Full-length transcriptome analysis of maize root tips reveals the molecular mechanism of cold stress during the seedling stage.

ABSTRACT:

Background

As maize originated in tropical or subtropical zones, most maize germplasm is extremely sensitive to low temperatures during the seedling stage. Clarifying the molecular mechanism of cold acclimation would facilitate the breeding of cold tolerant maize varieties, which is one of the major sustainability factors for crop production. To meet this goal, we investigated two maize inbred lines with contrasting levels of cold tolerance at the seedling stage (IL85, a cold tolerant line; B73, a cold sensitive line), and performed full-length transcriptome sequencing on the root tips of seedlings before and after 24 h of cold treatment.

Results

We identified 152,263 transcripts, including 20,993 novel transcripts, and determined per-transcript expression levels. A total of
