(Hart 1) isolated from a coconut palm with hartrot disease. The minicircle possessed a two domain structure of two conserved regions, each containing three conserved sequence blocks (CSB). Based on the sequence around CSB 3 from Hart I, PCR primers were designed to allow specific amplification of Phytomonas minicircles. This primer pair demonstrated specificity for at least six groups of plant trypanosomatids and did not amplify from insect trypanosomatids. The PCR results were consistent with a two-domain structure for other plant trypanosomatids.enConserved sequence blockHartrotMarchitez sorpressivaPolymerase chain reactionPlant trypanosomatidArticle
