Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.

Background And Aims: The whole-plant economics spectrum (PES) describes coordination between organ-level traits that together determine resource use strategies and is relevant for understanding plant responses to environmental change. Whereas coordination between organs has previously been explored across species, it remains unclear whether patterns observed across species hold within species. In addition, the key driving forces underlying this coordination warrant clarification.

Donghu Experimental Station of Lake Ecosystems, Key Laboratory of Breeding Biotechnology and Sustainable Aquaculture (CAS), Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan, China.

Investigating how multiple invasive fish species with similar ecological traits respond to different environmental conditions is crucial to understanding their successful invasion and coexistence. Here, we used stomach content analysis and stable isotope analysis to analyse the effects of water level fluctuation on the trophic niche plasticity of three dominant co-occurring invasive tilapia species (Coptodon zillii, Sarotherodon galilaeus, and Oreochromis niloticus) in the Shanmei Reservoir, southern China. We found that the tilapia species exhibited an iliophagous habit with dietary variations between the high-water (HW) and low-water (LW) level periods.

Microplastics (MPs) contamination is pervasive in agricultural soils, significantly influencing carbon and nitrogen biogeochemical cycles and altering greenhouse gas (GHG) fluxes. This review examines the sources, status, mechanisms, and ecological consequences of MPs pollution in agricultural soils, with a focus on how MPs modified soil physicochemical properties and microbial gene expression, ultimately impacting GHG emissions. MPs were found to reduce soil water retention, decreasing soil respiration and increasing emissions of CO, CH₄, and NO.

Article Synopsis
  • The study examined the effects of dietary saffron petal extract on laying hens over 12 weeks, focusing on egg quality, blood metabolites, and odor emissions from waste.
  • Results revealed that while egg protein, fat, and ash content remained mostly unchanged, a significant reduction in yolk cholesterol was observed, along with improved egg production in hens fed the 80 ppm saffron diet.
  • Supplementation with saffron petal extract also lowered serum cholesterol and blood glucose levels, but did not significantly affect feed intake or mineral excretion.

Infection behaviors of some susceptible and resistant Diaporthe citri isolates against two fungicides such as benomyl and kresoxim-methyl were observed on citrus leaves. On the chemically unsprayed leaves, there were no differences in not only the conidial germination rate but also hyphal growth between the resistant and susceptible isolates. However, on the benomyl or kresoximmethyl-pretreated leaves, both conidial germination rate and hyphal growth of the resistant isolates were not decreased, which was different with those of the susceptible isolates.

Accurate and effective monitoring of potentially toxic elements (PTEs) in soil across vast regions is crucial for environmental modeling and public health. While remote sensing (RS) technology provides a promising approach by detecting soil spectrum, dense and persistent vegetation cover in subtropical agricultural areas hinders acquisition of bare soil signals, limiting soil PTEs monitoring. To address this challenge, the present study proposed an innovative method for monitoring soil arsenic (As) content by using vegetation characteristics retrieved from RS data as proxy variables, given soil-vegetation interactions.
