Results indicated that the water contents in wheat leaves of uncontinuous drought treatments did not largely changed, but that of roots obviously decreased; the relative water contents in wheat leaves and roots of 24 h continuous treatments were both decreased obviously.

结果表明，每天间断干旱1~4 h处理的小麦叶片相对含水量变化较小，而根系相对含水量变化较大；连续干旱24 h后叶片和根的相对含水量均显著下降。

The minimum accumulation occurred at 96 h, at which transcripts were only 0.07 fold of that in uredinisopore. During incompatible interaction between Pst and wheat, PsCdc2 was down-regulated and its accumulation was lower than that in urediniospore.

在非亲和组合中，该基因表达基本呈下调趋势，在接种后各个时间点的表达量均低于在夏孢子中的表达量，其中接种后12 h时表达量最高，但仅为夏孢子中表达量的0.34倍；接种后96 h表达量最低，为夏孢子中表达量的0.02倍。

Secondly, the genomic DNA is extracted from Zostera marina L. and then amplified by PCR with two oligonucleotide primers synthesized to obtain the partial nucleotide sequences of the Na~+/H~+ antiporter gene. The Na~+/H~+ antiporter gene clone was obtained after a series of manipulation: purificatioin of PCR product, ligation and transformation of recombinant plasmids, blue-white selection and so on. DNA sequence analysis shows that its DNA sequence is highly homologous with the genomic DNA sequence of E.

其次，通过提取大叶藻基因组DNA，根据设计的简并性引物进行PCR扩增，纯化PCR产物，连接，重组质粒转化，蓝白斑筛选等操作，并测序，提交测定序列到NCBI进行BLASTN，结果表明：该序列与大肠杆菌的基因组序列相似性较高，而与其它物种的Na~+/H~+逆向转运蛋白基因没有相似性。
