1Molecular evidence for natural hybridization between Sonneratia alba and S. griffithii显示文摘Interspecific hybridization has been frequently observed in the mangrove genus Sonneratia. However, no natural hybridization has been reported between Sonneratia alba and S. griffithii to date, despite their overlap-ping distribution in the coast of Andaman Sea. In this study, cysteine proteinase inhibitor gene (cpi) from the nuclear genome, and two intergenic spacers (trnL-trnF and trnV-trnM) from the chloroplast genome, were se-quenced to determine whether natural hybridization took place between the two species. Our results revealed two distinct types of cpi sequences from the putative hybrid matching those acquired from S. griffithii and S. alba, respectively. Sequencing of the chloroplast trnL-trnF and trnV-trnM regions showed that S. alba differed from S. griffithii by one nucleotide in each region, and the putative hybrid had the identical sequences with S. griffithii. Molecular data demonstrated clearly that there indeed existed natural hybridization between S. alba and S. grif-fithii, and that S. griffithii was the maternal parent in this hybridization event.Suo QIU Ren-Chao ZHOU Yun-Qin LI Sonjai HAVANOND Chanop JAENGJAI Su-Hua SHI 2008植物分类学报2008,46,3:2
