Entrepreneurship and high-quality economic development: based on the triple bottom line of sustainable development

Abstract: High-quality development has recently become an inevitable requirement for sustainable and healthy economic development in China, which pursues a sustainable ecology and a happy society for people while developing economy Entrepreneurship is believed to be the essence of enterprise and one of the important factors of social economic development This paper uses triple bottom line of sustainable development to measure high-quality economic development and studies the mutual influences between entrepreneurship and triple bottom line of sustainable development Furthermore, this paper uses three moderating variables to study the moderation effect, including business environmental index, environmental regulation and foreign direct investment The empirical results show that there exists a close relationship between entrepreneurship and triple bottom line of sustainable development There are different influences of entrepreneurship and triple bottom line of sustainable development in different areas in China The results also show that the business environment and foreign direct investment not only have direct impacts but also moderation effects on entrepreneurship towards triple bottom line of sustainable development Environmental regulation affects environmental pollution only by the moderation effect towards entrepreneurship, and the effects are different in various areas

Ultraviolet-B-induced flavonoid accumulation in Betula pendula leaves is dependent upon nitrate reductase-mediated nitric oxide signaling

Abstract: Nitric oxide (NO) is an important signaling molecule involved in many physiological processes in plants. Nitric oxide generation and flavonoid accumulation are two early reactions of plants to ultraviolet-B (UV-B) irradiation. However, the source of UV-B-triggered NO generation and the role of NO in UV-B-induced flavonoid accumulation are not fully understood. In order to evaluate the origin of UV-B-triggered NO generation, we examined the responses of nitrate reductase (NR) activity and the expression levels of NIA1 and NIA2 genes in leaves of Betula pendula Roth (silver birch) seedlings to UV-B irradiation. The data show that UV-B irradiation stimulates NR activity and induces up-regulation of NIA1 but does not affect NIA2 expression during UV-B-triggered NO generation. Pretreatment of the leaves with NR inhibitors tungstate (TUN) and glutamine (Gln) abolishes not only UV-B-triggered NR activities but also UV-B-induced NO generation. Furthermore, application of TUN and Gln suppresses UV-B-induced flavonoid production in the leaves and the suppression of NR inhibitors on UV-B-induced flavonoid production can be reversed by NO via its donor sodium nitroprusside. Together, the data indicate that NIA1 in the leaves of silver birch seedlings is sensitive to UV-B and the UV-B-induced up-regulation of NIA1 may lead to enhancement of NR activity. Furthermore, our results demonstrate that NR is involved in UV-B-triggered NO generation and NR-mediated NO generation is essential for UV-B-induced flavonoid accumulation in silver birch leaves.
