Comparative transcriptomic analysis reveals genes regulating the germination of morphophysiologically dormant Paris polyphylla seeds during a warm stratification.

ABSTRACT: We previously analyzed the expression of genes associated with Paris polyphylla var. yunnanensis seed maturation and dormancy release; however, we were unable to clarify the relationship between gene expression levels and these processes. To reveal the molecular mechanisms underlying P. polyphylla var. yunnanensis seed dormancy release during a warm stratification, the transcriptomes of dormant and germinating P. polyphylla var. yunnanensis seeds were separately analyzed by RNA sequencing and were also compared with the transcriptomes of stem-leaf and root tissues harvested during the seed maturation stage. The RNA sequencing of five tissues generated 234,331 unigenes, of which 10,137 (4.33%) were differentially expressed among the analyzed tissues. The 6,619 unigenes whose expression vari
