Morphological conversion from spiralto coccoid forms occurred when HP was cultured with selenium and most of coccoid forms had fragmentary flagella and pilus; the effection of selenium to activity of urease, catalase, alkaline phosphatase is not exist or not evidence; selenium enable pET32a-vacA-E.coli BL21 which can express VacA produce yellow lipochrome, and the color become deeper with increasing of concentration of selenium; selenium can decrease expression of recombined VacA by restrain the growth of pET32a-vacA-E.coli,but can not influence activity and gene sequence of VacA; selenium can enhance the suppression effect of recombined VacA for gastric cancer cell, depress the index of cell multiplication and the forming rate of colony, decrease the number of cell in S period, increase total of cell in G period; After purified, the recombined VacA can be identified by VacA antibody.
体外实验结果表明:一定浓度的硒作用HP后,HP菌落数量随着硒浓度的增加而减少,菌落颜色由灰白色变为砖红色,溶血现象随硒浓度的增加和作用时间的延长而逐渐消失,HP的形态由弯曲形变为球形或椭圆形,鞭毛及菌毛出现脱落现象;硒对尿素酶、过氧化氢酶、碱性磷酸酶活性无影响或影响不明显;一定浓度的硒能使表达VacA的pET32a-vacA-E.coli BL21工程菌产生脂溶性砖红色色素,颜色随硒浓度增加而加深;一定浓度的硒通过抑制pET32a-vacA-E.coli BL21工程菌的生长,减少重组VacA表达量,但不影响其空泡毒活性及编码基因序列;纯化后的VacA重组蛋白可被VacA抗体识别,具有良好的抗原性。

The results indicated that the treatment of irradiation restrained the growth and differentiation of protocorm, especially to roots.The LD50 is 67.23Gy, because the protocorm is a integrate embryoids and higher tolerance was found. Ploidy analysis showed that most of aberrant seedlings go with the change of DNA and they were not euploid. When the plants trearted by irradiation, some of aberrant seedlings appeared stem forfication, and leaves appeared chlorophyll-deficient or green-white.,probably due to some genes' expression or closing.
结果表明:辐照处理对种胚原球茎的生长和分化有抑制作用,尤其是对根的抑制更为明显;由于种胚原球茎的完整性好,耐受性强,其辐照半致死剂量(LD50)为67.23Gy;流式细胞分析表明,大多数外部形态发生改变的植株其细胞内DNA的倍性发生了改变,出现相当多的非整倍体;此外,辐照产生的变异苗出现茎分叉、叶片缺绿或白绿相间等现象,可能是由于某些基因的表达与关闭引起的。

Plantlet regeneration from cotyledon of Citrullus lanatus cv. Zhangkang No. 4 was studied. The results showed that aseptic seedlings should be cultured in dark for 3d, then exposed to a photoperiod of 16/8h/d for 3d. The callus induction rate was higher in cotyledons placed facing downwards to the medium than in those facing upwards. The highest induction rate occurred in MS medium containing 6-BA (2.0mg/L), kinetin (1.0mg/L)and GA3 (1.0mg/L). The induction initiated in dark and took 7 days, while callus growth and differentiation proceeding for 7 days under 16/8h light-dark cycles. A highest rate of embryogenic callus was obtained after 3 successive subcultures.
