The cDNA document of ACC oxidase gene of Citrus aurantium L. was cloned. By using the program of BLAST on NCBI GenBank database, the sequence presented a very high match with the ACC oxidase genes from other plants. The base sequence was analysed by using biology programe of DNAStar 5.0. 278 amino acids were coded by the base sequence and the base sequence had the same conserve region of ACC oxidase gene of many kinds of other plants. The base sequences comparability was more than 72% compared with those of many kinds of other plants. The amino acid sequences comparability was more than 70% compared with those of a lot of other plants.

克隆了酸橙1-氨基环丙烷－1-羟酸氧化酶基因cDNA片段，将片段序列在NCBI网站上进行同源性搜索，显示的皆为不同植物的ACC氧化酶基因，因而认为所克隆的片段就是酸橙ACC氧化酶基因；并运用DNAStar5.0软件进行序列分析，推导的氨基酸序列为278个残基；具有所有植物ACC氧化酶基因共有的保守区域；与多种植物的ACC氧化酶基因的核苷酸和氨基酸序列的同源性都在72%和70%以上。

Then the combinant plasmid was conducted into ACC-2 cell by electroporation. ACC-2 cells stably expressing CD was obtained by 10-day positive selection with 400 μg/mL G418. Total RNA was extracted and the expression of the CD gene in transfected ACC-2 cells was identified by RT-PCR. RESULTS: PCR yielded a fragment of l280bp and CD was verified by sequence analysis.

测序正确后，将其亚克隆到质粒表达载体pIRES中，构建以内部核糖体进入位点相连的CD基因的质粒表达载体pIRES-CD，采用电穿孔法，以质粒表达载体转染ACC-2细胞，用400μg/mL的G418筛选10d，获得稳定表达CD基因的ACC-2细胞系，提取该细胞的总RNA，用RT-PCR检测CD基因的表达。

Huang-hua' pear fruit was a typical climacteric fruit after harvest, and the fruit senescence-related factors, such as LOX activity, 02" content, AOS activity, ACC synthase activity, ACC content, ACC oxidase activity and ethylene production, changed with peaks at 20 "C. The activities of LOX, AOS, ACC synthase, ACC oxidase and the accumulation of O2 ", ACC content and ethylene synthesis were inhibited when stored at 1癈. And the severity of flesh floss and fruit decay was lightened. Low temperature combined with polyethylene film bag packing (PEF1 and PEF2) could further decrease the rate of weight loss, flesh floss, and fruit decay and keep preferable freshness. When PEF1 and PEF2 packing fruits were transferred to shelf life at 20 "C after storage at 1癈. The activities of LOX, AOS, ACC synthase, ACC oxidase could be suppressed and the accumulation of 02 , ACC content and ethylene production were slowed down to a certain extent, especially during the shelf life after 60 d storage. PEF1 and PEF2 packing fruit could maintain higher firmness as well, and the effects became more distinct along with the storage period, there existed no significant difference between PEF1 and PEF2 treatments.

试验结果表明，在20℃下，LOX活性、O2-水平、AOS活性、ACC合成酶活性、ACC含量、ACC氧化酶活性及乙烯的生成，均呈峰形变化；1℃处理可抑制LOX、AOS、ACC合成酶、ACC氧化酶的活性和O2-、ACC的积累，抑制贮藏果实的乙烯合成，减轻果肉发绵和果实腐烂。1℃下贮藏的果实，若结合不同聚乙烯薄膜袋(PEF1和PEF2)小包装，可以进一步降低果肉发绵率和果实腐烂率，保持果实新鲜度；当果实经过一段时间贮藏后，转移到20℃下，在货架期间，PEF1和PEF2对果实成熟衰老各个相关因子均有不同程度的抑制效应，主要表现在贮藏60d后的货架期间，同时维持较高的果实硬度，对硬度的影响随着贮藏时间的延长愈加明显，PEF1和PEF2处理效果之间无显著差异。
