Background

Sugar transporters (STs) are vital for plant growth, stress responses, and signaling.
Dendrobium catenatum, a medicinal herb, has polysaccharides as its primary active components.
Understanding STs in D. catenatum is crucial for its medicinal properties and stress resilience.

Purpose Of The Study

To comprehensively analyze sugar transporters in Dendrobium.
To investigate the role of STs in polysaccharide biosynthesis and stress response in D. catenatum.
To provide a foundation for future functional research on STs in Dendrobium.

Main Methods

Identification of MST, SUT, and SWEET gene families in four Dendrobium species.
Phylogenetic analysis, structural arrangement, regulatory network analysis, and expression profiling of STs.
Analysis of STs involved in polysaccharide biosynthesis under red-blue light treatment.

Main Results

Seven sugar transporters were identified as involved in polysaccharide biosynthesis in D. catenatum.
Red-blue light treatment effectively enhanced polysaccharide accumulation and influenced related gene expression.
Comprehensive analysis provided insights into ST evolution and function in Dendrobium.

Conclusions

This study elucidates the evolution and functional annotation of sugar transporters in Dendrobium.
It establishes a basis for future research into STs involved in polysaccharide synthesis and stress adaptation.
