Ectopic expression of potato ARP1 encoding auxin-repressed protein confers salinity stress tolerance in Arabidopsis thaliana.

ABSTRACT: Salinity stress is one of the most detrimental factors affecting crop production worldwide. Genetic engineering offers a promising approach for improving agronomic traits and enhancing stress tolerance. In a previous work, several potential candidate genes were identified in potato using large-scale functional yeast screening. In this work, we characterized one of the identified genes, an auxin-repressed protein 1 (ARP1), in transgenic Arabidopsis plants. ARP1 transgenic lines were subjected to salinity stress and compared with wild-type (WT) plants. Compared to WT plants, transgenic ARP1 lines showed significant improvements in morphological parameters, such as plant height, leaves per plant, root length, and fresh weight. Additionally, biochemical and physiological analyses revealed that
