Potato (Solanum tuberosum L.) is recognized globally as the most significant non-cereal staple crop. Leaf senescence, which significantly impacts tuber yield, serves as a critical indicator of potato maturity. Despite its importance, the molecular mechanisms regulating this process remain largely unknown. In a previous study, we grafted the early-maturing variety 'Zhongshu 5' (Z5) onto the late-maturing variety 'Zhongshu 18' (Z18), and demonstrated that the rootstock's leaves displayed physiological characteristics suggestive of early senescence. Here, we analyzed the transcriptome data of the Z5 and Z18 grafts to conduct weighted gene co-expression network and gene expression clustering analysis. Differentially expressed genes in cluster 9, as well as the floralwhite module, exhibited markedly elevated expression levels during the onset of leaf senescence. These genes were found to be enriched in several senescence related processes, such as chloroplast organization, electron transport chain, and chlorophyll metabolic process. Furthermore, we constructed transcription factor correlation networks and hub gene co-expression networks. By monitoring the expression patterns of these genes throughout the whole growth period, we identified two candidate genes, StWRKY70 and StNAP, which may play pivotal roles in leaf senescence. This study contributes valuable genetic resources for further investigations into the regulatory mechanism governing potato leaf senescence, with implications for genetic improvements, particularly in terms of maturity and yield.
