Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of four phytoplasmas of tuber‐forming Solanum spp. known to occur only outside the EU or having a limited presence in the EU . The only tuber‐forming species of Solanum reported to be phytoplasma infected is S. tuberosum . This opinion covers ‘ Candidatus Phytoplasma americanum’, ‘ Ca . P. aurantifolia’‐related strains ( GD 32; St_ JO _10, 14, 17; PPT ‐ SA ; Rus‐343F; PPT ‐ GTO 29, ‐ GTO 30, ‐ SINTV ; Potato Huayao Survey 2; Potato hair sprouts), ‘ Ca . P. fragariae’‐related strains ( YN ‐169, YN ‐10G) and ‘ Ca . P. pruni’‐related strains (Clover yellow edge; Potato purple top AK pot7, MT 117, AK pot6; PPT ‐ COAHP , ‐ GTOP ). Phytoplasmas can be detected by molecular methods and are efficiently transmitted by vegetative propagation. Phytoplasmas are also transmitted in a persistent and propagative manner by some insects belonging to families within Cicadomorpha, Fulgoromorpha and Sternorrhyncha (order Hemiptera). No transovarial, pollen or seed transmission has been reported. The reported natural host range of the phytoplasmas categorised here varies from restricted (‘ Ca . P. americanum’, and ‘ Ca . P. fragariae’‐related strains) to wide (‘ Ca . P. aurantifolia’‐related strains and ‘ Ca . P. pruni’‐related strains), thus increasing the possible entry pathways in the latter case. S. tuberosum is widely cultivated in the EU . All the categorised phytoplasmas can enter and spread through the trade of host plants for planting, and by vectors. Establishment of these phytoplasmas is not expected to be limited by EU environmental conditions. The introduction of these phytoplasmas in the EU would have an economic impact. There are measures to reduce the risk of entry, establishment, spread and impact. Uncertainties result from limited information on distribution, biology and epidemiology. All the phytoplasmas categorised here meet the criteria evaluated by EFSA to qualify as potential Union quarantine pests, and they do not meet all the criteria to qualify as potential regulated non‐quarantine pests, because they do not occur or are not known to be widespread in the EU . ...

“…Many cucurbits belongs to the Cucurbitaceous family have been infected with different phytoplasma has been well documented in different parts of the world that includes witches' broom of Cucurbita pepo in India (Rao et al 2017), cucumber phyllody in Iran (Hosseini et al 2015) and cucumber yellows (Valiunas et al 2017). Yellows of C. maxima, (McCoy et al, 1989), C. moschata (Montano et al 2006), Luffa cylindrica L. (Lee et al 1993;Gundersen et al 1994), Momordica charantia L.

Based on the 16Sr RNA gene analysis, 16 different ribosomal groups and subgroups phytoplasmas infecting different vegetable crops have been well documented across the world (Kumari et al 2019).…”

Cucumber (Cucumis sativus) plants exhibiting typical phyllody symptoms were collected from farmers field of Chintamani, Chickballapur districts of Karnataka (India). Disease incidence of phyllody was 2-3%. The etiology of the cucumber phyllody phytoplasma (CuPP) was confirmed by amplifying 16S rRNA gene from symptomatic plants using PCR followed by nested PCR using universal primers pairs P1/P7 and R16F2n/R16R2. After general detection the non-ribosomal SecY and rp (ribosomal protein) genes was amplified using specific primers. The PCR amplified products 16SrRNA (1.2 kb), SecY (1.6 kb) rp gene (1.2 kb) was cloned and sequenced. Sequence and phylogenetic analyses of 16S rRNA, secY and rp genes revealed that the detected phytoplasma is a member of the 16SrI group (Candidatus Phytoplasma asteris). Further on the basis of computer-simulated RFLP (= in silico RFLP) analysis of amplified F2n/R2 region of 16S rRNA gene indicates that, the detected phytoplasma was belongs to the subgroup X (16SrII-X). This is the first report on phytoplasma associated with phyllody disease of cucumber in India.

“…Bitter gourd (Momordica charantia L.) belongs to the family Cucurbitaceae is a popular vegetable that having considerable nutritional, economic and medicinal importance (Singh AK, et al, 2007). It is widely cultivated in Asia, Africa, and the Caribbean due to its edible fruit and medicinal properties (Alves MS, et al, 2017). Momordica charantia polysaccharide has the physiological functions of clearing away heat and detoxification, lowering blood sugar, improving immunity and so on.…”

Momordica charantia, commonly called bitter melon, is a plant belonging to Cucurbitaceae family known for centuries for its nutritional properties. This plant have been used as folklore medicine for the management of hypertensions, cold, cough, and diabetes. The aim of the present study was to characterize the chemical constituents of ripe M. charantia from Lombok, Indonesia by Gas Chromatography Mass Spectrometry (GCMS). The method that used is maseration with ethanol as solvent. The ethanol extract of ripe M. charantia was characterized by gas chromatography-flame ionization detection and gas chromatography coupled with mass spectrometry analyses. The chemical constituent of ripe M. charantia that followed by GCMS were 2,4-Pentanediol (23,61 %), Eucalyptol (1,8-Cineole) (20,41 %), Trans (Beta)-Caryopyllene (10,07 %), 3-Decyn-2-ol (9.54 %), Epiglobulol (7.82 %), Methyleugenol (7.15%), Beta-Selinene (5.80 %), Alpha-Selinene (5.43 %), and Alpha-Humulene (5.29 %). This is the first report on chemical screening of ethanol extract of ripe M. charantia and GC-MS analysis shows the presence of compounds which have medicinal properties.
