The mid-Proterozoic (1.8–0.8 Ga) witnessed the first appearance but unusually low
diversification of eukaryotes. The stagnant biotic evolution during this billion-year-long period (…

The two-component signal transduction system BarA-UvrY of Escherichia coli and its orthologs
globally regulate metabolism, motility, biofilm formation, stress resistance, virulence of …

The mid‐Proterozoic (∼1.8–0.8 Ga) is characterized by low atmospheric oxygen and
pervasive oceanic anoxia, with transient oxygenation events. One of the oxygenation events …

The relationship between oxygen and evolution of early eukaryotes including algae and
primitive animals in geological history has been debated, partly due to the varying estimates of …

Marine red beds (MRBs) are common in sedimentary records, but their genesis and
environmental implications remain controversial. Genetic models proposed for MRBs variably …

Xanthomonas campestris pathovar campestris (Xcc) is the causative agent of crucifer black
rot disease, which causes severe losses in agricultural yield world-wide. This bacterium is a …

Stratiform or layered siderites are much less common than siderite concretions in the
stratigraphic record. In the middle part of the Mesoproterozoic Xiamaling Formation (ca. 1.40–1.35 …

Marine carbonate fabrics are intrinsically related to ocean chemistry, physical processes and
biological activity. Molar tooth structure (MTS), a globally distributed structure in Proterozoic …

Organic carbon isotope (δ 13 C org ) data from two well-preserved sections across a shallow-to-deep
water transect of the late Ediacaran-Early Cambrian Yangtze Platform in South …

The crash prediction model is a useful tool for traffic administrators to identify significant risk
factors, estimate crash frequency, and screen hazardous locations, but some jurisdictions …
