Abstract:

The aim of this study is to reveal the gene expression of Lilium pumilum under saline-alkali stress, and to provide a theoretical basis for rational utilization of saline-alkali land and large-scale planting of Lilium pumilum. Using the bulb of annual Lilium pumilum as material, treated with 20 mmol/L NaHCO3 for 24 h, the transcriptome was sequenced by Illumina HiSeqTM2000 sequencing platform. A total of 56828 mRNA annotation information was measured, among which 55433 Unigenes were annotated to NR database, 26973 Unigenes were annotated to KOG database, 23610 Unigenes were annotated to GO database, and 13142 Unigenes were annotated to five categories of KEGG database. 390 differentially expressed genes were identified. 9 genes closely related to saline-alkali stress were selected for qPCR verification, and the expression results of the 9 genes were basically consistent with the results of transcriptome. Through the transcriptome comparison data of Lilium pumilum under carbonate (NaHCO3) stress, many gene expression pathways and expression differences were provided, which could lay a theoretical basis for rational utilization of saline-alkali land and large-scale planting of Lilium pumilum.
