马铃薯地上及地下匍匐茎的转录组分析
Transcriptome Analysis of Aerial and Underground Stolons in Potato
摘要
Abstract
To reveal the transcriptomic differences between above-ground and below-ground stolons of potato and their associated developmental regulatory mechanisms,this study conducted transcriptome sequencing a-nalysis on above-ground(M9-UP)and below-ground(M9-DOWN)stolons using the homozygous potato line M9 as experimental material.A total of 1 243 differentially expressed genes(DEGs)were identified through differential expression analysis,with the overall gene expression level in above-ground stolons being higher than that in below-ground stolons.GO enrichment analysis showed that DEGs in above-ground stolons were mainly enriched in biological processes such as photosynthesis and light capture,while those in below-ground stolons were enriched in starch biosynthesis,phenylpropane metabolism,and other processes.KEGG enrich-ment analysis indicated that above-ground stolons were significantly enriched in pathways such as photosyn-thesis-antenna proteins and carbon fixation,whereas below-ground stolons were mainly associated with starch synthesis and secondary metabolite biosynthesis.The results of this study provide a theoretical basis for eluci-dating the specialized developmental mechanism of potato stolons and the prevention and control of the"stolon escaping"phenomenon.关键词
