Special Issue Information

Dear Colleagues,

One of the major challenges of the twenty-first century is the sustainable intensification of agricultural production that must be achieved by limiting the ecological footprint. The growing concerns of people over the intensive use of chemicals in agriculture are resulting in an increased attention towards more environmentally sound crop management. A better knowledge of plant-microbe-soil interaction can help us to move to more sustainable strategies and reduce the use of conventional chemicals in agriculture. On one hand, microbes can stimulate plant growth and can enhance plant health by reinforcing crop resilience to biotic or abiotic stresses. On the other hand, some microorganisms are plant pathogens, which endanger plant health and negatively affect crop production. Microbes also play a crucial role in plant-soil interactions, regulating factors in biogeochemical cycling of elements (carbon, nitrogen, and phosphorus) and contributing to ecosystem stability and environmental quality.

On these bases, the aim of this Special Issue is to cover state-of-the-art developments and recent progress in different aspects related to the plant-microbe-soil interactions in agroecosystems. We welcome the submission of all types of manuscripts (original research and reviews) that cover, but are not limited to, the following topics:

  • Plant effect on microbe-mediated ecological processes
  • Plant resistance, modulated by microorganisms, to biotic and abiotic stresses
  • Plant interaction with rhizosphere and phyllosphere microbiome
  • Next generation sequencing technologies to study plant–microbe interactions
  • Effect of microorganisms on plant yield and quality
  • Molecular mechanisms underlying plant-microbe interactions

Techniques such as intercropping and minimum tillage improve soil quality, including soil microbial activity, which stimulates the efficient use of soil resources by plants. However, the effects of such practices in soil under citrus orchards have not been well characterized. In this study, we aimed to determine the effects of mowing and intercrop species on soil microbiological characteristics beneath a Tahiti acid lime orchard. The orchard was planted using minimum tillage and intercropped with two species of Urochloa species (U. ruziziensis—ruzi grass; U. decumbens—signal grass), with two types of mowers for Urochloa biomass (ecological; conventional) and herbicide applications. The study was conducted over 10 years. The ecological mower made the largest deposition of the intercrop biomass, thus providing the lowest disturbance of soil microbial activity and increasing, on average over all 10 years, the basal soil respiration (45%), microbial biomass carbon (25%), abundance of 16S rRNA (1.5%) and ITS (3.5%) genes, and arbuscular mycorrhizal fungi (30%), and providing a ca. 20% higher fruit yield. U. ruziziensis in combination with ecological mowing stimulated the abundance of the genes nifH (1.5%) and phoD (3.0%). The herbicide showed little influence. We conclude that the use of U. ruziziensis as an intercrop in citrus orchards subjected to ecological mowing can be recommended for improving and sustaining soil quality and citrus fruit production.

The excessive use of fertilizers in agriculture is mainly due to the recognized plant requirements for soluble phosphorus. This problem has limited the implementation of sustainable agriculture. A viable alternative is to use phosphate solubilizing soil microorganisms. This work aimed to isolate inorganic phosphorus-solubilizing bacteria from the soils of agroecosystems, to select and identify, based on sequencing and phylogenetic analysis of the 16S rRNA gene, the bacterium with the highest capacity for in vitro solubilization of inorganic phosphate. Additionally, we aimed to determine its primary phosphate solubilizing mechanisms and to evaluate its effect on Habanero pepper seedlings growth. A total of 21 bacterial strains were isolated by their activity on Pikovskaya agar. Of these, strain ITCB-09 exhibited the highest ability to solubilize inorganic phosphate (865.98 µg/mL) through the production of organic acids. This strain produced extracellular polymeric substances and siderophores that have ecological implications for phosphate solubilization. 16S rRNA gene sequence analysis revealed that strain ITCB-09 belongs to the genus Enterobacter. Enterobacter sp. ITCB-09, especially when immobilized in beads, had a positive effect on Capsicum chinense Jacq. seedling growth, indicating its potential as a biofertilizer. Full article

In the most recent scientific reports based on the DNA or RNA-analyses a widespread presence of the filamentous fungi, Mortierella in various environments has been shown. Some strains of this genus belong to the plant growth-promoting fungi (PGPF) and are found in the bulk soil, rhizosphere and plants tissues. These microorganisms are also often found in the extremely hostile environments, responsible for improving access to the bioavailable forms of P and Fe in the soils, the synthesis of phytohormones and 1-aminocyclopropane-1-carboxylate (ACC) deaminase, and last but not least the protection of agricultural plants from pathogens. Furthermore, earlier reports classified Mortierella spp. as the saprotrophic microorganisms isolated from the forest litter, and nowadays their status as a very valuable decomposers in the agricultural soils was confirmed. The key features like the ability to survive under very unfavorable environmental conditions and the utilization of carbon sources contained in polymers like cellulose, hemicellulose, chitin make these fungi efficient as the agricultural inoculants. The growing interest in the application of Mortierella spp. is mainly due to the potential use of this genus in the increase of the nutrient uptake efficiency, positive effect in crop protection against adverse conditions, and reduction of chemical fertilizers and pesticides applied. Moreover, activities of Mortierella species selected from the wild or cultivated plants influence the soil microbiota and support the performance of the beneficial microorganisms enhancing significantly crop yield.
