Transcriptome Sequencing Analysis of Pistia stratiotes under Combined Nanoplastic and Cadmium Stress
This study used Pistia stratiotes as the experimental material and conducted transcriptomic sequencing analysis under combined nanoplastic and cadmium stress, aiming to systematically reveal the molecular response characteristics and adaptive mechanisms of P. stratiotes to complex pollution stress. By analyzing differentially expressed genes and their enriched pathways, the study focused on clarifying the effects of combined stress on photosynthesis, antioxidant defense, metabolism, signal transduction, and stress adaptation-related processes in P. stratiotes. It further sought to elucidate the regulatory network underlying plant stress responses under the combined action of nanoplastics and cadmium, thereby providing a theoretical basis for understanding the physiological and molecular mechanisms by which aquatic plants respond to emerging complex pollutants.
