ABSTRACT Prey attraction is an integral component of the carnivorous syndrome, yet its molecular adaptations have remained largely unexplored. Our study utilized tissue‐specific transcriptomic data from South American marsh pitcher plant, Heliamphora tatei , to explore and developmental basis prey attraction. Carnivorous plants often present specialized structures associated with in that function carried out by nectar spoon, a colorful extension top densely covered nectaries. Through comparisons gene expression spoon rest pitcher, we identified suite differentially expressed genes likely contribute attraction, including enzymes involved volatile synthesis sugar transporters. We found one lineage transporters, 14a clade SWEET s (Sugars Will Eventually Be Exported Transporters), highly upregulated has evolved more rapidly Sarraceniaceae, consistent specialization for transport as part Among related production, several best known their role floral scent. These results suggest that, similar digestion, ancient are repurposed novel functions during transition carnivory may facilitate repeated convergent origins across angiosperms.

The basic helix-loop-helix (bHLH) transcription factors play important physiological functions in the processes of plant growth, development, and response to abiotic stresses. However, a comprehensive genome-scale study ginger bHLH gene family has not been documented. In this study, 142 ZobHLH genes were identified genome. Using Arabidopsis proteins as reference, classified into 15 subfamilies unevenly distributed on 11 chromosomes ginger. Sequence characterization, multiple sequence alignment, phylogenetic analysis, conserved protein motifs exon-intron distribution patterns conducted further analyze evolutionary relationships among these proteins. results duplicated event analysis demonstrated that pivotal role segment duplication promoting expansion family. Additionally, cis-regulatory elements well interaction networks indicated potential involvement growth adversity stress. RNA-seq RT-qPCR showed ZobHLH083 ZobHLH108 key roles salt stress waterlogging stress, respectively. we systematically analyzed characteristics ginger, discovering critical rhizome present provides theoretical foundation for research ZobHLHs will help explore functional properties genes.
