We have characterized the nucleotide sequences of the 70-kDa heat shock protein (HSP70) genes of Cryptosporidium baileyi, C. felis, C. meleagridis, C. muris, C. serpentis, C. wrairi, and C. parvum from various animals. Results of the phylogenetic analysis revealed the presence of several genetically distinct species in the genus Cryptosporidium and eight distinct genotypes within the species C....

Polyploidy is a prominent and significant force in plant evolution, taking place since ancient times and continuing until today. Recent cytogenetic studies in the genus Brachiaria using germplasm collected from wild African savannas in the 1980s revealed that most species and accessions within species are polyploid. Diploid, tetraploid, and pentaploid accessions have been found. We found asynch...

orobanche aegyptiaca, commonly known as egyptian broomrape, is a holo-parasite that causes high economic damages on tomato production in iran. breeding for resistance is the most economic and feasible method to reduce broomrape infestation. 20 tomato cultivars and four wild tomato species were screened for o. aegyptiaca resistance. tomato yield reduction, dry weight reduction of shoot and root,...

Almond is one of the most important nut crops in Iran. Due to the suitable climatic conditions, Iran is one of the most important growing centers for wild and domesticated species of almond in world. Native genotypes typically are early flowering, due to late spring frost, often; they have been damaged. So frost damage to the flowers and early developing fruits is one of the most limiting facto...

This review summarizes the major biological, biochemical and molecular methods which have been developed during last 20 years to distinguish parasites of the genus Trichinella. From the time of the discovery of Trichinella in 1835 until the 1970, it was assumed that trichinellosis was caused by a single species of parasite, Trichinella spiralis. Many biological parameters have been compared to ...

The production and proper utilization of medicinal plants in natural habitats need to review and identify the natural conditions and climate of the habitat of these plants and separating them from harmful and poisonous plants. The current study was aimed to introduce and determine the distribution of medicinal plants from Lamiaceae family in Mazandaran province as well as the introduction of na...
