“…Catalase and oxidase enzymes reduce the oxidative damage in crop while α-amylase enzyme in the aleurone layer of seed helps in hydrolyzing the endospermic starch into sugar molecules, which provide energy for vigour index parameter. [37][38][39][40][41][42][43][44] Similar results were found by Mumtaz et al 45 who reported positive results for catalase and protease activity of Bacillus strain. He also reported the cellulose degradation ability of Bacillus strains and these enzymes were comprehensively reported for their effectiveness in tolerating stress.…”

Growth promoting Rhizobium spp are frequently used as biofertilizers for agricultural cropping system. Furthermore, Isolation, screening and biochemical characterization of Rhizobium for a specific plant is necessary to examine ability of isolated bacteria to affect the growth and development of host plant in various ways. The current study was aimed to isolate plant specific rhizobacterial strains which are compatible with lentil (Lens culinaris Medik.L.) plant. 20 bacterial isolates have been isolated from root nodules of lentil from various agro ecological area and their biochemical characterization was performed by different plant growth promotion activities. The result showed that, among 20 isolates, four isolates have vigorous plant growth promoting activities. Four bacterial strains were able to solubilise phosphorous along with hormone production. Moreover, among four bacterial strains, two strongly produced HCN and siderophore in vitro. Subsequently, all selected bacterial isolates were inoculated in lentil seeds of variety HUL57 to study germination percentage and vigour index of the crop. Out of four isolates 26N isolate performed best growth promotion activities on lentil seedlings. Finally, on the basis of performance of bacteria on plant, four isolates were characterized using molecular approach of species identification such as 16S rRNA sequencing.

The application of biostimulants has been proven to be an advantageous tool and an appropriate form of management towards the effective use of natural resources, food security, and the beneficial effects on plant growth and yield. Plant-growth-promoting rhizobacteria (PGPR) are microbes connected with plant roots that can increase plant growth by different methods such as producing plant hormones and molecules to improve plant growth or providing increased mineral nutrition. They can colonize all ecological niches of roots to all stages of crop development, and they can affect plant growth and development directly by modulating plant hormone levels and enhancing nutrient acquisition such as of potassium, phosphorus, nitrogen, and essential minerals, or indirectly via reducing the inhibitory impacts of different pathogens in the forms of biocontrol parameters. Many plant-associated species such as Pseudomonas, Acinetobacter, Streptomyces, Serratia, Arthrobacter, and Rhodococcus can increase plant growth by improving plant disease resistance, synthesizing growth-stimulating plant hormones, and suppressing pathogenic microorganisms. The application of biostimulants is both an environmentally friendly practice and a promising method that can enhance the sustainability of horticultural and agricultural production systems as well as promote the quantity and quality of foods. They can also reduce the global dependence on hazardous agricultural chemicals. Science Direct, Google Scholar, Springer Link, CAB Direct, Scopus, Springer Link, Taylor and Francis, Web of Science, and Wiley Online Library were checked, and the search was conducted on all manuscript sections in accordance with the terms Acinetobacter, Arthrobacter, Enterobacter, Ochrobactrum, Pseudomonas, Rhodococcus, Serratia, Streptomyces, Biostimulants, Plant growth promoting rhizobactera, and Stenotrophomonas. The aim of this manuscript is to survey the effects of plant-growth-promoting rhizobacteria by presenting case studies and successful paradigms in various agricultural and horticultural crops.

“…Although no mature endospores were present in the females, there was evidence of a low percentage of infection in a few treatments, which might be explained by a loss of the pathogenicity of the bacterium, as it kept in the form of dried roots for a long period [ 58 ]. Pseudomonas fluorescens CHA0 is capable of significantly reducing disease severity in tomato cultivars to a higher extent than in cucumber [ 61 ]. Other strains of Bacillus sp.…”

The Fight against Plant-Parasitic Nematodes: Current Status of Bacterial and Fungal Biocontrol Agents

et al. 2022

Plant-parasitic nematodes (PPNs) are among the most notorious and underrated threats to food security and plant health worldwide, compromising crop yields and causing billions of dollars of losses annually. Chemical control strategies rely heavily on synthetic chemical nematicides to reduce PPN population densities, but their use is being progressively restricted due to environmental and human health concerns, so alternative control methods are urgently needed. Here, we review the potential of bacterial and fungal agents to suppress the most important PPNs, namely Aphelenchoides besseyi, Bursaphelenchus xylophilus, Ditylenchus dipsaci, Globodera spp., Heterodera spp., Meloidogyne spp., Nacobbus aberrans, Pratylenchus spp., Radopholus similis, Rotylenchulus reniformis, and Xiphinema index.
