AbstractChina has made great efforts to alleviate poverty in rural ethnic minority areas and targeted achieving the poverty-alleviation task by the end of 2020. Aba, Ganzi, and Liangshan, three of the poorest ethnic prefectures in Sichuan Province, Southwest China, have all implemented “Internet+” tactics since 2013, which have had the positive effect of increasing family revenues by improving communication infrastructure and encouraging the large-scale use of e-commerce. This paper aims to comprehensively investigate whether “Internet+” tactics play a key role in poverty alleviation in Sichuan’s rural ethnic minority areas and to propose further measures to enhance the efficiency of e-commerce practice. To this end, we conduct an analysis using the framework of classic growth theory and use panel data from 2000 to 2018 to examine the relationship between Communication Infrastructure Investment (CII) and a set of poverty-alleviation indicators, including local GDP growth rate (LGGR), local government revenue (LGR), and per-capita income of residents (PCIR). The results indicate that strengthening CII improves the PCIR and local economic growth, playing a key role in poverty alleviation. However, the stimulation of CII on LGGR and LGR wanes as time passes. More financial and technical actions will be needed to improve the efficiency and quality of current strategies for sustainable development in those areas.

To achieve the dual goal of poverty alleviation and ecological restoration, the policy of ecological forest rangers (EFRs) was implemented in rural poverty-stricken areas in China, where local residents commonly depend on nearby forest resources for livelihoods. This study aimed to analyze the short-term and long-term effectiveness of the EFRs policy in China mainly in poverty alleviation and income growth, with a brief discussion on the ecological effect of the policy. A questionnaire survey was conducted in four counties in the Karst rocky desertification region in southwest China. By combing through the early literature on REDD+, community forestry, leasehold forestry, etc., this paper summarizes the experience and lessons of similar community forest management models, aiming to explain the unsustainability of EFRs policy from the perspective of forest tenure and governance. The findings of the effectiveness analysis of EFRs policy in the four poverty-stricken counties reflect different degrees of effect in rural households with different income levels. We believe that the EFRs policy has played important roles in short-term regional poverty alleviation while its potential for long-term income growth has not been stimulated. For the amendment of EFRs policy, we put forward the following points: (1) It is necessary to redesign the selection and recruitment mechanism, as well as the exit mechanism of EFRs adapting to the local conditions. (2) It is advisable to further improve the local assessment and monitoring system of forest protection quality of EFRs and optimize the establishment of benefit linkage mechanism between protection effectiveness and EFRs remuneration. (3) The EFRs remuneration standards should be dynamically raised to assure the active participation of EFRs in forest protection. Furthermore, there is a need for one more effective integration model of forest protection and rural livelihoods improvement, which is considered as a potential future research direction.

