The rhizosphere is complex and heterogeneous. It contains exudates, lysates, mucilage, secretions, dead cell material and carbon dioxide all of which affect substrate flow to the root (Lynch and Whipps, 1991). Moreover, certain soil micro-... 

The mucilage secreted by bulbs can also produce harmful effects in plant species such as rose, rice, and cabbage, inhibiting seed germination and seedling growth (120,407).

Mucilage has protective functions for the root meristem and improves root-soil contact by inclusion and aggregation of soil particles. It may also contribute to P desorption and to the exclusion of toxic elements (Al, Cd, Pb) by complexation with galacturonates, mainly in exchange with Ca2+ (Neumann and Romheld, 2002). Secreted enzymes contribute to the extracellular enzyme pool it has been shown that the activity of extracellular enzymes, such as phophatases, proteases, and aryl-sulfatases, exhibit more activity in the rhizosphere relative to the bulk soil and may have a dramatic effect on the cycling of nutrients such as P, N, and S (Badalucco and Nannipieri, 2007). 

Plant roots stabilize bioavailable soil metal fractions through several mechanisms. Precipitation at the rhizosphere of the solubilized fraction of heavy metals in the soil is the primary mechanism of most metal adsorption to root surfaces (Blaylock et al., 1997). Adsorption also occurs through the binding of free metal cations by pectins on root cell walls and in pectin and other polysaccharide combinations from root-secreted mucilage (Waisel et al., 1996). 

The level of IL-4 in the spleen did not change after the same treatment. Instead, in the liver the oral administration of polysaccharides stimulated the secretion of both IFN-y and IL-4 at a dose of 200 mg/kg, together with a significant proliferation of hepatocytes [63]. Polysaccharide extracted from mucilage of D. huoshanense exhibited an effect in murine splenocytes. It induced the production of several cytokines, including IFN-y, IL-10, IL-6, and IL-la, and hematopoietic growth factors GM-CSF and G-CSF in mice splenocytes [64]. Further experiments were performed in mice and human cells in-vitro on polysaccharides isolated from D. huoshanense to point up the potentiality of these biopolymers in a therapeutic approach to some immime disease [65],...
