“…Phytoplasma diseases of date palms have been reported from Egypt, Kuwait, Saudi Arabia and Sudan (Al-Awadhi et al, 2002;Alhudaib et al, 2008;Alhudaib et al, 2014;Al Khazindar, 2014;Ammar et al, 2005;Cronjé et al, 2000;El-Zayat et al, 2002). Thus far, the phytoplasma groups implicated in these disease have been identified as group 16SrI (Egypt and Saudi Arabia) (Alhudaib et al, 2008;Al Khazindar, 2014), 16SrII (Saudi Arabia) (Alhudaib et al, 2014) and 16SrXIV (Sudan) (Cronjé et al, 2000).…”

“…P. palmicola" with wild naturalized palm species in the world. A Bermuda grass white leaf phytoplasma related strain has been detected in date palm in North Sudan (Cronje et al, 2000). Palm species other than C. nucifera have been found harbouring lethal yellowing phytoplasma in other parts of the world.…”

In this study, potential alternate hosts of the phytoplasma causing coconut lethal yellowing disease (CLYD) in Mozambique were investigated based on 16S rRNA and secA genes. The results reveal that the naturalized palm species, Elaeis guineensis and Borassus aethiopum are alternate hosts of CLYD phytoplasma in Mozambique. Based on the iPhyClassifier online software, the phytoplasma detected in B. aethiopum belongs to the 16Sr group XXII-A, which include 'Candidatus Phytoplasma palmicola' and 'Candidatus Phytoplasma cocosnigeriae'. This is the first report associating 'Candidatus Phytoplasma palmicola' with wild naturalized palm species in the world.

A disease with symptoms similar to palm lethal yellowing was noticed in the early 2013 in Khuzestan Province (Iran) in date palm (Phoenix dactylifera). Infected trees displaying symptoms of streak yellows and varied in the incidence and severity of yellowing. A study was initiated to determine whether phytoplasma was the causal agent. Polymerase chain reaction–restriction fragment length polymorphism (PCR‐RFLP) methods using universal phytoplasma primers pairs R16mF1/mR1 and M1/M2 were employed to detect putative phytoplasma(s) associated with date palm trees. Nested PCR using universal primers revealed that 40 out of 53 trees were positive for phytoplasma while asymptomatic date palms from another location (controls) tested negative. RFLP analyses and DNA sequencing of 16S rDNA indicated that the presence of two different phytoplasmas most closely related to clover proliferation (CP) phytoplasma (group 16SrVI) and ash yellows (AY) phytoplasma (group 16SrVII). Sequence analysis confirmed that palm streak yellows phytoplasmas in each group were uniform and to be phylogenetically closest to “CandidatusP. fraxini” (MF374755) and “Ca. P. trifolii” isolate Rus‐CP361Fc1 (KX773529). Result of RFLP analysis of secA gene of positive samples using TruI and TaqI endonuclease is in agreement with rDNA analysis. On this basis, both strains were classified as members of subgroups 16SrVI‐A and 16SrVII‐A. This is the first report of a phytoplasma related to CP and AY phytoplasma causing date palm yellows disease symptoms.
