Nitrate Use Efficiency In Tobacco Plants Constitutively Expressing A Maize Nitrate Transporter ZmNRT2.1

Nitrate Use Efficiency In Tobacco Plants Constitutively Expressing A Maize Nitrate Transporter ZmNRT2.1.
Creator
Cruz, Jessica, Zhang, Xing-Hai, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
The NRT2 (high affinity nitrate transporter 2) family is a part of the iHATS (inducible high affinity system) that studies have shown is responsible for the influx of nitrate into the plant cell after provision of nitrate. The ZmNRT2.1 from Zea mays was constitutively expressed in Nicotiana tabacum. To assess how over-expression of this foreign NRT2.1 affects nitrate influx by plants, nitrate content in leaf and root tissue, gene expression, and vegetal growth were analyzed in media with...
Show moreThe NRT2 (high affinity nitrate transporter 2) family is a part of the iHATS (inducible high affinity system) that studies have shown is responsible for the influx of nitrate into the plant cell after provision of nitrate. The ZmNRT2.1 from Zea mays was constitutively expressed in Nicotiana tabacum. To assess how over-expression of this foreign NRT2.1 affects nitrate influx by plants, nitrate content in leaf and root tissue, gene expression, and vegetal growth were analyzed in media with deficient or high nitrate concentrations (0.1, 1, or 10 mM). Compared to wild type plants: the transgenic lines had a significantly larger fresh weight in all nitrate conditions; primary root length was significantly longer in the 0.1 and 1 mM nitrate conditions; both the fresh weight and the primary root length were significantly higher when 50 mM NaCl was applied as a stress factor to medias containing 0.1 and 10 mM nitrate.

Does residential landscape type affect nitrogen runoff and leaching?
Title
Does residential landscape type affect nitrogen runoff and leaching?.
Creator
Erickson, John Erickson., Florida Atlantic University, Volin, John C.
Abstract/Description
Intensely maintained turfgrass landscapes have some potential for loss of fertilizer nitrogen (N) in both runoff and leaching. Lower maintenance vegetation used in mixed-species landscapes may reduce N leaching and runoff, which is important for reducing environmental pollution of surface and ground waters. However, few studies have examined this paradigm. Therefore, we constructed a field-scale facility to compare fertilizer N runoff and leaching between St. Augustinegrass (Stenotaphrum...
Show moreIntensely maintained turfgrass landscapes have some potential for loss of fertilizer nitrogen (N) in both runoff and leaching. Lower maintenance vegetation used in mixed-species landscapes may reduce N leaching and runoff, which is important for reducing environmental pollution of surface and ground waters. However, few studies have examined this paradigm. Therefore, we constructed a field-scale facility to compare fertilizer N runoff and leaching between St. Augustinegrass (Stenotaphrum secundatum (Walt.) Kuntze cv. 'Floratam') and a mixed-species landscape designed by the Florida Yards and Neighborhoods (FYN) program. A blended granular fertilizer was applied at a rate of 300 and 150 kg N ha-1 yr -1 on the turfgrass and mixed-species, respectively. During the 12-month study only one minor runoff event occurred (<0.2 cm) and N losses were insignificant. Annual N leaching losses were significantly greater on the mixed-species landscape, resulting in 4.80 g N m-2 compared to 0.41 g N m-2 for the St. Augustinegrass.
