Roses, a popular ornamental crop, often face various abiotic stresses during growth and development, such as cold, drought, salinity. Rosa multiflora is commonly used rootstock exhibits strong resistance to both biotic stresses, making it an ideal material for studying mechanisms resistance. Among the largest plant families, MYB transcription factors play crucial role in stresses. Our previous research has indicated that RmMYB44 could be involved low-temperature response of R. multiflora. This study further investigated RmMYB44, revealing its expression levels were upregulated chilling, salt stress. The results suggested potential key factor Additionally, encoded nuclear-localized protein without self-activating function. overexpression tobacco plants enhanced evidenced by improved compared wild-type (WT) under conditions 4 °C, 30% water-holding capacity, 200 mM NaCl, respectively. Moreover, plants, hydrogen peroxide malondialdehyde (MDA) significantly reduced; activities superoxide dismutase (SOD), peroxidase (POD), catalase (CAT); well proline content NtPOD, NtCAT, NtCBF; elevated We assumed stress conferred was associated with regulation cell membrane integrity. aimed elucidate gene mechanism against stress, thereby providing candidate molecular breeding roses related species.
