荒漠

For cloning antifreeze protein gene from a desert darkling beetle Microdera punctipenis dzunarica in Xinjiang, the primers were designed according to the core sequence of AFP gene deposited in GenBank, and the cDNA fragment about 294 bp named as MpAFP5 was amplified with the RT-PCR and 3'-RACE technique. Sequence analysis revealed that the cloned cDNA fragment named as MpAFP5 coded the mature peptide of AFP.

根据GenBank中已发表的昆虫抗冻蛋白基因的保守序列设计引物，利用RT-PCR技术结合3'-RACE扩增的方法，从新疆荒漠昆虫准噶尔小胸鳖甲Microdera punctipenis dzunarica中获得了长约294 bp不含信号肽的抗冻蛋白cDNA片段，命名为MpAFP5，其全长序列为363 bp(GenBank注册号为：AY821792)。

This text first from desert, desertification, concept appraised to desertification start with, explain the desertificated purpose and meaning further, desertification purpose lying in explaining why the land is desertificated, desertificated course and desertificated development degree and speed appraised, the fragility of the natural environment, and the reason that the land depredate.
