High protein microparticles produced by ionic gelation containing Lactobacillus acidophilus for feeding pacu larvae

Microparticles with high protein content can be used as diets to mimic the proximate composition of Artemia nauplii. After production, the particles were characterized with respect to their proximate composition, mean size, morphology, and rehydration behavior after drying. The protein content, lipid content and the particle moisture were similar to Artemia nauplii, with mean values of 50, 23, and 85%, respectively. Additionally, the particles were used in a pacu (Piaractus mesopotamicus) larval growth experiment. Also, the probiotic Lactobacillus acidophilus was added to one of the diets, and the effects of the diets were evaluated on larvae growth and stress resistance. Larvae fed the experimental diets had lower growth than larvae fed with Artemia nauplii or a commercial diet. All of the evaluated diets, including the experimental ones, showed high ingestion rates (>90%). In the stress test by air exposure, larvae fed with the microparticle without probiotic exhibited a significantly higher mortality than those fed the commercial diet or those fed with Artemia nauplii. The low growth rates may have been due to a potential nutritional inadequacy with respect to the low mineral/vitamin content of the experimental diets. (C) 2014 Elsevier Ltd. All rights reserved.

Photomorphogenic modulation of water stress in tomato (Solanum lycopersicum L.): the role of phytochromes A, B1, and B2

Phytochromes are red/far-red light photoreceptors that mediate a variety of photomorphogenic processes in plants, from germination to flowering. In addition, there is evidence that phytochromes are also part of the stress signalling response, especially in response to water deficit stress, which is the major abiotic factor limiting plant growth and crop productivity worldwide. In this study, we used the phyA (far red-insensitive; fri), phyB1 (temporary red-insensitive; tri) and phyB2 mutants of tomato (Solanum lycopersicum L.) to study the roles of these three phytochromes in drought stress responses. Compared to wild type (WT) plants grown under water-deficit stress conditions, the fri, tri, and phyB2 mutants did not exhibit altered dry weights, leaf areas, stomatal densities, or stomatal opening. The stomatal conductance of all three mutants was severely reduced under both fully-hydrated and water-deficit conditions. Although relative water contents did change after drought stress in each mutant, the most significant reduction in water potential during water stress was observed in the fri mutant. However, this mutant returned its water status to WT levels during rehydration. Although the phyB2 mutant lost more water from detached leaves during abscisic acid (ABA) treatment, phyB2 behaved like WT plants, indicating that this mutant was not insensitive to ABA. Overall, these results indicate that the phytochromes phyA, phyB1, and phyB2 modulate drought stress responses in tomato.
