As a complement to morphological research on the genus Isatis (Brassicaceae), an anatomical study was conducted on the fruit, leaf and stem of 18 species and four subspecies of this genus, as well as two species belonging to the genusPachypterygium. Inclusion of the members of the later genus in the study was to clarify the evidences that supported their affinity to the genus Isatis. As a resul...

the genus phaneroserphus pschorn–walcher, 1958 is recorded for the first time from iran and its allied species, phaneroserphus punctibasis townes, 1981 is recorded from west palaearctic region for the first time. the specimens were collected from mazandaran province during 2011 using malaise traps. diagnostic characters and geographical distribution of the newly recorded genus and species is br...

the brush-tailed mice of the genus calomyscus are distributed in the mountains of central asia and the middle east. the genus calomyscus represents five nominate species from iran (c. bailwardi, c. grandis, c. hotsoni, c. urartensis and c. elburzensis). in total 64 specimens from four species of calomyscus were studied for morphometric analyses the morphological differences among 10 populations...

this study concerns the cytotaxonomic investigations on twelve species belonging to three sections from the genus vicia in iran. a taxonomic background of the genus is given in brief. the previous counts reported for the genus in index to plant chromosome number are summarized. in addition to one new count, the chromosome numbers of four species are reported for the first time. briefly, the res...

Resistance Gene Candidate2 (RGC2) genes belong to a large, highly duplicated family of nucleotide binding site-leucine rich repeat (NBS-LRR) encoding disease resistance genes located at a single locus in lettuce (Lactuca sativa). To investigate the genetic events occurring during the evolution of this locus, approximately 1.5- to 2-kb 3' fragments of 126 RGC2 genes from seven genotypes were seq...

among the recently collected chalcidoid wasps in a rice field of eastern guilan province (coast of caspian sea), in july 2012, there was a specimen of pteromalidae belonging to the genus callitula. it was identified as callitula ferrierei (bouček, 1964). both genus and species are new record for iranian fauna. morphological characters and geographical distribution of the newly recorded species ...

Previous studies based on morphological and molecular markers indicated that there are two cultivated and five wild rice species within the Oryza genus with the AA genome. In the cultivated rice species, Oryza sativa, a retroposon named p-SINE1 has been identified. Some of the p-SINE1 members characterized previously showed interspecific insertion polymorphisms in the species with the AA genome...

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...
