In a diluted synthetic medium solidified by 0.17% agar populations of Agrobacterium spread with a velocity of 0 to 20 mm/24 hours. This spreading is a consequence of chemotactic movement and cell division. Different bacterial strains spread with a characteristic velocity each. Loss of the TI-plasmid leaves the spreading behaviour unimpaired. It is changed after the introduction of virulence by Kerr transfer or after prolonged culture in D-amino acids.
在由0.17%琼脂固化的稀释合成培养基中，农杆菌群体以0至20毫米/24小时的速度扩散。这种扩散是趋化运动和细胞分裂的结果。不同的细菌菌株各自以特定的速度扩散。TI质粒的缺失并不影响其扩散行为。在通过克尔转移引入毒力后或在D-氨基酸中长时间培养后，扩散行为会发生改变。
