Scutellospora calospora (Nicol. & Gerd.) Walker & Sanders associated with subterranean clover: dynamics of colonization, sporulation and soluble carbohydrates

Growth model for arbuscular mycorrhizal fungi

In order to quantify the contribution of arbuscular mycorrhizal (AM) fungi to plant phosphorus nutrition, the development and extent of the external fungal mycelium and its nutrient uptake capacity are of particular importance. We develop and analyse a model of the growth of AM fungi associated with plant roots, suitable for describing mechanistically the effects of the fungi on solute uptake b...

Subterranean Clover Response to Recombined Ag Grade and Superfine Limestone

Soluble Carbohydrates in Soybean

Soybean seeds accumulate soluble carbohydrates throughout development and maturation. Soluble carbohydrates may have important roles in seed germination, seed desiccation tolerance, and cold stress tolerance. The analysis of soluble carbohydrates in soybean seeds and other plant parts at various growth stages (Obendorf et al., 1998b & 2009; Kosina et al., 2009), under environmental stresses (Bl...

Oestrogenic Activity of Subterranean Clover 2. THE ISOLATION OF GENISTEIN FROM SUBTERRANEAN CLOVER AND METHODS OF QUANTITATIVE ESTIMATION By D. H. CURNOW*

The isolation of small amounts of genistein (5:7:4'trihydroxy-isoflavone) from subterranean clover (Trifolium subterraneum var. Dwalganup) and the demonstration of its weakly oestrogenic properties (Bradbury & White, 1951, and Biggers & Curnow, 1954), together with the difficulties in the synthesis of this compound, made it important that a more efficient method be found for the isolation of th...

Extraction and analysis of soluble carbohydrates.

Soluble sugars are a universal component of most living organisms and a fundamental building block in biosynthetic processes. It is no wonder that both qualitative and quantitative changes in carbohydrates often accompany plant's responses to stress. Depending on the speed of onset of stress, plant tissues can exhibit rapid and very site-specific shifts in their soluble carbohydrate pool - rapi...
