“…UOM SAR 14 offered an impressive 71% protection under greenhouse and 75% protection under field conditions in spite of the heavy inoculum pressure, which was highly significant in comparison with the control and other isolates. Similar results were reported where P. fluorescens isolates have induced resistance in various host crops against various diseases such as Fusarium wilt of carnation and cucumber, grey mould of bean, sheath blight of rice, red rot of sugarcane, root rot of cucumber, Pythium aphanidermatum in tomato, Fusarium wilt and Alternaria blight in Arabidopsis and anthracnose in bean (van Peer et al, 1991, Liu et al, 1995, de Meyer and Hofte, 1997, Vidhyasekaran and Muthamilan, 1999, Viswanathan and Samiyappan, 1999, Chen et al, 1999, Ramamoorthy et al, 1999, Peiterse, 2001, Ton et al, 2002, Bigirimana and Hofte, 2002. The isolate UOM SAR 14 was unique in that, apart from showing the highest capacity of growth promotion, it was also the best inducer of resistance against downy mildew disease, and its performance in terms of growth enhancement and resistance induction was consistent both under greenhouse and field conditions during all the trials conducted.…”

“…Most reported strains of PGPR are from Pseudomonas spp., particularly Pseudomonas fluorescens strains. These can enhance plant growth and protect the plants from various plant pathogens in several crops such as cucumber, radish, tomato, sugar cane, and rice (Liu et al, 1995, Leeman et al, 1995, Raupach et al, 1996, Viswanathan and Samiyappan, 1999, Burdman et al, 2000, Ongena et al, 2000, Ramamoorthy et al, 2001. The aim of the present study was to evaluate some selected Pseudomonas fluorescens isolates for their ability to promote growth of pearl millet plants and to induce resistance against downy mildew of pearl millet.…”

Abstract. Biopriming pearl millet seeds with Pseudomonas fluorescens isolates resulted in improved growth of the plants and also induction of resistance against downy mildew disease caused by the fungus Sclerospora graminicola. Although all of the test isolates reduced disease severity and promoted growth both under greenhouse and field conditions, high variability was observed in their efficiency. Treatment due to Pseudomonas fluorescens resulted in enhancement of: germination, seedling vigour, plant height, leaf area, tillering capacity, seed weight (measured for 1000 seeds) and yield. The time required for flowering was advanced by 5 days. Isolate UOM SAR 14 registered higher levels of vegetative and reproductive growth; most importantly there was a 22% increase in grain yield. The isolates also effectively induced resistances against downy mildew disease both under greenhouse and field conditions. The isolates offered protection ranging from 20 to 75%. However, the level of disease control was less than that achieved by the systemic fungicide Apron. UOM SAR 14 offered 71 and 75% and remained consistent under all test conditions. Further studies showed that the resistance induced was systemic, required a minimum of 3 days to build up, and was sustained throughout the plant's life.

“…The type of bacterized plant response induced after challenge with a pathogen resulted in the formation of structural barriers, such as thickened cell wall papillae due to the deposition of callose and the accumulation of phenolic compounds at the site of pathogen attack (13, 14, 109). Biochemical or physiological changes in plants (139) include induced accumulation of pathogenesis-related proteins (PR proteins) such as PR-1, PR-2, chitinases, and some peroxidases (76,100,109,126,139,182). However, certain PGPB do not induce PR proteins (73,132,139,180) but rather increase accumulation of peroxidase, phenylalanine ammonia lyase, phytoalexins, polyphenol oxidase, and/or chalcone synthase (25, 120,139,178).…”

3Pathogenic microorganisms affecting plant health are a major and chronic threat to food production and ecosystem stability worldwide. As agricultural production intensified over the past few decades, producers became more and more dependent on agrochemicals as a relatively reliable method of crop protection helping with economic stability of their operations. However, increasing use of chemical inputs causes several negative effects, i.e., development of pathogen resistance to the applied agents and their nontarget environmental impacts (44, 62). Furthermore, the growing cost of pesticides, particularly in less-affluent regions of the world, and consumer demand for pesticide-free food has led to a search for substitutes for these products. There are also a number of fastidious diseases for which chemical solutions are few, ineffective, or nonexistent (62). Biological control is thus being considered as an alternative or a supplemental way of reducing the use of chemicals in agriculture (44,62,136,188).There has been a large body of literature describing potential uses of plant associated bacteria as agents stimulating plant growth and managing soil and plant health (reviewed in references 63, 70, 143, 165, and 188). Plant growth-promoting bacteria (PGPB) (8) are associated with many, if not all, plant species and are commonly present in many environments. The most widely studied group of PGPB are plant growth-promoting rhizobacteria (PGPR) (82) colonizing the root surfaces and the closely adhering soil interface, the rhizosphere (82, 84). As reviewed by Kloepper et al. (84) or, more recently, by Gray and Smith (65), some of these PGPR can also enter root interior and establish endophytic populations. Many of them are able to transcend the endodermis barrier, crossing from the root cortex to the vascular system, and subsequently thrive as endophytes in stem, leaves, tubers, and other organs (10, 28,65,70). The extent of endophytic colonization of host plant organs and tissues reflects the ability of bacteria to selectively adapt to these specific ecological niches (65, 70). Consequently, intimate associations between bacteria and host plants can be formed (28, 70, 84) without harming the plant (70,83,84,92,191). Although, it is generally assumed that many bacterial endophyte communities are the product of a colonizing process initiated in the root zone (102, 165, 177, 188), they may also originate from other source than the rhizosphere, such as the phyllosphere, the anthosphere, or the spermosphere (70).Despite their different ecological niches, free-living rhizobacteria and endophytic bacteria use some of the same mechanisms to promote plant growth and control phytopathogens (15, 46,63,70,92,165). The widely recognized mechanisms of biocontrol mediated by PGPB are competition for an ecological niche or a substrate, production of inhibitory allelochemicals, and induction of systemic resistance (ISR) in host plants to a broad spectrum of pathogens (15,63,66,67,97,146) and/or abiotic stresses (reviewed in referen...

“…The induction of systemic resistance by rhizobacteria is referred to as ISR. In recent years, the use of PGPR as an inducer of systemic resistance in crop plants against different pathogens has been demonstrated under field conditions (Wei et al, 1991;1996;Vidhyasekaran and Muthamilan, 1999;Viswanathan and Samiyappan, 1999). Nie et al(2002) reported that antibiotic-secreting plant growth-promoting bacterial strains can inhibit the proliferation and subsequent invasion of phytopathogens, hence protecting plants from further damage in the presence of arsenate.…”

Heavy metal pollution of soil is a significant environmental problem and has its negative impact on human health and agriculture. Rhizosphere, as an important interface of soil and plant, plays a significant role in phytoremediation of contaminated soil by heavy metals, in which, microbial populations are known to affect heavy metal mobility and availability to the plant through release of chelating agents, acidification, phosphate solubilization and redox changes, and therefore, have potential to enhance phytoremediation processes. Phytoremediation strategies with appropriate heavy metal-adapted rhizobacteria have received more and more attention. This article paper reviews some recent advances in effect and significance of rhizobacteria in phytoremediation of heavy metal contaminated soils. There is also a need to improve our understanding of the mechanisms involved in the transfer and mobilization of heavy metals by rhizobacteria and to conduct research on the selection of microbial isolates from rhizosphere of plants growing on heavy metal contaminated soils for specific restoration programmes.
