摘要

结果：在干旱胁迫下，2558份基因材料在根和3691份基因材料的地上部组织中的表达与对照相比有显著差异。同样，在盐度胁迫下，根中的9078个基因材料和地上部组织中的5785个基因材料在胁迫和非胁迫条件下被区分。此外，差异表达基因的转录调控活性主要是由于激素、光、昼夜节律和应激反应性顺式作用调控元件，其中ABRE、ERE、P-box、TATC-box、CGTCA基序、GARE基序、TGACG基序、GAG基序和GA基序、GATAmotif、TCT基序、GT1基序、Box4、G-box、I-box、LAMP元件、Sp1、MBS、TC富集重复序列，TCA元素和HSE是已鉴定的上调基因中最重要的元素。

Investigation of Drought and Salinity Tolerance Related Genes and their Regulatory Mechanisms in Arabidopsis (Arabidopsis thaliana)

Results: Under drought stress, 2558 gene accessions in root and 3691 in shoot tissues had significantly differential expression with respect to control condition. Likewise, under salinity stress 9078 gene accessions in root and 5785 in shoot tissues were discriminated between stressed and non-stressed conditions. Furthermore, the transcription regulatory activity of differentially expressed genes was mainly due to hormone, light, circadian and stress responsive cis-acting regulatory elements among which ABRE, ERE, P-box, TATC-box, CGTCA-motif, GARE-motif, TGACG-motif, GAG-motif, GA-motif, GATAmotif, TCT-motif, GT1-motif, Box 4, G-Box, I-box, LAMP-element, Sp1, MBS, TC-rich repeats, TCA-element and HSE were the most important elements in the identified up-regulated genes.
