“…Peanut ( Arachis hypogaea L.) is one of the most important widely grown oil-crops, providing 20% of the global cooking oil and 11% of protein production annually 1 . After flowering and fertilization of peanuts, a novel organ called a peg (which is an elongated ovary) forms 2 .…”

“…In this study, using RNA-seq profiling, the differentially expressed genes of peanut shells and kernels were identified under Ca 2+ sufficient and deficient conditions. This study had three major purposes: (1) to compare the DEGs of shells and seed kernels of peanut plants between free Ca 2+ sufficient and free Ca 2+ deficient treatments; (2) to identify candidate genes involved in peanut embryo and shell development processes and affected by Ca 2+ ;…”

Calcium is not only a nutrient necessary for plant growth but also a ubiquitous central element of different signaling pathways. Ca2+ deficiency in soil may cause embryo abortion, which can eventually lead to abnormal development of peanut pods during the harvest season. To further study the mechanisms by which Ca2+ affects the shells and kernels of peanuts, transcriptome sequencing was used to explore the genes differentially expressed in shells and kernels during the early stage of peanut pod development between Ca2+ sufficient and deficient treatments. In this study, 38,894 expressed genes were detected. RNA-seq based gene expression profiling showed a large number of genes at the transcriptional level that changed significantly in shells and kernels between the Ca2+ sufficient and deficient treatments, respectively. Genes encoding key proteins involved in Ca2+ signal transduction, hormones, development, ion transport, and nutrition absorption changed significantly. Meanwhile, in the early stage of pod development, calcium first promoted nutrient absorption and development of shells, which has less effect on the formation of seed kernels. These results provide useful information for understanding the relationship between Ca2+ absorption and pod development.

“…Peanut ( Arachis hypogaea L.) is an economic crop that contributes 20% to the global oil production and 11% of the protein supply per year (Chen et al, 2014 ). Aerial flowering and underground development of fruit are special genetic characteristics of peanuts, and the ecological environment of dark, moist and mechanical stimulation is essential conditions for pod development.…”

Calcium not only serves as a necessary nutrient for plant growth but also acts as a ubiquitous central hub in a large number of signaling pathways. Free Ca2+ deficiency in the soil may cause early embryo abortion, which eventually led to abnormal development of peanut pod during the harvest season. To understand the mechanisms of Ca2+ regulation in pod development, transcriptome analysis of peanut gynophores and pods was performed by comparing the treatments between free Ca2+ sufficiency and free Ca2+ deficiency using Illumina HiSeq™ 2000. 9,903,082,800 nt bases are generated totally. After assembly, the average length of 102,819 unigenes is 999 nt, N50 is 1,782 nt. RNA-seq based gene expression profilings showed a large number of genes at the transcriptional level changed significantly between the aerial pegs and underground swelling pods under free Ca2+ sufficienct or deficiency treatments, respectively. Genes encoding key members of Ca2+ signaling transduction pathway, enzymes for hormone metabolism, cell division and growth, transcriptional factor as well as embryo development were highlighted. This information provides useful information for our further study. The results of digital gene expression (DGE) indicated that exogenous calcium might contribute to the development of peanut pod through its signal transduction pathway, meanwhile, promote the normal transition of the gynophores to the reproductive development.

Background: Peanut (Arachis hypogaea L.) is an important oil and economic crop. Calcium can regulate plant autoimmunity, respond to biotic and abiotic stresses, and improve plant resistance to pathogens. The enrichment of beneficial microorganisms in the rhizosphere is related to plant disease resistance and soil development. The purpose was to analyze the differences of peanut rhizosphere microbial community structure between calcium treatment and control during two growth stages, and the reason that calcium application could improve peanut’s resistance to soil-borne pathogens.. Results: The 16S amplicon sequencing of rhizosphere microbiome showed that calcium application significantly enriched Serratia marcescens and other three dominant strains at the seedling stage. At the pod filling stage, ten dominant stains such as Sphingomonas changbaiensis and Novosphingobium panipatense were enriched by calcium. Serratia marcescens aseptic fermentation filtrate was mixed with PDA medium and inoculated with soil-borne pathogens, which could inhibit the growth of Fusarium solani and Aspergillus flavus at the seedling stage. The fermentation filtrate of Novosphingobium panipatense was mixed with PDA medium and inoculated with main pathogens, which could inhibit the growth of Sclerotium rolfsii and Leptosphaerulina arachidicola.Conclusions: Calcium application enhanced the ability of peanuts to resist pathogens by enriching specific dominant bacteria.
