Exploring microbial signals and biotechnology for rhizosphere engineering, biological control and efficient plant growth
The use of beneficial microorganisms, such as plant growth promoting microorganisms, has been proposed as an ecofriendly strategy to promote sustainable maintenance of plant and soil health and enhance agroecosystems. This research topic explores the potential of plant growth promoting rhizobacteria (PGPR) to improve crop growth and yield in various environmental conditions, including saline and saline sodic soils, and low-input cultivation practices.
The research has found that PGPR can increase grain yields, promote plant growth, reduce ethylene levels, increase nutrient availability, and improve soil structure and health. In addition, the use of bacterial consortia has been found to be an effective and safe alternative to chemical fertilization, and the inoculation of Azospirillum brasilense has been found to improve crop productivity in intercropped systems. Furthermore, the use of rhizobia and other beneficial bacteria has been found to enhance soybean production, and Pseudomonas koreensis AEPR1 has been found to significantly enhance rice growth.
Overall, the research has found that beneficial microorganisms can be used to improve crop growth and yield in a variety of environmental conditions, and can potentially replace chemical fertilizers in commercial agriculture. Further research is needed to understand the mechanisms behind plant-microbe interactions, and to develop context-appropriate technologies for smallholder farms.
