AB  - In addition to defense response, phytohormone jasmonate participates in various 
      plant growth and developmental processes. Nonetheless, its role in the seedling 
      stage is not well defined. We recently report that jasmonate suppresses hypocotyl 
      elongation and promotes cotyledon unfolding in etiolated Arabidopsis seedlings. 
      The molecular basis underlying this phenotype is that jasmonate treatment reduces 
      the biochemical activity of CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) to stabilize 
      several COP1-targetted transcription factors for eliciting a proportion of light 
      responsive transcriptome. We further reveal that jasmonate receptor CORONATINE 
      INSENSITIVE 1 (COI1) and bHLH transcription factor MYC2 are required for the 
      suppression of COP1 activity. Because elongated hypocotyl and closed cotyledons 
      secure the success for seedling soil emergence, here we investigate seedling soil 
      emergence under jasmonate treatment and find that jasmonate reduces the seedling 
      emerging rates in the wild-type plants. Consistent with the largely insensitive 
      to jasmonate in the suppression of skotomorphogenesis, the soil emerging rates in 
      coi1 or myc2 mutants are almost not altered in the presence of jasmonate. Our 
      data addendum describe that jasmonate-triggered inhibition of etiolation growth 
      results in the defects in seedling soil emergence and suggest that 
      defense-stimulated jasmonate biosynthesis might affect seedling germination in 
      soil.
