Sexual Differences in Physiological and Transcriptional Responses to Salinity Stress of Salix linearistipularis.

ABSTRACT: Willow (Salix), a dioecious plant, is an important ornamental tree species in the world. Salix linearistipularis, a perennial woody plant species naturally distributed on the Songnen Plain saline-alkali land in northeast China, has a high saline condition. To study the sexual differences of S. linearistipularis in salinity tolerance, the physiological and transcriptional responses to salinity were compared between female and male cuttings. Under salinity stress, the female leaves exhibited higher superoxide dismutase and peroxidase activities and photosynthetic capacity, and lower H₂O₂ contents than those of male leaves. Under salinity stress, sodium (Na⁺) accumulation in female leaves was lower than that in the male leaves. The non-inv
