Abstract
In this study, the taxonomic position and group classification of the phytoplasma associated with a lethal yellowing-type disease (LYD) of coconut (Cocos nucifera L.) in Mozambique were addressed. Pairwise similarity values based on alignment of nearly full-length 16S rRNA gene sequences (1530 bp) revealed that the Mozambique coconut phytoplasma (LYDM) shared 100 % identity with a comparable sequence derived from a phytoplasma strain (LDN) responsible for Awka wilt disease of coconut in Nigeria,

‘Candidatus Phytoplasma malaysianum’, a novel taxon associated with virescence and phyllody of Madagascar periwinkle (Catharanthus roseus)

Names

Abstract
This study addressed the taxonomic position and group classification of a phytoplasma responsible for virescence and phyllody symptoms in naturally diseased Madagascar periwinkle plants in western Malaysia. Unique regions in the 16S rRNA gene from the Malaysian periwinkle virescence (MaPV) phytoplasma distinguished the phytoplasma from all previously described ‘ Candidatus

First Report of “Candidatus Phytoplasma Asteris”-Related Strains Infecting Chinaberry Trees with Leaf Yellowing Symptoms in Vietnam

Abstract
Although no loss of crown shape or unusual growth were evident on two mature Chinaberry trees (Melia azedarach L.) located near the citadel in central Hué city, Vietnam, leaves on both trees displayed distinctive interveinal yellowing during September 2003. This symptom was reminiscent in appearance to foliar discoloration previously observed on mature Chinaberry trees in El Torno, Santa Cruz, Bolivia that was subsequently attributed to phytoplasma infection of these trees (2). Eight samples of
