摘要

低温等离子体(LTP)对种子萌发和作物生长有良好的影响。应用LTP对桔梗种子萌发进行了研究,研究了其萌发指标、生理参数和转录组特征。结果表明:与对照相比,LTP处理下桔梗种子发芽率和萌发势分别提高了24.7%和30.7% (p < 0.05);种子芽的SOD和CAT活性分别比对照提高了26.78%和12.41%。转录组结果显示,在LTP和CK, 14342个不同表达基因(DEGs)上调,4366个下调。本研究发现了相当数量的与植物激素信号转导、过氧化物酶体、氧化磷酸化、淀粉和蔗糖对低温血浆的响应有关的deg。转录组基因表达谱为研究桔梗种子低温等离子体萌发的分子机制提供了有价值的基因组工具。为桔梗的栽培种植提供理论依据和实践指导。

New insights of low-temperature plasma effects on seeds germination of Platycodon grandiflorum
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.
