[Effects of vertical rotary subsoiling with combined organic and inorganic fertilization on water use efficiency and yield of forage maize in a semi-arid area.].

Both reasonable soil tillage and fertilization management play critical roles in improving the yield and water use efficiency (WUE) of forage maize in the semi-arid area of Loess Plateau. A field experiment was conducted at Dingxi experimental station of Gansu Academy of Agricultural Sciences between 2017 and 2019. We explored the effects of tillage method and fertilization type on yields and WUE of forage maize, as well as the economic benefits.

[Effects of organic fertilizer application on flag leaf C/N ratio, photosynthetic characteristics and yield of spring wheat with full plastic film mulching].

A field experiment was conducted in the rain-fed semi-arid region of central Gansu in 2016 and 2017, with the treatments 1) hill-drop flat planting with full plastic film mulching (PMS), 2) hill-drop flat planting with full plastic film mulching plus organic fertilizers (PMO), and 3) hill-drop flat planting without soil mulching (CK). We investigated the relations among soil moisture, photosynthetic rate (), stomatal conductance () and transpiration rate (), C/N ratio, and total nitrogen of flag leaf from the heading stage to the seed-filling stage in different treatments to probe into their effects on the yield and yield components of spring wheat variety 'Longchun 27'. The results showed that organic fertilizer application could increase soil moisture at the middle and late growth stages of spring wheat.

Advances in studies on ion transporters involved in salt tolerance and breeding crop cultivars with high salt tolerance.

Soil salinity is a global major abiotic stress threatening crop productivity. In salty conditions, plants may suffer from osmotic, ionic, and oxidative stresses, resulting in inhibition of growth and development. To deal with these stresses, plants have developed a series of tolerance mechanisms, including osmotic adjustment through accumulating compatible solutes in the cytoplasm, reactive oxygen species (ROS) scavenging through enhancing the activity of anti-oxidative enzymes, and Na/K homeostasis regulation through controlling Na uptake and transportation.

Transcriptome and metabolome analysis reveals regulatory networks and key genes controlling barley malting quality in responses to drought stress.

Malting quality will be greatly deteriorated when barley plants suffer from post-anthesis drought stress, however there is a marked difference among barley genotypes in the responses of malting quality to drought stress, and the molecular mechanisms underlying the genotypic difference remain unclear. We made transcriptome and metabolome analysis on the developing grains of two barley genotypes differing in the responses to drought stress. Post-anthesis drought treatments led to decreased grain weight and β-glucan content, increased grain protein content and β-amylase activity.

Template-confined growth of Ruddlesden-Popper perovskite micro-wire arrays for stable polarized photodetectors.

The detection of the polarization states of light is of great significance for the analysis of biological tissue morphologies, image display systems and sensors. Although organic-inorganic hybrid perovskite crystals have excellent photoelectric properties, which make them very suitable for the preparation of photodetectors, their applications in polarized light detection are hindered by their isotropy and instability. Here, we solved this problem by fabricating a stable 2D layered Ruddlesden-Popper perovskite into anisotropic micro-wire arrays with a template-confined method.

Impacts of different soil fertility improvement practices with film mulched ridge-furrow til-lage on soil nutrient content, maize yield, and water use efficiency in Northwest China.

Improvement of soil quality is one of the most important ways to enhance fertility for efficient dryland crop production. However, the effects of different fertilization measurements with film mulched ridge-furrow tillage on soil fertility, crop yield, and water use efficiency (WUE) of maize largely remain unknown. A three-year field experiment was conducted at the Zhuanglang Experimental Station, Gansu Academy of Agricultural Sciences, located in the semiarid region of the Loess Plateau, Northwest China during 2014-2016.

Target therapy of TRIM-14 inhibits osteosarcoma aggressiveness through the nuclear factor-κB signaling pathway.

Osteosarcoma is the most common cause of cancer-associated mortality and the prognosis is yet to be fully elucidated due to the paucity of effective therapeutic targets that significantly influence the quality of life and mean survival rates of patients with osteosarcoma. Studies have showed that tripartite motif-containing (TRIM)-14 is a member of the TRIM protein family that has a vital role in tumor progression and metastasis and promotes angiogenesis, invasion and apoptotic resistance of bone cancer. In this study, a chimeric antibody targeting TRIM-14 (Chanti-TRIM) was constructed and the molecular mechanism of target therapy for TRIM-14 was investigated in osteosarcoma cells and xenograft mice.

Mfn2-Mediated Preservation of Mitochondrial Function Contributes to the Protective Effects of BHAPI in Response to Ischemia.

Disturbances in intracellular iron homeostasis are associated with neuronal injury after stroke. However, exposure of cells to classical chelators may interfere with physiological iron functions. BHAPI is an iron prochelator that exerts strong iron binding capacity only under oxidative stress conditions.

Sodium chloride enhances cadmium tolerance through reducing cadmium accumulation and increasing anti-oxidative enzyme activity in tobacco.

The effect of sodium chloride (NaCl) on cadmium (Cd) uptake, translocation, and oxidative stress was investigated using 2 tobacco cultivars differing in Cd tolerance. The growth inhibition of the tobacco plants exposed to Cd toxicity was in part alleviated by moderate addition of NaCl in the culture solution. Cadmium concentration of shoots and roots in the 2 cultivars increased with increasing Cd levels in the solution and decreased with the addition of NaCl.
