Abstract
Iris domestica is a popular gardening plant. Although the species is considered tolerant to drought, its growth and development are often affected by drought conditions. Therefore, revealing the regulatory mechanisms of drought tolerance in this species will aid in its cultivation and molecular breeding. In this study, morpho-physiological and transcriptome analyses of the roots of I. domestica plants were performed under persistent drought conditions. Peroxidase activity, proline content, and tectoridin content increased under sustained drought conditions. Transcriptome analysis showed that the roots of I. domestica seedlings respond to drought mainly by regulating the expression of drought-resistant genes and biosynthesis of secondary metabolites. This study provides basic data for identifying drought response mechanisms in Iris domestica.
