Successful implementation of vegetative buffers requires inclusion of plant species that facilitate rapid dissipation of deposited contaminants before they have a chance to be transported in surface runoff or to shallow groundwater. Thirty-six field lysimeters with six different ground covers [bare ground, orchardgrass (Dactylis Received 20 October 2005, Accepted 12 June 2006 Address correspond...

The plant secretome refers to the set of proteins secreted out of the plant cell into the surrounding extracellular space commonly referred to as the apoplast. Secreted proteins maintain cell structure and acts in signaling and are crucial for stress responses where they can interact with pathogen effectors and control the extracellular environment. Typically, secreted proteins contain an N-ter...

Plant metabolomics has matured and modern plant metabolomics has accelerated gene discoveries and the elucidation of a variety of plant natural product biosynthetic pathways. This review covers the approximate period of 2000 to 2014, and highlights specific examples of the discovery and characterization of novel genes and enzymes associated with the biosynthesis of natural products such as flav...

‎we call a ring $r$ right generalized semiperfect if every simple right $r$-module is an epimorphic image of a flat right $r$-module with small kernel‎, ‎that is‎, ‎every simple right $r$-module has a flat $b$-cover‎. ‎we give some properties of such rings along with examples‎. ‎we introduce flat strong covers as flat covers which are also flat $b$-covers and give characterizations of $a$-perfe...

Thin layer chromatography has been used for the analysis of natural and synthetic steroids in various environmental materials. In this work I steroid analysis in environmental materials such pharmaceuticals, plant products and other biological specimens. An overview of structural complexities and biological/nutritional aspects including hypocholesterolemic activities of phytosterols is provided...

MicroRNAs (miRNAs) and short interfering RNAs (siRNAs), 20to 27-nt in length, are essential regulatory molecules that act as sequence-specific guides in several processes in most eukaryotes (with the notable exception of the yeast Saccharomyces cerevisiae). These processes include DNA elimination, heterochromatin assembly, mRNA cleavage and translational repression. This review focuses on the r...

Abstract Objective: The current study summarizes the updated information concerning the ethnopharmacology, Phytochemistry, and pharmacology of Otostegia persica Boiss. (Lamiaceae), an endemic medicinal plant in south and southeast of Iran. Materials and Methods: Information was collected through bibliographic investigation from scientific journals, books, theses, reports, and electronic search ...

Plant cell walls are composites of various carbohydrates, proteins and other compounds. Cell walls provide plants with strength and protection, and also represent the most abundant source of renewable biomass. Despite the importance of plant cell walls, comparatively little is known about the identities of genes and functions of proteins involved in their biosynthesis. The model plant Arabidops...

The present work offers a review addressing the chemistry and pharmacology of Limnophila aromatica (Lamk.) Merr. (Belonging to Scrophulariaceae family) regarded as one of the most significant plant species in traditional system of medicine and is established as a source of flavonoids, terpenoids etc. The isolated phytochemicals as well as different extracts exhibited significant biological acti...
