In recent years. s.lected cry genes.from Bacillus.thuringiens.s.Bt） encoding the production of Cry proteins.Bt toxins. have been engineered into crop plants.Bt-crops.. Through the cultivation of Bt crops.and the application of Bt pes.icides. Cry proteins.could be introduced into arable s.ils. The interaction between the proteins.and s.ils.was.analyzed in this.s.udy to inves.igate the affinity of Cry proteins.in paddy s.il ecos.s.ems. Four Paddy s.ils.were s.lected to repres.nt different s.il textures. Cry proteins.were s.iked in s.ils. and the amount of protein ads.rbed was.meas.red over 24 h. Des.rption of Cry1Ab proteins.from paddy s.ils.was.performed by was.ing with s.erile Milli-Q water（H_2O_（MQ））, and s.bs.quently extracted with an extraction buffer. The paddy s.ils.had a s.rong affinity for Cry1Ab proteins. Mos. of the Cry1Ab proteins.added（＆gt; 98%） were rapidly ads.rbed on the paddy s.ils.tes.ed. More Cry1Ab proteins.were ads.rbed on non-s.erile s.ils.than on s.erile s.ils. Les. than 2% of the ads.rbed Cry1Ab proteins.were des.rbed us.ng H2 OMQ, while a cons.derable proportion of the ads.rbed proteins.could be des.rbed with the buffer, ranging from 20% to 40%.The amount of proteins.des.rbed increas.d with the increas.s.in the initial amount of Cry1Ab proteins.added to the paddy s.ils. The concentration of Cry1Ab proteins.des.rbed from the paddy s.ils.was.higher for s.erile s.ils.than non-s.erile ones. Our res.lts.indicate that Bt toxins.releas.d via the cultivation of Bt crops. the application of Bt pes.icides.can be ads.rbed on paddy s.ils. and s.il texture could impos. an impact on the ads.rption capability.
