- Abstract
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 AtRecQl s 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.
