摘要

螺旋酶几乎参与了所有核酸代谢过程。在这个家族中,RecQ螺旋酶蛋白通过DNA重组、修复和复制保护所有生物体基因组的完整性。本研究重点研究了拟南芥中具有不同功能的五个类 RecQ(AtRecQl)基因。在无性和生殖发育阶段对 ProAtRecQl:GUS 表达的分析显示了器官和组织的特异性模式。AtRecQls转录水平在非生物胁迫下的变化表明它们参与了多种刺激反应。值得注意的是,在各种盐浓度和低温条件下,atrecql2 和 atrecql3 突变体的发芽率和生长率都较低。这些发现表明,AtRecQl2和AtRecQl3在发芽和发芽后阶段是非生物胁迫耐受性的正调控因子。

Expression patterns of Arabidopsis thaliana RecQ-like (AtRecQl) genes and the roles of AtRecQl2 and AtRecQl3 in response to abiotic stress.

Helicases are involved in almost every nucleic acid metabolism process. Within this family, RecQ helicase proteins protect genome integrity across all organisms through DNA recombination, repair, and replication. This study focused on five Arabidopsis thaliana RecQ-like (AtRecQl) genes with diverse functionalities. Analysis of ProAtRecQl: GUS expression during vegetative and reproductive development stages revealed organ- and tissue-specific patterns. Changes in AtRecQls transcript levels in response to abiotic stressors suggest their involvement in diverse stimuli responses. Notably, germination and growth rates were lower in atrecql2 and atrecql3 mutants under various salt concentrations and cold conditions. These findings indicate that AtRecQl2 and AtRecQl3 act as positive regulators of abiotic stress tolerance during the germinative and postgerminative phases.
