摘要: A 2.9 kbp EcoRi fragment from chloroplast DNA of a tree species Populus deltoides, has been cloned. Nucleotide sequence analysis led to the identification 1062 bp open reading frame located at one end recombinant clone. This more than 94% nucleotide homology with tobacco and cotton psbA genes. The deduced amino acid poplar gene is highly homologous differs only by 2 acids C-terminus protein. An AT rich region, capable forming potential stem-loop structure was down stream gene. Our Southern hybridization data confirms presence IR region as well location near in P. deltoides.
