Background and Aims DREB proteins are involved mainly in plant responses to abiotic stresses such as cold, drought or high salinity as well as ABA signalling. However, the function of most rice DREB genes and the underlying molecular mechanisms controlling these responses remains elusive. In this study, ARAG1, a rice DREB gene, was functionally analysed. Methods Antisense and over-expressio…
Abstract. Sodium montmorillonite (Na-MMT) was modified with various amounts of aminopropylisooctyl polyhedral oligomeric silsequioxane (POSS) and a second surfactant (alkyl ammonium based) via ionexchange reactions. Interlayer spacing, interlamellar structure, and thermal and surface properties of these organoclays were characterized by wide angle X-ray diffraction, thermogravimetric analys…
Abstract. In this work, we fabricated the composites containing multi-walled carbon nanotubes (MWNTs) and 4- methoxyphenyl-40-propylbenzoate (MPPB), a monotropic nematic liquid crystal (LC), via ultrasonication. The nematic phase and thermal stability of the resultant MWNTs/MPPB nanocomposites were investigated by polarized optical microscopy (POM) and thermogravimetric analyzer (TGA) respe…
