Seed traits like dormancy, germination rate, and longevity determine the start of the life cycle of plants. The desired values for these traits can be very different for plants growing under natural or agricultural conditions. For the first, germination should be postponed until the start of a favorable growth season and germination should be well balanced with the prevailing environmental conditions. For crop plants, germination should be immediate, uniform and fast. This article is protected by copyright.

Radix Tetrastigma extract (RTE) from different origins were collected and analyzed for their anti-inflammatory effects. Different RTEs showed different abilities to suppress shape deformation, decrease the nitric oxide (NO) production, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression in RAW 264.7 cells. Subsequently, their bioactive components were compared, and results showed RTEs are rich in flavonoid (85.25-436.70 mg RE/g DW), polysaccharides (100.45-349.26 mg glucose/g DW), phenolic (12.92-225.40 mg GAE/g DW) and protein contents (4.429-7.719 mg/g DW). Principal component analysis (PCA) and correlation studies indicated that anti-inflammatory capacity could be more associated with total flavonoid contents. High-performance liquid chromatography (HPLC) and Ultraperformance liquid chromatography-time-of flight mass spectrometry (UPLC-TOF/MS) analysis were conducted, and results showed that rutin, isoquercitrin, kaempferol-3-O-rutinoside and astragalin were main flavonoid compounds, among them astragalin exhibited a prior protective effect, suggesting it might be responsible for RTE's excellent anti-inflammatory capacity. © 2020 Institute of Food Technologists®.The human gut microbiome has been classified into three distinct enterotypes (Bacteroides, Prevotella, and Ruminococcus). The relationship between probiotics and gut enterotype is not yet clear. Cayenne pepper is effective in vitro as a prebiotic for Bifidobacteria and Lactobacilli, so cayenne ingestion with probiotics may lead to more profound gut microbial shifts. We aimed to determine whether probiotics (with or without cayenne pepper) alter gut bacterial community composition and if these changes are associated with the original gut enterotype of the individual. A total of 27 adult participants provided three fecal samples prior to probiotic treatment (baseline), post probiotic treatment (probiotic), and post probiotic plus cayenne pepper treatment (probiotic + cayenne). DNA was extracted, amplified, and the V4 region sequenced on the Illumina MiSeq platform using V2 chemistry. Sequence reads were processed in mothur and assigned using the SILVA reference by phylotype. Three enterotypes characterized the or their needs. © 2020 Institute of Food Technologists®.1.Populations often exhibit genetic diversity in traits involved in responses to abiotic stressors, but what maintains this diversity is unclear. Arabidopsis thaliana exhibits high within-population variation in drought response. One hypothesis is that competition, varying at small scales, promotes diversity in resource use strategies. However, little is known about natural variation in competition effects on Arabidopsis physiology. 2.We imposed drought and competition treatments on diverse genotypes. We measured resource economics traits, physiology, and fitness to characterize plasticity and selection in response to treatments. 3.Plastic responses to competition differed depending on moisture availability. We observed genotype-drought-competition interactions for relative fitness competition had little effect on relative fitness under well-watered conditions, while under drought competition caused rank changes in fitness. selleck products Early flowering was always selected. Higher δ13 C was selected only in the harshest treatment (drought and competition). Competitive context significantly changed the direction of selection on aboveground biomass and inflorescence height in well-watered environments. 4.Our results highlight how local biotic conditions modify abiotic selection, in some cases promoting diversity in abiotic stress response. The ability of populations to adapt to environmental change may thus depend on small-scale biotic heterogeneity. This article is protected by copyright.

This study investigates the clinical and pathologic features of patients with stage I EFHWTs to better evaluate the potential for a reduction of chemotherapy and its associated toxicity. METHODS All patients registered in the Children's Oncology Group (COG) AREN03B2 study between 2006 and 2017 with stage I EFHWTs were identified. EFHWTs were defined as tumors with at least 66% epithelial differentiation, regardless of the degree of differentiation. Clinical information was abstracted from COG records. Event-free survival (EFS) and overall survival (OS) were calculated and compared between groups based on age and therapy. RESULTS The 4-year EFS rate was 96.2% (95% confidence interval, 92%-100%), and the OS rate was 100%; EFS and OS did not statistically significantly differ with the age at diagnosis (95% EFS and OS. These data support the utility of investigating the treatment of stage I EFHWTs with observation alone after nephrectomy. © 2020 American Cancer Society.Olive pomace is considered a solid by-product and a rich source of valuable compounds such as polyphenols, flavonoids with antioxidant properties, and proteins. Nonthermal technologies, which cause alterations to cell permeability, are being explored to assist conventional recovery techniques. The aim of this study was to assess the effect of pulsed electric fields (PEF) and high pressure (HP) on improved recovery yield of the high-added-value compounds or to shorten the extraction time of these compounds. Olive pomace (Tsounati cv) was pretreated with PEF (1.0 to 6.5 kV/cm, 0.9 to 51.1 kJ/kg, and 15 µs pulse width) or HP (200 to 600 MPa and 0 to 40 min). Evaluation of the intracellular compounds extracted via solid-liquid extraction (50% ethanol-water solution) was performed. More intense PEF and HP conditions resulted in a significant increase of the phenolic concentration up to 91.6% and 71.8%, respectively. The increased antioxidant capacity of each extract was correlated to phenolic compound concentration.
