The single-cell chromatin landscape in gonadal cell lineage specification.

Gonad development includes sex determination and divergent maturation of the testes and ovaries. Recent advances in measuring gene expression in single cells are providing new insights into this complex process. However, the underlying epigenetic regulatory mechanisms remain unclear.

Genome-wide 5-hydroxymethylcytosine (5hmC) reassigned in Pten-depleted mESCs along neural differentiation.

DNA methylation and hydroxymethylation have been implicated in the regulatory dynamics of gene expression in normal development and differentiation. 5-Hydroxymethylcytosine (5hmC), created by the ten-eleven translocation (TET) protein-catalyzed oxidation of 5-methylcytosine (5mC), is abundant in the brain, but the genome-wide distribution and impact of 5hmC during diverse neuronal differentiation remain unknown. Here, we used an model to differentiate mouse embryonic stem cells (mESCs) into ventral midbrain and hindbrain neural progenitors, followed by characterizing global 5hmC distribution using a nano-5hmC-seal approach.

Dyella dinghuensis sp. nov. and Dyella choica sp. nov., isolated from forest soil.

Two aerobic, Gram-stain-negative, non-motile, rod-shaped bacterial strains, designated as DHOA06 and 4 M-K27, were isolated from soil samples collected from the forest of Dinghushan Biosphere Reserve, Guangdong Province, PR China (112° 31' E 23° 10' N). Strains DHOA06 and 4 M-K27 grew at pH 4.5-7.

Aliidongia dinghuensis gen. nov., sp. nov., a poly-β-hydroxybutyrate-producing bacterium isolated from Pinus massoniana forest soil.

A Gram-stain-negative, aerobic, motile, rod-shaped bacterium, designated 7M-Z19T, was isolated from a soil sample collected from a Pinus massoniana forest of Dinghushan Biosphere Reserve, Guangdong Province, PR China. Strain 7M-Z19T grew at pH 4.5-7.
