We show that NITRATE REGULATORY GENE2 (NRG2), which we identified using forward genetics, mediates nitrate signaling in Arabidopsis thaliana. A mutation NRG2 disrupted the induction of nitrate-responsive genes after treatment by an ammonium-independent mechanism. The content roots was lower mutants than wild type, may have resulted from reduced expression NRT1.1 (also called NPF6.3, encoding a transporter/receptor) and upregulation NRT1.8 NPF7.2, xylem transporter). Genetic molecular data...

The present study investigated the effects of different extraction methods including water-water bath (W-WB), ethanol-water (E-WB), deep eutectic solvent (DES) combined with ultrasound-assisted (DES-UAE), microwave-assisted (DES-MAE), and enzyme-assisted (DES-EAE) on flavonoids (total flavonoid content, composition, stability) in jujube. highest total content 8.03 mg/g was obtained by DES-MAE extraction. Fifteen types were identified from amount rutin produced E-WB DES-UAE 66.88 ± 1.58 μg/g...

Summary Plants have evolved sophisticated mechanisms to adapt fluctuating environmental nitrogen availability. However, more underlying genes regulating the response nitrate yet be characterized. We report here identification of a regulatory mutant whose mutation mapped Cleavage and Polyadenylation Specificity Factor 30 gene ( CPSF 30‐L ). In mutant, induction nitrate‐responsive was inhibited independent ammonium conditions restored by expression wild‐type 65 kDa encoded . Molecular genetic...

Nitrogen is an essential macronutrient for plant growth and development. Nitrate the major form of nitrogen acquired by most crops also serves as a vital signaling molecule. absorbed from soil into root cells usually low-affinity NRT1 NO 3 - transporters high-affinity NRT2 transporters, with NRT2s serving to absorb under – limiting conditions. Seven members have been identified in Arabidopsis , they shown be involved various biological processes. In this review, we summarize spatiotemporal...

Arabidopsis thaliana phosphatidylinositol 3-kinase (AtVPS34) functions in the development and germination of pollen by catalyzing biosynthesis 3-phosphate (PI3P). In yeast, Vps15p is required for membrane targeting activity Vps34. The expression VPS15 (AtVPS15), an ortholog yeast Vps15, mainly detected grains tubes. To determine its role tube growth, we attempted to isolate T-DNA insertion mutants AtVPS15; however, homozygous lines atvps15 were not obtained from progeny atvps15/+...

Pasteurella multocida is an important pathogenic bacterium of domestic animals.Here, we found that Pm0442 was dramatically up-regulated in infected mice among 67 predicted lipoproteins P. serotype A CQ2 strain (PmCQ2), and deletion PmCQ2 significantly decreased bacterial colonization inflammatory responses infectious mice, resulting improved survival. Meanwhile, PmCQ2Δ0442 could provide 70%-80% protection to challenged with 3.08×107 CFU PmCQ2. participated the influences capsular...

Potassium (K) is the essential element for plant growth. It one of critical factors that determine crop yield, quality, and especially leaf development in tobacco. However, molecular mechanism potassium use efficiency (KUE), non-coding RNA, still unknown. In this study, tobacco seedlings were employed, their hydro-cultivation with K treatments low sufficient concentrations was engaged. Physiological analysis showed treatment could promote malondialdehyde (MDA) accumulation antioxidant enzyme...

The expression of animal digestive enzymes reflects important dietary adaptations. pangolin, also known as scaly anteater, is a specialized myrmecophage that consumes mainly ants and termites, but its have not been fully investigated. Therefore, in this study, we used shotgun proteomic analysis to examine the protein components saliva intestinal juice Sunda pangolin (Manis javanica) died shortly after being rescued. contained greater variety enzymes, including α-amylase,...

Cadmium (Cd) is known as one of the most hazardous elements in environment and a persistent soil constraint toxic to all flora fauna. In this study, we conducted physiological, biochemical, transcriptomic analyses Nicotiana rustica (N. rustica) tabacum tabacum) treated with CdCl2 know underlying molecular mechanisms Cd accumulation. As result, N. had more dry weight than tabacum. Additionally, accumulated higher concentration (69.65 times), Cd2+ influx (1.32-fold), glutathione S-transferases...

Consecutive monoculture practice facilitates enrichment of rhizosphere pathogenic microorganisms and eventually leads to the emergence replant disease. However, little is known about interaction relationship among pathogens enriched in soils, Nucleotide binding-leucine-rich repeats (NB-LRR) receptors that specifically recognize effector-triggered immunity (ETI) physiological indicators under disease stress Rehmannia glutinosa. In this study, a controlled experiment was performed using...

Abstract Plant spacing usually refers to distances between plants within and rows in the field. Different of crop planting would generally influence size, plant architecture, economical productivity et al . Present research provided a time course monitoring on tissue transmission tobacco stem development from with different spacing. The result showed cambium activity, vascular bundle thickness, lignin, cellulose, hemicellulose content differed because varied spacing, as well macro nutrients...
