flower morphology of ten fritillaria species of subgenera theresia and fritillaria growing wild in iran is studied using seventy morphological characters. qualitative and quantitative datasets separated taxa into subgenera, sectional and groups. three enigmatic species f. caucasica, f. zagrica (endemic to zagros mountains) and f. pinardii (recently reported from zagros mountains) appeared as cl...

The attitude of policymakers and designers of green space is increasing toward to native-ornamental species to plant in the urban space because of their adaptation and resistance against severe weather and ecological conditions which can result in cost minimization and long-term survival in green spaces. Hence, the current study was carried out in the west of Mazandaran Province on three wild a...

In this study, the karyo-systematic studies on the Iranian wild almond species A .communis L., A. corduchoruom Bornm., A. trichamygdalus woronow, Amygdalus lycioides Var. horrida Spach were done by the karyological methods. The meristem cells of the root tip were used for these studies. In each species, ten suitable metaphase plates were chosen and photographed so that the morphology of the chr...

during autumn and summer 2010 observed species from amaranthus genus were studied in segetal and ruderal environments of hamedan city. in this research, 100 plats randomly were selected and totally 6 species from amaranthus were identified as neophyte wild elements: a. retroflexus l. a. lividus l., a. chlorostachys willd, a. albus l., a. viridus l. and a. blitoides s. watson. dispersal of menti...

Leishmania infantum, an etiologic agent of zoonotic visceral leishmaniasis (VL), is spreading in Iran. Dogs are the main reservoirs but L.infantum has been detected in jackals, foxes and wild rodents too. Despite high number of rodents in the world, the exact role of them in epidemiology of VL is not clear. In recent years the number of sporadic cases of dogs and humans VL has been increased in...

Q. Zhang and R.A. Wing (eds.), Genetics and Genomics of Rice, Plant Genetics and Genomics: Crops and Models 5, DOI 10.1007/978-1-4614-7903-1_2, © Springer Science+Business Media New York 2014 The wild species of the genus Oryza serve as a virtually untapped reservoir of genetic diversity that can be used to improve the world’s most important food crop—rice. The genus is composed of two domestic...

ten solanum tuberosum cultivars and accessions from 11 wild solanum species were evaluated for their tolerance to salt (200 mm nacl or 100 mm na2so4), drought (35% peg), cold (-4ºc) and heat (37ºc). evaluation was based on electrolyte leakage from de-tached leaves of in vitro plantlets. testing involved a rinsing treatment with three changes of distilled water to remove electrolytes from leaf a...

Plant microbiome assembly is a spatial and dynamic process driven by root exudates influenced soil type, plant developmental stage genotype. Genotype-dependent has been reported for different crop species. Despite the effect of genetics on assembly, magnitude host control over its relatively small or, many species, still largely unknown. Here we cultivated modern wild tomato genotypes four succ...

Cryptosporidium is increasingly recognized as one of the major causes of moderate to severe diarrhoea in developing countries. With treatment options limited, control relies on knowledge of the biology and transmission of the members of the genus responsible for disease. Currently, 26 species are recognized as valid on the basis of morphological, biological and molecular data. Of the nearly 20 ...
