Simultaneous and Visual Assay for Three 16Sr Groups of ‘Candidatus Phytoplasma’ Infecting Date Palm (Phoenix dactylifera L.) Targeting 16S rRNA Gene Sequences

Agriculture
Date palm is a staple food crop and crucial export agricultural commodity in Arab countries. Date palm diseases caused by phytoplasmas are devastating diseases that severely constrain the sustainable development of date palm cultivation and industry. The

Insect transmission of phytoplasmas

, 2016
Phytoplasmas are phloem-limited, wall-less bacteria that are associated with disease in several hundred cultivated and wild plant species. Symptoms induced by phytoplasma infections are flower malformation (virescence, phyllody), growth aberration ...

Current status of molecular classification of the phytoplasmas [PDF]

, 1998
Phytoplasmas for which 16S rDNA sequences are available have been classified into 20 major phylogenetic groups or subclades. Further phytoplasmas have been assigned to these groups, according to other molecular data such as RFLP analysis of PCR ...
