In the flora of Samara-Ulyanovsk Volga region, Brassicaceae family is one leading ones. It interest to study composition genera this at level territory entire as well physiographic regions included in it. helps understand whether there are local features cruciferous and what they are. Two natural zones distinguished area: forest-steppe steppe; four provinces 15 physical-geographic regions. pape...

after heavy rainfalls in late apr. of 2010 in tehran, an epizootic occurred amongst hoverflies (eupeodes corollae fabricius) population in green spaces of iranian research institute of plant protection, caused by an entomopathogenic fungus. infected flies fixed to the upper parts of whitetop (lepidium draba l.) and small tumbleweed mustard (sisymbrium loeslii l.) plants with their proboscis and...

The Brassica database (BRAD) was built initially to assist users apply Brassica rapa and Arabidopsis thaliana genomic data efficiently to their research. However, many Brassicaceae genomes have been sequenced and released after its construction. These genomes are rich resources for comparative genomics, gene annotation and functional evolutionary studies of Brassica crops. Therefore, we have up...

Reproductive genes and traits evolve rapidly in many organisms, including mollusks, algae, and primates. Previously we demonstrated that a family of glycine-rich pollen surface proteins (GRPs) from Arabidopsis thaliana and Brassica oleracea had diverged substantially, making identification of homologous genes impossible despite a separation of only 20 million years. Here we address the molecula...

The germination of seeds of Sisymbrium officinale is light- and nitrate dependent. A close interaction between the effects of light and nitrate on germination has been reported previously (HWM Hilhorst, CM Karssen [1988] Plant Physiol 86: 591-597). In this study, a detailed dose-response analysis of the light-induced germination during induction of secondary dormancy is presented. Germination i...

An experiment was conducted under controlled conditions to study the effect of water extract of leaves, shoots and roots of either Sisymbrium irio L. =SISIR and/or Descurainia sophia (L.) Schur =DESSO on the germination and primary growth of wheat. A split-split plot experiment in CRD with three replications was used. The main plots were the type of weed: i.e. SISIR and DESSO and the sub-plots ...

The discovery of antibiotics initiated the era drug innovation and implementation for human animal health. Very soon, antibiotic resistance started evolving due to over-prescription heavy usage drugs leading deleterious side effects. However, using plant extracts or medicinal plants has emerged as a new approach dealing with current problem. One such Sisymbrium irio L. is widely used in Unani t...
