Classification of aster yellows-group phytoplasmas based on combined analyses of rRNA and tuf gene sequences.
Seventy phytoplasma isolates, including 10 previously characterized reference strains, of the aster yellows group were examined by RFLP analysis of PCR-amplified rDNA and RFLP and sequence analysis of the tuf gene. On the basis of rDNA restriction profiles, seven previously proposed 16S rDNA subgroups (16SrI-A, -B, -C, -D, -E, -F and -K) were recognized in the material examined. In addition, th...
متن کاملSecY gene sequence analysis for finer differentiation of diverse strains in the aster yellows phytoplasma group.
Aster yellows (AY) group (16SrI) phytoplasmas are associated with more than 100 economically important diseases worldwide and represent the most diverse and widespread phytoplasma group. Phylogenetic analysis of secY gene sequences resolved 10 genetically distinct lineages. The 10 lineages coincide with those delineated by phylogenetic analysis based on ribosomal protein (rp) gene sequences. Ho...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
Classification of new phytoplasmas associated with diseases of strawberry in Florida, based on analysis of 16S rRNA and ribosomal protein gene operon sequences.
Strawberry plants exhibiting symptoms of stunting and abnormally small leaves were observed in production fields in central Florida, USA. Since the symptoms were suggestive of phytoplasma infection, plants were assayed for presence of phytoplasma by PCR amplification of 16S rDNA and ribosomal protein (rp) gene sequences. Amplification of phytoplasma-specific DNA sequences by PCR indicated infec...
