Siderophore and chitinase producing isolates from the rhizosphere of Nicotiana glauca Graham enhance growth and induce systemic resistance in Solanum lycopersicum L.
The rhizobacterial strains produced siderophore and suppressed the growth of Fusarium species a fungal phyto- pathogen.
The activity of PGPR against plant pathogens has been reported to be through competition for nutrients, siderophore medicated competition for iron, or antibiosis [4], or indirectly through induce systemic resistance in plants against pathogens [25].
The members of phylum Proteobacteria are well known for their role in agriculture possesses several plant growth promoting mechanisms including: phytohormones polyamine siderophore production phosphate solubilization (Perrig et al.
In addition to fixing atmospheric N, the bacteria of bio-fertilizer of nitroxin helps to the growth and development of roots and shoots of plants by provoking the exudation of growth stimulators like the kinds hormones of growth regulators such as auxin, and also production different amino acids and various kinds of antibiotics, hydrogen cyanide and siderophore.
The four strains were related to the phylogenetic group B2 and produced the iutA (ferric aerobactin receptor), YuA (Yersinia siderophore receptor), and film (type 1 fimbriae) virulence lactors (8).
It was found that the bacterial isolates which showed siderophore production also exhibited higher antifungal activity.
The siderophore, staphyloferrin A, removes iron from both human and porcine [ILLEGIBLE TEXT] thus, the metal can be available to invading cells in humans and in hogs.
In addition to genes related to ribosome, citrate cycle (TCA cycle), and energy production, what prominent is that 5 genes related to siderophore biosynthesis were also activated in PA0861 mutant (Table 2), which seems to be in consistency with the GO analysis result (Fig.
