The purpose of this study was to explore the role of SND1 (secondary wall associated NAC domain protein1, SND1), a fiberspecific NAC transcription factor, on the growth and abiotic stress of Chrysanthemum lavandulifolium. In this study, ClSND1like gene was cloned from C. lavandulifolium and its bioinformatics, subcellular localization and expression pattern analysis were performed. The results showed as follow: (1) the full length of ClSND1like gene CDS is 1 185 bp, encoding 395 amino acids, which are unstable hydrophobic amino acids and more closely related to pyrethrum gene. (2) The results of subcellular localization showed that the ClSND1like gene was not expressed in leaves, but was specifically expressed in the duct wall of stem, which was a lignin specific gene. (3) Realtime quantitative PCR results showed that the expression level of ClSND1like gene was the highest in stem, and very low in root and leaf, and the expression level gradually increased with the aging of stem. The expression levels were significantly increased in osmotic stress and salt stress. These results suggest that the ClSND1like gene may be related to lignin formation, and may be involved in regulating plant growth and salt and osmotic stress. This study lays a foundation for the study of both growth and abiotic stress resistance of ClSND1like gene in C. lavandulifolium, and also provides a new idea for the study of growth and resistance of Chrysanthemum plants.
