Sugarcane Grassy Shoot (SCGS) disease is known to be related to Rice Yellow Dwarf (RYD) phytoplasmas (16SrXI-B group) which are found predominantly in sugarcane growing areas of the Indian subcontinent and South-East Asia. The 16S rRNA gene sequences of SCGS phytoplasma strains belonging to the 16SrXI-B group share 98.07 % similarity with 'Ca. Phytoplasma cynodontis' strain BGWL-C1 followed by 97.65 % similarity with 'Ca. P. oryzae' strain RYD-J. Being placed distinctly away from both the… 
Draft genome sequence of ‘Candidatus Phytoplasma australasia’, strain SS02 associated with sesame phyllody disease
The genome sequence of strain SS02 was obtained using its genomic DNA enrichment and hybrid assembly of sequences generated on Illumina and Oxford Nanopore Technologies MinION platforms and generated a draft genome draft sequence containing 465 protein-coding genes, 17 tRNA genes, and 3 rRNA genes.
Geographical Distribution and Identification of Phytoplasma Strain Associated with Sugarcane White Leaf Disease in Sri Lanka
The geographical distribution of phytoplasma strains associated with SCWL in Sri Lanka, identification of their weed reservoirs and ribosomal subgroup analysis based on phy Toplasma 16S rRNA gene were carried out and the phy toplasma subgroup 16SrXI-B was identified as the most widespread SCWW phytopsomnia subgroup in commercial sugarcane varieties in Sri Sri Lanka.
Identification of Phytoplasmas Representing Multiple New Genetic Lineages from Phloem-Feeding Leafhoppers Highlights the Diversity of Phytoplasmas and Their Potential Vectors
Ten phytoplasma-harboring leafhoppers belonged to seven known leafhopper species, none of which were previously reported insect vectors of phy toplasmas, and these strains extend previously undiscovered geographical distributions.
Revision of the 'Candidatus Phytoplasma' species description guidelines.
The genus 'Candidatus Phytoplasma' was proposed to accommodate cell wall-less bacteria that are molecularly and biochemically incompletely characterized, and colonize plant phloem and insect vector
Our understanding about phytoplasma research scenario in India
Since the first report of existence of phytoplasma disease in 1874 in India, now more than 172 plant species are reported to be the host of ten different groups of phytoplasmas. The phytoplasma
Comparative Genome Analysis of ‘Candidatus Phytoplasma luffae’ Reveals the Influential Roles of Potential Mobile Units in Phytoplasma Evolution
This work utilized Illumina and Oxford Nanopore sequencing technologies to obtain the complete genome sequence of ‘Candidatus Phytoplasma luffae’ strain NCHU2019 that is associated with witches’ broom disease of loofah (Luffa aegyptiaca) in Taiwan and provides novel information regarding the roles of mobile genetic elements in phy toplasma evolution.
Screening potential insect vectors in a museum biorepository reveals undiscovered diversity of plant pathogens in natural areas
Museum collections of herbivorous insects represent a rich and largely untapped resource for discovery of new plant pathogens, that natural areas worldwide harbor a diverse but largely undiscovered diversity of phytoplasmas and potential insect vectors, and that independent epidemiological cycles occur in such habitats, posing a potential threat of disease spillover into agricultural systems.
Plants and Phytoplasmas: When Bacteria Modify Plants
Plant pathogen presence is very dangerous for agricultural ecosystems and causes huge economic losses. Phytoplasmas are insect-transmitted wall-less bacteria living in plants, only in the phloem
Silencing of ATP Synthase β Impairs Egg Development in the Leafhopper Scaphoideus titanus, Vector of the Phytoplasma Associated with Grapevine Flavescence Dorée
The effectiveness of RNAi in S. titanus provides a powerful tool for functional genomics of this non-model species and paves the way toward RNAi-based strategies to limit vector population, despite several technical and regulatory constraints that still need to be overcome to allow open field application.


New subgroup 16SrXI-F phytoplasma strain associated with sugarcane grassy shoot (SCGS) disease in India.
The 16S rRNA gene-based phylogenetic analysis of reported RYD and BGWL group phy toplasmas showed that they are a genetically diverse group of phytoplasmas.
'Candidatus Phytoplasma cirsii', a novel taxon from creeping thistle [Cirsium arvense (L.) Scop].
It could be concluded that the studied phytoplasma strains represent a discrete group that is proposed as a novel taxon 'Candidatus Phy toplasma cirsii', with strain CirYS as a reference strain.
"Candidatus Phytoplasma oryzae", a novel phytoplasma taxon associated with rice yellow dwarf disease.
In addition to rice yellow dwarf (RYD) phytoplasma, several phytoplasmas infect gramineous plants, including rice orange leaf, bermuda grass white leaf, brachiaria grass white leaf and sugarcane
Phylogenetic analysis identifies a 'Candidatus Phytoplasma oryzae'-related strain associated with yellow leaf disease of areca palm (Areca catechu L.) in India.
The 16S rRNA and secA gene sequences of the Indian arecanut YLD phytoplasma are characterized for 'Candidatus Phy toplasma' species assignment and 16Sr group/subgroup classification and the phy Toplasma is named, to differentiate it from the Hainan YLDphytop lasma, which belongs to group 16SRI.
'Candidatus Phytoplasma cynodontis', the phytoplasma associated with Bermuda grass white leaf disease.
It can be concluded that the BGWL phytoplasma is a discrete taxon at the putative species level, for which the name 'Candidatus Phy toplasma cynodontis' is proposed.
Detection of sugarcane grassy shoot phytoplasma infecting sugarcane in India and its phylogenetic relationships to closely related phytoplasmas
The extensive survey of phytoplasmal infections in sugarcane plants in India as well as analysis of phylogenetic relationships of SCGSphytoplasma strains to each other and to other closely related phy toplasmas, had previously not been known.
Genetic Diversity of Sugarcane Grassy Shoot (SCGS)-Phytoplasmas Causing Grassy Shoot Disease in India
Results proved that the phytoplasma isolates infecting sugarcane in India with phenotypic variations from different regions have similar ITS region and further studies are needed to locate other genes in phy toplasma genome which determine variations in phenotypesic expression in the SCGS disease.
New Efficient Natural Leafhopper Vectors of Sugarcane Grassy Shoot Phytoplasma in India
The identification of new vectors of SCGS phytoplasma suggested that these leafhopper species may be responsible for secondary spread of SC GS phy toplasma.
Molecular and Symptom Analysis Reveal the Presence of New Phytoplasmas Associated with Sugarcane Grassy Shoot Disease in India.
Two phytoplasmas may be previously unreported ones that cause significant yield losses in sugarcane in India, and two of them, namely BV2 and VD7, shared relatively low sequence similarity.
'Candidatus Phytoplasma', a taxon for the wall-less, non-helical prokaryotes that colonize plant phloem and insects.
The trivial name 'phytoplasma' has been adopted to collectively name wall-less, non-helical prokaryotes that colonize plant phloem and insects, which were formerly known as mycoplasma-like organisms.
