“…At the start of peanut pod development, the shell wall or pericarp occupies most of the pod’s volume. Later, the expanded seeds gradually increase in the shell with the pod development [ 7 ]. Boote [ 8 ] divided this peanut pod development process into five distinct stages: pods with tiny embryos (R4), seed growth (R5), fully expanded but immature seeds (R6), fully developed and fully mature wet seeds (R7), and mature dry seeds ready for commercial use (R8).…”

Background Peanut (Arachis hypogaea L.) belongs to an exceptional group of legume plants, wherein the flowers are produced aerially, but the pods develop under the ground. In such a unique environment, the pod’s outer shell plays a vital role as a barrier against mechanical damage and soilborne pathogens. Recent studies have reported the uniqueness and importance of gene expression patterns that accompany peanut pods’ biogenesis. These studies focused on biogenesis and pod development during the early stages, but the late developmental stages and disease resistance aspects still have gaps. To extend this information, we analyzed the transcriptome generated from four pod developmental stages of two genotypes, Hanoch (Virginia-type) and IGC53 (Peruvian-type), which differs significantly in their pod shell characteristics and pathogen resistance. Results The transcriptome study revealed a significant reprogramming of the number and nature of differentially expressed (DE) genes during shell development. Generally, the numbers of DE genes were higher in IGC53 than in Hanoch, and the R5-R6 transition was the most dynamic in terms of transcriptomic changes. Genes related to cell wall biosynthesis, modification and transcription factors (TFs) dominated these changes therefore, we focused on their differential, temporal and spatial expression patterns. Analysis of the cellulose synthase superfamily identified specific Cellulose synthase (CesAs) and Cellulose synthase-like (Csl) genes and their coordinated interplay with other cell wall-related genes during the peanut shell development was demonstrated. TFs were also identified as being involved in the shell development process, and their pattern of expression differed in the two peanut genotypes. The shell component analysis showed that overall crude fiber, cellulose, lignin, hemicelluloses and dry matter increased with shell development, whereas K, N, protein, and ash content decreased. Genotype IGC53 contained a higher level of crude fiber, cellulose, NDF, ADF, K, ash, and dry matter percentage, while Hanoch had higher protein and nitrogen content. Conclusions The comparative transcriptome analysis identified differentially expressed genes, enriched processes, and molecular processes like cell wall biosynthesis/modifications, carbohydrate metabolic process, signaling, transcription factors, transport, stress, and lignin biosynthesis during the peanut shell development between two contrasting genotypes. TFs and other genes like chitinases were also enriched in peanut shells known for pathogen resistance against soilborne major pathogens causing pod wart disease and pod damages. This study will shed new light on the biological processes involved with underground pod development in an important legume crop.

“…Similar results were obtained in the petioles and stems. In the seasonal and diurnal changes, the contents of fructose and glucose in the leaves and petioles were markedly higher than that of sucrose (Zheng et al 2001).…”

“…1, 3, and 4). In the previous paper, it was also reported that the sucrose content in the petioles gradually increased with the growth duration while the fructose and glucose contents decreased (Zheng et al 2001). Yamamoto et al (1970) showed that sucrose was synthesized from f11lctose and glucose in the vascular bundles of tobacco plants.…”

“…1, 3, and 4). Zheng et al (2001) reported that in the fully expanded leaves, expanding leaves, and gynophore sap of peanut plant, the fructose and glucose contents were the highest and the sucrose content was the lowest among the sugars, and that when the peanut plant was transferred from natural conditions to constant darkness, the fructose content in the expanding leaves continued to show a diurnal cycle, while in the fully expanded leaves, the fructose content decreased, suggesting that photoassimilates might be exported from the fully expanded leaves to the expanding leaves in the form of fructose.

“…To obtain neutral sugars, the sugar extract was passed through an ion-exchange column. Crude starch in the ethanol-insoluble fraction was quantified as described in the previous paper (Zheng et al 2001). The contents of neutral sugars were determined by HPLC with an attached RI detector (Model: RI-930, Japan Spectroscopic Co., Ltd., Tokyo).…”

To investigate the translocation form of photo assimilates in the peanut (Arachis hypogaea L.) plant, the plants were individually supplied with 13COZ for 30 min. In the leaves, during the 13CO Z feeding period, fructose was most strongly labeled with 13C, followed by glucose, whereas a small amount of 13C was incorporated into sucrose. Within 1 d after the end of the 13CO Z feeding, the l3C abundances and 13C amounts of fructose and glucose rapidly decreased within 120 min, but increased from 120 to 240 min, and markedly decreased afterwards, while those of sucrose remained constantly low. In the petioles and stems, during the 1:3C labeling period, the 13C abundances and 13C amounts of fructose and glucose were also remarkably higher than those of other sugars and after the end of the 13CO z supply, they remained constantly higher than those of sucrose. In the leaves, a large quantity of 13C was incorporated into starch during the 13C labeling period and within 120 min after the end of the 13CO Z supply, and thereafter, rapidly metabolized. Similar results were observed for the petioles and stems. The above results indicate that the carbon currently fixed in the leaves is rapidly exported from the leaves to the petioles and stems and translocated to other parts of the plant in the forms of fructose and glucose but not sucrose, in contrast to other crops in which sucrose is the major translocation form of photoassimilates.
