An Investigation of Apple Chlorotic Leaf Spot (ACLSV) and Tomato Ring Spot (ToRSV) in Some Iranian Pear Gardens
Background and Aims: In spite of a long tradition of fruit-tree growing in all provinces of Iran, information on pear (Pyrus communis) tree viruses is scant. In order to identify of the nature of the virus like symptoms and decline in pear trees, we carried out a survey for the occurrence of four important viruses. Materials and Methods: Leaf samples of pear showing virus like symptoms wer...
متن کاملthe first report of stenotrophomonas sp. associated with canker and leaf spot disease of stone fruits in iran
department of plant protection, faculty of agriculture, vali-e-asr university of rafsanjan. *.corresponding author, [email protected] in september of 2012 some bacterial strains were isolated from peach (prunuspersica),apricot (prunusarmeniaca)and sour cheery (prunuscerasus)trees with leaf spot, canker and dieback symptoms on twig and stem in alborz province. the symptoms were similar to tho...
متن کاملErwinia tasmaniensis sp. nov., a non-phytopathogenic bacterium from apple and pear trees.
Bacteria were isolated from flowers and bark of apple and pear trees at three places in Australia. In Victoria, Tasmania and Queensland, strains with white colonies on nutrient agar were screened for dome-shaped colony morphology on agar with sucrose and were found to be closely related by several criteria. The isolates were not pathogenic on apples or pears. They were characterized by a polyph...
متن کاملEnterobacter sacchari sp. nov., a nitrogen-fixing bacterium associated with sugar cane (Saccharum officinarum L.).
Five nitrogen-fixing bacterial strains (SP1(T), NN143, NN144, NN208 and HX148) were isolated from stem, root or rhizosphere soil of sugar cane (Saccharum officinarum L.) plants. Cells were Gram-negative, motile, rods with peritrichous flagella. DNA G+C content was 55.0 ± 0.5 mol%. Sequence determinations and phylogenetic analysis of 16S rRNA gene and rpoB indicated that the strains were affilia...
متن کاملPhylogenetic analysis of Alloiococcus otitis gen. nov., sp. nov., an organism from human middle ear fluid.
The partial 16S rRNA sequence of an unknown bacterium that was originally isolated from middle ear fluids of children with persistent otitis media was determined by reverse transcription. A comparison of this sequence with sequences from other gram-positive species having low guanine-plus-cytosine contents revealed that this bacterium represents a new line of descent, for which the name Alloioc...
