Transcriptome analysis of Populus × canadensis 'Zhongliao1' in response to low temperature stress.

ABSTRACT:

Background

Low temperatures are known to limit the growth and geographical distribution of poplars. Although some transcriptomic studies have been conducted to explore the response of poplar leaves to cold stress, only a few have comprehensively analyzed the effects of low temperature on the transcriptome of poplars and identified genes related to cold stress response and repair of freeze-thaw injury.

Results

We exposed the Euramerican poplar Zhongliao1 to low temperatures; after stems were exposed to - 40℃, 4℃, and 20℃, the mixture of phloem and cambium was collected for transcriptome sequencing and bioinformatics analysis. A total of 29,060 genes were detected, including 28,739 known genes and 321 novel genes. Several differentially expressed genes (n = 36) were found to b
