Rice is a crucial crop for many people worldwide, especially in regions like Asia, Latin America, and parts of Africa. Thailand is one of the largest exporters of rice. Nowadays, farmers use chemicals to control rice disease, which can have negative effects on humans and the environment. Therefore, the objective of this study was to examine the plant-promoting capabilities of the endophytic fungal strains DMKU-R3G3 in greenhouse settings. The endophytic fungi strain DMKU-R3G3, which was isolated from organic rice root, was identified as Aspergillus cejpii based on morphological characteristics and phylogenetic analysis. The production of IAA was detected using Salkowski’s reagent. After 7 days of incubation, the finding revealed that the strain cultivated in PDB supplemented with tryptophan yielded a greater concentration of IAA (25.45 μg/mL). The inoculation with A. cejpii DMKU-R3G3 significantly enhanced rice growth, as evidenced by notable increases in shoot height, root length, and fresh weight. Moreover, the chlorophyll content of the rice plants also increased by 1.78 times more than the control group. In addition, proteomic analysis revealed that rice responded toward the colonization of endophytic fungi by producing auxin-responsive proteins to regulate the IAA content in plant tissue and inducing total chlorophyll production due to the up-regulation of proteins in the chlorophyll biosynthesis pathway. The results obtained from this study lead to the conclusion that the A. cejpii strain DMKU-R3G3 possesses the capability to enhance plant growth through the production of phytohormones in greenhouse conditions. Therefore, endophytic A. cejpii DMKU-R3G3 has the potential to be a promising eco-friendly plant growth promoter for sustainable rice cultivation.

“…However, identifying appropriate strains of potential biocontrol agents and characterizing associated metabolites remains a complex and arduous task [21][22][23]. To address this issue, bioinformatics tools such as genome mining for biosynthetic genes can be used to rapidly predict the secondary metabolites produced by a BCA strain [22][23][24]. Thus, the identification of genetic blueprints is essential for recognizing bioactive secondary metabolites and enzymes that mediate most biocontrol mechanisms [22].…”

Bacillus strain PE1, which was isolated from potatoes harvested in the Yaqui Valley, Mexico, was evaluated as a potential biological control agent against Fusarium languescens. The draft genome sequence was obtained through Illumina NovaSeq sequencing, revealing a genomic size of 4,071,293 bp, with a G + C content of 44.13%, an N50 value of 357,305 bp, and 27 contigs. The taxonomic affiliation was confirmed by analyzing the 16S rRNA gene and overall genome relatedness indices (OGRIs) and constructing a phylogenomic tree based on the whole genome, which showed a close relationship to Bacillus cabrialesii subsp. cabrialesii. Genomic annotation using RAST and Prokka identified 4261 coding DNA sequences (CDSs) distributed across 331 subsystems, highlighting genes associated with biocontrol, stress response, and iron acquisition. AntiSMASH 7.1 was used for genome mining, revealing seven biosynthetic gene clusters that potentially produce biocontrol-related metabolites. In vitro assays confirmed the antagonistic activity of strain PE1 against Fusarium languescens CE2, demonstrating its potential to inhibit mycelial growth. The study provides a genomic basis for investigating B. cabrialesii subsp. cabrialesii PE1 as a potential biological control agent in potato production.

“…In other words, a growing demand for agricultural products has been observed, while the amount of cultivated land, the soil structure, and availability of natural resources has been steadily decreasing [ 5 , 6 , 7 , 8 ]. Thus, global agriculture’s capacity will no longer be able to sustain the increasing demand of nutriment supply without compromising environmental integrity and human health.…”

Halobacteria-Based Biofertilizers: A Promising Alternative for Enhancing Soil Fertility and Crop Productivity under Biotic and Abiotic Stresses—A Review

et al. 2023

View full text Add to dashboard Cite

Abiotic and biotic stresses such as salt stress and fungal infections significantly affect plant growth and productivity, leading to reduced crop yield. Traditional methods of managing stress factors, such as developing resistant varieties, chemical fertilizers, and pesticides, have shown limited success in the presence of combined biotic and abiotic stress factors. Halotolerant bacteria found in saline environments have potential as plant promoters under stressful conditions. These microorganisms produce bioactive molecules and plant growth regulators, making them a promising agent for enhancing soil fertility, improving plant resistance to adversities, and increasing crop production. This review highlights the capability of plant-growth-promoting halobacteria (PGPH) to stimulate plant growth in non-saline conditions, strengthen plant tolerance and resistance to biotic and abiotic stressors, and sustain soil fertility. The major attempted points are: (i) the various abiotic and biotic challenges that limit agriculture sustainability and food safety, (ii) the mechanisms employed by PGPH to promote plant tolerance and resistance to both biotic and abiotic stressors, (iii) the important role played by PGPH in the recovery and remediation of agricultural affected soils, and (iv) the concerns and limitations of using PGHB as an innovative approach to boost crop production and food security.
