First report of ‘Candidatus Phytoplasma asteris’ (16Sr I group) associated with yellows and little leaf diseases of Hibiscus rosa‐sinensis in India

Evidence of association of a ‘Candidatus Phytoplasma cynodontis’ with bermuda grass (Cynodon dactylon) and ‘Candidatus Phytoplasma asteris’ with periwinkle (Catharanthus roseus) from western Uttar Pradesh, India

“…Under field conditions various phytoplasma specific symptoms were observed like whitening of leaves, phyllody, virescences, yellowing of leaves and small leaves in bermuda grass and periwnkle. Similar observations were recorded in bermuda grass by Gaur et al (2011) in Rajasthan, India, Rao et al (2007) in India and in periwinkle by Chaturvedi et al (2010) in Eastern Uttar Pradesh: Omar et al (2008) in Egypt, Moreno et al (1985) in Spain and Nejat et al (2010) in Malaysia. In previous works many BGWL strains from different geographical areas were examined by RFLP analysis of PCR amplified rDNA by various restriction enzymes (Marcone et al, 1997;Wongkaew et al, 1997;Lee et al, 1998;Tran-Nguyen et al, 2000).…”

“…Phytoplasma asteris'. Kumar and Byadgi (2012) based on virtual RFLP, predicted that the little leaf disease of periwinkle from Dharwad, belongs to 16S rDNA I-B phytoplasma group and Chaturvedi et al, 2010 reported 'Ca. Phytoplasma asteris' isolate associated with yellows and little leaf disease of Hibiscus rosa-sinensis from different gardens and nurseries of Gorakhpur, Eastern Uttar Pradesh, India, during June 2008.…”

Plant, Soil and Microbes

“…in the United Kingdom, whileZhang et al ( 2009 ) reported aster yellows group phytoplasma associated with a leaf roll disease in shiny leaf yellowhorn in China. Similarly,Chaturvedi et al ( 2010b ) reported the little-leaf disease in Hibiscus rosa-sinensis in Gorakhpur. However, observed the presence of phytoplasmas in fi ve ornamental plants, namely, Alstroemeria , Duranta , Streblus , Petunia , and Zenia , from the gardens of Uttar Pradesh and Uttarakhand.…”

Molecular characterization and phylogeny of phytoplasma associated with bunchy top disease in its new host Okra (Abelmoschus esculentus) in India reveal a novel lineage within the 16SrI group

“…Earlier reports have shown the susceptibility of various Malvaceae members for phytoplasma, such as cotton which commonly suffers from virescence (Marzachi et al 2009) and little leaf (Kumar et al 2010b), Hibiscus with witches'-broom (Montano et al 2001) and little leaf yellowing disease (Chaturvedi et al 2009), and Sida with small leaf, witches'-broom (Eckstein et al 2011). The host plant okra is a new addition to this list.…”
