About this Research Topic
The ability of ISR-eliciting microbes to trigger both defense responses and nutrient deﬁciency responses opens the possibility to use them as biopesticides and as nutrient biofertilizers. This presents a very important opportunity to reduce the application of fertilizers and pesticides for a more sustainable agriculture. However, the use of ISR-eliciting microbes is in its infancy since the behavior of these microbes on crops grown in soils is not suﬃciently known. Most research about the relationship of these microbes with plant mineral nutrition has been carried out using Arabidopsis plants grown on agar plates. For application of ISR microbes to crop plants in the ﬁeld, it also is also necessary to study the behavior of these microbes with plant species growing in soils, including their capacity to thrive in these soils and to compete with wild soil microbes.
Papers submitted to this article collection must report new results and the latest findings related to the roles of ISR eliciting microbes on mineral nutrition in crops.
We particularly welcome manuscripts dealing with the following topics:
• New non-symbiotic microbes able to induce responses aimed to facilitate nutrient acquisition.
• Symbiotic microbes (mycorrhizal fungi, nitrogen fixing bacteria...) able to induce gene expression related to nutrient deficiency responses.
• Cross-talk with hormone signalling implicated in nutrient deficiency responses regulation.
• Methods for the application of ISR eliciting microbes: by soil inoculation, plantlet root immersion, seed coating or irrigation.
• Effects of the inoculation of individual versus multiple species microbial consortia.
All forms of submissions (i.e. original research papers, Mini Reviews, Methods, Perspectives, Hypothesis and Theories, and Opinion Articles) are welcome.
