“…These microorganisms increased the foliar uptake of phosphorus levels in Trifolium repens (white clover) plants, which stimulated the production of biomass and mycorrhizal colonization compared with the inoculation of each individual organism. According to Ramasamy et al (2011), plant growth-promoting rhizobacteria, such as actinomycetes, could positively influence the development of mycorrhizal symbiosis through different mechanisms of action. In this regard, Carpenter-Boggs et al (1995) found 19 actinomycetes capable of stimulating in vitro germination of G. margarita by producing volatile compounds that could benefit the plant in terms of greater growth.…”

To evaluate the inoculation effect of Arbuscular Mycorrhizal Fungi (AMF) and actinomycetes on promoting plant growth and diminishing wilt in pepper plant (Capsicum annuum L.), a pot experiment was conducted under greenhouse conditions using a factorial design on random blocks. It was evaluated the native Cerro del Metate mycorrhizal consortium, and ABV39 and ABV02 actinomycetes were evaluated against the CH11 stain of Phytophthora capsici. Responses of the variables evaluated were plant height, stem diameter, number of leaves, total fresh and dry biomass, leaf area and radical volume, number of AMF spores, mycorrhizal colonization, roots infected with P. capsici, and severity of wilting utilizing an ordinal qualitative scale. The results showed that mycorrhizal plants and inoculated with ABV39 demonstrated the highest values for plant height, stem diameter, and number of leaves with 26.12 cm, 5.29 mm, and 35.12 leaves, respectively. Co-inoculation of AMF and both actinomycetes significantly promoted (p≤0.001) total fresh and dry biomass and leaf area of the plants without P. capsici. The disease severity of the AMF-inoculated plants diminished against plants without mycorrhization. However, when they were also co-inoculated with ABV39 or ABV02, disease severity was significantly reduced (p≤0.05), up to level 2 of 5 levels on a severity scale. These results show a synergetic effect with co-inoculation of AMF and actinomycetes in vegetal growth promotion and bioprotection against wilting caused by P. capsici in pepper plants.

“…While mycorrhizae transport phosphorus throughout the soil, it may not be available to the host plant without the P-solubilizing activity of certain rhizobacteria; thus, both symbionts play important roles. Fungi may facilitate colonization of the host by rhizobia and fluorescent pseudomonads (Bianciotto et al 1996), and some bacteria may improve spore colonization in turn (Ramasamy et al 2011). In addition, VAM improve rhizobial nodulation and nitrogen fixation (Table 2).…”

“…Phosphorus-solubilizing bacteria, including representatives of Rhizobium, Pseudomonas, Bacillus, and Burkholderia, increase the availability of soil P to the host plant (Barka et al 2006;Hayat et al 2010;Ramasamy et al 2011). This is often achieved by releasing organic acids, such as the 2-ketoglutonic acid produced by Rhizobium meliloti, to dissolve mineral phosphates (Halder and Chakrabartty 1993;Hayat et al 2010).…”

“…Bacteria that produce the compound 1-aminocyclopropane-1-carboxylate (ACC) deaminase can increase resistance to environmental stress such as salinity or drought by modifying ethylene levels (Hayat et al 2010). ACC deaminase hydrolyzes the ethylene precursor ACC to ammonium and α-ketobutyrate, lowering ACC and therefore ethylene levels in the plant (Ramasamy et al 2011;Glick 2012;Ahemad and Kibret 2013).…”

Beneficial microorganisms for soybean (Glycine max (L.) Merr), with a focus on low root-zone temperatures

Background Heightened interest in biologically-based methods of raising crop yields has driven research into beneficial microorganisms that can be used to improve crop growth and productivity. Scope This review addresses the potential of rhizobia, vesicular-arbuscular mycorrhizae (VAM), and plantgrowth-promoting rhizobacteria to improve growth of soybean (Glycine max (L.) Merr) under temperate conditions. Mechanisms of action of beneficial microorganisms and considerations for utilization at all root-zone temperatures (RZTs) are reviewed. Subsequent sections address current knowledge on the inhibition of soybean growth at low RZTs and the potential of beneficial microorganisms to alleviate low temperature stress. Conclusions The three categories of beneficial microorganisms discussed differ in their modes of action and have shown potential for additive or synergistic growth promotion of soybean at all RZTs. At low RZT, pot and field studies have identified strains of rhizobia and PGPR, as well as certain phytohormones, that ameliorate the inhibitory effects of cold stress on soybean growth through a variety of mechanisms. Wider use of these treatments could aid the expansion of soybean cultivation in cold climates.

BACKGROUNDMicrobial biofertilizers and algae‐based biostimulants have been recognized for supporting sustainable agriculture. Field experiments were conducted in 2022 and 2023 growing seasons in an organic farm located in Ferrara (Italy) with the aim of evaluating plant growth‐promoting microorganisms (PGPMs) and algae‐based biostimulants (Biost) in tomato (Solanum lycopersicum L.). The experimental treatments were: (i) two microbial biofertilizers (PGPM_1, PGPM_2) and no inoculated plants (No_PGPM); and (ii) two algae‐based biostimulant rates (0.5% (Biost_0.5%), 1.0% (Biost_1.0%)) and no application (No_Biost). PGPMs were applied at transplanting, while biostimulants at 15 and 30 days after transplanting. Treatments were replicated three times according to a split‐plot experimental design. Plant characteristics were evaluated at 30 days after transplanting in No_Biost treatments. During tomato cultivation, soil plant analysis development (SPAD), nitrogen difference vegetation index (NDVI), leaf area index (LAI) and photosynthetic photon flux density (PPFD) were monitored. Tomato yield was determined.RESULTSPGPM_2 showed the highest shoot biomass (132.9 g plant−1), plant height (44.7 cm), leaf number (34.0 plant−1) and root biomass (9.22 g plant−1). Intermediate values were observed in PGPM_1, while all parameters were lower in No_PGPM. Both PGPMs achieved higher values of SPAD, NDVI, PPFD and LAI than No_PGPM. Biost_1.0% increased all measured growth parameters followed by Biost_0.5% and No_Biost, respectively. Tomato yield was the highest for PGPM_2–Biost_1.0% (67.2 t ha−1). PGPMs affected fruit size and sugar content, while biostimulants were associated with color and lycopene.CONCLUSIONThe application of microbial biofertilizers and algae‐based biostimulants could be part of environment‐friendly practice in organic farming. © 2024 The Author(s).
