S-index and soybean root growth in different soil textural classes

A Case Study of Petroleum Degradation in Different Soil Textural Classes.

BACKGROUND Patents have been granted for a number of techniques for petroleum biodegradation including use of micro-organisms for degradation of hydrocarbon-based substances and for hydrocarbon degradation in oil reservoirs, but there is a dearth of information on hydrocarbon degradation in different soil textures. OBJECTIVE Hence, this work investigated the effects of different soil textures...

Physiological roles of glutathione s-transferases in soybean root nodules.

Glutathione S-transferases (GSTs) are ubiquitous enzymes that catalyze the conjugation of toxic xenobiotics and oxidatively produced compounds to reduced glutathione, which facilitates their metabolism, sequestration, or removal. We report here that soybean (Glycine max) root nodules contain at least 14 forms of GST, with GST9 being most prevalent, as measured by both real-time reverse transcri...

Scaling of Infiltration and Redistribution of Water across Soil Textural Classes

known (Tillotson and Nielsen, 1984): (1) the dimensional analysis technique, which is based on the existence of Results with an empirically based one-parameter model showed physical similarity in the system; and (2) the empirical that the pore-size distribution index ( ) described in the Brooks and Corey formulation of soil hydraulic properties can scale the soil–water method, called functional...

Root Interactions in a Maize/Soybean Intercropping System Control Soybean Soil-Borne Disease, Red Crown Rot

BACKGROUND Within-field multiple crop species intercropping is well documented and used for disease control, but the underlying mechanisms are still unclear. As roots are the primary organ for perceiving signals in the soil from neighboring plants, root behavior may play an important role in soil-borne disease control. PRINCIPAL FINDINGS In two years of field experiments, maize/soybean interc...
