Colonization of arbuscular-mycorrhizal fungi on Ri T-DNA transformed roots in synthetic medium.
Hairy root culture of tomato (Lycopersicon esculantum L.) was induced with three strains of Agrobacterium rhizogenes namely A4, ATCC 15834 and LBA 9402. The best response in terms of growth of hairy root was observed with A. rhizogenes strain A4 and LBA 9402 followed by ATCC 15834. Hairy roots were maintained on Murashige and Skoog (MS) medium but it could also grow on minimal (M) medium. Spore...
متن کاملQuantitative and qualitative effects of phosphorus on extracts and exudates of sudangrass roots in relation to vesicular-arbuscular mycorrhiza formation.
A comparison was made of water-soluble root exudates and extracts of Sorghum vulgare Pers. grown under two levels of P nutrition. An increase in P nutrition significantly decreased the concentration of carbohydrates, carboxylic acids, and amino acids in exudates, and decreased the concentration of carboxylic acids in extracts. Higher P did not affect the relative proportions of specific carboxy...
متن کاملInvestigation of Early Events in Fc RI-Mediated Signaling Using a Detailed Mathematical Model
Aggregation of Fc RI on mast cells and basophils leads to autophosphorylation and increased activity of the cytosolic protein tyrosine kinase Syk. We investigated the roles of the Src kinase Lyn, the immunoreceptor tyrosine-based activation motifs (ITAMs) on the and subunits of Fc RI, and Syk itself in the activation of Syk. Our approach was to build a detailed mathematical model of reactions i...
متن کاملExpression of plant genes for arbuscular mycorrhiza-inducible phosphate transporters and fungal vesicle formation in sorghum, barley, and wheat roots.
Sorghum shows strong growth stimulation on arbuscular mycorrhizal (AM) symbiosis, while barley and wheat show growth depression. We identified the AM-inducible phosphate transporter genes of these cereals. Their protein products play major roles in phosphate absorption from arbuscules, intracellular fungal structures. Unexpectedly, barley and wheat expressed the AM-inducible genes at high level...
متن کاملCase Report: Formation of Median Nerve by Three Roots
Atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. The present report describes a case of variation of the median nerve observed in the Iranian male cadaver during routine trial dissection. There are three roots for median nerve. Median nerve is formed by joining two lateral and medial cords of brachial plexus. Third root ...
