in this research, dried acetone:chloroform extract of aerial parts of e. denticulata as one of the endemic plants to iran, afforded a number of triterpenes and steroids including: betulin, 24-methylene-cycloart-3-ol, cycloart-23z-ene-3β,25-diol, cycloart-23z-ene-3β,25-diol, ergosta-8,24-dien-3-ol (obtusifoliol) and beta-sitosterol which were reported for the first time from this plant. the stru...

The New World species of Dohrniphora lacking large hind tibial setae are revised, with 139 species recognized, most from the Neotropical Region. Of these, 88 are described as new to science. New synonymies are as follows: D. denticulata Borgmeier is a junior subjective synonym of D. penicillata Borgmeier, D. caverna Disney and D. recurvata Borgmeier are both junior subjective synonyms of D. div...

Three new eriophyid species (Phyllocoptinae), Shevtchenkella denticulata sp. n., Notallus pestehae sp. n. and Echinacrus ruthenicus sp. n., were described from Eryngium thyrsoideum Boiss. (Apiaceae), Pistacia vera L. (Anacardiaceae) and Lycium ruthenicum Murray (Solanaceae), respectively. All the three new species were collected from southwest of the East Azerbaijan province, Iran in 2011. It i...

The genus Tapiena (Orthoptera: Phaneropteridae: Phaneropterinae), consisting of species from around Asia and Africa, is reviewed. Henningian species concept was applied and morphology was used to estimate species boundaries. From Sakaerat Environmental Research Station, Thailand, two new species are described: Tapiena sakaerat Tan, Liu, Artchawakom sp. n. and Tapiena denticulata Tan, Liu, Artch...

The seeds of Medicago disciformis and Medicago turbinata contain lectins for T or Th but not Tk or Tx red cell cryptantigens. Extracts of Medicago disciformis seeds are a useful addition to a panel of lectins used in the classification of red cell cryptantigens and of red cell polyagglutinability.

Nodules are unique organs formed on roots of legumes by soil-borne bacteria, collectively known as rhizobium. Recently, we have shown that orthologs of the AINTEGUMENTA-like (AIL) AP2 transcription factors PLETHORA (PLT) 1 to 4, that redundantly regulate Arabidopsis thaliana root development are involved in root and nodule growth in Medicago truncatula. Hence, it is conceivable that rhizobium h...

We have identified an active Medicago truncatula copia-like retroelement called Medicago RetroElement1-1 (MERE1-1) as an insertion in the symbiotic NSP2 gene. MERE1-1 belongs to a low-copy-number family in the sequenced Medicago genome. These copies are highly related, but only three of them have a complete coding region and polymorphism exists between the long terminal repeats of these differe...
