Exposure of the mature Arabidopsis (Arabidopsis thaliana) seed to water results in the rapid release of pectinaceous mucilage from the outer cells of the testa. Once released, mucilage completely envelops the seed in a gel-like capsule. The physical force required to rupture the outer cell wall of the testa comes from the swelling of the mucilage as it expands rapidly following hydration. In th...

Trigonella persica is a valuable medicinal plant which comprises trigonelline that secondary metabolite and important component in cosmetic medicine. This research was conducted order to evaluation the drought stress effect on growth parameters, root anatomical changes content T. persica. Plants were grown under soil moisture corresponding 100%, 75%, 50% 25% field capacity for two weeks. The da...

Mucilage extracted from Plantago psyllium seeds was evaluated for inertness and safety parameters. The suitability of psyllium mucilage for a pharmaceutical binder was assessed in paracetamol tablets. Properties of the granules prepared using different concentrations of psyllium mucilage was compared with PVP and tragacanth. Psyllium mucilage at 5 % (m/m) was found to be comparable with 3 % (m/...

In some plant species, including Arabidopsis, fertilization induces the epidermal cells of the outer ovule integument to differentiate into a specialized seed coat cell type with a unique morphology and containing large quantities of polysaccharide mucilage (pectin). Such seed coat mucilage cells are necessary for neither viability nor germination under normal laboratory conditions. Thus, the A...

seed germination is the most sensitive growth stages of the plant to salinity stress. seeds of many species produce a jelly-like layer called mucilage upon exposure to water. the purpose of this study was to determine the role of mucilage in increasing salinity tolerance of lallemantia ibrica. seeds of this plantcontain mucilage that can be used to treat some diseases such as neurological, live...

The application of organic fertilizers alone or in combination with bio-fertilizers is important for sustainable agriculture, healthy agricultural production and restoring soil quality. Compost, vermicompost and mycorrhiza amendments could improve soil quality and plant yield. However, little is known about their impact on yield and quality of European borage (Borago officinalis L.). To evaluat...

THE recent observations of Klein & Linser [1932; 1933, 1, 2] on the betaines stachydrine and trigonelline in Stachys palustris and Trigonella Foenum-graecum point to the fact that these substances are intimately connected with protein metabolism. These workers showed that proline and ornithine when injected into the plant caused increases in the concentrations of stachydrine and trigonelline. O...

The Arabidopsis seed coat epidermis undergoes a complex process of differentiation that includes the biosynthesis and secretion of large quantities of pectinaceous mucilage, cytoplasmic rearrangement, and secondary cell wall biosynthesis. Mutations in MUM4 (MUCILAGE-MODIFIED4) lead to a decrease in seed coat mucilage and incomplete cytoplasmic rearrangement. We show that MUM4 encodes a putative...
