“…The plant microbiome plays an important role in plant health and defense against plant pathogens. Plant-associated microbiota can defend against plant pathogens via direct competition, producing antimicrobial compounds or stimulating plant immunity to resist or tolerate pathogen infection [3][4][5]21]. To date, a plethora of research topics involved in the identification of microbial members in citrus associated with CLas.…”

“…Microorganisms can be associated with plants in different compartments, including the rhizosphere, rhizoplane, phyllosphere, and endosphere [1,2]. The plant microbiomes can perform a variety of functions on plants, such as supplying nutrition for plants, improving tolerance against biological and abiotic stresses through phytohormones, and producing antimicrobial compounds or stimulating plant immunity to improve disease resistance [3][4][5]. Therefore, the plant microbiome plays an important role in the plant life cycle, also considered to be an integral component of the host plant.…”

Huanglongbing (HLB), caused by the Candidatus Liberibacter spp., is the most devastating disease in the citrus industry. HLB significantly affects and alters the microbial community structure or potential function of the microbial community of leaves and roots. However, it is unknown how the microbial community structure of the pericarp with different pigments is affected by Candidatus Liberibacter asiaticus (CLas). This study identified the enriched taxa of the microbial community in the citrus pericarp with normal or abnormal pigment and determine the effects of HLB on the pericarp microbial community using 16S rRNA-seq. The alpha and beta diversity and composition of microbial communities were significantly different between normal and abnormal pigment pericarp tissues of ripe fruits infected by CLas. Firmicutes, Actinobacteriota, Bacteroidota, Acidobacteriota, and Desulfobacterota dominated the pericarp microbiota composition in WDYFs (whole dark yellow fruits) samples. The relative abundance of most genera in WDYFs was higher than 1%, such as Burkholderia, and Pelomonas. However, with the exception of the HLB pathogen, the relative abundance of most genera in the abnormal-colored pericarp samples was less than 1%. CLas decreased the relative abundance of pericarp taxonomic. The predicted function of microbial was more plentiful and functional properties in the WDYF sample, such as translation, ribosomal structure and biogenesis, amino acid transport and metabolism, energy production and conversion, and some other clusters of orthologous groups (COG) except for cell motility. The results of this study offer novel insights into understanding the composition of microbial communities of the CLas-affected citrus pericarps and contribute to the development of biological control strategies for citrus against Huanglongbing.

“…The green revolution in agricultural production has increased the use of agrochemicals (pesticides, herbicides, and fertilizers) to enhance crop productivity to meet food security is posing harmful effects on our environment [4]. Moreover, salinity, drought, and inadequate nutrients caused less production in agriculture [5]. These chemicals are also damaging the environment by adding up heavy metal residues, which ultimately enter the food chain by using contaminated food and water [6,7].…”

Growth and Yield of Okra Exposed to a Consortium of Rhizobacteria with Different Organic Carriers under Controlled and Natural Field Conditions

et al. 2022

Crop yields, soil fertility, and soil quality decline due to the overuse of chemical fertilizers and other agrochemicals. The damaging effects of these agrochemicals on the environment can be minimized by integration with eco-friendly approaches, i.e., biofertilizers. These eco-friendly biofertilizers containing plant growth-promoting rhizobacteria, (PGPR) not only solubilize mineral nutrients for crop uptake but also release phytohormones for their growth improvements. The objective of this research is to use these PGPR’s capacity to promote growth in order to increase okra production. For this purpose, different organic carriers were used, i.e., Press mud, Charcoal, Biochar, Peat, and Compost for PGPR’s inoculation. Before being used as a consortium with various carrier materials, the pre-isolated and characterized PGPR strains (AN-35, ZM-27, and ZM-63) were tested for compatibility against one another. The PGPR consortium and carriers were applied in the following treatments, i.e., T0: (control), T1: PGPR, T2: Peat + PGPR, T3: Pressmud+ PGPR, T4: Compost + PGPR, T5: Charcoal + PGPR, and T6: Biochar + PGPR in the present pot and field studies. Under the pot experiment, the results depicted that all treatments showed a significant increase in okra growth, nutrient contents, and yield of okra along with increasing the microbial biomass in the soil but the treatment containing PGPR consortium with peat caused the maximum increase. Similarly, the results of the field experiment also showed a significant increase under all treatments but the maximum increase in nutrient contents, growth attributes, and yield of okra was found under the treatment containing PGPR consortium with peat (T2). Therefore, this study recommends the use of peat and studied the PGPR consortium as a suitable carrier to develop carrier-based biofertilizers for sustainable okra production.
