Identification and Analysis of WOX Gene Family in Lettuce
WOX transcription factors are plant-specific members.Previous studies have shown that WOX family members play an important role in plant growth and development and abiotic stress response,but the biological functions of WOX gene family remain unknown in lettuce(Lactuca sativa L.).In this study,we identified and characterized 14 putative LsaWOX genes in lettuce.Their gene structure,protein conserved motif,three-dimensional structure,chromosome location and c is-acting elements were analyzed.These members could be classified into three subfamilies,and they are ancient clade,intermediate clade and WUS clade.In this study,WOX family members in lettuce were identified and preliminarily analyzed to provide a theoretical basis for further research on the biological functions of WOX gene family in lettuce.
