Cucumis sativus Transcriptome or Gene expression
To elucidate the molecular mechanisms underlying low-nitrogen (LN) tolerance in cucumber (Cucumis sativus L.), we performed an integrated analysis of the transcriptome (RNA-seq) and chromatin accessibility (ATAC-seq). We compared a LN-tolerant accession (C52) and a LN-sensitive accession (C13) under normal nitrogen (NN) and low nitrogen (LN) conditions. This dataset aims to decipher the hierarchical regulatory networks and identify core transcription factors (e.g., CsTGA7) driving early N-starvation adaptation. The study reveals how epigenetic changes coordinate with transcriptional reprogramming to regulate nitrogen use efficiency (NUE).
