Study on botanical characteristics and genetic traits of Homonoia riparia Lour. in Viet Nam

Abstract

The willow-leaved water croton, which is called “rì rì” in Vietnamese, was
collected in Quang Ngai Province for the study on botanical characteristics and genetic
traits by employing molecular marker technique. Some outstanding particular macrocopic
and specific microscopic features were defined. Fresh leaves were used to analyze gene
sequences based on rbcL region amplified by PCR. Sequences of DNA products were
identified by Sanger method and BioEdit 7.0.5 software, then compared to the control rbcL
sequences published in GenBank by BLAST. The taxonomical identification result showed
that the material plant was Homonoia riparia Lour., Euphorbiaceae.
