The brain, composed of billions of neurons, is a complex network of interacting dynamical systems controlling all body functions. Neurons are the building blocks of the nervous system and their impairment of their functions could result in neurodegenerative disorders. Accumulating evidence shows an increase of brain-affecting disorders, still today characterized by poor therapeutic options.

Nevertheless, little information is available on the metabolomic profile of this wine. Thus, in this paper we evaluated the colourimetric parameters, H NMR profiles and free amino acids content of 'Asprinio' wines, bottled by two different wineries (hereafter 'Asprinio_A' and 'Asprinio_B') collected in 2019 and 2020, using 'Greco di Tufo' for comparison.

By using two algal based commercial biostimulants in combination with the cv. MicroTom model system, we assessed how the modulation of nitrogen metabolites and potassium levels could contribute to mediate physiological mechanisms that are known to occur in response to salt/and or osmotic stress.

In a previous study on shoot tissues it was shown that this species withstands with high salinity at the seedling stage restricting the sodium entry into shoot and modulating over time the leaf synthesis of organic osmolytes for osmotic adjustment.

In the last decades, it became evident that algal formulations can induce multiple effects on crops (including an increase in biomass, yield, and quality), and that algal extracts contain a series of bioactive compounds and signaling molecules, in addition to mineral and organic nutrients. The need to reduce the non-renewable chemical input in agriculture has recently prompted an increase in the use of algal extracts as a plant biostimulant, also because of their ability to promote plant growth in suboptimal conditions such as saline environments is beneficial.

GB plays an important role in osmoregulation, in fact, it is one of the main nitrogen-containing compatible osmolytes found in Poaceae. It can interplay with molecules and structures, preserving the activity of macromolecules, maintaining the integrity of membranes against stresses and scavenging ROS.

We measured hydrogen peroxide (HO) and malondialdehyde (MDA), which are indicator of oxidative stress. Moreover, we measured the concentration of reduced and oxidized ascorbate and glutathione that are involved in ROS detoxification together with phenolics, anthocyanins and tocopherols.

Production of rich antioxidant fruit could represent a way to delay fruit senescence and preserve its characteristics. We investigated the antioxidant metabolites (ascorbate, glutathione, tocopherols, and polyphenols) and enzymes (ascorbic peroxidases, peroxidases and polyphenol oxidases) involved in the antioxidant response in forty-three accessions of sweet cherry fruits from Campania region.

Moreover, in fields, roots can grow in soils which show spatial variation in water content and salt concentration, also because of the type of irrigation. Salinity impairs crop growth and productivity by inhibiting many physiological and metabolic processes, in particular nitrate uptake, translocation, and assimilation.

Their responses to stresses have been extensively studied to provide new metabolic targets and improving the tolerance to adverse environments. Most of these studies have been performed in growth chambers under low light [300-350 µmol m s photosynthetically active radiation (PAR), LL].

The food industry requires precise traits for morphological, chemical, and physical kernel features so that some cultivars could be more suitable for specific industrial processing. In this study, agronomical and morphological features of 29 hazelnut cultivars were evaluated and a detailed structural characterization of kernel polyphenols was performed, confirming the presence of protocatechuic acid, flavan-3-ols such as catechin, procyanidin B2, six procyanidin oligomers, flavonols, and one dihydrochalcone in all the analyzed cultivars.

Distribution pattern of the retrotransposons of closely related plant species generally reflects a close phylogenetic relationship. In contrast, we found that several retrotransposon sequences from the same genome exhibited a high degree of divergence and had a relatively high degree of identity versus retrotransposon sequences from widely divergent species, including an ancestral phytopathogen fungus.

LTR- retrotransposons possess unique properties that make them appropriate for investigating relationships between populations, varieties and closely related species. Myrtus communis L.
View Article and Find Full Text PDFStress modulation of retrotransposons may play a role in generating host genetic plasticity in response to environmental stress. Transposable elements have been suggested to contribute to the evolution of genes, by providing cis-regulatory elements leading to changes in expression patterns. Indeed, their promoter elements are similar to those of plant defence genes and may bind similar defence-induced transcription factors.
