Carotenoids are crucial for plant growth and human health. The finding of ORANGE (OR) protein as a pivotal regulator of carotenogenesis offers a unique opportunity to comprehensively understand the regulatory mechanisms of carotenoid accumulation and develop crops with enhanced nutritional quality. Here, we demonstrated that alteration of a single amino acid in a wild-type OR greatly enhanced i...

Despite ongoing research on carotenoid biosynthesis in model organisms, there is a paucity of information on pathway regulation operating in the grasses (Poaceae), which include plants of world-wide agronomic importance. As a result, efforts to either breed for or metabolically engineer improvements in carotenoid content or composition in cereal crops have led to unexpected results. In comparis...

Abstract Plant pathogenic strains of Pseudomonas syringae ( Psy ) spp. have been detected in nonagricultural habitats, including those associated with the water cycle. Their presence aquatic systems allows dissemination over long distances, especially irrigation practices. In May 2021, we sampled 15 sites along Danube River Basin Serbia to gain insight into P. abundance and diversity. We identi...

McNulty, Harkness, Ben-Porath and Williams recently developed Personality Psychopathology Five (PSY-5) scales for the Minnesota Multiphasic Personality Inventory-A (MMPI-A). This study examined these new scales in a sample of 545 adolescents receiving inpatient psychiatric treatment. Item-level principal components analyses were employed to determine the internal structure of each PSY-5 scale a...

Residents enrolled in internal medicine/psychiatry (IM/PSY) and family practice/psychiatry (FP/PSY) programs were surveyed to assess their views concerning training experiences and future plans. The FREIDA online directory was used to supplement missing information. Responses were received from 60% of residents (N=111), representing all active IM/PSY (n=20) and FP/PSY (n=9) programs. Variabilit...

β-Carotene adds nutritious value and determines the color of many fruits, including melon (Cucumis melo). In melon mesocarp, β-carotene accumulation is governed by the Orange gene (CmOr) golden single-nucleotide polymorphism (SNP) through a yet to be discovered mechanism. In Arabidopsis (Arabidopsis thaliana), OR increases carotenoid levels by posttranscriptionally regulating phytoene synthase ...

introduction: g-proteins have an important role in the cell signaling of numerous receptors. the situation of g-proteins in health and disease and their critical role in the development of diabetic side effects is an interested scientific field. here, the changes in the expression of g-protein subunits (gαi, gαs and gβ) were evaluated in hyperglycemic situation of pc12 cells as a cellular model...

background: to evaluate vdr gene variation and its interaction with immune regulatory molecules in osteoporosis. methods: totally 205 pre and postmenopausal women were recruited in the study. after an overnight fast, peripheral blood was taken and centrifuged to sprat serum for measurement of serum parathyroid hormone, 25 hydroxyvitamin d, osteocal­cin and cross laps. the fok i polymorphism in ...

asthma is a chronic inflammatory disorder of the airways. the stress is a factor for asthma which indicates a disorder in the function of communicational mediators of nervous and  immunological systems  such  as  neurotransmitters.  a  study  indicated  that  blood serotonin concentration increases in asthmatic patients. other study indicates that one kind of the serotonin  receptors, named 5ht...
