Fan Wei,Wu Jinggui 한국미생물학회 2020 The journal of microbiology Vol.58 No.8
We conducted a 2-year field experiment which was comprised of five treatments, namely no straw returning (CK), straw mulching (SM), straw plowed into the soil (SP), and straw returned in granulated form (SG). The aim of this study was to investigate the effects of different straw returning modes on soil bacterial and fungal community structure and their relationships to soil organic carbon (SOC) fractions at three different soil depths (0–20, 20–40, and 40–60 cm) in a dryland under maize cultivation in Northeast (NE) China. SM, SP, and SG treatments significantly increased SOC content. Compared with SM and SP treatments, SG treatment significantly increased the content of SOC and easily oxidizable carbon (EOC) in the topsoil (0–20 cm depth), and increased dissolved organic carbon (DOC) and SOC content of the light fraction (LFOC) in the 20–40 cm layer. Meanwhile, SG treatment exhibited the highest microbial biomass C (MBC) content in all of the three soil depths. SG treatment also enhanced bacterial richness as well as fungal richness and diversity in the upper 40 cm of soil. In addition, SG treatment increased the relative abundance of Proteobacteria in all depths, and had the highest relative abundance of Basidiomycota in the first 20 cm of soil. SP treatment showed the lowest soil organic carbon content in all fractions and soil microbial community composition. SM treatment exhibited similar results to SG treatment in SOC, DOC, and LFOC contents, and bacterial diversity in the topsoil and subsoil. As a whole, treatment SG improved soil quality and maize yield, hence we recommend returning granulated straw as the most effective practice for enhancing labile SOC fractions as well as maintaining soil diversity and microbial richness of arid farmlands in NE China.

Background: To evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) creation for the management of portal hypertension in patients with hepatocellular carcinoma (HCC). Methods: A literature search of the MEDLINE/PubMed and Embase databases was conducted. All articles reporting the outcomes of TIPS creation for variceal bleeding and refractory ascites and hepatic hydrothorax in patients with HCC were included. Exclusion criteria were non-English language, sample size < 5, data not extractable, and data reported in another article. Results: A total of 280 patients (mean age, 48–58; male gender, 66%) from five articles were included. TIPS creation was performed for variceal bleeding in 79% and refractory ascites and/or hepatic hydrothorax in 26% of patients. Technical and clinical success was achieved in 99% and 64% of patients, respectively. Clinical failure occurred in 36% of patients due to rebleeding or recurrent bleeding (n = 77) or no resolution or improvement of refractory ascites and hepatic hydrothorax (n = 24). One percent of patient had major complications, including accelerated liver failure (n = 1) and multi-organ failure resulting from hemorrhagic shock (n = 1), all of which resulted in early (i.e., within 30 days) death. Hepatic encephalopathy occurred in 40% of patients after TIPS creation. Lung metastasis was found 1% of patient 5 months (n = 1) and 72 months (n = 1) after TIPS creation. Conclusion: TIPS creation seems to be safe and effective for the management of portal hypertension in patients with HCC.

The study aimed to establish an efficient tool for cultivar identification and characterization being the first steps of apple introduction and improvement program. We utilized a method to efficiently record DNA molecular fingerprints of plant individuals genotyped by RAPD, which could be used as efficient reference information for quick plant identification. Ten of sixty 11-mer primers were screened to identify the 68 apple genotypes which could be distinguished by a combination of several primers. All cultivars were easily identified by the corresponding primers marked on the cultivar identification diagram (CID). The results indicated that the CID strategy developed and employed in the apple cultivar identification could be vital in the utilization of DNA marker in other plants as well as the development of the apple industry.

The distal end of grape berries preferentially cracks during the soaking process in vitro, which may be related to preferentialwater uptake and cell anatomy. Thus, the relationship between water uptake and cell anatomical structure was assessed using49 grape varieties. In vitro immersion experiments were performed on mature berries to measure the diff erences in berrycrackingproperties. A whole-berry in vitro staining method was used to trace the water uptake of the vascular bundles, andparaffi n sections were used to observe and analyze the structural parameters of the diff erent tissues. The results showed thatthe berry-cracking rate and water uptake of the distal end of berries prone to cracking were signifi cantly higher than that ofthe resistant berries. Compared with the berries that were resistant to cracking, the berries that were prone to cracking possesseda thin cuticle, epidermis and sub-epidermis. Dye accumulated in the distal end of the cracking-prone berries, whicheven exhibited cracking during the dyeing process. However, less dye accumulated on the surface of the cracking-resistantvarieties and was only sporadically distributed on the surface. In addition, cracking of the distal end of the berry may alsobe related to other shape and size parameters of the cells in cell layer. Analysis of vascular bundle water transport and thediff erences in the cell structure characteristics of the diff erent varieties, off ered a preliminary explanation for why the distalend of the berry is prone to cracking, providing theoretical support for further research on the mechanisms of berry cracking.

Small interfering RNAs (siRNAs) are effectors of regulatory pathways underlying plant development, metabolism, and stress- and nutrient-signaling regulatory networks. The endogenous siRNAs are generally not conserved between plants; consequently, it is necessary and important to identify and characterize siRNAs from various plants. To address the nature and functions of siRNAs, and understand the biological roles of the huge siRNA population in grapevine (Vitis vinifera L.). The high-throughput sequencing technology was used to identify a large set of putative endogenous siRNAs from six grapevine tissues/organs. Subsequently, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was performed to classify the target genes of siRNA. In total, 520,519 candidate siRNAs were identified and their expression profiles exhibited typical temporal characters during grapevine development. In addition, we identified two grapevine trans-acting siRNA (TAS) gene homologs (VvTAS3 and VvTAS4) and the derived trans-acting siRNAs (tasiRNAs) that could target grapevine auxin response factor (ARF) and myeloblastosis (MYB) genes. Furthermore, the GO and KEGG analysis of target genes showed that most of them covered a broad range of functional categories, especially involving in disease-resistance process. The large-scale and completely genome-wide level identification and characterization of grapevine endogenous siRNAs from the diverse tissues by high throughput technology revealed the nature and functions of siRNAs in grapevine.

Nonlinear Increase of Spatial Noise for Ultrashort Pulses with Different Temporal Widths
Lifu Zhang,Xiquan Fu,Jianqin Deng,Hua Yang,Youwen Wang,Shuangchun Wen,Huiwen Xu,Jinggui Zhang,Jin Zhang,Dianyuan Fan 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.55 No.2
In this paper, the dynamic evolution of the spatial noise modulation of ultrashort laser pulses in carbon disulfide (CS2) is investigated experimentally, and different temporal widths of the stretched pulse are analyzed for spatial noise gain. The spatial noise evolution (i.e., small-scale self-focusing) of ultrashort laser pulses with different temporal widths as a function of the length of the CS2 has been observed. If the spectral bandwidth is invariant, the experimental results show that a stretched pulse with a broader temporal width can postpone the small-scale self-focusing of spatial noise for longer medium length with constant input power or for greater input power with the same medium length.
