molecular characterization of aster yellows phytoplasma associated with citrus varieties, using multiplex pcr
a survey was carried out in citrus nurseries in mazandaran and kerman provinces as the major citrus growing regions of iran. different varieties of orange and tangerine with abnormal symptoms were examined for the occurrence of candidatus liberobacter asiaticus, spiroplasma citri and phytoplasma as the most important vascular limited pathogens in citrus. by visual inspection and molecular exami...
متن کاملa 16srii-d phytoplasma strain associated with tomato witches'- broom in bushehr province, iran
in 2010- 2012 surveys, witches'- boom disease of tomato was observed in borazjan area (bushehr province, iran). agent of the disease was transmitted from tomato to tomato and eggplant by grafting and to madagascar periwinkle via dodder inoculation, inducing phytoplasma-type symptoms in inoculated plants. presence of phytoplasma in naturally affected tomatoes and all symptomatic graft and dodder...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
"Candidatus phytoplasma australiense," a new phytoplasma taxon associated with Australian grapevine yellows.
A phytoplasma was detected in naturally diseased 'Chardonnay' grapevines exhibiting symptoms of Australian grapevine yellows disease. The use of PCR designed to amplify phytoplasma DNA resulted in detection of phytoplasma DNA in all of the diseased plants examined; no phytoplasma DNA was detected in healthy seedling grapevines. The collective restriction fragment length polymorphism (RFLP) patt...
متن کاملThe phytoplasma associated with ash yellows and lilac witches'-broom: 'Candidatus phytoplasma fraxini'.
Phytoplasmas associated with the plant diseases ash yellows (AshY, occurring in Fraxinus) and lilac witches'-broom (LWB, occurring in Syringa) represent a putative species-level taxon. Phytoplasmal DNA from 19 ash or lilac sources across the known geographic range of AshY (71-113 degrees W) was examined to determine if AshY and LWB phytoplasmas are a coherent group, if variability exists in bot...
