The genus Mentha encompasses mint species cultivated for their essential oils, which are formulated into a vast array of consumer products. Desirable oil characteristics and resistance to the fungal disease Verti- cillium wilt are top priorities for the mint industry. However, cultivated mints have complex polyploid ge- homes and are sterile. Breeding efforts, therefore, require the development of genomic resources for fertile mint species. Here, we present draft de novo genome and plastome assemblies for a wilt-resistant South African accession of Mentha Iongifolia （L.） Huds., a diploid species ancestral to cultivated peppermint and spearmint. The 353 Mb genome contains 35 597 predicted protein-coding genes, including 292 disease resistance gene homologs, and nine genes determining essential oil characteristics. A genetic linkage map ordered 1397 genome scaffolds on 12 pseudochromosomes. More than two million simple sequence repeats were identified, which will facilitate molecular marker development. The M. Iongifolia genome is a valuable resource for both metabolic engineering and molecular breeding. This is exemplified by employing the genome sequence to clone and functionally characterize the promoters in a peppermint cultivar, and demonstrating the utility of a glandular trichome-specific promoter to increase expression of a biosynthetic gene, thereby modulating essential oil composition.

Determination of Vapor Pressure of Liquid copper by carrier Gas Method

引用

Journal of Materials Science & Technology 2013年第12期29卷 1209-1213页

作者： Y.J.Duan B.chen Y.c.Ma M.Gao K.Liu Institute of Metal Research Chinese Academy of Sciences

The relationship between the vapor pressure of liquid copper and the flow rate of carrier gas argon was discussed, when the carrier gas method was used to determine the vapor pressure of liquid copper at 1892 K. The proper argon flow rate range obtained was 150-500 mL/min and enough evidence was provided to verify the vapor pressure-flow rate of carrier gas relationship at the target temperature. Based on the proper flow rate range, the vapor pressure of liquid copper was measured at 1609-1892 K. The relationship of vapor pressure-temperature obtained by the method of regression analysis can be expressed as： In（p/Pa） = （25.470 -I- 0.903） - （39099.8 -4- 1574.5）/T, Further, the thermodynamic properties including the heat of vaporization and the Gibbs free energy of the cu （I） = cu （g） reaction were calculated by the vapor pressiJre obtained over the temperature range covered.

Long range electromagnetic field nature of nerve signal propagation in myelinated axons

chinese Physics B 2022年第3期31卷 619-623页

The nature of saltatory conduction in myelinated axon described by equivalent circuit and circuit theory is still contentious. Recent experimental observations of action potentials transmitting through disjointed nerve fibers strongly suggest an electromagnetic wave propagation mechanism of the nerve signals. In this paper, we employ the electromagnetic wave model of the myelinated axon to describe action potential signal propagation. We use the experimental frequency-dependent conductivity and permittivity values of the nerve tissues in order to reliably calculate the electromagnetic modes by using electromagnetic mode solvers. We find that the electromagnetic waves above 10 kHz can be well confined in extracellular fluid–myelin sheath–intracellular fluid waveguide and propagate a distance of 7 mm without much attenuation. Our study may serve as one of the fundamental researches for the better understanding of the nervous system.

El-Burullus Lake is one of the four Egyptian Ramsar sites that constitute internationally important wetlands as they contain a rich biodiversity and have a large number of water bird *** the valuable resources in El-Burullus Lake and its surrounding area have faced various threats to wetlands over recent *** study was carried out to evaluate the dynamics of land cover change using three change scenes of recent and past satellite data from 1990 to *** study utilized ArcGIS10.7,ERDAS Imagine 14,Landsat TM(1990,1999,and 2010),Landsat OLI-TIRS(2019)to analyze the land-use/land-cover(LULc)of El-Burullus *** Difference Vegetation Index(NDVI)and Normal-ized Difference Water Index(NDWI)were employed to assess the change scenario of the *** indicated that vegetated land has increased significantly with a concomitant shrinkage in the water body and open soil during the study *** 53 km^2(7.0%)of water body and 8.7 km^2(1.3%)of open soil were lost,while vegetation areas expanded to approximately 29.9 km^2(7.4%).Factors that underpin the observed changes in the area are;reclamation projects and fish-farms which are creating the danger of drying up of the southern coastal parts of the lake,as well as spreading of reed beds(mainly:Phragmites australis)that covers about 20%of El-Burullus lake which led to dry up the lake ***,the study suggests the need for urgent attention on conservation of remaining wetland resources for sustainable utilization for the next generation.
