Identification of TPS and TPP gene families in Cannabis sativa and their expression under abiotic stresses

Trehalose is a nonreducing disaccharide that involved in the regulation of plant responses to variety environmental stresses. 6-phosphate synthase (TPS) and trehalose phosphatase (TPP) are two key enzymes synthesis they widely distributed higher plants. At present, TPS family genes have been systematically identified analyzed many species, but TPP rarely studied. In this study, ten six cannabis (Cannabis sativa L.) were at genomic level. The phylogenetic tree members cannabis, Arabidopsis, rice was constructed, all divided into three subgroups: Class I, II, III. number exons motif types among I exactly same, as II members, gene structure III slightly different. There four pairs CsTPSs CsTPPs had duplication, indicating duplication events played an important role amplification families cannabis. results expression analysis under abiotic stresses showed 68.75 % CsTPS CsTPP significantly induced by least one stress. Among these genes, CsTPS1, CsTPS9, CsTPPA highest These may play stress responses. Most closely located evolutionary same or similar functions. To our knowledge, first paper reports