Chilli Veinal Mottle Virus

Chilli veinal mottle virus (ChiVMV), a potyvirus, is widespread over the world. In China, it was first reported in chili pepper (Capsicum annuum) in Hainan Province (south China) in 2006 (2). Subsequently, it was reported in tobacco (Nicotiana tabacum) in Yunnan Province (southwest China) in 2011 (1). Sichuan Province is one of the largest vegetable producing areas of China. In May 2012, tomatoes with leaves displaying virus-infected symptoms like mottling, mosaic, narrowing, or curling were observed in several fields of Chengdu, eastern Sichuan Province, southwest China. Of the 20 fields we investigated, four fields with 90% tomato plants were infected. During 2012 and 2013, six samples were collected from symptomatic tomato leaves based on different symptoms and locations. All six samples were assayed by western blotting using polyclonal antisera (Cucumber mosaic virus [CMV], Tobacco mosaic virus [TMV]) obtained from Agdia (Elkhart) and one antiserum to ChiVMV obtained from Yunnan Academy of Agricultural Science (China). Two samples from Pengzhou and one sample from Shuangliu exhibiting mosaic leaves were positive for TMV, one sample from Pixian exhibiting narrowing leaves was positive for CMV, and the other two samples from Shuangliu exhibiting mottle and leaf distortion were positive for ChiVMV. Total RNAs was extracted from all six samples and healthy tomato leaves using Trizol reagent (Invitrogen), First-strand cDNA synthesis primed with oligo(dT) by SuperScript III Reverse Transcriptase (Invitrogen). RT-PCR was performed using primer pairs ChiVMV-CP F (5′-GCAGGAGAGAGTGTTGATGCTG-3′) and ChiVMV–CP R (5′-(T)16AACGCCAACTATTG-3′), which were designed to direct the amplification of the entire capsid protein (CP) gene and 3′ untranslated region (3′-UTR) of ChiVMV (GenBank Accession No. KC711055). The expected 1,166-bp DNA fragment was amplified from the two tomato samples from Shuangliu that were positive for ChiVMV in the western blot tests, but not from the others. The obtained fragments were purified and cloned into the PMD18-T vector (TaKaRa) and sequenced. The sequencing results showed that the two ChiVMV isolates from tomato in Shuangliu were identical (KF738253). Nucleotide BLAST analysis revealed that this ChiVMV isolate shared ~84 to 99% nucleotide identities with other ChiVMV isolates available in GenBank (KC711055 to KF220408). To fulfill Koch's postulates, we isolated this virus by three cycle single lesion isolation in N. tabacum, and mechanically inoculated it onto tomato leaves. The same mottle and leaf distortion symptoms in systemic leaves were observed. Subsequent RT-PCR, fragment clone, and sequence determination tests were repeated and the results were the same. All the evidence from these tests revealed that the two tomato plants were infected by ChiVMV. To our knowledge, this is the first report of ChiVMV naturally infecting tomato in China. It shows that ChiVMV is spreading in China and is naturally infecting a new solanaceous crop in the southwest area, and the spread of the virus may affect tomato crop yields in China. Thus, it is very important to seek an effective way to control this virus. References: (1) M. Ding et al. Plant Dis. 95:357, 2011. (2) J. Wang et al. Plant Dis. 90:377, 2006.

BackgroundStreptococcus pneumoniae is an important pathogen causing high morbidity and high mortality in children and undergoes frequent recombination for capsule switching to neutralize the 13-valent pneumococcal conjugate vaccine (PCV13). This study aimed to investigate the prevalence, and molecular characteristics including serotypes and antibiotic susceptibility of S. pneumoniae isolated from children living in Southwest China from 2017 to 2019 to facilitate the selection of effective vaccine formulations and appropriate antibiotic treatment regimens.MethodsThis study was conducted at West China Second University Hospital (Chengdu, Sichuan Province, China), Zunyi Medical University Third Affiliated Hospital/First People’s Hospital of Zunyi (Zunyi, Guizhou Province, China) and Chengdu Jinjiang District Maternal and Child Healthcare Hospital (Chengdu, Sichuan Province, China). Demographic and clinical characteristics of children infected with S. pneumoniae were collected and analysed. Next-generation sequencing and sequence analysis were used to determine the serotypes, sequence types, antibiotic resistance and potential protein vaccine target genes of the pneumococcal isolates. The coverage rate provided by PCV13 was estimated by calculating the percentage of the specific serotypes that were specifically the PCV13-included serotypes. Antimicrobial susceptibility was determined by the microdilution broth method.ResultsThe most prevalent pneumococcal serotypes were 19F (25.8%), 19A (14.1%), 6B (12.5%), 6A (9.4%) and 14 (7.8%). The predominant STs were ST271 (23.3%), ST320 (15.5%) and ST90 (8.6%), dominated by the clonal complex Taiwan19F-14 (39.1%). The coverage rate of PCV13 was 77.3% in all the isolates, with relatively higher values in invasive isolates (86.4%). Over the decade, the rates of resistance to penicillin, amoxicillin and cefotaxime were 5.6%, 5.3% and 5.1%, respectively, with significantly higher values in invasive isolates (22.4%, 14.9% and 11.9%). Almost all the isolates were resistant to erythromycin (99.1%) and clindamycin (95.9%). All isolates carried virulence-related genes, including ply, psaA, piaA, piuA, phtE, nanA, pepO, danJ, pvaA, clpP, pcsB, stkP, potD, and strH. The carriage of virulence and resistance genes varied among serotypes and clades, with serotype 19F/ST271 showing higher resistance to antibiotics and being more likely to carry pilus genes and other virulence genes.ConclusionThese data provide valuable information for the understanding of pneumococcal pathogenesis, antimicrobial resistance and the development of protein-based vaccines against pneumococcal infection.
