Abstract:

To explore the cold-tolerant mechanisms of lavender(Lavandula angustifolia Mill.),transcriptomics methods were used for discovering and analyzing the molecular regulation networks in responses to cold treatments in this research. The CBF-COR regulation networks composed by CBF transcription factors and their target genes COR played significant roles in improving plant cold-tolerance. In this research,seven CBF genes(LaCBF)and 11 COR genes(LaCOR)were found with significant expression difference under cold stress. Meanwhile,four upstream genes including LaICE1LaCAMTA3LaEBF1,and LaCCA1 in CBF regulation pathways were found to be responsive to cold stress. It is considered that the cold signal regulation networks together formed by these genes took the key roles in resistance to low temperature in Lavandula angustifolia.

Key words: Lavandula angustifolia, low temperature stress, transcriptomics analysis, CBF transcription factors
