“…This is the first report on the slime structure of Matricaria. The staining results correspond to already published data in Artemisia and Eragrostis (BRODA 1971, GERLACH 1972, BRAUNE et al 1975, O' BRIEN and MCCULLY 1981, KREITSCHITZ and VALLÈS 2007, KREITSCHITZ et. al.…”

“…In the literature, the presence of slime has been reported for many other angiosperm genera, e.g. in Brassica, Salvia, Plantago, Linum, Anthemis, Artemisia and Matricaria (MUHLETHALER 1950, YOUNG and EVANS 1973, GRUBERT 1974, GRUBERT 1982, KREITSCHITZ and VALLÈS 2007. The cells producing slime could be arranged in isolated rows on the fruit surface, as in Anthemis, Artemisia and Matricaria (GRUBERT 1974).…”

“…It plays an important role in the control of germination, mostly in plants that grow in conditions of water deficiency in arid and semiarid environments, thus facilitating intake and maintenance of the water (KREITSCHITZ and VALLÈS 2007). Furthermore, it can delay germination due to impeded penetration by oxygen.…”

“…In some particular cases, production of slime on the fruit and or seed surface may also be an adaptation to ruderal, disturbed environments EVANS 1973, KREITSCHITZ andVALLÈS 2007). The presence of a slime envelope is associated with a short life cycle and facilitates the quick colonization of such places (KREITSCHITZ and VALLÈS 2007).…”

IntroductionAn important and relatively large genus in the flora of Turkey, Centaurea L. comprises ca. 250 species, currently distributed over Eurasia, especially in Irano-Turanian and Mediterranean regions (Anderberg et al., 2007). Centaurea has one of the highest rates of endemism in Turkey, with 112 endemics among 181 total species, 18 endemics among 32 subspecies, and 16 of the 28 varieties (Uysal, 2012). The genus Centaurea has been subjected to morphological, palynological, and cytotaxonomic studies for a very long time by several experts (

New Insights into the Composition and Structure of Seed Mucilage

Upon exposure to aqueous environments, polysaccharides present in the seed coats of myxospermous species swell and extrude forming a halo of mucilage that completely envelops the seed. The extruded mucilage is usually a composite of pectic, non‐cellulosic, and cellulosic polysaccharides, and because of its accessibility the seed mucilage system has been used extensively in the laboratory to uncover molecular mechanisms associated with plant cell wall (PCW) polysaccharide biosynthesis. The mucilage of Arabidopsis , which is predominantly composed of pectic polysaccharides, is the most extensively characterised. Interrogation of this system has revealed intricate molecular and chemical details about polysaccharide biosynthesis and seed coat development, clearly demonstrating the effectiveness of using seed mucilage systems as a proxy to study PCW polysaccharide biosynthesis. Significant advances have been made in our understanding and identification of the genes and enzymes involved in pectin, cellulose, and xylan biosynthesis. Recent results regarding the composition, combined with the definition of the architectural properties, of extruded seed mucilage are synergistic with our current models of how polysaccharides interact in the PCW. In addition to the desirable characteristics of myxospermy for the study of PCW polysaccharide biosynthesis, industrial applications of seed mucilages are extensive. Strong interest from the food manufacturing and processing, pharmaceutical, cosmetic, and waste management industries has also encouraged researchers to investigate the physiochemical properties of seed mucilages and their possible applications. This article highlights the recent advances made in our understanding of the molecular mechanisms and the architectural properties of mucilage biosynthesis across diverse species.
