Low temperature plasma (LTP) exerted beneficial effects on seed germination and crop growth. With application of LTP on seed germination of Platycodon grandiflorum, germination indexes and physiological parameters and transcriptome profile were investigated in this experiment. The results showed the seed germination rate and germinating potential of Platycodon grandiflorum in LTP increased by 24.7% and 30.7% comparing to CK respectively (p < 0.05). The SOD and CAT activity of the seed sprouts increased by 26.78% and 12.41% comparing to CK. Transcriptome results showed that 14342 up-regulated and 4366 down-regulated different expressing genes (DEGs) at LTP and CK. A considerable number of DEGs related to the plant hormone signal transduction, peroxisome, oxidative phosphorylation, starch and surose in response to low temperature plasma were identified in this study. The transcriptomic gene expression profiles present a valuable genomic tool to the molecular mechanisms of Platycodon grandiflorum seed germination underlying low temperature plasma. which can provide theoretical basis and practical guidance for cultivation and planting of Platycodon grandiflorum.
