Arsenic accumulation in soil is a global problem typically addressed using phytoremediation methods. Pteris.vittata, a model arsenic hyperaccumulator, has great potential as a genetically engineered plant for phytoremediation..However, the lack of omic information on this species has severely limited the identification and.application of its arsenic hyperaccumulation and regulation components. In this study, we used an optimized.single-molecular real-time (SMRT) strategy to create a de novo full-length transcriptomic–tonoplast proteomic.database for this unsequenced fern and to determine the genetic components underlying its arsenic hyperaccumulation-.regulation mechanisms. We established a comprehensive network consisting of six major transporter.families, two novel resistance pathways, and a regulatory system by examining alternative splicing (AS).and long non-coding RNA (lncRNA) in different tissues following As(III) and As(V) treatment. The database and.network established in this study will deepen our understanding of the unique hyperaccumulation and regulation.mechanisms of P. vittata, ultimately providing a valuable resource for futher research on phytoremediation.of arsenic-contaminated soil.
