Article Abstract
Important marine microorganisms are resources of renewable energy that may face global population growth and needs. The application of biomass metabolites, such as carotenoids and their derivatives, may solve some agro-food health problems. Herein, a new halophilic producing carotenoid was screened from a Tunisian solar Saltworks (Sfax). The identification of the carotenoid pigments was carried out using HPLC-MS/MS. The predominant pigments produced by this were bacterioruberin and its derivatives and the carotenoids production was found to be of 21.51 mg/mL. Moreover, the data revealed that the carotenoids extract exhibited a high antioxidant activity across four oxidizing assays. The present results suggested that carotenoids extracted from halophilic are interesting sources of natural antioxidants for future innovative applications in agro-food, cosmetic and health fields.
Arbuscular mycorrhiza (AM) represents a symbiotic mutualistic association between most land plants and fungi. AM fungi develops specialized intraradical and highly branched structures, called arbuscules, where bidirectional exchange of nutrients between plant and fungi partners occurs, improving plant growth and fitness. Transcriptional reprogramming and hormonal regulation are necessary for the formation of the arbuscules.
Sarcopenia, characterized by an age-related progressive loss of muscle mass and strength, presents significant health concerns. Recommending dietary nutrition emerges as a viable strategy to counteract muscle deterioration. Vitamin A, indispensable throughout the human life cycle and unattainable through endogenous synthesis, necessitates intake via diet.

Background: Saffron (Crocus sativus L.) is a perennial, bulbous flower whose stigma is one of the most valuable spices, herbal medicines, and dyes. Light is an essential environmental regulator of plant growth, development, and metabolism.
Objective: Retinopathy of prematurity (ROP) is a leading cause of preventable childhood blindness in preterm infants with low birth weight. The efficacy and safety of prophylactic agents, including vitamin A, propranolol and lipids, in reducing ROP incidence remain unclear. This systematic review and meta-analysis evaluated the effectiveness and safety of these agents in preventing ROP.
We speak with Chunzhao Zhao about his enthusiasm to become a scientist and his scientific interest in understanding plant stress resistance to facilitate crop breeding. He discusses his lab's recent Cell Reports paper on FERONIA-mediated phosphorylation cascade in abscisic acid signaling and seed germination.
