Research Progress on Neo-endogenous Development in Rural Revitalization
LU Hai-yong;WANG Shuo;In the new era of the rural revitalization strategy, insufficient endogenous impetus in rural areas remains a prominent problem, and selecting appropriate development models has become critical to boosting rural development.Using literature analysis method and knowledge mapping method, this study systematically sorts out relevant literature on neo-endogenous development in rural China.The findings reveal that farmers are the core subjects of rural development.It is necessary to enhance cultural identity, foster shared values; awaken their internal motivation, enhance the endogenous empowerment of stakeholders, promote the effective integration of internal and external rural resources, and advance the joint participation of multiply entities in rural construction.A resilient rural governance system should be established.Nevertheless, existing studies mostly explore endogenous rural development from a single perspective, lacking a systematic framework for action.In the future, synergy theory can be introduced to conduct in-depth research on the theoretical framework and practical paths of rural neo-endogenous development, so as to provide sound theoretical support for achieving sustainable, resilient and inclusive neo-endogenous rural development.
Research Progress on Plant DNA Damage Response
ZHU Qiu-hua;LIN Yu-jie;CAO Rui;Plant DNA damage response(DDR) is a key mechanism for maintaining genome stability and coping with environmental stress.DNA double-strand breaks(DSBs) are the most serious DNA damage, which disrupting the physical continuity of chromosomes and resulting in the loss or mistransmission of genetic information.To repair such damages, two major DSBs damage repair mechanisms have evolved in eukaryotic cells: homologous recombination repair(HRR) and non-homologous end joining(NHEJ).In this paper, the latest research progress on the mechanisms of DNA damage response and DSBs damage repair in plants were reviewed.These mechanisms are essential for maintaining genome stability and integrity under stress conditions, and provide theoretical basis for improving crop stress resistance and breeding genetically improved varieties.

The Farmer Livestreaming Dilemma: A Theoretical Model of Price Premiums in Agricultural Livestreaming
ZHANG Yun-hui;TU Guo-ping;Fresh agricultural products have long been confronted with marketing challenges, which stem from their inherent perishability and significant supply-demand volatility. Although livestream e-commerce provides a potential solution to alleviate these obstacles and boost farmers' incomes, individuals engaged in self-operated livestreaming face multiple difficulties, such as non-standardized products, high perishability risks, post-sales uncertainties, and limited operational capabilities and resources. This study intends to conduct a theoretical analysis of the dilemmas inherent in farmers' self-operated livestream marketing. It explores the underlying mechanisms that impede income growth through livestreaming, with a specific focus on the impact of achieving a livestream premium on farmers' participation willingness. By employing a game-theoretic model that depicts the interaction between farmers and consumers, this research deduces the necessary conditions for a livestream price premium to drive income growth. It further assesses how these conditions differ across various operational scales and brand development stages. The results reveal that ordinary farmers—usually featured by small-scale operations, lack of brand awareness, and weak livestream operational capabilities—find it difficult to obtain a price premium high enough to offset additional sales costs and unrecovered investment in efforts. As a result, their effective income growth through livestreaming is often constrained.

Study on Gene Family Characteristics and Alpine Adaptive Evolution of Hemisteptia lyrata
XIONG Ye;WANG Heng-chang;The extreme environment of the Qinghai-Xizang Plateau,marked by high altitude cold,hypoxia and intense ultraviolet radiation,serves as a natural platform for dissecting the molecular mechanisms underlying the adaptive evolution of alpine plants.Hemisteptia lyrata,a basal taxon of the genus Saussurea,represents a pivotal model for investigating the early evolution of alpine Asteraceae species.Leveraging chromosome-level genome annotation data of H.lyrata,this study performed gene family clustering,phylogenetic reconstruction,and Gene Ontology(GO)/Kyoto Encyclopedia of Genes and Genomes(KEGG) functional enrichment analyses to identify core adaptation-related gene families and metabolic pathways.A total of 763 gene families underwent expansion and 1 174 underwent contraction in H.lyrata.Among these,246 significantly expanded families were enriched in pathways related to secondary metabolism and stress responses,including indole glucosinolate biosynthesis and glutathione metabolism.In contrast,341 significantly contracted families were concentrated in functions such as secondary metabolite synthesis and DNA replication.This study reveals that H.lyrata achieves broad-spectrum adaptation through a molecular strategy involving secondary metabolic specialization and optimized resource allocation,providing critical molecular evidence for understanding the evolution from widespread species to alpine specialists in Saussurea and alpine Asteraceae.

Optimization of Extraction Process and Antioxidant Activity of Origanum vulgare Volatile Oil Using Response Surface Methodology
LU Chao;CHEN Jing-xian;LU Shen-shen;[Objective] To optimize the extraction process of Origanum vulgare volatile oil and investigate its in vitro antioxidant activity. [Method] The yield of O. vulgare volatile oil extracted via ultrasound-assisted steam distillation served as the primary evaluation index. Key influencing factors were first screened through single-factor experiments, followed by optimization of extraction parameters using the Box-Behnken response surface methodology. Antioxidant capacity was assessed via 1,1-diphenyl-2-picrylhydrazyl(DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt(ABTS) radical scavenging assays, while the contents of carvacrol and thymol in the volatile oil were quantified using HPLC. [Result] Results indicated that the optimal extraction parameters were as follows: a salinity of 3.2%, liquid-solid ratio of 7∶ 1(mL∶ g), ultrasonic duration of 11 min, and extraction time of 92 min. Under these conditions, the extraction yield of O. vulgare volatile oil reached 4.724 mg/g. The volatile oil exhibited a certain degree of scavenging activity against both DPPH and ABTS radicals, though its scavenging efficacy was lower than that of vitamin C. HPLC analysis revealed that the extracted volatile oil contained 18.24% carvacrol and 6.38% thymol. [Conclusion] The Box-Behnken response surface methodology optimized extraction process for O. vulgare volatile oil is stable and reliable, providing a theoretical basis and technical reference for subsequent research on its antioxidant activity and development of practical applications.

The Mechanism,Constraints and Paths of Two-way Interaction Between New Rural Collective Economy and Rural Governance
WU Qi;ZHAO Huan;The new type of rural collective economy and rural governance are not only in a one-way empowering relationship,but also in a two-way interactive relationship of driving and feeding back. To clarify the specific process of the interactive relationship between the two, this paper adopts the research framework of “proposing hypotheses-analyzing hypotheses-verifying hypotheses”. After conducting a speculative analysis from the perspective of two-way interaction, it is found that the new rural collective economy has a very strong driving effect on rural governance, and rural governance also has a certain feedback effect on the new rural collective economy. Moreover, factors such as the low level of economic development, weak governance capacity and the absence of rural governance mechanisms affect the two-way interaction efficiency between the two. In the future,efforts should be made to further enhance the coordinated interaction between the development of the new rural collective economy and rural governance, improve the mechanism for transforming the economy into effective rural governance, and promote the smooth, stable and orderly transformation of the development level of the new rural collective economy into rural governance efficiency.
