Abstract
Soil salinization has seriously affected plant growth and restricted economic development. Malus zumi is an excellent apple grafting rootstock, and it is also an important tree species to improve saline-alkali land. Under the stress of 200 mM NaCl, the yellowing of Malus zumi leaves became more obvious with time, the activities of antioxidant enzymes increased, and the chlorophyll content increased first and then decreased. Through transcriptome sequencing analysis, 426 new genes were found in a total of 37191 transcriptome sequences, and these new genes were still different from those of apple. After 48 hours of salt stress, compared with the untreated group, 4861 genes were differentially up-regulated and 4413 genes were differentially down-regulated. Through GO function enrichment analysis and pathway function enrichment analysis, it was found that salt stress affected the amino acid synthesis, metabolism, photosynthesis, and other related processes of Malus zumi. Analysis of differential transcription factors revealed that WRKY and ERF families were the important transcription factors involved in salt stress. The gene located at the key positions of metabolic pathway was verified by fluorescence quantitative PCR, and the results were consistent with the results of transcriptome sequencing, which proved the reliability of the data of differentially expressed genes.
