“…4C). While infections of parthenium weed by a subgroup 16SrII-A phytoplasma was reported 1 previously in Hainan Island, China (Li et al, 2011), this is the first time parthenium weed is recognized as 1 a natural host of a subgroup 16SII-A phytoplasma in Yunnan, and the first time that a link is drawn between 1 the weed and diseases in agricultural crops. 1 Ubiquitous presence of parthenium weed in the vicinity of vegetable production fields and the ability of 1 the weed to host subgroup 16SrII-A phytoplasma pointed to a possibility that the weed plants served as a 1 reservoir for spreading the phytoplasma to nearby vegetable plants by a yet to be identified insect vector in 1 the region.…”

“…5). It is worth noting that infection of parthenium weed by a subgroup 16SrII-A phytoplasma was reported previously in Hainan (Li et al, 2011) but the imp gene of the Hainan parthenium weed phytoplasma has yet to be characterized and no etiological study has been conducted to link parthenium weed and any other phytoplasmal diseases in Hainan. Findings from the present study may shed light on identification of potential reservoir(s) of subgroup 16SrII-A phytoplasmas in Hainan and Taiwan islands.…”

During the period from 2011 to 2013, several plant diseases repeatedly occurred in vegetable crops grown 4 in Yuanmou County, Yunnan Province, China. Affected plants included cowpea, sword bean, string bean, 5 tomato, lettuce, and water spinach. The diseased plants exhibited symptoms of witches'-broom growth 6 and floral deformations, linking each disease to phytoplasmal infection. Phylogenetic and virtual RFLP 7 analyses of the phytoplasmal 16S rRNA gene sequences amplified from DNA of diseased plants revealed 8 that all of the individual strains present in the diverse vegetable plants were affiliated with a single 9 'Candidatus Phytoplasma' species ('Ca. Phytoplasma aurantifolia') and a single ribosomal subgroup (16SrII-A). While presence of subgroup 16SrII-A phytoplasma in this geographic region was reported previously, such widespread infections in diverse plant hosts are unveiled for the first time in this study. In pursuing the source of the infections, we found that areas surrounding the affected vegetable fields were extensively invaded by parthenium weeds (Parthenium hysterophorus); and many of the weed plants exhibited abnormal morphologies that were suspicious of, and later diagnosed with, phytoplasmal infections. Results from genotyping of 16S rRNA and lineage-specific immunodominant membrane protein genes revealed that the vegetable-infecting phytoplasmas and the parthenium weed phytoplasma belong to the same genetic lineage. The findings indicate that parthenium weed poses a substantial risk as a reservoir of phytoplasmal infection of nearby agricultural crops in the geographic region since the ecosystems of Yuanmou are insect-rich, and parthenium weed is known to attract diverse leafhoppers. Further studies are warranted to assess the impact of farmland invasions by the noxious weed and to devise practical measures for improved weed control.

“…Leaf samples were collected from five symptomatic S. guianensis and S. capitata , respectively; leaf samples from both asymptomatic plants of the both species were used as negative controls. Common Parthenium witches’‐broom phytoplasma (CoPWB), a member of subgroup 16SrII‐A, was used as a phytoplasma reference strain (Li et al. 2011).…”

In July 2008, Stylosanthes guianensis with witches’‐broom symptoms and Stylosanthes capitata with yellows symptoms were observed in Hainan Province, China. From the symptomatic S. guianensis, the phytoplasma‐specific 16S rRNA gene fragment of 1.4 kb was amplified by a direct PCR, and a fragment of 16S rRNA gene of 1.2 kb was obtained from the symptomatic Stylosanthes capitata by a nested PCR. Sequencing results and NCBI BLASTn analysis showed that the two phytoplasmas belonged to group 16SrII. Polygenetic analysis and virtual RFLP classified the two phytoplasmas into subgroup 16SrII‐A.

“…Majority of these genes associated with either host plant resistance mechanisms against various pathogens and pests or the biotic stresses. Thus, the P. hysterophorus plants might have showed greater endurance to biotic and abiotic stresses, and showed its best survival nature baring a few such as witches broom disease (Li et al 2011;Keshwal, 1982;Yadav et al 2015;Fauzi, 2009). Further, the expression pattern of some of the pathogenesis related genes viz; pathogenesis-related protein 1 (PR-1), nematode resistance protein-(HSPRO2), rust resistance kinase Lr10, chitinase1, leaf rust 10 disease-resistance locus receptor-like protein kinase (Like 1.3), and defensin-A3 were evaluated among different tissue of healthy plant as well as phytoplasma infected plants (Table 4; Figure 3) showing symptoms of witches broom disease.…”

Parthenium hysterophorus L. is a notorious weed, which significantly reduce yield and quality of crops and causes several problems to human health. In, present study an attempt was made to understand the economic value, and survival nature of Parthenium through deep transcriptome analysis. Transcriptome analysis of leaf and root tissue of P. hysterophorus had resulted 7,832,143 reads in case of leaves, and 9,646,830 reads in case of roots sample with longest read length of 300 and 298 nucleotides, respectively. A total of 35,719 contigs were produced with an average length of 548bp after an assembly in all two samples. The Blastn of the above generated contigs with 61,901 sequences of P. argentatum resulted in the identification of 25,947 novel contigs specific to P. hysterophorus. The Kyoto Encyclopedia of Genes and Genomes pathway based analysis showed the expression of genes associated with pathways pertaining to biosynthesis of Glucosinolate, Amino acids, and Aminobenzoate degradation etc. The expression pattern of genes like Artemisinic aldehyde Delta (11(13)) reductase, Codeine O-demethylase, Taraxerol synthase, and Curculin-2 related to biosynthetic of therapeutic importance pathways was also evidenced. Further, the heavy metal accumulator property of P. hysterophorus was also studied. Expression analysis of heavy metal transporters such as ferrous ion transport protein B, and zinc transporter in roots was also validated with its heavy metal transport activity. This investigation provides new insights for functional studies of P. hysterophorus genes involved in biosynthesis of therapeutically important secondary metabolites, and other possible uses such as raw material for rubber industry.
