In this study, “Honghu White Lotus”, “Red Lotus (HH)”, “Hunan Cunshan Lotus (CS)”, “Wuyi Xuanlian”, “Space Lotus 36”, “Fujian Jianning White Lotus (JB)”, “Jiangsu Yangzhou Lotus (JY)”, and “Suzhou Dongshan Lotus” were selected as experimental subjects. The lotus seed flesh and lotus plumule of each cultivar were selected for nutritional quality and functional active substance analyses. Comparing different cultivars of lotus seeds, the protein and crude fat contents of JY flesh were the highest at 65.59 mg/g and 13%, respectively. The VC content of JB flesh and lotus plumule is the highest at 4

Abstract:

Since 2017, higenamine has been added to the World Anti-Doping Agency (WADA) prohibited list as a β2-agonist prohibited at all times for sportspersons. According to WADA’s report, positive cases of higenamine misuse have been increasing yearly. However, higenamine occurs naturally in the Chinese herb lotus plumule—the green embryo of lotus (Nelumbo nucifera Gaertn) seeds—commercially available as concentrated powder on the Asian market. This study evaluated the major phytochemical components of lotus plumule products using an appropriate extraction method, followed by a human study in which th

(1) Background: Lotus (Nelumbo nucifera Gaertn.) is an aquatic plant with a long history and ornamental, edible, medicinal, and commercial value. All parts of the lotus are important “homologous and different effects” medicinal herbs as distinct parts of the same plant with different medicinal effects. (2) Methods: Six representative medicinal parts of lotus were selected, i.e., the lotus flower (Nelumbinis Flos, Flo), lotus petiole (Nelumbinis Petiolus, Pet), lotus seedpod (Nelumbinis Receptaculum, Rec), lotus stamen (Nelumbinis Stamen, Sta), lotus seed (Nelumbinis Semen, Sem), and lotus plum

Lotus plumule is a traditional Chinese food that can be used as a beverage. In this study, three kinds of Lotus plumules from different regions of China were selected to observe the preventive effects of extracted alkaloids on CCl4-induced liver injuries.

Abstract:

By comparison of peony and lotus embryos in <em>in vitro</em> culture we established differences in their morphogenetic potential. We traced in peony embryo culture: embryogenesis, embryoidogenesis, organogenesis and histogenesis, whereas the lotus embryo enhibited only one pathway of development - embryogenesis. At the critical stage the embryo becomes independent of the maternal organism, i.e, self-sufficient. Self-sufficiency of the lotus embryo on the 4O-11th day after pollination correlates with development and greening of the first -lead in the plumule, with a sharp increase

Abstract:

Lotus (Nelumbo nucifera) seeds are widely consumed as functional food or herbal medicine, of which cotyledon (CL) is the main edible part, and lotus plumule (LP) is commonly utilized in traditional Chinese medicine. However, few studies have been conducted to investigate the chemical components of CL and LP in dry lotus seeds, not to mention the comparison between wild and domesticated varieties. In this study, a widely targeted metabolomics approach based on Ultra Performance Liquid Chromatography-electrospray ionization-Tandem mass spectrometry (UPLC-ESI-MS/MS) was utilized to analyze the me

Balancing selection is a major mechanism to maintain colour polymorphisms over evolutionary time. In common buzzards, variation in plumage colour was reportedly maintained by a heterozygote advantage: heterozygote intermediates had higher fitness than homozygote light and dark morphs.

The color of plumage in birds is an important feature, often determining descent to a particular species or breed. It serves as a key factor in the interaction of birds with each other due to their well-developed visual perception of the surrounding world. In poultry including chickens, the color of the plumage can be treated as a genetic marker, useful for identifying breeds, populations and breeding groups with their specific traits. The origin of diverse color plumage is the result of two interrelated physical processes, chemical and optical, due to which pigment and structural colors in th

