Quality and Safety in Asparagus Cultivation: A Three-Year Case Study Comparing Standardized Agricultural Bases and Small-Scale Farmers.

To investigate the quality and safety difference between agricultural standardization bases and small-scale farmers, we carried out a three-year investigation of asparagus from seven production sites of different sizes in Pinghu city, Zhejiang Province, China, from 2021 to 2023. We documented trace elements (Fe, Zn, Mn, and Cu), quality indicators (vitamin B1, vitamin B2, vitamin C, total sugar, and proteins), and pesticide residues. The evaluation indicated that the quality of asparagus in standardization bases 1-4 was higher than that in small farmer sites 5-7.

The adsorption mechanism and optimal dosage of walnut shell biochar for chloramphenicol.

Biochar derived from biomass pyrolysis has proven to be an excellent material for pesticide adsorption and can be used as soil amendment for pesticide non-point pollution. However, the adsorption and desorption mechanisms for certain biochar and pesticide are still unclear. In this study, we investigated the properties of biochar derived from walnut (Juglans regia L.

Integrating transcriptome and metabolome reveals molecular networks involved in genetic and environmental variation in tobacco.

Tobacco (Nicotiana tabacum) is one of the most widely cultivated commercial non-food crops with significant social and economic impacts. Here we profiled transcriptome and metabolome from 54 tobacco samples (2-3 replicates; n = 151 in total) collected from three varieties (i.e.

QTL Mapping Combined With Bulked Segregant Analysis Identify SNP Markers Linked to Leaf Shape Traits in Using SLAF Sequencing.

Leaf shape is an important trait that influences the utilization rate of light, and affects quality and yield of pea (). In the present study, a joint method of high-density genetic mapping using specific locus amplified fragment sequencing (SLAF-seq) and bulked segregant analysis (BSA) was applied to rapidly detect loci with leaf shape traits. A total of 7,146 polymorphic SLAFs containing 12,213 SNP markers were employed to construct a high-density genetic map for pea.

Integrating Genetic and Gene Co-expression Analysis Identifies Gene Networks Involved in Alcohol and Stress Responses.

Although the link between stress and alcohol is well recognized, the underlying mechanisms of how they interplay at the molecular level remain unclear. The purpose of this study is to identify molecular networks underlying the effects of alcohol and stress responses, as well as their interaction on anxiety behaviors in the hippocampus of mice using a systems genetics approach. Here, we applied a gene co-expression network approach to transcriptomes of 41 BXD mouse strains under four conditions: stress, alcohol, stress-induced alcohol and control.

Assessment of heavy metal pollution in vegetables and relationships with soil heavy metal distribution in Zhejiang province, China.

There are increasing concerns on heavy metal contaminant in soils and vegetables. In this study, we investigated heavy metal pollution in vegetables and the corresponding soils in the main vegetable production regions of Zhejiang province, China. A total of 97 vegetable samples and 202 agricultural soil samples were analyzed for the concentrations of Cd, Pb, As, Hg, and Cr.
