Deciphering the mitochondrial genome of Juglans mandshurica (Juglandaceae)

Mitochondrial DNA Part B (2023)

Xun Su Qiong Liu Haili Guo Dechang Hu Dan Liu

Juglans mandshurica Maxim., 1856 is a second-class, protected, rare tree species of high economic and ecological value. We elucidated the complete mitochondrial (mt) genome of J. mandshurica using the Illumina Novaseq 6000 and Nanopore platforms. The complete sequences of 558,032 and 161,386 bp had an overall GC content of 45.0% and 45.3%, respectively, and 61 genes could be annotated, including 38 protein-coding, 20 tRNA, and 3 rRNA genes. The high-quality J. mandshurica mt genomic sequences presented in this study will serve as a useful resource for a range of genetic, functional, evolutionary, and comparative genomic studies on this species of the Juglandaceae family.

Patterns of Diversity and Community Assembly and Their Environmental Explanation across Different Types of Shrublands in the Western Loess Plateau

Forests (2024)

Jinshi Xu Han Dang Dechang Hu Ping Zhang Xiao Liu

Shrubland is an important type of vegetation in the semi-arid region of the western Loess Plateau, and it is of great value to the maintenance of biodiversity and soil and water conservation. Equally, there may be significant differences in the level of diversity and the community assembly patterns across different types of shrublands (desert, alpine, and secondary shrublands). This study aimed to reveal the diversity and the community assembly patterns of different types of shrublands and the environmental explanations for these by using a taxonomic and phylogenetic analysis approach, as well as by considering soil and climate factors. The diversity level of the desert shrublands was low, and the habitats of the three types of shrubland were significantly different. Precipitation may be the main environmental factor driving the variation in and diversity of these types of shrubland. All three types of shrubland were strongly affected by environmental filtering and competitive exclusion, and their community assembly patterns were similar.

Preliminary Research on Radiance Fog Detection based on time series MTSAT data

The international archives of the photogrammetry, remote sensing and spatial information sciences/International archives of the photogrammetry, remote sensing and spatial information sciences (2015)

X. Y. Wen Z. Li Sui Zhang Shirong Shen Dechang Hu

Abstract. Fog is a kind of disastrous weather phenomenon. In this paper, the geostationary satellite MTSAT imagery is selected as the main data source to radiance fog detection. According to the unique feature of radiance fog from its generation to dissipation, especially considering the difference between clouds and fog during their lifecycle, the characteristics in frequency domain was constructed to discriminate fog from clouds, The time series MTSAT images were register with a modified Gauss Newton optimization method firstly, then, the Savitzky-Golay smoothing filter was applied to the time series remote sensing imageries to process the noises in the original signal, after that the non-orthogonal Haar wavelets was applied to convert the signal from time domain into frequency domain. The coefficient of high frequency component, including the properties: “max”, “min”, “the location of the min”, “the interval length between the max and min”, “the coefficient of linear fit for the high frequency”, these properties are selected as the characteristic parameters to distinguish fog from clouds. The experiment shows that using the algorithm proposed in this paper, the radiance fog could be monitored effectively, and it is found that although it is difficult to calculate the thickness of the fog directly, while the duration of fog could be obtained by using the frequency feature.

SRAP analysis on genetic relationships of genotypes in the genusMalusMill.

Biotechnology & Biotechnological Equipment (2014)

XU Rong-xue Dechang Hu Yuyan Chen Ping Zhang Xiaoman Jiang

Thirteen sequence-related amplified polymorphism (SRAP) primers combined with polymerase chain reaction (PCR) were used to evaluate the genetic relationships among 24 genotypes of the genus Malus Mill. including Sect. Malus, Baccatus, Sorbomalus and Chloromeles. Out of 115 surveyed fragments, 107 (93.04%) were polymorphic. Coefficients of genetic similarity ranged from 0.538 to 0.868, with an average value of 0.720 between pairs of materials, which indicated the high degree of polymorphism within this species. Cluster analysis showed that all genotypes were divided into six groups. A dendrogram showed that some of the clustered genotypes were largely congruent for geographical distribution. The species in Sect. Malus, Sorbomalus and Chloromeles were separated to a great extent. However, the DNA patterns for some genotype groups did not demonstrate relative agreement in their pedigrees. In Sect. Sorbomalus, M. yunnanesis was independently separated, while M. prattii were clustered in group III with M. bhutanica, M. platycarpa and M. fusca classified into Ser. Kansuenses. Five species originated from the American region were dispersed into two groups within the dendrogram. The conflicts were reflecting their complex genetic backgrounds.

Bioavailability and pharmacokinetics of florfenicol in broiler chickens

Journal of Veterinary Pharmacology and Therapeutics (2003)

Jianzhong Shen Dechang Hu Xin Wu Joel R. Coats

The bioavailability and pharmacokinetic disposition of florfenicol in broiler chickens were investigated after intravenous (i.v.), intramuscular (i.m.) and oral administrations of 15 and 30 mg/kg body weight (b.w.). Plasma concentrations of florfenicol were determined by a high performance liquid chromatographic method in which plasma samples were spiked with chloramphenicol as internal standard. Plasma concentration–time data after i.v. administration were best described by a two‐compartment open model. The elimination half‐lives were 168 ± 43 and 181 ± 71 min, total body clearance 1.02 ± 0.17 and 1.02 ± 0.16 L·kg/h, the volume of distribution at steady‐state 4.99 ± 1.11 and 3.50 ± 1.01 L/kg after i.v. injections of 15 and 30 mg/kg b.w., respectively. Plasma concentration–time data after i.m. and oral administrations were adequately described by a one‐compartment model. The i.m. bioavailability and the oral bioavailability of florfenicol were 95, 98 and 96, 94%, respectively, indicating that florfenicol was almost absorbed completely after i.m. and oral administrations of 15 and 30 mg/kg b.w.

Potential biological mechanisms underlying the endangered status of Glehnia littoralis revealed by nrDNA ITS and RAPD analyses

Biotechnology & Biotechnological Equipment (2020)

Weiwei Li Bin Li Ping Zhang Dechang Hu Ailan Wang

Certain biological mechanisms of Glehnia littoralis, an endangered medicinal plant in China, may be underlying its endangered status and this has attracted extensive attention from researchers. In this study, nuclear ribosomal DNA internal transcribed spacer (nrDNA ITS) sequences and random amplified polymorphic DNA (RAPD) were investigated to determine the genetic diversity of G. littoralis. A total of 291 samples from 11 G. littoralis populations were collected from the east coast of China. The high genetic diversity and large genetic differentiation within populations were reconfirmed by both ITS (Ht = 0.576, Hs = 0.512, Gst = 0.1526) and RAPD analyses (Ht = 0.51, Hs = 0.35, Gst = 0.31). The phylogenetic trees showed consistent topologies based on ITS and RAPD; all populations were divided into two clades. Mantel tests (ITS: r = 0.3296, p = 0.067; RAPD: r = 0.036, p = 0.418) showed no significant positive correlation between the geographical distance and genetic distance for G. littoralis populations. These results showed that G. littoralis has great evolutionary potential and its status as endangered might be related to special dispersal and germination mechanisms of its seeds, as well as habitat destruction. In conclusion, we suggest that the conservation strategy for G. littoralis should be based on the protection of all the wild populations to the extent possible.
