Physiological mechanism of melatonin attenuating to osmotic stress tolerance in soybean seedlings.

Drought is one of the most significant abiotic stress threatening to crop production worldwide. Soybean is a major legume crop with immense economic significance, but its production is highly dependent on optimum rainfall or abundant irrigation. As the global climate changes, it is more important to find solutions to make plants more resilient to drought.

Maize-soybean intercropping at optimal N fertilization increases the N uptake, N yield and N use efficiency of maize crop by regulating the N assimilatory enzymes.

Introduction: Surplus use of chemical nitrogen (N) fertilizers to increase agricultural Q9 production causes severe problems to the agricultural ecosystem and environment. This is contrary to N use efficiency and sustainable agricultural production.

Methods: Hence, this study was designed to investigate the effect of maizesoybean intercropping on N uptake, N yield, N utilization use efficiency, and the associated nitrogen assimilatory enzymes of maize crops under different N fertilization for two consecutive years 2021-2022.

Effects of soaking seeds in exogenous vitamins on active oxygen metabolism and seedling growth under low-temperature stress.

This study investigated the influence of the exogenous application of vitamin B2 (V), B12 (V), biotin (V), and nicotinic acid (V) on oxygen production in maize ( L.) seedlings at 5 °C for day 1, 3, 5 and 7. The seeds were soaked in V, V, V, and V solutions for 24 h at the concentration of 100 mg/L, and control was soaked in distilled water.

[Effects of Enhanced Ultraviolet B Irradiation on Photosynthetic and Antioxidant System of Sorghum Seedlings].

The UV-B radiation on the surface of our planet has been enhanced due to gradual thinning of ozone layer. The change of solar spectrum UV-B radiation will cause damage to all kinds of terrestrial plants at certain degree. In this paper, taking breeding sorghum (Sorghum bicolor (L.

[Alleviation of salt stress during maize seed germination by presoaking with exogenous sugar].

The maize variety Kenyu 6 was used to study the effects of exogenous glucose (Glc) and sucrose (Suc) on salt tolerance of maize seeds at germination stage under 150 mmol · L(-1) NaCl treatment. Results showed that under salt stress condition, 0.5 mmol · L(-1) exogenous Glc and Suc presoaking could promote seed germination and early seedling growth.

Increased permeability of the blood-brain barrier and Alzheimer's disease-like alterations in slit-2 transgenic mice.

Alzheimer's disease (AD) is a progressive neurological disorder that primarily affects memory, and its prevalence is rising. Increasing evidence suggests that dysfunction of the blood-brain barrier (BBB) may be involved in AD and other neurodegenerative diseases. Herein, we report that the permeability of the BBB is increased and that AD-like alterations are present in Slit-2 overexpressing transgenic mice.

Identification of defense-related genes in rice responding to challenge by Rhizoctonia solani.

Rice sheath blight, caused by Rhizoctonia solani is one of the major diseases of rice. The pathogen infects rice plants directly through stomata or using lobate appressoria and hyphal masses called infection cushions. The infection structures were normally found at 36 h post-inoculation.

[Optimization of T-dNA insertional mutagenesis and analysis of mutants of Magnaporthe grisea].

The rice blast fungus Magnaporthe grisea causes one of the most destructive diseases of rice around the world. Significant progresses have been made recently in genomics studies of the fungus, opening new era of the functional genomics which requires to generate a large scale of gene knockout mutants. It has been demonstrated that T-DNA insertional mutagenesis is a powerful tool of functional genomics not only for plants but also for fungi.
