Betaine accumulation and betaine-aldehyde dehydrogenase in spinach leaves.
Spinach leaf discs accumulated betaine when exposed to a mannitol solution of -20 bars. The accumulation was 12 micromoles per gram original fresh weight in a 24-hour period.Betaine-aldehyde dehydrogenase (EC 1.2.1.8) was assayed in various subcellular fractions prepared from spinach leaves, and it was found only in the soluble fraction. This cytosolic enzyme was purified 175-fold, and its prop...
متن کاملFunctional and expression analyses of two kinds of betaine aldehyde dehydrogenases in a glycinebetaine-hyperaccumulating graminaceous halophyte, Leymus chinensis
Glycinebetaine (GB) is an important compatible solute for salinity tolerance in many plants. In this study, we analyzed the enzymatic activity and the expression level of betaine aldehyde dehydrogenase (BADH), an important enzyme that catalyzes the last step in the GB synthesis in Leymus chinensis, a GB-hyperaccumulating graminaceous halophyte, and compared with those of barley, a graminaceous ...
متن کاملPlastid-expressed betaine aldehyde dehydrogenase gene in carrot cultured cells, roots, and leaves confers enhanced salt tolerance.
Salinity is one of the major factors that limits geographical distribution of plants and adversely affects crop productivity and quality. We report here high-level expression of betaine aldehyde dehydrogenase (BADH) in cultured cells, roots, and leaves of carrot (Daucus carota) via plastid genetic engineering. Homoplasmic transgenic plants exhibiting high levels of salt tolerance were regenerat...
متن کاملExpression of Aldehyde Dehydrogenase 1 in Patients with Colorectal Cancer in North of Iran
Background and purpose: High cancer related mortality can be due to the presence of cancer stem cells (CSCs). Studies suggest aldehyde dehydrogenase (ALDH1) as a marker of CSCs. The aim of this study was to investigate its expression in colorectal cancer and also its association with clinicopathologic characteristics. Materials and methods: In a retrospective study, patients with colorectal ca...
متن کاملArabidopsis aldehyde dehydrogenase 10 family members confer salt tolerance through putrescine-derived 4-aminobutyrate (GABA) production
Polyamines represent a potential source of 4-aminobutyrate (GABA) in plants exposed to abiotic stress. Terminal catabolism of putrescine in Arabidopsis thaliana involves amine oxidase and the production of 4-aminobutanal, which is a substrate for NAD+-dependent aminoaldehyde dehydrogenase (AMADH). Here, two AMADH homologs were chosen (AtALDH10A8 and AtALDH10A9) as candidates for encoding 4-amin...
