Environmental information disclosure is critical avenue for stakeholders to gauge the fulfillment of corporate environmental responsibilities, as well as a key path for companies to gain social reputation and achieve sustainable development. To achieve both economic and social sustainability and improve the environmental information disclosure by private firms, this study delves into the impact mechanism and realization path of mixed ownership reform on environmental information disclosure among Chinese private enterprises listed between 2010 and 2020. Utilizing a panel fixed effect model, we scrutinize the interplay between state capital involvement and the disclosure of environmental information by private enterprises. Our findings reveal that state capital involvement may encourage private enterprises to disclose environmental information through resource allocation and governance improvements. The higher the shareholding ratio of state-owned participating shareholders, the more it helps private firms to disclose environmental information. State-owned shareholders play a pivotal role in the appointment of supervisors, directors, and executives, effectively improving corporate governance mechanisms and positively moderates how private companies with state-owned capital participate in disclosing environmental information. Moreover, the magnitude of media coverage and the public opinion pressure faced by private enterprises further amplify the influence of state-owned capital involvement on environmental information disclosure. Additionally, our research reveals that corporate profitability partially interplays with the effects of state-owned capital disclosure of environmental information by private companies. According to the research results, we recommend that the government proactively promote mixed ownership reform with private enterprises as the main participants, fully leveraging the resource advantages and influence of state-owned capital. At the same time, it is imperative to strengthen the governance effect of internal state-owned shareholders and external public opinion supervision in private enterprises. Enhancing profitability is also identified as a key driver for private enterprises to engage in more robust environmental information disclosure practices. [ABSTRACT FROM AUTHOR]

Anthocyanin is a critical factor involved in coloration of plant tissues, but the mechanism how medium pH values affect anthocyanin accumulation in woody plants is unknown. We analyzed anthocyanin composition and the expression of elements encoding anthocyanin and flavonols biosynthesis underlying different medium pH values by using three different leave color type cultivars. HPLC analysis demonstrated that high medium pH values treatment induced a dramatic decrease in the concentration of cyaniding in crabapple leaves. Conversely, the high medium pH values induced up-regulation of the content of flavones and flavonols, suggesting that low pH treatment-induced anthocyanin accumulation. Quantitative real time PCR experiment showed the expression level of anthocyanidin synthase (McANS) and uridine diphosphate glucose flavonoid 3-O-glucosyltransferase (McUFGT) was up-regulated by low pH values treatment, and high medium pH value treatment up-regulate the transcription level of flavonol synthase (McFLS). Meanwhile, several MYB TFs have been suggested in the regulation of pH responses. These results strongly indicate that the low pH treatment-induced anthocyanin accumulation is mediated by the variation of mRNA transcription of the anthocyanin biosynthetic genes.
