A 21-bp insertion in the 5' UTR of CsSnAK1 is linked to inhibited lateral branch development in cultivated cucumber by increasing CsSnAK1 mRNA abundance.
- Why it matters: Domestication breeding needs functional links between genetic variants and traits, but precise, large-scale phenotyping is difficult. Transcriptome-wide detection of variant-associated alternative splicing offers a high-throughput route to candidate genes.
- What they did: Full-length transcripts from eight developmental-stage tissues of wild and cultivated cucumber were assembled using PacBio Iso-seq and Illumina RNA-seq. Across the dataset, 6,980 genes showed alternative splicing, with ~66% of events cultivar-specific and enriched for genetic variants.
- The result: Integrating transcript structure with variant annotation highlighted cis-acting variants, including the 21-bp CsSnAK1 5' UTR insertion. This enables identification of novel functional alleles underlying domestication traits in cucumber.
