The NH₂-Ti₃C₂Tₓ was prepared by grafting (3-amino-propyl) triethylsilane (APTES) onto the surface of Ti₃C₂Tₓ. Its morphology, crystal structure and chemical composition were characterized by field emission scanning electron micr ...
... Microplastic contamination poses a significant threat to agroecosystem functioning, provoking a move away from the use of conventional oil-based plastics in agriculture, to biodegradable alternatives that may be degraded over a shorter timescale. The impact of these bioplastics on plant and soil health, however, has received relatively little attention. Here, we investigated the effect of soil loa ...

ZCP stabilized Pickering emulsions encapsulating citral and/or cinnamaldehyde (ZCP-CT, ZCP-CN, ZCP-CTCN) were constructed as an effective antimicrobial system, and the stability and antifungal properties were evaluated. When the ratio of zein to chitosan was 20:1, the emulsion showed good ...
... Most physiology-based crop simulation models do not simulate grain quality dynamics other than protein content. In this study, a simple algorithm was adapted for predicting starch, oil, and protein content of two maize cultivars using four years of experimental data performed in northern Iran. Quality modelling was performed in two steps: (a) the APSIM-Maize model was used to dynamically simulate ...
... Ochratoxin A (OTA) is a fungal secondary metabolite produced by certain species of Aspergillus and Penicillium, and is generally found in contaminated grains, presenting considerable risks to human and animal health.

However, little is known about the gut immune responses to the environment, particularly along the migration routes in Jianghuai, China, throughout the autumn and winter. In this study, high-throughput sequencing and real-time quantitativ ...
... Excessive N fertilization causes the deterioration of soil microbiome. It is therefore imperative to explore the response of the microbial community in excessively N-fertilized soil to reduce subsequent N supply (RCN) and organic fertilization (OF). Hence, this study used an excessively N-fertilized plot to conduct field experiment of wheat and maize rotation over four years to assess the effects ...

The effects of temperature, incubation time and pH wer ...
... Monoculture farming pollutes the environment by increasing the use of inputs, accelerating soil erosion, polluting water resources, raising carbon level in the atmosphere, and decreasing biodiversity. Therefore, farmers are advised to implement diversified farming systems such as crop rotation. However, crop rotation, i.e., planting more than one crop in the same field over a given year, may also ...

However, there is still a limited understanding of how well protist isolation efforts can capture the diversity and composition of rhizosphere protistan communities. Here, we report a simultaneous isolation and 18S rRNA gene amplicon sequencing su ...
... Maize (Zea mays L.) is a major cereal crop grown in a large number of countries. Loss in maize yield due to biotic stresses including fungal phytopathogens is a matter of immense concern. Control measures applied for eradication of fungal phytopathogens in maize are not up to the mark and more often involve harsh chemical(s)/pesticide(s) that cause deleterious effects both in humans and soil biota ...
... Aluminum (Al) is a major environmental stress that limits crop growth and production. 24-Epibrassinolide (EBR) can control stress responses, but how it regulates Al homeostasis in Al-stressed maize seedlings is poorly understood. Therefore, seedlings of two lines of maize (Zea mays L.) under Al stress (60 μM AlCl₃) were treated with 1.0 × 10⁻⁶ M EBR. In roots exposed to Al, EBR helped protect memb ...

Experiment was carried out in three factorial randomized complete block design with a t ...
... Herbicides play key roles in agriculture. Aclonifen is a diphenyl ether herbicide that is widely used for sunflower, potato, corn, and wheat crops. Since it has a long half-life, it is considered persistent and can easily accumulate in the environment. Therefore, livestock and humans are at risk of exposure to aclonifen. Importantly, aclonifen is toxic to several mammals such as rats, mice, and do ...
