The demand for and industrial production of P. yunnanensis is an important traditional Chinese medicinal herbaceous species in the family Melanthiaceae. However, the seeds of most medicinal plants undergo seed dormancy, which slows plant growth. Seed dormancy is an important adaptive trait that helps plants respond to unflavoured environments. polyphylla synthesized more bioactive 13-H GA (GA 4) to break its seed dormancy. Through inhibition the expression of genes related to the synthesis of 13-OH GAs and up-regulation genes related to the synthesis of 13-H GAs, P. The conversion of ABA to ABA-GE catalysed by UGTs may be the main cause of ABA degradation. These results suggest that PLA2 mediated production of lysoPLs may correlate to the seed dormancy breaking of P. The expression of CYP707As was not synchronous with the change of ABA content, and the expression of most UGTs, GA20ox and GA3ox up-regulated during seed dormancy breaking. polyphylla seeds dormancy breaking, 13-OH GAs, such as GA 53 were not detected, and GA 3 decreased significantly, whereas 13-H GAs, such as GA 15, GA 24 and GA 4 increased. Changes of different GAs varied during P. Abscisic acid (ABA) decreased dramatically during seed dormancy breaking of P. The expression of phospholipase A2 ( PLA2), genes correlated to the production of lysoPLs, up-regulated significantly during this process. Widely targeted metabolomics revealed that lysophospholipids (lysoPLs) increased during P. In this study, we investigate the global metabolic and transcriptomic profiles of Paris polyphylla during seed dormancy breaking.

Paris polyphylla is an important Chinese herbaceous species, and the dormancy trait of its seed limits the cultivation of this herb. Among these factors, membrane lipids and plant hormones are two of the most important ones. The disruption of seed dormancy is a complicated process and is controlled by various factors.
