Abstract
Background
Rhizosphere microorganisms are key regulators of plant growth, stress tolerance, and secondary metabolism. However, whether soil microbial communities influence lutein and zeaxanthin biosynthesis in maize remains unclear.
Results
Analysis of rhizosphere microbial communities revealed that maize varieties rich in lutein- and zeaxanthin harbored greater soil microbial diversity and richness compared to common varieties. Distinct bacterial taxa enriched in these rhizospheres included the phylum Methylomirabilota and the genera Xanthobacteraceae, MB-A2-108, Rokubacteriales, and Acidothermus. Specific fungal genera comprised Didymella, Coprinellus, Trichoderma, Clonostachys, Poaceascoma, Arachniotus, Monocillium, along with several unclassified taxa within Chytridiomycota, Pleosporales, GS13, Agaricomycetes, Polyporales. Most of these specific bacterial and fungal genera correlated positively 0with lutein and zeaxanthin contents.
Conclusions
Our findings demonstrate that rhizosphere microbial community composition differs in high-lutein and zeaxanthin maize variety, suggesting a potential association between maize genotype, rhizosphere microbiota, and carotenoid accumulation.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
