“…A number of studies have revealed the significant role of defense related enzymes like L-phenylalanine ammonia lyase, peroxidase and polyphenol oxidase in disease resistance [21,61]. In our study, greater increase in the activity of PAL, POX and PPO enzymes was observed in culture/ biofilm inoculated plants as compared to non-inoculated control as well as plants without any inoculation or fungal challenge.…”

“…Potential mechanisms include mycoparasitism, competition for nutrients, production of antifungal metabolites like hydrogen cyanide (HCN), antibiotics, siderophore and induction of plant defense mechanisms [18][19][20]. A number of studies showed higher elicitation of enzymes like L-phenylalanine ammonia lyase (PAL), peroxidase (POX) and polyphenol oxidase (PPO) in plants pretreated with rhizobial strains, which play a significant role in induction of systemic resistance against several phytopathogens [21][22][23]. Rhizobia can effectively form biofilm with common soil fungi [6].…”

Development of Mesorhizobium ciceri-Based Biofilms and Analyses of Their Antifungal and Plant Growth Promoting Activity in Chickpea Challenged by Fusarium Wilt

et al. 2016

Biofilmed biofertilizers have emerged as a new improved inoculant technology to provide efficient nutrient and pest management and sustain soil fertility. In this investigation, development of a Trichoderma viride-Mesorhizobium ciceri biofilmed inoculant was undertaken, which we hypothesized, would possess more effective biological nitrogen fixing ability and plant growth promoting properties. As a novel attempt, we selected Mesorhizobium ciceri spp. with good antifungal attributes with the assumption that such inoculants could also serve as biocontrol agents. These biofilms exhibited significant enhancement in several plant growth promoting attributes, including 13-21 % increase in seed germination, production of ammonia, IAA and more than onefold to twofold enhancement in phosphate solubilisation, when compared to their individual partners. Enhancement of 10-11 % in antifungal activity against Fusarium oxysporum f. sp. ciceri was also recorded, over the respective M. ciceri counterparts. The effect of biofilms and the M. ciceri cultures individual on growth parameters of chickpea under pathogen challenged soil illustrated that the biofilms performed at par with the M. ciceri strains for most plant biometrical and disease related attributes. Elicitation of defense related enzymes like L-phenylalanine ammonia lyase, peroxidase and polyphenol oxidase was higher in M. ciceri/biofilm treated plants as compared to uninoculated plants under pathogen challenged soil. Further work on the signalling mechanisms among the partners and their tripartite interactions with host plant is envisaged in future studies.

“…Kucuk (2013) studied interactions between pathogenic fungi and rhizobial strains on yeast glucose mineral agar (YGMA) culture medium by recording inhibition of radial fungal mycelium growth in presence or absence of rhizobia to determine the inhibitory effects of rhizobia against F. oxysporum, F. moniliforme, F. solani, and F. culmorum solid media in Petri plates by dividing them in two halves by marking with permanent marker. Rhizobium species significantly reduced wilt and root rot on common bean and chickpea caused by Fusarium species (Akhtar and Siddqui, 2007;Arfaoui et al, 2007).…”

“…Biocontrol mechanism of rhizobia may involve the production of antibiotics, HCN, siderophores and/or phytoalexins which acts against plant pathogenic microorganism.Inhibition of microbes was most likely due to expression of essential metabolites produced in excess by the interacting microorganisms in a medium where it is in limited supply (Arfaoui et al, 2007). The amount and variety of nutrients available to the interacting organisms in the soil are very different to those of culture media (Kucuk, 2013).…”

Suppression of soil-borne root pathogens of arid legumes by Sinorhizobium saheli

2015

View full text Add to dashboard Cite

The productivity of arid legumes in arid and semi-arid tracks remains virtually stagnant over decades because of their susceptibility to root diseases. The information on interaction of beneficial nitrogen fixing rhizobia with particular reference to arid legumes of the region is limited. Systematic studies on predominant species Sinorhizobium saheli in management of root pathogens in arid legumes were undertaken. In-vitro interactions of root pathogens and S. saheli isolated from arid legumes significantly suppressed the growth of all fungal pathogens in presence of S. saheli. In addition the growth of Rhizobium was stimulated in presence of different root pathogens. A field experiment on integrated disease managementexhibited that the maximum root nodulation with the maximum seed yield of 1325 kg/ha was observed from treatment where seeds were treated with S. saheli. Whereas, the minimum root nodulation was recorded in treatment, where a mixture of isolated fungal root pathogens were co-inoculated with S. Saheli was recorded from cowpea. The minimum seed yield was recorded from treatment wherein the mixture of isolated root pathogens of arid legumes was co-inoculated with S. Saheli due to increased disease pressure. The results of in-vitro and in-vivo efficacy of S. saheli strains suggest that their co-inoculation with PGPR's can not only reduce the use of chemical fertilizers but also can significantly enhance yields by increasing plant growth and suppressing soil borne plant pathogenic fungi.
