The coevolution and coexistence of bacterial–fungal consortium have been widely reported in various natural ecosystems. The transboundary communication mediated by bacterial acyl–homoserine lactone signals probably is the driving force of fungal spore germination. This study aimed to report a functional bacterial signal molecule, C10-acyl homoserine lactone, which could be sensed by Galactomyces geotrichum. The spore germination rates of G. geotrichum increased by 22%. Meanwhile, carbohydrate production improved by 1.0-to 2.5-fold. G. geotrichum signaled to C10-HSL through receptor gene Rho1and made a response in cell wall assembly and carbohydrate biosynthesis by the upregulated expression(above 1-fold) of functional genes, such as Smi1, Utr2, and Chs2. It contributed to spore germination and morphology transformation together. This study provides a novel perspective for understating the transboundary cooperation between fungi and bacteria by cell-to-cell communication. 展开更多

This paper aims to understand China’s uneven regional development in recent years on the basis of on political economics theories.We summarizes two theories from the political economics on uneven regional development-framework of production and framework of exchange-and unifi es them by theories of labor value and capital circulation.It means to show that uneven regional development will be explained with value production,value realization and capital accumulation,and their interactions as well.This framework can not only explain regional disparities in a static sense,but also presents dynamically developments of regional disparities-first rising and then falling.Empirical research finds China’s regional disparities result mainly from the value production gap.During the period of analysis,China went through a capital accumulation biased towards less developed regions,jointly shaped by market logic and government behavior.It made the effect of reducing regional disparities stronger than the“polarization effect”around 2007,producing a narrowing of disparities across regional development. 展开更多

This study constructs a theoretical framework for understanding the new development paradigm based on value circulation and the reproduction theory of Marx.According to these theories,the essence of economic circulation is value circulation,the core of which is mutual matching among the structures of technological,distribution,demand,and production.We adopted a three-sector reproduction model with fixed capital to understand different development paradigms under various combinations of the four aforementioned structures.On this basis,we use the 1957-2017 input-output table to construct the three-sector tables and explain the logic of China’s economic structure change and the characteristics of the resulting circulation patterns.We also compared the economic structures and circulation patterns of the United States and Japan with those of China to shed light on China’s choice of future economic circulation patterns and the new development paradigms. 展开更多

Nonconventional luminescent materials have been rising stars in organic luminophores due to their intrinsic characteristics,including water-solubility,biocompatibility,and environmental friendliness and have shown potential applications in diverse fields.As an indispensable branch of nonconventional luminescent materials,polysiloxanes,which consist of electron-rich auxochromic groups,have exhibited outstanding photophysical properties due to the unique silicon atoms.The flexible Si-O bonds benefit the aggregation,and the empty 3d orbitals of Si atoms can generate coordination bonds including N→Si and O→Si,altering the electron delocalization of the material and improving the luminescent purity.Herein,we review the recent progress in luminescent polysiloxanes with different topologies and discuss the challenges and perspectives.With an emphasis on the driving force for the aggregation and the mechanism of tuned emissions,the role of Si atoms played in the nonconventional luminophores is highlighted.This review may provide new insights into the design of nonconventional luminescent materials and expand their further applications in sensing,biomedicine,lighting devices,etc. 展开更多
