numerical taxonomy and seed storage protein analysis of hyoscyamus species of iran was carried out with the aim to illustrate species inter-relationship and to check the sub-generic taxonomic treatment proposed for the genus. cluster analysis of morphological and protein data grouped the species in three separate clusters which supports the relationships of h. niger with h. reticulatus and h. k...

  I n a survey of pneumonia due to Mycoplasma 282 out of 12168 ovine and caprine lung condemnation were collected (2.32%). Mycoplasma spp. has been isolated from pneumonic cases in 4 sheep and 2 goats. PCR studies were confirmed the genus of Mycoplasma although attempting for identification of strains M. mycoides, M. capricolum/caprine pleuropneumonia and M. arginin were in failure. The lesions...

pollen morphology of some species of the genus malus (rosaceae) was investigatedtaxonomically. all species are characteristic by tricolpate pollens. exine sculpturing is variable but is mostlystriate. however, species may differ in degree of density of ridges and their orientation. the exine patterns inm. trilobata and m. florentina are very similar and were characterized by short and very bran...
