- Building hovenia dulcis pseudofruit quality from proteomic and metabolomic perspectivesPublication . Machado, Gilson Gustavo Lucinda; Eller, Elda; Ribeiro, Carlos Henrique Milagres; Costa, Carlos Alexandre Rocha da; Nascimento, Sidney Vasconcelos do; Nahon, Sayure Mariana Raad; Cavalcante, Alice de Paula de Sousa; Costa, Isa Rebecca Chagas da; Valadares, Rafael Borges da Silva; Carvalho, Elisângela Elena Nunes; Boas, Eduardo Valério de Barros VilasHovenia dulcis Thunb. (Japanese grape tree) pseudofruit exhibits a period of growth of 180 days, with maturation initiated between 120 and 150 days after anthesis (DAA). Effective ripening occurs 150 DAA, characterized by intense softening, pectic solubilization and starch-sugar conversion. Multi-omic analysis identified 496 proteins, with 222 being differentially expressed. Significant highlights included energy metabolism (Malate Dehydrogenases, Glyceraldehyde-3-phosphate Dehydrogenase, Pyruvate Kinase) and photosynthetic pathways (Ribulose-1,5-bisphosphate Carboxylase/Oxygenase, Photosystems I and II), indicating that ripening demands a high energy supply. Multivariate analysis stratified the development into three phases: chemical defense (S1-S2), metabolic transition (S3-S6), and sensory ripening (S7). The Variable Importance in Projection (VIP) score and Principal Component 1 (PC1) loadings confirmed that the transition is governed by changes in volatile compounds (2-heptanol), respiratory physiology, density, and Hue angle, with a central role for malate dehydrogenase. Pearson correlations revealed a coordinated system in which central metabolism (Glyceraldehyde-3- phosphate Dehydrogenase, Triose Phosphate Isomerase) is coupled with ethylene signaling (S-adenosylmethionine Synthetase) and antioxidant defenses (Superoxide Dismutase, Catalase, and Peroxiredoxin 2). It is concluded that H. dulcis development is sustained by a strategic proteometabolic network that redirects the investment from protective biomolecules toward the specialization of sensory attributes, defining the final quality of the pseudofruit.
- Methodology for research and learning about mediterranean pasturesPublication . Ortiz, Ana Cano; Meireles, Catarina I. Rodrigues; Raposo, Mauro; Quinto Canas, Ricardo; Fuentes, José Carlos Piñar; Cano, EusebioIn the field study of Mediterranean grasslands, two types were identified, which from the edaphic point of view are classified as subnitrophilic and nitrophilic. Subnitrophilic grasslands include communities dominated by Taeniatherum caput-medusae and to a lesser extent by species of the genus Medicago sp. The second group of nitrophilic grasslands includes two subgroups: (1) those with a high percentage of Hordeum leporinum, which together with subnitrophilic grasslands have a high value for cattle and horse breeding, and as carbon sinks due to the high absorption of CO2. To subgroup (2) belong the grasslands of the Spanish dehesas and Portuguese montados, very rich in Poa bulbosa, Trifolium subterraneum, Biserrula pelecinus, considered of interest by the habitats directive and national and regional governments. Grasslands belonging to the Poetea bulbosae class are of interest for sheep farming, but not as CO2 sinks because they have a lower biomass than the subnitrophilous and nitrophilous of the Sellarietea mediae class. Considering the jaw system of the three types of livestock and the structure of the different pastures, a close correlation should be established between the type of livestock and the type of pasture. All these aspects should be known by future managers, which will enable them to defend the conservation and use of Mediterranean pastures, hence the need to teach them in Universities and Research Centers.
- Physiology of spore formation for Bacillus probiotic productionPublication . Pawar, Lokesh; Singh, Arya; Chouhan, Nayan; Amer, Hadeer A.; Likitha, K.; Prasanthmadduluri, Naga; Singh, Soibam Khogen; Soltani, MehdiProbiotic Immune response Bacillus sp Physiology of Bacillus Bacillus species are highly regarded as probiotics in aquaculture due to their positive impact on host health and disease prevention. This chapter provides a comprehensive overview of the physiological aspects and optimization strategies involved in the production of Bacillus spp. probiotics for aquaculture that contributes to the development of efficient and sustainable aquaculture practices. It highlights the significance of Bacillus spp. as probiotic, their potential in enhancing aquaculture productivity, and the importance of understanding the physiological characteristics of Bacillus spp. to optimize their growth and spore production. The chapter discusses several key factors that influence Bacillus spp. spore production and growth. It explores the effects of carbon sources, lignocellulosic growth substrates, nitrogen sources, medium pH, agitation and aeration, and microelements on the physiology and productivity of Bacillus species. Additionally, the chapter emphasizes the importance of selecting the appropriate cultivation method for scaled-up Bacillus spp. probiotic production in aquaculture. Different cultivation methods, such as batch, continuous, and fed-batch cultures, are evaluated, taking into account their impact on growth, spore formation, and overall probiotic yield. It enables the cultivation of high-quality probiotics with enhanced benefits, including disease prevention, improved nutrient utilization, and growth promotion, thereby enhancing the health and productivity of aquaculture organisms.
