Screening and Preliminary Identification of Asparagus officinalis Varieties under Low-Temperature Stress

To meet the large demand for in the spring market and improve the economic benefits of cultivating asparagus, we explored the molecular mechanism underlying the response of to low temperature. First, "Fengdao No. 1" was screened out under low-temperature treatment. Then, the transcriptome sequencing and hormone detection of "Fengdao No. 1" and "Grande" (control) were performed. Transcriptome sequencing resulted in screening out key candidate genes, while hormone analysis indicated that ABA was important for the response to low temperature. The combined analysis indicated that the gene may regulate ABA in under low temperature. And the phylogenetic tree was constructed, and subcellular localisation was performed. From these results, we speculated that the gene may regulate ABA in . The results of this research provide a theoretical basis for the further exploration of low-temperature response in .
