Arabidopsis seed coat epidermal cells produce a large quantity of mucilage that is extruded upon exposure to water. Chemical analyses and cell biological techniques suggest that this mucilage represents a specialized type of secondary cell wall composed primarily of pectin with lesser amounts of cellulose and xyloglucan. Once extruded, the mucilage capsule has a distinctive structure with an ou...

In this study the rheological and textural properties of Iranian white cheese produced by ultrafiltration technique containing gum tragacanth and xanthan gum each in the range of 0-0.1%, and basil seed and linseed mucilages each in the range of 0-0.2% were evaluated. According to the results obtained, values of Elastic (G/) and viscous (G//) moduli increased with increasing frequency sweep in a...

s Decennial Index (1937—1946), references to polysaccharide chemistry covered 2 pages, i.e., about 480 references. References to starch covered five pages (1200 references), and those to cellulose and its derivatives, 20 pages (4800 references). A total of 6480 references, including patents, in a ten year period. During 1947—1956 references to polysaccharides covered 6 pages, i.e. 1360 referenc...

The immunostimulating activities of mucilage fraction from yam were investigated. The proliferation of BSA-primed lymph node cells was enhanced between 4.1- to 10.9-fold compare to control, when cultured with 1 to 25 microg/mL of yam-mucilage fraction. It showed strong immunopotentiating activity than ginseng extract and as remarkable as Bifidobacterium adolescentis M101-4 known as a positive i...

The Arabidopsis thaliana MYB5 gene is expressed in trichomes and seeds, including the seed coat. Constitutive expression of MYB5 resulted in the formation of more small trichomes and ectopic trichomes and a reduction in total leaf trichome numbers and branching. A myb5 mutant displayed minimal changes in trichome morphology, while a myb23 mutant produced increased numbers of small trichomes and...

OBJECTIVES Cucurbita moschata Duchesne (pumpkin) is a well-known plant with several pharmacological effects. The aim of the present study was to assess burn wound healing activity of C. moschata peel extract (CE). Also, standardized CE was assessed for antioxidant activity and antibacterial effects against major pathogens of burns. MATERIALS AND METHODS Healing properties of topical preparati...

Pectins are major components of plant primary cell walls. They include homogalacturonans (HGs), which are the most abundant pectin and can be the target of apoplastic enzymes like pectin methylesterases (PMEs) that control their methylesterification level. Several PMEs are expressed in the seed coat of Arabidopsis thaliana, particularly in mucilage secretory cells (MSCs). On the basis of public...

The objective of this study was to test the hypothesis that root of maguey (Agave salmiana Otto ex Salm-Dyck) seedlings reacts during the first 24 h to low substrate water potential (PsiW), by anatomical modifications. Three-4 cm root length seedlings were planted in vermiculite for 24 h at PsiW between -0.03 and -2.35 MPa. Root dimensions, proline content and anatomy were evaluated. Substrate ...

The genus Abutilon (Malvaceae) comprises about 150 species which are perennial herbs, shrubs and rarely small trees, distributed in sub-tropical regions of all over the world. Generally, Abutilon species contain considerable amounts of mucilage due to which they are used for the treatment of rheumatism and as demulcent and diuretic agents [1 – 3]. One of the species of the genus Abutilon is Abu...
