This study was designed to investigate the inoculation effects of P. fluorescens FY 32 on the growth of canola spring cultivars under drought stress. A factorial-split plot design in completely randomized blocks with three replications was conducted in hydroponic cultivation system. Six canola cultivars, including Hyola 308, Sarigol, RGS 003, Amica, Hyola 420 and Olga were inoculated with P. fluorescens FY 32 or left non-inoculated as control. Three levels of drought stress (control, 70 and 50% FC) were applied to the hydroponic cultivation system. Drought stress significantly reduced relative water content (RWC), leaf area, shoot height, root length and soluble sugar but augmented chl a and total chl content and the total proline. Our results showed that bacterial inoculation had a positive effect in reducing the deleterious effects of drought stress in some cases.

It is the process by which a protein structure assumes its functional shape or conformation. Proteins are comprised of amino acids with various types of side chains, which may be hydrophobic, hydrophilic or electrically charged. It is now well known that under physiological conditions, proteins normally spontaneously fold into their native conformations but there are some exterior factors which help polypeptide chain finding its natural shape. Different levels of folding a protein after amino acid sequence or primary structure consist of secondary, tertiary and quaternary structures. Protein folding pathway or mechanism is the typical sequence of structural changes; in which protein find its native structure. 3D structure of proteins is studied by scientists using different methods and there are many types of software to survey this. Many factors control protein folding, interior and exterior factors. Creation of natural folded proteins by these factors and protein translation are simultaneous. The main objective of this review is to unveil the fact; despite there are many factors controlling protein folding, mainspring is amino acids sequence which itself rises from chemo-physical laws.

Different protein expression systems have been used for the expression of recombinant proteins in which each of them face obstacles that make utilizing them as comprehensive expression system in order to express wide variety of proteins difficult. Plant cell as a eukaryotic expression system have many advantages compared to other hosts. They are very “safe” and significantly decrease concerns about the contamination of recombinant proteins with human pathogens. In addition to this, plants as eukaryotic expression system perform proper post-translational modification, in case of eukaryotic proteins, and appropriate folding resulting in right function in biological environments. Therefore, the production of pharmaceutical protein through plant cells can be absolutely promising approach. In this review, the production of pharmaceutical protein ...

Despite many canola varieties being described as 'salt-tolerant', plant yield and growth decline drastically with increasing salinity. Although many studies have resulted in better understanding of the many important salt-response mechanisms that control salt signaling in plants, detoxification of ions, and synthesis of protective metabolites, the engineering of salt-tolerant crops has only progressed slowly. Genetic engineering has been considered as an efficient method for improving the salt tolerance of canola but there are many unknown or little-known aspects regarding canola response to salinity stress at the cellular and molecular level. In order to develop highly salt-tolerant canola, it is essential to improve knowledge of the salt-tolerance mechanisms, especially the key components of the plant salt-response network. In this review, we focus on studies of the molecular response of canola to salinity to unravel the different pieces of the salt response puzzle. The paper includes a comprehensive review of the latest studies, particularly of proteomic and transcriptomic analysis, including the most recently identified canola tolerance components under salt stress, and suggests what researchers should focus on in future studies.
