Histone deacetylases (HDACs) play essential roles in modulating chromatin structure to provide accessibility to gene regulators. Increasing evidence has linked HADCs to pathogenesis control in the filamentous plant fungi. However, its function remains unclear in Fusarium pseudograminearum, which has led to the emergence of the disease Fusarium crown rot in China. Here we identified the FpDEP1 gene, an orthologue of Saccharomyces cerevisiae DEP1 encoding a component of the Rpd3 histone deacetylase complex in F. pseudograminearum. The gene deletion mutant, ΔFpdep1, showed significantly retarded growth on PDA plates with reduced aerial hyphae formation. Pathogenicity tests displayed no typical leaf lesions and limited expansion capability of coleoptiles. Histopathological analysis indicated the ΔFpdep1 deletion mutant differentiated infectious hyphae and triggered massive reactive oxygen species (ROS) accumulation during the early infection stage, resulting in limited expansion to neighbor cells which was concurring with sensitivity to H₂O₂ and SDS tests in vitro. FM4-64 staining revealed that the ΔFpdep1 deletion mutant was delayed in endocytosis. The FpDEP1-GFP transgene complemented the mutant phenotypes and the fusion protein co-localized with DAPI staining, indicating that the FpDEP1 gene product is localized to the nucleus in spores and mycelia. Immunoprecipitation coupled with LC-MS/MS and yeast two-hybrid screening identified the Rpd3L-like HDAC complex containing at least FpDep1, FpSds3, FpSin3, FpRpd3, FpRxt3, FpCti6, FpRho23, and FpUme6. These results suggest that FpDep1 is involved in a HDAC complex functioning on fungal development and pathogenesis in F. pseudograminearum.

Guided by the Theory of Planned Behavior (TPB; Ajzen, 1991), this study aimed to test a hypothesized path model of TPB variables (i.e., attitude toward behavior, subjective norm, perceived behavioral control, and intention) with physical activity (PA) and depressive symptoms. A total of 792 Chinese adolescents (M_age = 16.9; SD = 0.82; 54.5% females) completed previously validated questionnaires assessing their TPB variables, PA, and depressive symptoms. Correlation analysis revealed TPB variables were positively associated with PA (p < 0.01), and negatively correlated to depressive symptoms (p < 0.01). The path analyses indicated that the hypothesized model produces a goodness of fit (χ²/df = 16.14/5, CFI = 0.99, RMSEA = 0.06). The findings support the theoretical tenets of TPB and provide empirical evidence of the psychosocial mechanism of PA and depressive symptoms in Chinese adolescents. It suggests that building PA intervention strategies while considering the TPB framework may promote adolescents’ physical and mental health.

Recent developments regarding event portfolios have renewed research interest in the management and leveraging of sporting events. This study contributes to the topic by examining the purpose of sporting event portfolios and the process of their strategic planning in an Asian context – Shanghai. Guided by strategic planning theories, this paper explores how Shanghai’s sporting event portfolio was developed and why. Empirically, the study draws on extensive data, specifically, policy and strategy documents and interviews with key sport policymakers and sport experts in Shanghai. The results suggest that Shanghai’s event portfolio benefited from more than 20 years of planning and development. Twelve commercial sporting events were carefully handpicked and cultivated to promote destination branding, to advance Shanghai’s reputation as a global city, and to serve other social and economic development agenda. This study offers some important insights for the planning of event portfolios to enhance city image and stimulate regional development.

This paper examines the relationships between Olympic strategy, nationalism and legitimacy of the Party-state in China during a decade of reform. The analysis focuses on governmental policy prioritising elite sports and Olympic ambitions in the process of rebuilding the legitimacy of the Chinese Communist Party (CCP) following the Cultural Revolution (1966–1976). Drawing on Weber’s revised classification of legitimacy, this investigation contextualises sport and nationalism in the context of elite sport policy throughout the shift of political legitimacy in post-Mao China. Data were collected from a range of documents and seven semi-structured interviews. This study concludes that Chinese sporting excellence in the 1980s was closely associated with nationalism and the party’s political appeal. Thus, the pragmatic Party leaders of the time contended that performance-based legitimacy was more important and effective than Mao’s revolutionary ideology for transforming society in post-Mao China. Accordingly, China issued an Olympic strategy and strengthened its elite sport first policy, in the belief that sporting success in the 1980s would secure the satisfaction of the masses and also justify Deng’s pragmatism.

This paper examines Chinese sport policy and practice from 1949 to 1952 through an examination of the role of ideology in nation-building. Drawing on Gramsci’s theory of cultural hegemony, this study examines the nature of the ideological domination by the Chinese Communist Party (CCP) during this period and explores its sports policy and the political implications of this policy. Arguing that sport policy in the early years of the People’s Republic of China (PRC) was shaped by ideological requirements, the paper demonstrates that the CCP viewed sport as not only essential for physical wellbeing and discipline but also for the proper functioning and stability of the new regime. Nationalism, Maoism and Sovietization together dominated China’s sports policies in this period, though the CCP’s dominant ideology included a tendency towards pragmaticism. This mixed ideology, anchored in pragmatism, helped the party-state achieve ideological hegemony in the superstructure of Chinese society in the early years of PRC. Sports policy and its implementation became both a means of achieving this hegemony and a cultural reflection of the process.
