Compost-based organic fertilizers made from animal manures may contain high levels of antibiotic resistance genes (ARGs). However, the factors affecting the abundance and profile of ARGs in organic fertilizers remain unclear. We conducted a national-wide survey in China to investigate the effect of material type and composting process on ARG abundance in commercial organic fertilizers and quantified the contributions of bacterial composition and mobile genetic elements (MGEs) to the structuring of ARGs, using quantitative PCR and Illumina sequencing of 16S rRNA gene amplicons.

- Plant roots play a crucial role in transferring atmospheric carbon to soils through rhizodeposits and root exudates, impacting microbial activity and nutrient cycling.
- Different root exudate types—amino acids, carboxylic acids, and sugars—have distinct effects on dissolved organic carbon (DOC) release and mineral interactions, influencing soil carbon dynamics.
- Chemical composition of root exudates shapes bacterial communities in the rhizosphere, affecting carbon cycling and the overall microbial diversity in the soil.
Yield and yield components in hybrid rice were investigated using AFLP, RAPD and SSR markers. Ten restorer and five male-sterile lines were crossed in all possible pairs resulting in 50 crosses. Positive loci, effect-increasing loci, effect-decreasing loci and non-environmental loci were selected from the 931 marker loci surveyed in the 15 parental lines and their correlation with yield and yield components were analyzed.
