摘要： Dendrobium catenatum is a well-known ornamental and medicinal plant producing polysaccharide as the main active ingredient. Cellulose synthase-like (Csl) genes encode glycosyltransferases that are involved in polysaccharide synthases, influencing plant growth development. However, the Csl gene family has not yet been systematically cataloged in D. catenatum. . Here, a total of 59 Csl genes were identified in D. catenatum and classified into A-J subgroups. Transcriptomic analysis revealed that nine DcCsl genes were differentially expressed in two varieties ('Green' and 'Red'). The DcCslG3b showed high expression in D. catenatum 'Green', which was positively correlated with the polysaccharide content. DcCslG3b, localized in the endoplasmic reticulum, was significantly increased in leaves or stems of D. catenatum under drought and low-temperature treatment, respectively. Co-expression network and promoter cis-element analysis indicated that the ERF2 is potential transcription factor of DcCslG3b. Furthermore, the transient expression of DcCslG3b remarkably reduced water loss rate of tobacco leaves, thus might result in drought tolerance of plants. This study will lead to a better understanding of Csl-mediated polysaccharide synthesis and abiotic stress response in D. catenatum.
