Whole Genome Resequencing of Tobacco K326 and Cold-Sensitive Mutant M18

1,155,183 SNPs and 286,674 InDels were detected in wild-type tobacco K326, while its cold-sensitive mutant M18 had 1,724,339 SNPs and 360,131 InDels. This dataset, authored by Hui Yin and shared under CC-BY-4.0, contains genomic variant data from a comparative analysis aimed at identifying genes linked to cold-induced early flowering. The data was last updated on May 1, 2026.

Use Cases

• Identify candidate genes for cold stress tolerance based on SNP and InDel differences between the two genotypes
• Analyze functional enrichment of mutated genes using the provided GO classification categories like plant reproduction and kinase activity
• Investigate pathways involved in cold response using the KEGG analysis results mentioning oxidative phosphorylation and plant photosynthesis
• Study the role of specific transcription factors (MYB, WRKY) and kinases (14-3-3, MAPK, CDPK) in flowering time regulation

Strengths

• Dataset quantifies a large number of genomic variants, with over 1.1 million SNPs in the wild type and over 1.7 million in the mutant
• Analysis identifies 75 candidate genes associated with flowering and stress resistance, providing a focused target list for researchers
• Functional annotations (GO and KEGG) are provided, giving context to the potential biological impact of the detected mutations

Limitations

• The dataset is small (120.7 KB), suggesting it contains summary or processed results rather than raw sequencing reads
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale analyses
