谷胱甘肽过氧物的基因表示(ATGPX3 ) 3 用 ATGPX3 promoter-glucuronidase (GUS ) 在 Arabidopsis 响应渗透的应力被分析转基因的植物。GUS 表示的 Highlevels 在 ATGPX3 promoter-GUS 在渗透的应力下面被检测转基因的植物。与野类型相比, ATGPX3 异种(atgpx3-1 ) 的生长和发展对甘露糖醇更敏感。另外,在 atgpx3-1was 的 RD29A, ABI1, ABI2 和 RbohD 的表示由骆驼毛的织物应力导致了。这些结果建议 ATGPX3 可能涉及渗透的应力的 signaltransduction。
Gene expression of glutathione peroxidase 3 (ATGPX3) in response to osmotic stress was analyzed in Arabidopsis using ATGPX3 promoter-glucuronidase (GUS) transgenic plants. High levels of GUS expression were detected under osmotic stress in ATGPX3 promoter-GUS transgenic plants. Compared with the wild type, the growth and development of ATGPX3 mutants (atgpx3-1) were more sensitive to mannitol. In addition, the expression of RD29A, ABI1, ABI2 and RbohD in atgpx3-1 was induced by ABA stress. These results suggest that ATGPX3 might be involved in the signal transduction of osmotic stress.
