Studies on mechanisms of Pseudomonas fluorescens on biocontrol

SourcesPathogenHostControl methodsMechanism
The rhizosphere soil of pulse cropsPenicillium expansum, Mucor piriformis, Botrytis cinereaAppleAll three isolates produced protease, siderophores and VOCs, and could colonize the wounds of apples. In addition, isolate 2-28 was positive for the HCN biosynthesis gene, and both isolate 1-112 and 4-6 were positive for the gene encoding the production of PCA.P+C+M
The rhizosphere soil of tobaccoPhytophthora nicotianaeTobaccoP. fluorescens P-72-10 produced protease, cellulose, siderophores and VOCs. Also, it effectively reduced MDA content and increased POD, PPO, PAL, CHI and GLU activity in tobacco seedlings.P+C+M+I
Laboratory preservationFusarium oxysopoyumTomatoP. fluorescens PEF-5#18 could colonize in rhizosphere soil and extend inside tomato root-stem.C
Academic exchangePenicillium italicumCitrusP. fluorescens could inhibit spore germination, germ tube elongation and mycelial expansion of P. italicum, and rapidly grow in the wound of fruits, thus improving the CHI and GLU activities of citrus fruits.C+I
Academic exchangeColletotrichum musaeBananaP. fluorescens FP7 was positive for the production of siderophores and DAPG.C+M
Academic exchange/TomatoP. fluorescens ATCC 13525 produced siderophores, and the content of iron in seeds soaked in bacterial fluid increased significantly.C
Academic exchangePythium aphanidermatumTurmeric plantsP. fluorescens FP7 was positive for the biosynthesis gene of PCA, DAPG, Plt, Prn and HCN. In addition, the activities of defense enzymes such as POD, PPO, PAL and SOD were enhanced by a combination of rhizome dip and soil drench of FP7 liquid formulation treatment.M+I
The rhizosphere soil of potatoStreptomyces scabiesPotatoThe isogenic mutant of LBUM223 (phzC–), not producing PCA, was incapable to reduce S. scabies growth. PCA produced by P. fluorescens LBUM223 reduced S. scabies thaxtomin A production, leading to reduced virulence.M
The rhizosphere soil of wheatXanthomonasTomatoThe tailocins produced by P. fluorescens SF4c caused damage to the cell envelope of strain Xanthomonas, resulting in a rapid leakage of intracellular materials.M
Atractylodes lancea/Atracty– lodes lanceaThe VOCs produced by P. fluorescens ALEB7B could promote the growth and volatile oil accumulation of Atractylodes lancea.M
Laboratory preservationRalstonia solanacearumTomatoThe VOCs produced by P. fluorescens WR-1 significantly inhibited the virulence of R. solanacearum via affecting protein metabolism.M
The rhizosphere soil of Medicago spp. plantBotrytis cinereaMedicago truncatulaThe VOCs produced by all P. fluorescens strains showed a high degree of antagonism against B. cinerea during confrontation assays, and significantly increased Medicago truncatula biomass and chlorophyll content.C+M
Laboratory preservation/TobaccoEleven different compounds were detected in VOCs from P. fluorescens, and the VOCs could promote the growth of tobacco.M
Laboratory preservationPseudomonas syringaeArabidopsisP. fluorescens G20-18 could produce cytokinins and promote plant growth.M
The rhizosphere soil of tomatoMeloidogyne incognitaTomatoH2O2 biosynthesis related gene RBOH1, POD gene Ep5C expression and lignin biosynthesis related genes Tpx1 expression of the samples treated by P. fluorescens Sneb825 reached the maximum level.I
The rhizosphere soil of peaErysiphe pisiPeaP. fluorescens OKC could stimulate transcript accumulations of the Gα1 and Gα2 subunits of the heterotrimeric G protein, POD activities and phenol content in pea during the infection by E. pisi.I
The rhizosphere soil of tobacco/BlackberryP. fluorescens N21.4 treatment caused increased expression of some flavonoid biosynthetic genes in blackberry fruits.I