Plumage color is an artificially and naturally selected trait in domestic ducks. Black, white, and spotty are the main feather colors in domestic ducks. Previous studies have shown that black plumage color is caused by MC1R, and white plumage color is caused by MITF. We performed a genome-wide association study (GWAS) to identify candidate genes associated with white, black, and spotty plumage in ducks. Two non-synonymous SNPs in MC1R (c.52G>A and c.376G>A) were significantly related to duck black plumage, and three SNPs in MITF (chr13:15411658A>G, chr13:15412570T>C and chr13:15412

Abstract:

The aim of the present study was to investigate the effect of a single nucleotide polymorphism (SNP) of the endothelin receptor B subtype 2 (EDNRB2) gene on plumage coloration in mule ducks. Test mating (white Tsaiya × white Muscovy ducks) in combination with polymerase chain reaction restriction fragment length polymorphism (PCR RFLP) was performed to investigate the effect of non synonymous SNPs in two maternal lines (a conservation and a selection population) on plumage coloration in mule ducks. One non synonymous SNP (c.995G>A) was identified in white Muscovy ducks and white Tsaiya duck

Abstract:

Carotenoid pigments produce most red, orange and yellow colours in vertebrates. This coloration can serve as an honest signal of quality that mediates social and mating interactions, but our understanding of the underlying mechanisms that control carotenoid signal production, including how different physiological pathways interact to shape and maintain these signals, remains incomplete. We investigated the role of testosterone in mediating gene expression associated with a red plumage sexual signal in red-backed fairywrens ( Malurus melanocephalus ). In this species, males within a single popu

Abstract:

Top-down estimates of surface NOX emissions were derived for 23 European cities based on the downwind plume decay of tropospheric nitrogen dioxide (NO2) columns from the LOTOS-EUROS (Long Term Ozone Simulation-European Ozone Simulation) chemistry transport model (CTM) and from Ozone Monitoring Instrument (OMI) satellite retrievals, averaged for the summertime period (April–September) during 2013. Here we show that the top-down NOX emissions derived from LOTOS-EUROS for European urban areas agree well with the bottom-up NOX emissions from the MACC-III inventory data (R2 = 0.88) driving the CTM

Abstract:

The work was carried out at LLC “Genofond” of the Moscow region on gray-speckled, Zagorsk white-breasted, blue and cream guinea fowls of the VNITIP selection. The bird taken for the experiment was bred in “itself” for a long time and did not give splitting in plumage color. The aim of the work was to find methods for separating guinea fowls by sex at an early age, based on the use of marker genes and their modifiers. It has been established that gray-speckled, blue and Zagorsk white-breasted guinea fowls belong to the eumelanin phenotype in terms of plumage color. The deposition of eumelanin p

Abstract:

Metal vapor plume which induced during high power disc laser welding contains lots of information that related to the welding quality. Stainless steel 304 was taken as the experiment object for the high power disc laser welding experiment. A high-speed camera was used to capture the ultraviolet band and visible light band metal vapor plume images in the laser welding process. Image processing techniques such as median filtering, Wiener filtering, gray level threshold and image binarization were applied to get the images that only metal vapor plume was included. The ratio of the absolute value

Based on field reconnaissance in 2000 and 2001 throughout Yukon but particularly in the areas of the Upper Bonnet Plume River, Wind River, Eagle Plains and Vuntut National Park, information is provided on geographically significant plant occurrences. Three native taxa, Draba kananaskis, Hieracium albiflorum and Prunella vulgaris ssp. lanceolata and five introduced taxa, Alopecurus geniculatus, Dactylis glomerata, Elymus junceus, Lotus corniculatus, and Verbena hastata are reported new to the known flora of the Yukon Territory.

Abstract:

The response of germination and early seedling growth to levels of salinity (0, 50, 100, 150, 200 and 250 mM NaCl) were examined in single seed lots of ten modern rice genotypes. Unaged and deteriorated rice seeds were germinated in rolled paper towels and in Petri dishes. Initial seed quality, final germination, germination rate and early seedling growth were assessed. The samples of the rice genotypes differed in their initial seed quality (measured in terms of Ki). The effect of deterioration varied depending upon the initial seed quality and the severity of the treatment imposed. Ageing (u
