Tn7 luxCDABE marker system was successfully transferred into Pseudomonas chlororaphis (strain PL9)by means of transformation and conjugation and a stable lux marked strain PL9L was obtained.The colonizing dynamics and distribution of the luminescent bacteria PL9L in the rhizosphere of cotton planted in pots and rhizoboxes were studied by the methods of X ray film imaging and enumeration of luminescent colonies on agar media,The results of pot culture experiment showed that PL9L successfully colonized in the rhizosphere of cotton.In pot cultures of sterile soil the highest colonizing level(3 1×10 2 cfu/g root soil)was reached on 6th day after seeds sown;On 56th day,the population of PL9L tended to stable and decreased to 1 7×10 9 cfu/g root soil)but in pot cultures of unsterile soil, the highest cdonizing leovel(1 1×10 9 cfu/g root soil) was reached on 8th day.On 46th day,the population of PL9L tended to a stationary state,the numbers of them were 1 4×10 2 cfu/g root soil.The results of rhizobox culture experiment showed that PL9L spread from seeds toward the dirction of root tip,but not synchronized with the stretch of roots.6 days after seeds sown, in rhizobox culture of sterile soil,PL9L spread 12 0cm below seeds,but in non sterile soil was 11 0cm.In the region of cotton root tip,PL9L were not detected.

采用细菌转化和杂交的方法,成功地将全套发光酶基因标记系统Tn7luxCDABE引入绿针假单胞菌(Pseudomonaschlororaphis)PL9,得到稳定的发光标记菌PL9L。采用发光菌落平板计数法和X射线胶片自显影法,通过盆栽试验和盒裁试验,研究了发光标记菌PL9L在棉花根圈的定殖动态和分布规律。盆栽试验结果表明,在灭菌土盆栽中,播种后6d左右PL9L在棉花根圈的定殖水平达最高(31×109cfu/g根土),播种后56d左右趋向稳定,PL9L数量为17×102cfu/g根土;未灭菌土盆载中,播种后8d左右PL9L的定殖水平达最高(11×109cfu/g根土),46d左右趋向稳定,菌数为14×102cfu/g根土。盒栽试验结果表明,PL9L可从种子向根尖方向扩散,但并不与根的伸长生长同步,播种后36d,灭菌土盒栽中PL9L可扩散至种子下方120cm以内,而未灭菌土盒栽中PL9L扩散至110cm以内。在棉花根尖区域均未检测到PL9L。

Being inoculated on wheat seed, the colonizing dynamics and distribution of the luminescent bacteria AS 1.867-L and 3-PHB-L in the rhizosphere of wheat plant in rhizoboxes were studied by the method of X-ray film imaging and enumeration of luminescent colonies on agar media.

In rhizoboxes of sterile soil the AS 1.867-L and 3-PHB-L strains reached the highest level 9.67×10 6 and 6.90×10 6cfu/g root respectively, after 7 days with initial inoculant dose of 2.32×10 8 cfu/g root. Their population trended towards stable and decreased to 4.93×10 3 and 4.47×10 3cfu/g root respectively after 16 days. On the contrary, in rhizoboxes of unsterile soil, the highest colonizing level was 1.41×10 5 and 7.71×10 5cfu/g root respectively after 7 days. On the 16 thday, their population trended towards stationary phase and reduced to 2.27×10 4 and 5.30×10 5cfu/g root. On the 16 thday, only AS 1.867-L (1.87×10 3cfu/g root) was tested from 8cm to 16cm under the seed, while the other marked strains were little.
