| The rhizosphere soil of pulse crops | Penicillium expansum, Mucor piriformis, Botrytis cinerea | Apple | All 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 tobacco | Phytophthora nicotianae | Tobacco | P. 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 preservation | Fusarium oxysopoyum | Tomato | P. fluorescens PEF-5#18 could colonize in rhizosphere soil and extend inside tomato root-stem. | C |
| Academic exchange | Penicillium italicum | Citrus | P. 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 exchange | Colletotrichum musae | Banana | P. fluorescens FP7 was positive for the production of siderophores and DAPG. | C+M |
| Academic exchange | / | Tomato | P. fluorescens ATCC 13525 produced siderophores, and the content of iron in seeds soaked in bacterial fluid increased significantly. | C |
| Academic exchange | Pythium aphanidermatum | Turmeric plants | P. 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 potato | Streptomyces scabies | Potato | The 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 wheat | Xanthomonas | Tomato | The 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 lancea | The VOCs produced by P. fluorescens ALEB7B could promote the growth and volatile oil accumulation of Atractylodes lancea. | M |
| Laboratory preservation | Ralstonia solanacearum | Tomato | The 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. plant | Botrytis cinerea | Medicago truncatula | The 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 | / | Tobacco | Eleven different compounds were detected in VOCs from P. fluorescens, and the VOCs could promote the growth of tobacco. | M |
| Laboratory preservation | Pseudomonas syringae | Arabidopsis | P. fluorescens G20-18 could produce cytokinins and promote plant growth. | M |
| The rhizosphere soil of tomato | Meloidogyne incognita | Tomato | H2O2 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 pea | Erysiphe pisi | Pea | P. 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 | / | Blackberry | P. fluorescens N21.4 treatment caused increased expression of some flavonoid biosynthetic genes in blackberry fruits. | I |
