In this investigation, analyses were made of the contents of hemicellulose, cellulose, crude lignin, crude protein and ash in 43 different plant materials. In addition, the proportions of various sugar anhydrides in the hemicellulose fraction were determined. The carbohydrate analyses were made by hydrolysing to monosaccharides, except for the uronic anhydrides, which were determined by the decarboxylation method. The sum of the cell-wall constituents thus determined was subsequently compared with Paloheimo’s membrane substances and crude fibre. Large variations in the cell-wall composition were found between different plant materials. Furthermore, there were large differences in the solubility of the cell-wall substances of different plant materials in the hydrolysing procedures used in determinations of membrane substances and crude fibre. The hemicellulose composition of different species in the same genus and even in the same family was found to be similar in definite plant parts and at definite growth stages. This appears to be a generic characteristic in the chemical taxonomy of plants.

Chitosan oligosaccharide (COS), derived through hydrolysis of chitosan, has been proved to be an effective plant immunity elicitor, eco-friendly, and easily soluble in water, and influenced several secondary metabolites content to improve fruit qualities. COS are widely used in agriculture to improve the defense response in plants. The purpose of this study was to investigate the pre-harvest treatment effect of COS on the quality of strawberry (Fragaria × ananassa cv.qingxiang). COS was dissolved in distilled water at a concentration of 50 mg·L−1 and sprayed at four different growth stages of strawberry plants, namely seedling stage, before flowering, fruit coloring (the stage of fruit from white to red) and full bloom. Uniform size, shape, color, without any visible damage, and disease-free fruits were harvested for determining the quality. The results showed that the fruit firmness, viscosity, lignin, sugars, protein, total soluble solid, and titratable acidity content increased in COS-treated fruits compared to control. In addition, COS pre-harvest treatment had a positive effect on anthocyanin, total phenol, flavonoid, vitamin C content and DPPH(2,2-diphenyl-1-picrylhydrazyl) scavenging activity of strawberry. Moreover, COS also increased the cell wall composition and regulated gene expression of some important enzymes involved in ethylene compound biosynthesis and cell wall degradation. The finding of this study suggests that pre-harvest application of COS is very useful for improving quality and antioxidant capacity of strawberry.

Resistant Cells

Mutation to viomycin-resistance in Rhizobium meliloti R21 resulted in an accumulation of phosphatidylcholine and phosphatidylethanolamine in the cell wall. Resistance to viomycin decreased when the excess lipid was removed by EDTA or when its synthesis was prevented by growth of normally resistant cells at 40 °C. Microelectrophoretic data showed binding of viomycin to the cell surface and it is proposed that the mechanism of resistance to viomycin is an immobilization of the antibiotic in the surface layers of the cell as a result of combination with phospholipid.
