摘要:

温度胁迫是影响菠菜品质和产量的主要非生物胁迫之一,研究菠菜对温度胁迫响应的分子机制对菠菜抗逆育种具有重要意义。为给菠菜抗冷胁迫、热胁迫机制研究提供理论基础,以菠菜耐冷胁迫自交系D3和耐热自交系M10为试验材料,对其在冷胁迫和热胁迫下的转录组和代谢组进行了分析,以期探讨菠菜抗逆的转录和代谢机制。转录组学分析表明,在冷胁迫和热胁迫下,耐冷自交系D3和耐热自交系M10的差异基因富集最多的途径基本相同。代谢组学分析表明,冷胁迫下在基因与基因组数据库(KEGG)富集通路中共同富集在嘧啶代谢、赖氨酸降解通路中;热胁迫下在KEGG富集通路中共同富集在色氨酸代谢,甲苯降解,各种其他次生代谢物的生物合成,甘氨酸、丝氨酸、苏氨酸的代谢通路中;转录组学和代谢组学联合分析结合基因注释,确定了SpADH(sov2g036390)、SpSHMT(sov1g001130)、SpALDH-1(sov4g007150)为菠菜耐冷胁迫的候选基因,SpALDH-1(sov4g007150)、SpALDH-2(sov1g043320)、SpNPC(sov1g040610)为菠菜耐热胁迫的候选基因,其中,SpALDH-1(sov4g007150)在冷胁迫和热胁迫下都显著表达,可能是菠菜抗逆的相关调控基因。

Abstract:

Temperature stress is one of the main nonbiological stresses that affect the quality and yield of spinach.Investigating the molecular response mechanism of spinach to temperature stress is crucial for spinach stress tolerance breeding.To provide a theoretical basis for the research of the mechanism of spinach resistant to cold stress and heat stress,this study used the cold-tolerant inbred line D3 and the heat-tolerant inbred line M10 of spinach as experimental materials and analyzed their transcriptomes and metabolomes under cold and heat stress to explore the transcriptional and metabolic mechanisms underlying spinach tolerance.Transcriptomic analysis showed that the pathways in which the DEGs were the most enriched in D3 and M10 were essentially the same under cold stress and heat stress.Metabolomics analysis showed that under cold stress,they were coenriched in the pyrimidine metabolism and lysine degradation in KEGG pathways.Under heat stress,these were mainly enriched in the tryptophan metabolism,toluene degradation,biosynthesis of various other secondary metabolites,and glycine,serine and threonine metabolism in KEGG pathways.The joint transcriptomic and metabolomic analysis indicated that through data analysis and gene annotation.SpADH(sov2g036390),SpSHMT(sov1g001130)and SpALDH-1(sov4g007150)were identified as the candidate genes for cold stress tolerance in spinach.SpALDH-1(sov4g007150),SpALDH-2(sov1g043320)and SpNPC(sov1g040610)were identified as candidate genes for heat stress in spinach.Among them,SpALDH-1(sov4g007150),which may be a regulatory gene for spinach stress tolerance,was significantly expressed under both cold and heat stress.
