Pollination triggers not only embryo development but also the differentiation of the ovule integuments to form a specialized seed coat. The mucilage secretory cells of the Arabidopsis thaliana seed coat undergo a complex differentiation process in which cell growth is followed by the synthesis and secretion of pectinaceous mucilage. A number of genes have been identified affecting mucilage secr...

During differentiation, the Arabidopsis seed coat epidermal cells synthesize and secrete large quantities of pectinaceous mucilage into the apoplast, which is then released to encapsulate the seed upon imbibition. In this study, we showed that mutation in Irregular Xylem 14 (IRX14) led to a mucilage cohesiveness defect due to a reduced xylan content. Expression of IRX14 was detected specificall...

introduction: nitrogen is an essential element forplants and in combination withelements such as carbon, oxygen, hydrogen and sulfur results ineven more valuable materials such as amino acids, nucleic acids, alkaloids. hibiscus tea (hibiscus sabdariffa ) from malvaceaefamily is known by different names in different parts of the world. in iran it is calledthe maki tea, tea meccaorred tea.as an i...

The rhizosphere is one of the major components in soil–plant–atmosphere continuum which controls flow water from soil into roots. Plant roots release mucilage capable altering physio-chemical properties this region. Here, we showed how impacted on hydraulic properties, using simple experiments. An artificial rhizosphere, treated or not with mucilage, was placed a sample and suction applied to m...

IN comparison with the immense bibliographies of starch and cellulose for example, the literature of the gums and mucilages is scanty. This, doubtless, is due in part to the great commercial importance of the former, but a contributory cause may be sought in the practical difficulties involved in dealing with the latter. The gums Und mucilages are complex colloids which are not infrequently fou...

Polysaccharide mucilage derived from the seeds of Plantago major L. (family Plantaginaceae) was investigated for use in matrix formulations containing propranolol hydrochloride. HPMC K4M and tragacanth were used as standards for comparison. The hardness, tensile strength, and friability of tablets increased as the concentration of mucilage increased, indicating good compactibility of mucilage p...

Seed coat development in Arabidopsis thaliana involves a complex pathway where cells of the outer integument differentiate into a highly specialized cell type after fertilization. One aspect of this developmental process involves the secretion of a large amount of pectinaceous mucilage into the apoplast. When the mature seed coat is exposed to water, this mucilage expands to break the primary c...

Summary The aim of the article was to obtain maximum information about plant mucilage, its sources and applications in pharmaceutical industry. This study focuses on scientific articles books available Internet resources college library that deal with sources, applications, extraction isolation mucilage. Mucilage is obtained mainly from can be isolated easily. Due low cost, easy availability, n...

Cellulose synthase5 (CESA5) synthesizes cellulose necessary for seed mucilage adherence to seed coat epidermal cells of Arabidopsis (Arabidopsis thaliana). The involvement of additional CESA proteins in this process and details concerning the manner in which cellulose is deposited in the mucilage pocket are unknown. Here, we show that both CESA3 and CESA10 are highly expressed in this cell type...

The preliminary phytochemical analysis of Limonia acidissima plant parts such as bark, leaf, rind, pulp and seed showed the presence of alkaloids, flavonoids, steroids, saponins, glycosides, phenols, gum and mucilage, fixed oils and fats, resins and tannins. Among the five plant parts, pulp possessed high amount of protein and the carbohydrate content was more in seeds and rind is rich was amin...
