Trihelix transcription factors (TTFs) are light-sensitive proteins characterized by a triple-helix structure that play crucial role in regulating plant growth and development, especially response to abiotic stressors, such as drought salinity. This intriguing family of has been the focus extensive functional studies across various species. Despite their recognized significance, trihelix Populus euphratica not thoroughly explored, warranting more attention. study identifies 35 full-length genes euphratica, which grouped into five categories (GT-1, GT-γ, GT-2, SIP1, SH4) based on conserved motifs structural similarities, these unevenly distributed 19 linkage groups chromosomes. A syntenic analysis was conducted P. comparing it other The promoters contain numerous stress-responsive cis-elements, indicating potential for respond stress. RT-qPCR discovered significant induction gene salt stress, with 21 PeuTTF exhibiting distinct expression levels under conditions responsive Notably, heightened PeuTTF6, PeuTTF9, PeuTTF20 observed both roots leaves during suggesting TTF is connected plant’s conditions. Additionally, increases were noted PeuTTF2, PeuTTF31, PeuTTF32, may be convoluted These discoveries highlight improving tolerance plants. We offer new perspectives evolutionary trends variants we establish groundwork understanding properties salt-stressed drought-stressed provides opportunities advancement desert poplar agriculture have wider ramifications tree breeding techniques targeted at performance durability, particularly dry areas.

Populus euphratica is the only dominant tree species of desert riparian forest in Tarim River Basin and faces a great threat drought. Policy-based artificial water delivery projects are an effective engineering method to mitigate drought reduce degradation forests. Forest gaps have been shown be primary mode regeneration. However, little known about growth status P. various arid zone habitats, particularly light complex diverse microenvironmental alterations understory. This study quantified effects flooded areas on changes The relationships between changes, soil physicochemical properties, physiological characteristics were investigated through cross-experiment that compared whether process was existed. results revealed gap increased diversity conditions ground; floods decreased temperature by 1.94 °C while they air humidity 8.19%.
