Portulaca oleracea L. is a medicinal plant find in Europe and Asia. This plant contains valuable secondary metabolite such as noradrenalin. Naturally the wild plant produce small amount of this secondary metabolites so induction of hairy roots can be useful to increase its production. In our research Agrobacterium rhizogenes strain AR15834 was used to induce hairy roots in the two-week leaf exp...
Studying the biochemical responses of different plant species to insect herbivory may help improve our understanding of the evolution of defensive metabolites found in host plants and their role in plant-herbivore interactions. Untargeted metabolic fingerprints measured as individual mass features were used to compare metabolite reactions in three Brassicales host-plant species (Cleome spinosa,...
The environmental and financial costs of using inorganic phosphate fertilizers to maintain crop yield and quality are high. Breeding crops that acquire and use phosphorus (P) more efficiently could reduce these costs. The variation in shoot P concentration (shoot-P) and various measures of P use efficiency (PUE) were quantified among 355 Brassica oleracea L. accessions, 74 current commercial cu...
Plants, as sessile organisms, can suffer serious growth and developmental consequences under cold stress conditions. Glutathione transferases (GSTs, EC 2.5.1.18) are ubiquitous and multifunctional conjugating proteins, which play a major role in stress responses by preventing oxidative damage by reactive oxygen species (ROS). Currently, understanding of their function(s) during different bioche...

گیاه خرفه (portulaca oleracea l.) متعلق به تیره portulacaceae، عموماً به عنوان علف هرز شناخته شده و از نقطه نظر فیزیولوژیکی دارای قابلیت تحمل پذیری بسیار بالا در محیط های شور یا آلوده به فلزات سنگین بوده و گیاه مناسبی جهت کاشت و پالایش محیط و خاک از این گونه تنش ها به شمار می رود. به منظور نشان دادن اثرات دو فلز سنگین سرب و مس بر مالون دآلدهید، پرولین و آنزیم های آنتی اکسیدان آزمایشهایی در طرحی ...
Recently, 6-(2-naphthyl)-2, 3-dihydro-as-triazine-3-thione (NDTT) was synthesized in laboratory and used successfully for the spectrophotometric determination of nanogram levels of Cu(2+) in aqueous solution. This reagent forms a specific red complex with Cu(2+) ions after the extraction by chloroform at alkaline pH. The absorption of the complex in the UV region (313 nm) is about 8 times as st...
In recent decades, several canonical serine protease inhibitor families have been classified and characterized. In contrast to most trypsin inhibitors, those from garden four o'clock (Mirabilis jalapa) and spinach (Spinacia oleracea) do not share sequence similarity and have been proposed to form the new Mirabilis serine protease inhibitor family. These 30-40-amino-acid inhibitors possess a def...
In Brassica, the recognition of self-related pollen by the stigma is controlled by the highly polymorphic S locus that encodes several linked and coadapted genes and can span several hundred kilobases. We used pulsed-field gel electrophoresis to analyze the structure of different S haplotypes. We show that the S2 and S13 haplotypes of Brassica oleracea contain extensive sequence divergence and ...
Polyploidization has provided much genetic variation for plant adaptive evolution, but the mechanisms by which the molecular evolution of polyploid genomes establishes genetic architecture underlying species differentiation are unclear. Brassica is an ideal model to increase knowledge of polyploid evolution. Here we describe a draft genome sequence of Brassica oleracea, comparing it with that o...
