“…Alfalfa witches' broom (AWB) is one of the most important diseases of alfalfa in the world. It was observed for the first time in United States of America in 1925 (Haskel, 1926) and it was reported in many parts of the world (Graham et al, 1984;Lee et al, 2000). The main disease symptoms associated with AWB are small leaf, dwarfing, yellowing, excessive branching of stems, flower abnormality and plant death.…”

Alfalfa witches' broom (AWB) is one of the most important and destructive diseases of alfalfa in Iran. Based on characteristic disease symptoms and direct and nested polymerase chain reactions, the status of AWB disease was evaluated in different growing areas of Iran. Restriction fragment length polymorphism was used to identify AWB disease associated phytoplasmas. Furthermore, infection rate, disease severity, death rate of infected plant in the summer and winter and overwintering of disease vector were assessed. Based on the results, AWB disease was reported on different alfalfa cultivars in Yazd,

“…The infected alfalfa displayed yellowing, little leaf, shorten internodes, compacted canopy and witches’ broom (Figure f,g). Alfalfa witches’‐broom phytoplasma was firstly reported from the United States (Haskell, ) and then reported from different areas throughout the world (Cook & Wilton, ; Esmailzadeh‐Hosseini et al., ; Graham, Fresheiser, Stuteville, & Erwins, ; Helms, ; Lee et al., ; Menzies, ; Smrtz, Ulrychová, & Jokeš, ). The symptoms of diseased pot marigold were phyllody and proliferation (Figure h,i).…”

“…In addition, these symptoms have been reported to be caused by other groups and subgroups of phytoplasma on C. argentea, that is group 16SrI in Lithuania (Samuitiene & Navalinskiene, 2006) and Iran (Aldaghi & Bertaccini, 2015); subgroup 16SrII-A in China (Chen et al, 2016); and group 16SrVI in Iran (Babaie et al, 2007). phytoplasma was firstly reported from the United States (Haskell, 1926) and then reported from different areas throughout the world (Cook & Wilton, 1985;Esmailzadeh-Hosseini et al, 2015;Graham, Fresheiser, Stuteville, & Erwins, 1984;Helms, 1957;Lee et al, 2000;Menzies, 1946;Smrtz, Ulrychová, & Jokeš, 1981). The symptoms of diseased pot marigold were phyllody and proliferation (Figure 2h, Sesame plants affected by phytoplasma showed symptoms of floral virescence, phyllody, stem fasciation, shortened internodes and cracking of seed capsules (Figure 2j).…”

During 2015–2016, wooden and herbaceous plants growing in parks, boulevards, fields, gardens and forests in Khuzestan province, southwestern Iran, were visually inspected for symptoms resembling phytoplasma. Fifty‐one symptomatic samples from nine different species and one symptomless sample from each plant were collected. Leaf midribs, petioles and the parts of stem cambium were separated and freeze‐dried. Total DNA was extracted using CTAB‐based method and tested for phytoplasma using a nested PCR assay. The expected size amplicons of 16S rDNA were sequenced and compared to those of reference phytoplasmas by BLASTn search and phylogenetic analysis. The consensus 16S rDNA sequence of the detected phytoplasma in narrow cattail related to reference phytoplasma group 16SrVI, “Candidatus Phytoplasma trifolii” while in the other plants were related to reference phytoplasma subgroup 16SrII–D, “Candidatus Phytoplasma aurantifolia.” All isolates showed 98%–99% sequence identity to members of their reference groups. To our knowledge, this is the first report of “Candidatus Phytoplasma aurantifolia”‐related strains infecting the plants of Acacia salicina, Alternanthera ficoidea, Melaleuca citrine, Citrus aurantium throughout the world and Celosia christata in Iran. Furthermore, this study is the first to report the association of a “Candidatus Phytoplasma trifolii”‐related strain with Typha angustifolia worldwide.

“…Forage and silage alfalfa Medicago sativa L. with production of about 21,500,000 tons per year and yield of 33076.9 kg/ha have an important role in Iran agriculture as the fifth producer in the world (FAOSTAT, 2013). AWB disease as one of the most important factors affecting alfalfa production was reported for the first time in the United States of America in 1925 (Haskell, 1926), and after that, reported to occur in many alfalfa growing areas in the world (Smarz et al, 1981;Khadhair et al, 1997;Peters et al, 1999;Jomantiene et al, 2000;Marzachì et al, 2000;Khan et al, 2002;Conci et al, 2005;Jones et al, 2005;Getachew et al, 2007;Li et al, 2012;Starović et al, 2012;Esmailzadeh Hosseini et al, 2015a;2015b;2015c). In Iran, for the first time, AWB symptoms were observed in alfalfa farms in Sistan Baluchestan, Fars and Kerman provinces (Salehi and Izadpanah, 1993b).…”

Alfalfa witches' broom (AWB) is one of the most important alfalfa diseases in Iran. To characterize 16SrII group phytoplasmas associated with this disease, symptomatic and asymptomatic plants were collected during 2013-2015 and subjected to direct and nested polymerase chain reaction (PCR) using P1/P7, R16mF2/R16mR2 and R16F2n/R16R2. PCR amplicons of ~1.8, ~1.4 and ~1.25 kb respectively, were obtained only from all symptomatic plants. Restriction fragment length polymorphism (RFLP) analysis of R16F2n/R2 amplicons showed that the phytoplasma associated with AWB disease were members of 16SrII group subgroups 16SrII-D and-C. Blast analysis of these amplicon sequences and sequence homology of collected strains and strain sequences retrived from GenBank (AWB strains Chahgeer, Juyom and Bushehr) confirmed that AWB phytoplasmas collected from Bafg, Ardakan, Bahabad and Herat (Yazd province), Nikshahr (Sistan-Baluchestan), Bam, Zarand, Jiroft (Kerman province), Bushehr (Bushehr province), Tabas (South Khorasan province), Jowkar (Hamedan province) and Zardenjan (Esfahan province) cluster with phytoplasma strains enclosed in the 16SrII-D subgroup, while AWB strains from Chahgeer (Yazd province) and Juyom (Fars province) cluster with phytoplasma strains in the 16SrII-C subgroup. Based on these results the predominant strains of 16SrII phytoplasmas associated with AWB disease in Iran were classified in the 16SrII-D subgroup. In Ashkezar and Abarkouh in Yazd province entire alfalfa farm was infected with witches' broom disease. In 3 year alfalfa stands in Ashkezar alfalfa farms were plowed due to high incidence of the disease.
