 ≤ FPKM < 10)...
