Abstract

Abstract: Chinese kiwifruit （Actinidia chinensis） ‘Qihong' and delicious kiwifruit （Actinidia deliciosa） ‘Xuxiang' with different cold tolerance were used as materials.Samples were taken during the overwintering period and analyzed for physiological parameters, and it was found that ‘Qihong' was more tolerant to low temperatures than ‘Xuxiang'. The transcriptomes of the two varieties were analyzed and the GO clusters showed greater differences in cellular components organization or biogenesis, organelle fraction, etc;KEGG clusters differed more in membrane transport, translation, transcription, replication and repair. The enrichment analysis of the 2 varieties showed differential expression of starch and sucrose metabolism, phytohormone signaling, biosynthesis of phenylpropanoids and biosynthesis of flavonoids pathways. The changes in transcript levels of the two varieties during the overwintering period were analyzed.

Key words: chinese kiwifruit （Actinidia chinensis）, delicious kiwifruit （Actinidia deliciosa）, low temperature stress, overwintering period, transcriptome
