FeNS Single-Atom Sites Anchored on Three-Dimensional Porous Carbon for Highly Efficient and Durable Oxygen Electrocatalysis.

Precisely designing asymmetric active centers and exploring their electronic regulation effects to prepare efficient bifunctional single-atom catalysts (SACs) is important for boosting the practical applications of zinc-air batteries (ZABs). Herein, an effective strategy has been developed by introducing an axial S atom to the FeN active center, simultaneously assisted by pyrolyzing the graphene oxide (GO) sheathed zeolitic-imidazolate framework-8 (ZIF8) composite and constructing a three-dimensional (3D) porous framework with abundant FeNS moieties. This structure can accelerate the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) kinetics owing to the modulated electronic redistribution and -band center with a reduced energy barrier.

Hybridization affects the structure and function of root microbiome by altering gene expression in roots of wheat introgression line under saline-alkali stress.

The mutually beneficial relationship between plants and their root microbiota is essential for plants to adapt to unfavorable environments. However, the molecular mechanism of wheat regulating the structure of root microbiome and the influence of distant hybridization on this process are poorly understood. In this study, we systematically compared the root transcriptome and microbiome between a saline-alkali tolerant wheat introgression line SR4 (derived from somatic hybridization between wheat and tall wheatgrass) and its parent wheat variety JN177.

Effects of multiple N, P, and K fertilizer combinations on adzuki bean (Vigna angularis) yield in a semi-arid region of northeastern China.

Nitrogen (N), phosphorus (P), and potassium (K) exert various effects on adzuki bean yields. Our research was conducted in a semi-arid area, and four test sites were established in environments that have chernozem or sandy loam soils. During a five-year period, the effects of N, P, and K fertilizers on yield were comprehensively investigated in field trials (2014-2016) and for model-implementation trials (2017-2018), with models established prior to the latter.

Ccp1 Homodimer Mediates Chromatin Integrity by Antagonizing CENP-A Loading.

CENP-A is a centromere-specific histone 3 variant essential for centromere specification. CENP-A partially replaces canonical histone H3 at the centromeres. How the particular CENP-A/H3 ratio at centromeres is precisely maintained is unknown.
