Special Issue Information

Dear Colleagues, 

This Special Issue aims to gather transdisciplinary contributions with innovative research, methodological proposals, and research ideas on sustainable cultivation/production systems.

We focus on unraveling the interactions, and designing cultivation systems, where the crop plant breeding lines are cultivated along with their rhizosphere components. In order to achieve this, we must “learn” from the rhizospheres, which have assisted landraces and crops’ wild relatives in surviving under various stress situations. We use next-generation sequencing combined with high-resolution microscopy and metabolomic approaches, as well as nanointerface studies to expand the potential of modern plant-breeding lines. Sustainable production system issues are critical in regions where the effects of climate change have created severe stress conditions (e.g., the Global South), but also in the Global North where artificial fertilization has resulted in agricultural pollution and crop nutritional stress.  

For this Special Issue, we seek the submission of regular research papers, communications, short notes, and reviews with research proposals.

Alfalfa, a crop cultivated worldwide for use as livestock feed, exhibits great adaptability to various environmental conditions. This study evaluates the biomass production, lipid peroxidation, photosynthetic pigments and osmo-compatible response in Medicago sativa var CW660 mycorrhizae (AM) and non-mycorrhizae (NM) plants with Rhizophagus intraradices and when subjected to salinity (100 mM and 200 mM of NaCl). They were evaluated using the following morphological parameters: foliage fresh weight (FFW), foliage dry weight (FDW), root fresh weight (RFW), root dry weight (RDW), foliage length (FL) and root length (RL), chlorophylls a and b, proline and malondialdehyde (MDA) in AM and NM plants treated with different concentration of NaCl. The LFW and the LDW were higher in M plants. The RFW and the RDW increased in control AM plants, and under different saline treatments there were no differences between AM and NM in either parameter. FL increased in the control and at 100 mM of NaCl in M plants. Chlorophyll a decreased 27–30% and b decreased 1–50% in AM and NM plants at 200 mM NaCl. The proline level increased four times and promoted a defense in AM plants at 200 mM of NaCl. Lipid peroxidation decreased in AM plants by 10% at maximum salinity. M. sativa CW660 is sensitive to salinity stress, and inoculation with arbuscular mycorrhizal fungi (AMF) regulates its physiology and performance under such conditions, with osmotic protection and membrane protection.

(1) Background: Soil salinity impacts plant growth and productivity in steppic regions. Thus, the current study aims at producing, at low cost, an inoculum composed of native arbuscular mycorrhizal fungi (AMF) strains adapted to saline soil management. (2) Methods: The propagation of the native AMF strains was carried out in three natural saline soils presenting increasing salinity levels (4.5, 8.5 and 9.3 dS·m−1 in Boughzoul (BG), Salt Rocket (SR) and Zaafrane (ZA) sites, respectively). Three host plant species (alfalfa, clover and leek) were tested as trap cultures. AMF spore richness and diversity, the quantification of soil microbial biomass and the determination of the most probable number (MPN) were carried out before and after 24 months culture. Moreover, the mycorrhizal rates of the host plant species were assessed. (3) Results: The moderate saline soil (SR) planted with alfalfa was found to be the most suitable for AMF inoculum production with a maximum of 650 spores, 10 g−1 of soil, a mycorrhizal rate of 86%, 70 propagules·g−1 of soil and the highest microbial biomass content. (4) Conclusion: This study points out the best combination for the production of a more adapted AMF biofertilizer for saline soil management and proposes several indicators for biofertilizer quality evaluation.

Rising atmospheric carbon dioxide (CO2) levels can impact plant photosynthesis and productivity and threaten food security, especially when combined with additional environmental stressors. This study addresses the effects of elevated CO2 in combination with low nutrient supply on Lemna minor (common duckweed). We quantified plant growth rate and nutritional quality (protein content) and evaluated whether any adverse effects of elevated CO2, low nutrients, or the combination of the two could be mitigated by plant-microbe interaction. Plants were grown under controlled conditions and were either uninoculated or inoculated with microorganisms from a local pond that supported L. minor populations. Under low nutrients in combination with high CO2, growth (plant area expansion rate) decreased and biomass accumulation increased, albeit with lower nutritional quality (lower percentage of protein per plant biomass). Inoculation with plant-associated microorganisms restored area expansion rate and further stimulated biomass accumulation while supporting a high protein-to-biomass ratio and, thus, a high nutritional quality. These findings indicate that plant-microbe interaction can support a higher nutritional quality of plant biomass under elevated atmospheric CO2 levels, an important finding for both human and non-human consumers during a time of rapid environmental change.

In recent years, the adoption of sustainable pest management strategies has increased interest in the utilization of biopesticides, with a focus on harnessing beneficial microorganisms. Among these, lipopeptides, such as surfactins, iturins, and fengycins produced by the genus Bacillus, have gained significant attention due to their multifaceted biocontrol mechanisms and wide-ranging inhibitory effects. This review aims to address the regulation, biosynthesis, and production of three main lipopeptide families secreted by the genus Bacillus, as well as the identification and quantification analysis used to date, through the omic tools approach. The three families have been identified as key contributors to the biocontrol abilities of these bacteria, with their broad-spectrum activity making them valuable tools in integrated pest management approaches that aim to reduce reliance on chemical pesticides use while maintaining crop health and productivity.
