Phytoremediation uses plants for environmental cleanup. However, various shortcomings have prevented routine adoption and use of this technology by engineers. For the purposes of heavy metal extraction, one such shortcoming has involved insufficient

Flowing culture systems have been widely used in plant research to answer numerous questions involving plant nutrient requirements, cycles, and kinetics. Here, a flowing culture system was built in order to detect cadmium uptake in plants. Termed the

The aleurone layer of the developing rice (Oryza sativa L.) caryopsis is the first filial tissue in a position to take up sucrose released into the endosperm apoplast by the maternal nucellus. Adhesion of the aleurone layer to the nucellus during rip

The processes involved in rice (Oryza sativa L.) panicle ripening vary with time and topological grain position. Methods to describe the functioning and connectivity of the grains on a panicle could aid the analysis of these processes. Hence, we addr

Accurate simulation models for short-term (∼hours) changes in hydroponic crop growth and nitrate uptake are needed for rapid fault detection in hydroponic systems. Comparison between model-predicted and measured values for crop growth and nitrate u

The ripening rice (Oryza sativa L.) caryopsis contains several maternal and embryonic tissues that transport assimilates along the partitioning pathway. Experimental access to transport steps in the pathway is limited by the separability of the tissu

Plasma membranes were isolated using the aqueous polymer two-phase partition method from the algae Chara corallina and Chara longifolia, algae which differ in their ability to grow in saline environments. Enrichment of plasma membrane and depletion o

Maize (Zea mays L.) root plasma membranes purified by the aqueous polymer two-phase technique have previously been shown to be very low in tonoplast H + -ATPase and H + -PPase activities. Western blots of a similar preparation showed that, compared t

The nitrate (NO−3) uptake rates of intact, 23 day old rice plants were measured to determine the relationship between the plant's NO−3 nutrition history and the NO−3 uptake rate. A system for measuring NO−3 uptake was designed, built and test
