Bacillus amyloliquefaciens yog cov kab mob uas muaj txiaj ntsig zoo hauv cov kab mob Gram-positive koom nrog hauv kev tawm tsam cov kab mob hauv av los ntawm kev tso tawm ntawm cov metabolites theem nrab thiab muaj peev xwm rhizosphere siab.Biofilm tsim yog suav tias yog qhov yuav tsum tau ua ua ntej rau kev muaj peev xwm rhizosphere siab.Hauv kev ua haujlwm no, peb pom tias cov nroj tsuag rho tawm cuam tshuam rau chemotaxis thiab biofilm tsim ntawm B. amyloliquefaciens SQY 162 (SQY 162).Tag nrho cov carbohydrates kuaj tau ua rau chemotaxis thiab biofilm tsim ntawm SQY 162 hom;Txawm li cas los xij, cov kab mob loj hlob tsis tau cuam tshuam los ntawm kev ntxiv cov carbohydrates.Cov lus teb muaj zog chemotactic thiab biofilm tsim ntawm SQY 162 ob leeg raug ntxias los ntawm pectin los ntawm kev txhawb nqa ntawm surfactin synthesis thiab transcriptional qhia ntawm biofilm tsim muaj feem xyuam nrog cov noob caj noob ces.Cov txiaj ntsig no tau qhia tias pectin tuaj yeem ua haujlwm ib puag ncig hauv kev txhawb nqa ntawm biofilm tsim ntawm SQY 162. Tsis tas li ntawd, nyob rau hauv lub lauj kaub thwmsim cov surfactin ntau lawm thiab cov populat ion ntawm SQY 162 nyob rau hauv lub rhizosphere ho nce nrog ntxiv ntawm sucrose los yog pectin, whereas cov abundance ntawm cov kab mob pathogen Ralstonia txo.Nrog rau kev tsim cov metabolites theem nrab hauv rhizosphere ntawm luam yeeb los ntawm SQY 162 thiab txhim kho colonization ceev ntawm SQY 162 hauv kev kho pectin, cov kab mob tshwm sim ntawm cov kab mob wilt tau zoo suppressed.Txoj kev tshawb fawb tam sim no tau qhia tias qee cov nroj tsuag rho tawm tuaj yeem ua lub zog los yog ib puag ncig cues rau SQY 162 txhawm rau txhim kho cov pej xeem ceev ntawm cov hauv paus luam yeeb thiab bio-tswj kev ua tau zoo ntawm cov kab mob wilt.
