Expressed salt stress induced full length-cDNA library of Salix matsudana using yeast Invsc1

Abstract: The studies of Salix matsudana on salt-resistance molecular mechanism and searching new salt-tolerant relation genes are limited at present. It is necessary to develop drought-tolerant gene using this valuable tree resource,so a salt stress induced full-length cDNA Library of Salix matsudana was constructed using Clontech Laboratories,Inc. SMART cDNA Library Construction Protocol. Total RNA was extracted from S. matsudana under 100 mmol·L-1 NaCl stress for 24 h. After synthesizing the first-strand cDNA,the double-strand cDNA was amplified with the long-distance Polymerase Chain Reaction (LD-PCR). The result showed that insertion fragment was about 1 000 bp length in the library by PCR. The full-length cDNA fragment was linked to yeast vector pYES2.1 by pYES2.1 TOPO TA Expression Kit;then the linked product was transferred into yeast Invsc1. Finally,clones were selected by SC-U medium containing 80 - 130 g·L-1 NaCl. The experiment shows that the salt-tolerance of transformants yeast improved greatly compared with the wild-type yeast. The results provide an important tool for the study of cloning new salt-tolerance relation genes and the salt tolerance mechanisms of the S. matsudana. [Ch,6 fig. 17 ref.]
