“…Consequently, plants have superior sanity with improved growth and development (GUPTA et al, 2015;XU et al, 2016). Hernández et al (2018) For the other cultivars, the use of the products did not result in a significant increase in production. Possibly, the other cultivars were less adapted to the region and/or had lower genetic performance in relation to production, so that the application of Bacillus-based products could not contribute significantly to the increase in fruit mass production.…”

Oneof the factors that can compromise the strawberry culture is theuse of seedlings without phytosanitary quality. The aim of this study was to evaluate the use of three biological products in the production of strawberry cultivars. For this, six cultivars ('Camino Real', 'Festival', 'Oso Grande', 'Albion', 'San Andreas'and 'Camarosa') were selected to receive the following treatments: T1) Onix (2.4 mL) + Qualit (0.6 mL) (Bacillus methylotrophicus+ Trichoderma asperellum); T2) Rhizos (2.4 mL) + Qualit (0.6 mL) (Bacillus subtilis+ Trichoderma asperellum) and T3) Control. After the production cycle, the total production (g kg-1), estimated average production (kg ha-1) and number of fruits in each plot were evaluated. 'Festival' and 'Oso Grande' were the most productive cultivars and their greatest yields were observed in the presence of Bacilluscompared to control. Plants grown in the presence of B. methylotrophicusand B. subtilisshowed a higher number of fruits. The use of these biological products is important for strawberry cultivation.

“…Similar results were observed by Erdogan et al [100], who reported that the inoculation of Bacillus and Pseudomonas promoted a significant increase in leaf surface in grapevines, and by Rodrigues et al [101] after inoculation of sugarcane with isolates of Enterobacter, Pantoea, and Klebsiella. In strawberries, an increase in the number and surface of leaflets and roots was observed after inoculation with Bacillus methylotrophicus isolate M4-96 [42]. Increasing the leaf surface is especially interesting because it has a direct link with the light harvested by the plants and, consequently, photosynthesis.…”

“…The sequencing of the 16S rDNA gene allowed the identification of taxa known to include PGPB. Bacteria belonging to the genera Bacillus [38,39,42,100,104], Enterobacter [73,82,101] and Paenibacillus [72,81] have been described as PGPB, including in straw-berry [44], with the ability to fix nitrogen asymbiotically, as well as to produce auxins and solubilize phosphate. Surprisingly, MET12M2, which showed the greatest potential for promoting growth in strawberry plants, belongs to the genus Brevibacillus.…”

“…[39] demonstrated the effect of a wide variety of microorganisms with different physiological and biochemical capacities. In addition, some studies have shown efficient growth promotion of strawberry plants after inoculation with PGPB [38][39][40][41][42][43][44]. New research work testing the inoculation of PGPBs in strawberries can add important information about the potential use and benefit of new efficient bacterial strains.…”

The Friend Within: Endophytic Bacteria as a Tool for Sustainability in Strawberry Crops

Strawberry (Fragaria x ananassa, Duch.) is an important crop worldwide. However, since it is a highly demanding crop in terms of the chemical conditions of the substrate, a large part of strawberry production implies the application of large amounts of fertilizers in the production fields. This practice can cause environmental problems, in addition to increases in the fruit’s production costs. In this context, applying plant growth-promoting bacteria in production fields can be an essential strategy, especially thanks to their ability to stimulate plant growth via different mechanisms. Therefore, this study aimed to test in vitro and in vivo the potential of bacteria isolated from strawberry leaves and roots to directly promote plant growth. The isolates were tested in vitro for their ability to produce auxins, solubilize phosphate and fix nitrogen. Isolates selected in vitro were tested on strawberry plants to promote plant growth and increase the accumulation of nitrogen and phosphorus in the leaves. The tested isolates showed an effect on plant growth according to biometric parameters. Among the tested isolates, more expressive results for the studied variables were observed with the inoculation of the isolate MET12M2, belonging to the species Brevibacillus fluminis. In general, bacterial inoculation induced strain-dependent effects on strawberry growth. In vitro and in vivo assays showed the potential use of the B. fluminis MET12M2 isolate as a growth promoter for strawberries.

“…Bacillus spp. may directly raise plant yield via mechanisms that impart the production of phytohormones or plant growth regulators, such gibberellins, auxins, and ethylene (Park et al 2017;Shahzad et al 2017;Vicente et al 2019). Additionally, this study revealed that rice yields of plants with B. subtilis JN005 treatments (524.40 ± 17.88) g/ m 2 were higher than the water control (340.55 ± 12.55) g/ m 2 and fungicide B. subtilis WP (488.15 ± 13.69) g/m 2 treatments.…”

It is quite important to develop the microorganism resources with biocontrol capacity for rice blast. This study evaluated Bacillus subtilis JN005 for growth promotion and biocontrol efficacy against Magnaporthe oryzae. Results showed that rice seeds treated with 1 × 107 cfu/mL suspension of B. subtilis JN005 had 16% germination energy, 14% germination rate, 15% germination index, and 270% vigor index compared to those treated with sterile water (control). In pot experiments, the JN005 strain-treated rice plants exhibited notable increase in plant height, root length, stem circumference, and fresh weight, as well as higher concentration of chlorophyll a, chlorophyll b, and total chlorophyll in rice leaves. Rice leaves inoculated with the JN005 strain resulted in increased activities of defense-related enzymes, including peroxidase (POD), phenylalanine ammonialyase (PAL), superoxide dismutase (SOD), and catalase (CAT) compared to the water and the M. oryzae-inoculated treatments. In vitro inoculated rice leaves with 1 × 107 cfu/mL bacterial suspension compared to sterile water or control treatment exhibited lower disease incidence in the curative and preventive groups by 79% and 76%, respectively. Field experiment showed that after spraying with 1 × 107 cfu/mL bacterial suspension, efficacy rates on controlling rice blast on plants were (56.82 ± 1.12)% and (58.39 ± 3.05)% at seedling and maturity stages, respectively, and that rice production yield was (524.40 ± 17.88) g/m2. Therefore, B. subtilis JN005 could be a promising biological control agent for rice blast, thereby warranting further investigation of its efficacy.
