| molecular diversity of turncurtoviruses in iran. | turnip curly top virus (tctv) is the only member of the newly established genus turncurtovirus (family geminiviridae). as part of an ongoing study to identify additional plant hosts and the diversity of turncurtoviruses, between 2012 and 2014, we sampled symptomatic turnip plants and other crops in the provinces fars and khorasan razavi (southern and northeastern iran, respectively). infection by turncurtoviruses was tested by pcr and/or rolling-circle amplification (rca) coupled with restrictio ... | 2016 | 26611911 |
| diversity of beet curly top iran virus isolated from different hosts in iran. | beet curly top iran virus (bctiv) is a major pathogen of sugar beet in iran. in order to study diversity of bctiv, we sampled 68 plants in iran during the summer of 2010 with curly top disease symptoms on beans (phaseolus vulgaris), cowpeas (vigna unguiculata), tomatoes (solanum lycopersicum l.), sea beets (beta vulgaris subsp. maritima), and sugar beets (beta vulgaris). plant samples showing leaf curling, yellowing, and/or swelling of veins on the lower leaf surfaces were collected from various ... | 2013 | 23329008 |
| occurrence of plant parasitic nematodes (tylenchina) in sugar beet fields in fars province, iran. | on a survey of plant parasitic nematode fauna, belonging to the suborder tylenchina, about 110 soil and root samples were collected from different sugar beet field in fars province in iran. the samples were washed and the nematodes were extracted by centrifugal flotation technique according to the modified method by de grisse, 1969. they were fixed and transferred to glycerine, then permanent slides were mounted. morphological and morphometrical characters of collected species were carefully stu ... | 2004 | 15759441 |
| evidence for presence of types a and b of beet necrotic yellow vein virus (bnyvv) in iran. | rhizomania a viral disease, caused by beet necrotic yellow vein benyvirus (bnyvv), is now widely spread, throughout the sugar beet growing areas of iran. genomes of bnyvv are composed of five rna molecules with specific functions. in this study sequence analyses were conducted on the major coat protein gene (cp21), and parts of rna3 and rna4 of an iranian strain of bnyvv from the fars province. sequence alignments of iran fars cp21 with other isolates showed closed similarities at nucleotide and ... | 2004 | 15550776 |
