    Abstract Plants synthesize various compounds for their growth, metabolism, and stress mitigation, and one such group of compounds is the raffinose family of oligosaccharides (RFOs). RFOs are non-reducing oligosaccharides having galactose residues attached to a sucrose moiety. They act as carbohydrate reserves in plants, assisting in seed germination, desiccation tolerance, and biotic/abiotic stress tolerance. Although legumes are among the richest sources of dietary proteins, the direct consumption of legumes is hindered by an excess of RFOs in the edible parts of the plant, which causes flatulence in humans and monogastric animals. These opposing characteristics make RFOs manipulation a complicated tradeoff. An in-depth knowledge of the chemical composition, distribution pattern, tissue mobilization, and metabolism is required to optimize the levels of RFOs. The most recent developments in our understanding of RFOs distribution, physiological function, genetic regulation of their biosynthesis, transport, and degradation in food crops have been covered in this review. Additionally, we have suggested a few strategies that can sustainably reduce RFOs in order to solve the flatulence issue in animals. The comprehensive information in this review can be a tool for researchers to precisely control the level of RFOs in crops and create low antinutrient, nutritious food with wider consumer acceptability.

    Abstract Iron (Fe) and Zinc (Zn) are vital micronutrients for plants and their deficiency causes severe impairments in physiological and biochemical responses of plants. In response to stress emerging due to their deficiency, plants evolve different strategies to regulate the homeostasis network to ensure optimum Fe and Zn uptake. Fe and Zn biofortification of food crops offer a promising approach to alleviate the malnutrition caused due to their deficiency. However, the complex mechanism underlying the fine-tuned processes of mineral uptake, transport and accumulation in seeds involve a multitude of regulatory insights including alteration in root morphology, nutrient partitioning and subsequent accumulation in seeds mediated by different transporters, chelators, transcription factors and post transcriptional regulation which act in a coordinated manner to elicit responses in plants regulating Fe and Zn acquisition. These insights into the regulatory mechanisms will provide a better understanding for improving the Fe- and Zn- use efficiencies, maximization of Fe and Zn bioavailability in edible parts, the deficiency tolerance attributes and subsequent Fe and Zn- biofortification in plants.

    Abstract Jack (Artocarpus heterophyllus) is a multipurpose fruit-tree species with minimal genomic resources. The study reports developing comprehensive transcriptome data containing 80,411 unigenes with an N50 value of 1265 bp. We predicted 64,215 CDSs from the unigenes and annotated and functionally categorized them into the biological process (23,230), molecular function (27,149), and cellular components (17,284). From 80,411 unigenes, we discovered 16,853 perfect SSRs with 192 distinct repeat motif types reiterating 4 to 22 times. Besides, we identified 2741 TFs from 69 TF families, 53 miRNAs from 19 conserved miRNA families, 25,953 potential lncRNAs, and placed three functional eTMs in different lncRNA-miRNA pairs. The regulatory networks involving genes, TFs, and miRNAs identified several regulatory and regulated nodes providing insight into miRNAs' gene associations and transcription factor-mediated regulation. The comparison of expression patterns of some selected miRNAs vis-à-vis their corresponding target genes showed an inverse relationship indicating the possible miRNA-mediated regulation of the genes.

    Abstract Raffinose family oligosaccharides (RFOs) are known to have important physiological functions in plants. However, the presence of RFOs in legumes causes flatulence, hence are considered antinutrients. To reduce the RFOs content to a desirable limit without compromising normal plant development and functioning, the identification of important regulatory genes associated with the biosynthetic pathway is a prerequisite. In the present study, through comparative RNA sequencing in contrasting genotypes for seed RFOs content at different seed maturity stages, differentially expressed genes (DEGs) associated with the pathway were identified. The DEGs exhibited spatio-temporal expression patterns with high RFOs variety showing early induction of RFOs biosynthetic genes and low RFOs variety showing a late expression at seed maturity. Selective and seed-specific differential expression of raffinose synthase genes (AhRS14 and AhRS6) suggested their regulatory role in RFOs accumulation in peanut seeds, thereby serving as promising targets in low RFOs peanut breeding programs. Despite stachyose being the major seed RFOs fraction, differential expression of raffinose synthase genes indicated the complex metabolic regulation of this pathway. The transcriptomic resource and the genes identified in this study could be studied further to develop low RFOs varieties, thus improving the overall nutritional quality of peanuts.

    Abstract Reactive oxygen species (ROS) play a critical role in developmental and signal transduction processes during seed germination and early seedling establishment stages. Higher concentrations of ROS are known to have detrimental effects when the plant is under salt stress. In the present study, we aimed to test the early (1 h) and late (48 h) response of enzyme-driven ROS detoxification system in six peanut genotypes under salt stress at early seedling stage. Salt stress was imposed with three treatment concentrations of NaCl (50, 100 and 200 mM NaCl), all of which showed a reduction in seed germination and seedling vigour index. The 200 mM NaCl stress showed severe reduction of growth, while 100 mM NaCl stress resulted in rapid increase in O 2·− and H2O2 contents. The O 2·− content increased twofold in sensitive genotypes after 1 h of stress, whereas the tolerant genotypes showed ~ 60% rise. A prompt rise (> 50-fold) in SOD transcript was occurred within 1 h of salt stress in the tolerant genotypes (early response). But induction in SOD activity was observed only after 48 h of salt stress (late response). After 48 h of salt stress, the tolerant genotypes showed greater induction of POD activity, whereas in the sensitive genotypes CAT activity was more pronounced. We found POD and CAT played a greater role in H2O2 detoxification in tolerant and sensitive genotypes, respectively, during longer duration of the stress. This study summarizes the selective induction of different components of antioxidant enzyme system and their role in cellular fine tuning of ROS level in peanut under salt stress during seedling establishment stage.
