Abstract:
To promote the molecular breeding of Salix psammophila,branching and regulation genetic mechanism was studied. Salix psammophila was used as the experimental material,the SpsLAS2,SpsLAS3 gene of Salix psammophila was cloned by homologous cloning technique and analyzed by bioinformatics and tissue-specific expression.The similarity of SpsLAS2 and SpsLAS3 gene sequences got to 96.69%,and the amino acid sequences similarity got to 97.6%.The sequence lengths of SpsLAS2 and SpsLAS3 were 1 248 bp and 1 254 bp,coding 415 aa and 417 aa,respectively.The amino acid sequences had five typical domains of GRAS gene family and belonged to the LS subfamily.The qRT-PCR in different tissues of Salix psammophila showed that the two genes expressed the highest in the leaf axil,suggesting that the two genes specifically expressed in the leaf axil,and two genes might be involved in the regulation of axillary meristem formation by participating in leaf axillary meristem.It was suggested that the two genes may be tandem gene doubling relationship on the same chromosome.
