Summary: This study demonstrates a successful elicitation strategy to increase the production of arachidin-1 and arachidin-3 in peanut hairy root cultures. Combination of cyclodextrin with hydrogen peroxide selectively enhances arachidin-1 yield, while combination of cyclodextrin with methyl jasmonate selectively enhances arachidin-3 yield. Re-elicitation of the cultures further increases the levels of these compounds. Finally, column chromatography and semi-preparative HPLC are used to purify arachidin-1 and arachidin-3 with high purity.

Summary: The study found that the total phenolic content, total flavonoid content, and antioxidant capacity of peanuts decreased and then increased during germination, while the monomeric anthocyanin content first increased and then decreased. The germinated peanuts had lower TFC, DPPH, and FRAP values compared to non-germinated peanuts, but the total phenolic acids and trans-resveratrol content increased during germination.

Summary: Fungi such as Aspergillus flavus and Aspergillus parasiticus infecting food and animal feed are responsible for aflatoxin contamination, posing a significant threat to human and animal health. The study investigated the use of different lighting sources and backgrounds to detect and segregate peanut seeds infected with an aflatoxin producing fungus. Results showed that LED light and a white background with artificial neural network (ANN) achieved 99.7% accuracy in detecting fungal growth on peanuts 72 hours after infection with Aspergillus, while UV light and black background with adaptive neuro-fuzzy inference system (ANFIS) achieved 99.9% accuracy 48 hours after infection.

Summary: The study found that peanut absorbs calcium throughout the entire growing season, and seed calcium concentration can be used as an indicator of early-season seed quality. Split applications of gypsum at early/mid-bloom showed better performance compared to single applications at planting or early bloom and split applications at planting/early bloom.

Summary: The study investigated the effect of the AhRS3 transgene on the expression of endogenous piceid biosynthesis genes in resveratrol-producing rice inbred lines. Results showed significant differences in resveratrol and piceid accumulation in seeds among different lines, as well as distinct expression patterns of UGT genes during seed development. These findings suggest that AhRS3 alters the expression pattern of UGT genes and key resveratrol biosynthesis genes in developing rice seeds.

Summary: This study evaluated the effectiveness of different calcium sources on peanut production by conducting field experiments in the southeastern United States. Results indicated that mined gypsum may be the most effective calcium source, and liquid calcium sources were less effective compared to solid ones. The study provides valuable information for calcium nutrient management in peanut cultivation.

Summary: Production of phosphorus efficient genotypes in groundnut can have positive impacts on the environment and reduce pollution. Identifying efficient P-responding genotypes is crucial for sustaining in P-deficient soils. Pot and lysimeter experiments revealed genotypes that performed best under both P-sufficient and deficient conditions for various traits. Based on P-efficiency indices and surrogate traits of P-uptake, genotypes efficient in response to P were determined.

Summary: This study investigated the combining ability effects and gene action controlling rust resistance in groundnut genotypes through hybridization. The results indicated significant variations in rust resistance, yield, and related traits among the tested genotypes, with both additive and non-additive gene effects influencing trait inheritance. Genotypes with desirable GCA or SCA effects were selected for further breeding.

Summary: The study utilized peanut skin as a precursor for an adsorbent to remove 2,4-D herbicide in water. Acidic conditions were favorable for adsorption, with a maximum capacity of 246.72 mg g(-1) achieved at 298 K. The adsorbent showed high efficiency in removing herbicides from synthetic wastewater, with a removal efficiency of 72%.

Summary: In this study, the peanut ALDH gene AhALDH2B6 was expressed in soybean using genetic modification, and its function in enhancing cold tolerance was confirmed. Transgenic soybeans showed improved growth and reduced stress-related biochemical indicators. The AhALDH2B6 gene specifically up-regulated genes involved in oxidoreductase-related functions, supporting its role in cold stress alleviation.

Summary: In this study, the co-inoculation of Rhizobium pusense S6R2 and Pantoea dispersa YBB19B in groundnut was found to alleviate salt stress and promote plant growth and yield. These strains exhibited multiple plant growth-promoting traits under salt stress conditions. The highest number of nodules was obtained when Rhizobium pusense S6R2 and Bacillus tequilensis NBB13 were co-inoculated in saline soil.
