Six chromosomal transposon mutations in Agrobacterium tumefaciens which result in an inability to synthesize cellulose fibrils were mapped to the vicinity of trp-2 and met-6. Mutations which result in an inability to attach to plant cells, attC43 and attC69, also mapped in this region, as did one Tn5 mutation which caused overproduction of cellulose. Another cellulose overproduction mutation mapped at a distance and was closely linked to ilv-13. The results suggest that there is a region of the A. tumefaciens chromosome located near met-6 which is concerned with the interaction of the bacterium with the host cell surface.
根癌农杆菌中导致无法合成纤维素微纤丝的六个染色体转座子突变被定位到trp - 2和met - 6附近。导致无法附着到植物细胞上的突变attC43和attC69也定位在该区域，一个导致纤维素过量产生的Tn5突变也是如此。另一个纤维素过量产生突变定位在远处，并且与ilv - 13紧密连锁。结果表明，在根癌农杆菌染色体上靠近met - 6的区域存在一个与细菌和宿主细胞表面相互作用有关的区域。
