Salinity is a major issue affecting photosynthesis and crop production worldwide. High salinity induces both osmotic and ionic stress in plant tissues as a result of complex interactions among morphological, physiological, and biochemical processes. Salinity, in turn, can provoke inactivation of some enzymes in the Calvin-Benson cycle and therefore affect the fine adjustment of electron transport in photosystem I and carbon related reactions. Here, we used three contrasting Jatropha curcas genotypes namely CNPAE183 (considered tolerant to salinity), CNPAE218 (sensible), and JCAL171 (intermediate) to understand salinity responses. By performing a long-term (12 months) experiment in land conditions, we investigated distinct mechanisms used by J. curcas to cope with threatening salinity effects by analyzing gas exchange, mineral nutrition and metabolic responses. First, our results highlighted the plasticity of stomatal development and density in J. curcas under salt stress. It also demonstrated that the CNPAE183 presented higher salt-tolerance whereas CNPAE218 displayed a more sensitive salt-tolerance response. Our results also revealed that both tolerance and sensitivity to salinity were connected with an extensive metabolite reprogramming in the Calvin-Benson cycle and Tricarboxylic Acid cycle intermediates with significant changes in amino acids and organic acids. Collectively, these results indicate that the CNPAE183 and CNPAE218 genotypes demonstrated certain characteristics of salt-tolerant-like and salt-sensitive-like genotypes, respectively. Overall, our results highlight the significance of metabolites associated with salt responses and further provide a useful selection criterion in during screening for salt tolerance in J. curcas in breeding programmes.

Introduction. Camu-camu is a native Amazonian fruit mainly known for its high vitamin C content. Its composition confers high antioxidant capacity on this fruit and makes it a potential source of antioxidant products. The use of spray-drying with the aid of a carrier agent is a technique that has been applied for the preservation of important components of foods and drugs. The objective of our work was to evaluate the influence of those agents used as shell material on the vitamin content and total phenolic compounds of camu-camu powder juice obtained by spray-drying. Materials and methods. A commercial frozen camu-camu pulp was the raw material; maltodextrin and gum arabic were the selected carrier agents. Processes were performed in a mini-spray-dryer with inlet and outlet air temperatures of 180 °C and 85 °C, respectively, and a drying air flow rate of 700 L·h?1. Laser diffraction was used to determine the particle size distribution of the samples, and sorption isotherms of spray-dried camu-camu were measured using a static gravimetric method. Total phenolic compounds and vitamin C were determined in the raw pulp and in the powders obtained. Results. When using gum arabic and maltodextrin as the carrier agents, the moisture results obtained for the spray-dried camu-camu powders were 2.8% and 3.2%, respectively; the process yield was 84% and 72%, respectively. The spray-dried powder produced using gum arabic presented higher contents of vitamin C [(15,363 ± 226) mg·100 g?1] and phenolic compounds [(6,654 ± 596) mg GAE·100 g?1] than the powder obtained with maltodextrin, respectively (11,258 ± 298) mg·100 g?1 and (5,912 ± 582) mg GAE·100 g?1. Conclusions. The concentration factors for the vitamin C and phenolic compounds in camu-camu powder reveal the effectiveness of spray-drying to preserve the antioxidant capacity of this fruit. Gum arabic was a more effective barrier than maltodextrin for bioactive compound retention. MenosIntroduction. Camu-camu is a native Amazonian fruit mainly known for its high vitamin C content.
