Positive effect of inoculation with an Aspergillus strain on phosphorus and iron nutrition plus volatile organic compounds in rice.
We explored the potential of a fungal strain Aspergillus costaricensis KS1 for modulating growth and nutrient mobilization in rice. At laboratory conditions, there was a decline in pH of the medium on inoculation with the strain and the production of citric acid was observed under broth conditions. Similarly, there was higher solubilization of tricalcium phosphate and siderophore production in liquid medium on inoculation with the strain. The effect of inoculation of KS1 was studied in rice and higher growth and yield were observed on inoculation compared to control. The content of phosphorus and iron in stem and roots of KS1 inoculated plants was higher in comparison with uninoculated control. There was also increased availability of phosphorus and iron content in soil grown with KS1 inoculated plants. In addition, inoculation with strain resulted in a higher content of volatile organic compounds such as linoleic acid, linolenic acid, and ethyl isoallocholate in stem of rice. A. costaricensis KS1 can be used for improving phosphorus and iron nutrition and impart tolerance against stresses in rice.
期刊介绍:
Unlike journals which specialize ever more narrowly, Folia Microbiologica (FM) takes an open approach that spans general, soil, medical and industrial microbiology, plus some branches of immunology. This English-language journal publishes original papers, reviews and mini-reviews, short communications and book reviews. The coverage includes cutting-edge methods and promising new topics, as well as studies using established methods that exhibit promise in practical applications such as medicine, animal husbandry and more. The coverage of FM is expanding beyond Central and Eastern Europe, with a growing proportion of its contents contributed by international authors.
