Gene Details:

  • Gene ID:
  • Gene Symbol: WS1
  • Gene Name: WOX-SPINE1
  • Genome:
  • Species: Lactuca serriola

Functional Descriptions:

  • A gene encoding WUSCHEL-related homeobox transcription factor, named as WOX-SPINE1 (WS1), was identified as the candidate gene controlling the spine development in lettuce, and its function on spines was verified.
  • A CACTA transposon was found to be inserted into the first exon of the WS1 allele, knocking out its function and leading to the lack of spines in cultivated lettuce.
  • All lettuce cultivars investigated have the nonfunctional WS1 gene, and a selection sweep was found at the WS1 locus, suggesting its important role in lettuce domestication.
  • The expression levels of WS1 were associated with the density of spines among different accessions of wild lettuce. At least two independent loss-of-function mutations in the WS1 gene caused the loss of spines in wild lettuce.
