It was typically indirect effect that the following variations induced in the progenies of endosperms implanted by heavy ion beams were discovered. 1 In comparison with control, there were very high differences in biological trait, anti-oxidation enzyme activity, MDA content and protein content, chromosome aberration rate and micro-nucleus rate in M1 generation. 2 Shorter stem variants and purple stem mutants were analyzed by RAPD and AFLP. The analytic results showed that the sequences of their DNA were changed, so those variations were not physiological damage only. And there were differences among M2 generation plants of the same sort of variants or mutants, it was indicated that M2 generation may be in disjunction.

M1代的生物学性状、幼苗的抗氧化酶活性、MDA含量、蛋白质含量和染色体畸变率及微核率等发生了较大的变化。2）对其矮杆变异株和紫色茎杆突变体（M2）做RAPD和AFLP分子鉴定等研究，结果显示了矮杆变异体和紫色茎杆突变体的DNA序列发生了改变，而非仅仅产生生理损伤；同一种变异体或突变体，在M2代单株间也存在着明显的差异，表明它们可能还处于分离状态。

Episome is an additional genetic element that can exist either as an autonomous entity or be inserted into the continuity of the chromosome of a host cell.

附加体是能插入寄生细胞连续的染色体之中，也能以自主实体而存在的一种附加遗传因素。

The cutoff value of E2/E6, used to distinguish the pure episomal form from a mixed form of episomal and integrated HPV16 DNA, was 0.81 in the multiplex real-time PCR test. c） HPV16 existed as episomes in most of the CIN Ⅰ lesions, and 42.9% of them had mixed episomal/integrated HPV16. The integrated form of HPV16 constituted the majority in most of the CIN Ⅱand CIN Ⅲ cases. In squamous cervical carcinomas, the HPV16 was mostly integrated into the host chromosome. d） The rate of HPV16 integration was associated with the degree of cervical lesions and the rate increased with the progression of cervical disease, e） The rate of pure integrated HPV16 in stage Ⅱ and Ⅲ（88%） was higher than that in stage Ⅰ（33.3%）. Conclusions: a） Multiplex real-time PCR is a rapid and sensitive method for detection of the integration state of HPV16 DNA. b） The integration of HPV16 DNA is a very early event in the development of cervical cancer and may act as an activation mechanism for progression from preinvasive to invasive cervical cancer, c） The pure integrated HPV16 in cervical cancer may be a useful prognostic indicator.

HPV—16E2、E6标准曲线相关系数均为1.00，扩增效率均在95％以上：2）确定0，81作为多重实时PCR区分游离型和混合型HPV-16的界值、3）CINⅠ中HPV—16大多以游离方式存在，但仍有整合的发生（42，9％）；CINⅡ和CINⅢ中HPV—16以混合型为主：浸润癌中以整合型HPV—16为主。4）HPV-16整合发生率与不同程度的宫颈病变有关，并且随着宫颈病变级别的升高HPV-16整合发生率呈上升趋势-5）Ⅱ＋Ⅲ期宫颈癌中整合型HPV—16所占比例显著高于Ⅰ期宫颈癌结论：1）多重实时定量PCR是一种敏感性高、简便快速的HPV—16病毒存在状态的检测方法2）HPV-16整合是宫颈癌变的早期事件，与宫颈癌前病变的进展有关。3）宫颈癌中整合型HPV—16的发生可能具有预后价值
