Special Issue Information

Dear Colleagues,

Microorganisms are the most numerous beings that exist on Earth; they are essential for the functioning of ecosystems and maintain continuous interaction with plants. Some microorganisms may improve the availability of phosphorus and other nutrients, thus contributing to reduce the use of chemical fertilizers. Other microorganisms are capable of synthesizing and degrading plant growth regulators that aid plant growth. Many of them form symbiosis with plants to cope with abiotic and biotic stresses, intervening in processes such as biochemical, molecular and physiological changes, which improve the plant water status, nutrient acquisition and photosynthetic efficiency. Therefore, these microorganisms are biotechnological alternatives with great importance in terms of promoting sustainable agriculture for the benefit of the environment. However, for these microorganisms to be used as effective and sustainable tools for agriculture, numerous factors must be taken into account. Furthermore, the applicability of the microorganism–plant association is determined by the source of both the microorganism and plant species. Aspects such as the evaluation of microorganisms under multiple stressors and the identification of specific combinations of microorganism plant strains/species should be considered to obtain the most effective responses. On the other hand, the molecular and genetic mechanisms which control the plant–microorganism interaction are still unclear.

In this Special Issue, original research articles and reviews are welcomed. Research areas may include (but are not limited to) recent advances related to the interaction between microbes and plants, including those performing symbiosis with the plant, and the effects of the application of microorganisms on plant physiology, crop production and quality under biotic and abiotic stresses. The role of individual or consortium microbes, the molecular mechanisms involved in the plant–microorganism interaction and the exploitation of new technological and sustainable approaches to understand the interactions between plant microbes are also welcomed.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Intensive use of chemicals in agriculture harms the soil, disrupts the ecological balance, and impacts microorganisms. Biofertilizers are gaining traction due to their eco-friendly and cost-effective benefits. This study evaluates the potential of the cyanobacterium MACC-612 (Nostoc piscinale) and plant growth-promoting bacteria (PGPB) (Azospirillum lipoferum, Pseudomonas fluorescens) in enhancing crop growth, yield, and soil health. A two-year field study was conducted using a factorial approach and a completely randomized block design, comprising four replications. The three levels of the cynobacterium (0, 0.3, or 1 g/L of N. MACC-612) and different bacteria strains were used in the experiments. The results demonstrated substantial enhancements in seed number per ear, kernel weight, and yield when using N. piscinale and PGPB, whether used individually or in combination. The soil pH, humus, (NO3 + NO2)-nitrogen, and soil microbial biomass showed significant increases across both years. The combining application of the N. piscinale (0.3 g/L) with A. lipoferum increased grain yield by 33.20% in the first year and 31.53% in the second. The humus and (NO3 + NO2)-nitrogen content significantly rose in treatments involving N. piscinale at 0.3 g/L combined with A. lipoferum at about 20.25% and 59.2%, respectively, in comparison to the untreated control. Hence, the most effective approach was the combined use of N. piscinale and A. lipoferum, which enhanced maize growth and soil fertility. Full article
