Abstract :
基于2011—2021年中国沪深A股上市企业的面板数据,采用固定效应模型和中介效应模型实证检验数字化转型对企业可持续发展的影响,以及内部控制、绿色创新、融资约束在数字化转型对企业可持续发展影响中的中介效应。研究发现:数字化转型有益于企业可持续发展,经过内生性及稳健性检验后,该结论依然成立;从作用机制来看,企业的数字化转型通过改善企业内部控制质量、提高绿色创新动能、缓解融资约束等进一步促进企业可持续发展;从异质性分析来看,相比于大企业和国有企业,数字化转型对中小企业和非国有企业可持续发展的正向促进作用更大。据此,提出企业要落实数字化转型战略,政府要升级政策保障措施等,以推进企业可持续发展。

Abstract :
Cry toxins produced by Bacillus thuringiensis (Bt) are well known for their insecticidal activities against Lepidopteran, Dipteran, and Coleopteran species. In our previous work, we showed that trypsin-digested full-length Cry7Ab4 protoxin did not have insecticidal activity against Plutella xylostella larvae but strongly inhibited their growth. In this paper, we expressed and purified recombinant active Cry7Ab4 toxic core from Escherichia coli for bioassay and identified its binding proteins. Interestingly, Cry7Ab4 toxic core exhibited activity to delay the pupation of P. xylostella larvae. Using protein pull-down assay, several proteins, including basic juvenile hormone-suppressible protein 1-like (BJSP-1), were identified from the midgut juice of P. xylostella larvae as putative Cry7Ab4-binding proteins. We showed that feeding P. xylostella larval Cry7Ab4 toxic core upregulated the level of BJSP-1 mRNA in the hemocytes and fat body and decreased the free juvenile hormone (JH) level in larvae. BJSP-1 interacted with Cry7Ab4 and bound to free JH in vitro. A possible mechanism of Cry7Ab4 in delaying the pupation of P. xylostella larvae was proposed.

Abstract :
以我国林业经济高质量发展和森林生态文明建设为背景,从森林经济效益、生态环境效益、科技驱动效益三方面着手构建森林生态与科技评价指标体系,运用熵权法测算各指标权重和综合得分,并依次结合时间趋势外推法、年平均增长率推算法、平均值推算法、德尔菲法来推算2020年的实现程度。研究发现:我国森林生态与科技效益逐年提高,符合生态文明整体发展趋势。在生态文明视角下,要想达到2020年实现程度,部分指标有待进一步强化,尤其是在林业就业水平、科技投入、生态旅游方面,更需要加大建设力度。

Abstract :
运用层次分析法和模糊综合评价法,构建了由经济、社会、文化、生态及管理可持续发展5个二级评价指标、41个三级评价指标构成的林区文创旅游可持续发展评价指标体系,并以福建省宁德市屏南县龙潭村为样点论证了评价指标体系的科学和合理。研究表明:龙潭村文创旅游可持续发展水平处于基本可持续发展阶段,政府支持显著、生态环境优美、社会治理和谐、党委领导创新有力;但依旧存在文创活动参与感不突出、文化内涵挖掘不足、环境保护宣传工作欠缺、居民参与意愿和能力不匹配等薄弱之处。因此,建议制定林区文创旅游专项扶持政策,畅通多元共治途径,创新林区发展模式,加大林区文创活动宣传,科学规划设计文创产品,深入挖掘文化内涵,加大环境整治力度,重视林区人力资本建设,完善林区文创旅游人才引入机制,以提高林区文创旅游发展的可持续性。

Abstract :
Basic helix-loop-helix (bHLH) transcription factors play an important role in a wide range of metabolic and developmental processes in eukaryotes, and bHLH proteins also participate in immune responses, especially in plants. However, their roles in insects upon entomopathogen infection are unknown. In this study, 54 bHLH genes in 41 families were identified in a polyphagous pest, Spodoptera litura, including a new bHLH gene in group B, which is specifically present in Lepidoptera and was thus named Lep. The conserved amino acids in the bHLH domain, structural architecture, and chromosomal distribution of bHLH genes in S. litura were analyzed. The bHLH genes in Plutella xylostella and Apis mellifera were also updated, and genome-wide comparison and phylogenetic analysis of bHLH members in 5 holometabolous insects were performed. The expression profiles of S. litura bHLH (SlbHLH) genes in 3 tissues at different developmental stages and their responses to S. litura nucleopolyhedrovirus (SpltNPV), Nomuraea rileyi (Nr), and Bacillus thuringiensis (Bt) infection were investigated. More SlbHLHs in group B were expressed and differentially expressed during pathogen infections, and SlbHLHs tended to be downregulated in the midgut of S. litura larvae after B. thuringiensis treatment. Our study provides an overview of bHLH family members in S. litura and their responses to different pathogens used for pest biocontrol. These findings on bHLH members may contribute to uncovering the mechanism of host-pathogen interaction.

Abstract :
Cadherin, aminopeptidase N (APN) and alkaline phosphatase (ALP) have been characterized as Cry receptors. In this study, comparative genomic analysis of the 3 receptor families was performed in 7 insects. ALPs and APNs are divided into three and eight clades in phylogenetic trees, respectively. ALPs in clade 3 and APNs in clade 1 contain multiple paralogs within each species and most paralogs are located closely in chromosomes. Drosophila melanogaster has expanded APNs in clade 5 and were lowly expressed in midgut. Cadherins are divided into 16 clades; they may diverge before holometabolous insect speciation except for BtR and Cad89D-like clades. Eight insects from different orders containing BtR orthologs are sensitive to Cry1A or Cry3A, while five species without BtR are insensitive to both toxins. Most APNs in clade 1, several ALPs in clade 3, BtR and Cad89D-like genes were highly or moderately expressed in larval midgut of Spodoptera litura and the other six species, and several members in these clades have been identified as Cry receptors. Expressions of putative S. litura Cry receptors in the midgut after exposing to Bt toxins were also analyzed.

Abstract :
从森林资源效益、科技创新效益、人力资本效益3方面出发,构建中国森林资源发展质量评价指标体系,然后基于熵权法与空间自相关分析法测算中国森林资源发展质量的驱动力指数并分析其区域间的时空差异。结果发现:中国省域森林资源发展质量处于中等水平,空间异质性突出,其中林业科技水平普遍较低,且人力资本效益主要集中于东南地区。为此,政府部门要加强森林资源发展质量监督,重视林业科技创新和人力资本的培养,形成以局部带动总体的发展模式消除区域间森林资源发展质量不平衡问题。
