Integrated regulatory network reveals the early salt tolerance mechanism of Populus euphratica

Abstract Salinization is one of the major factors that threaten the existence of plants worldwide. Populus euphratica has been deemed to be a promising candidate for stress response research because of its high capacity to tolerate extreme salt stress. We carried out a genome-wide transcriptome anal...
