A Simple Array Platform For Microrna Analysis And Its Application In Mouse Tissues, Xiaoqing Tang, Jozsef Gal, Xun Zhuang, Wang-Xia Wang, Haining Zhu, Guiliang Tang

Plant and Soil Sciences Faculty Publications

MicroRNAs (miRNAs) are a novel class of small noncoding RNAs that regulate gene expression at the post-transcriptional level and play a critical role in many important biological processes. Most miRNAs are conserved between humans and mice, which makes it possible to analyze their expressions with a set of selected array probes. Here, we report a simple array platform that can detect 553 nonredundant miRNAs encompassing the entire set of miRNAs for humans and mice. The platform features carefully selected and designed probes with optimized hybridization parameters. Potential cross-reaction between mature miRNAs and their precursors was investigated. The array platform was …


Evaluating P And K Fertilizer Prescriptions From Site-Specific Technologies, John H. Grove, E. M. Pena-Yewtukhiw Jan 2007

Evaluating P And K Fertilizer Prescriptions From Site-Specific Technologies, John H. Grove, E. M. Pena-Yewtukhiw

Soil Science News and Views

Developing a field's fertilizer prescription as a part of a site-specific nutrient management plan can be one of the more costly tasks undertaken. Those costs are traditionally associated with gathering of a number of plant and/or soil samples, their testing, as well as acquiring and applying amendments. Soil sample analysis is particularly important for traditional phosphorus (P), potassium (K) and soil acidity (pH) management. Soil sampling requires skill and time, time that may be in short supply when crop harvest is to be soon followed by establishment of a succeeding crop. Soil test results are not always timely, further delaying …


Effect Of Avail® Polymer Applied To Phosphorus Fertilizers On Dry Matter Production And P Uptake Of Fescue At Princeton, Ky, Lloyd W. Murdock, John James Olson, Gene Olson Jan 2007

Effect Of Avail® Polymer Applied To Phosphorus Fertilizers On Dry Matter Production And P Uptake Of Fescue At Princeton, Ky, Lloyd W. Murdock, John James Olson, Gene Olson

Soil Science News and Views

A study was conducted near Princeton, KY to determine if a polymer (AVAIL®) applied to diammonium phosphate (DAP, 18- 46-0) and mono ammonium phosphate (MAP, 11-52-0) would increase (P) phosphorus use efficiency in fescue production on a low P testing soil, when compared to an untreated phosphate fertilizer. AVAIL® (Specialty Fertilizer Products, Belton, MO) is presently being sold in Kentucky as a product to improve phosphorus fertilizer efficiency.


Groundwater Quality In Kentucky: Iron, R. Stephen Fisher, Bart Davidson Jan 2007

Groundwater Quality In Kentucky: Iron, R. Stephen Fisher, Bart Davidson

Information Circular--KGS

Iron is one of the most abundant elements in rocks and soils, and one of the most common problems in groundwater supplies. Rainwater seeping through soils and bedrock dissolves iron and carries it to wells and springs. In deep groundwater systems that lack oxygen, iron occurs as dissolved ferrous ion and the water is clear. Under oxidizing conditions such as in shallow groundwater systems or where the water is exposed to air at a tap or faucet, however, iron converts to a ferric form when it combines with oxygen to form reddish-brown rust particles. In addition to natural sources, elevated …


Groundwater Quality In Kentucky: Manganese, R. Stephen Fisher, Bart Davidson Jan 2007

Groundwater Quality In Kentucky: Manganese, R. Stephen Fisher, Bart Davidson

Information Circular--KGS

Manganese is a common constituent of Kentucky rocks and soils and, along with iron is one of the most widespread causes of problems in groundwater supplies. Rainwater seeping through soils and bedrock dissolves manganese and carries it in the groundwater system to wells and springs. In deep, slow-moving systems that lack oxygen, manganese remains in solution. Under oxidizing conditions, however, such as in shallow groundwater systems or where the water is exposed to air, manganese combines with oxygen to form black particles that can clog plumbing fixtures and stain containers and clothing.


Groundwater Quality In Kentucky: 2,4-D, Bart Davidson, R. Stephen Fisher Jan 2007

Groundwater Quality In Kentucky: 2,4-D, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

2,4-dichlorophenoxyacetic acid, commonly known as 2,4-D, is an herbicide used for selective control of broadleaf and grassy weeds in crops such as corn and wheat, along roadways and rights-of-way, and on pasture and rangeland. 2,4-D is the most widely used herbicide in the world, and the third most widely used in North America after metolachlor and atrazine. 2,4-D is a synthetic, organic, white to yellow, odorless, crystalline powder that dissolves readily in water. It is widely used today primarily because of its low cost.


Groundwater Quality In Kentucky: Atrazine, Bart Davidson, R. Stephen Fisher Jan 2007

Groundwater Quality In Kentucky: Atrazine, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Atrazine is an organic herbicide used for selective control of broadleaf and grassy weeds in crops such as corn, soybeans, sorghum, sugarcane, macadamia nuts, pineapples, pine trees, grasslands, and roses. Atrazine does not harm the crops, which can absorb and metabolize the herbicide, thereby removing the toxins. It controls targeted plants by inhibiting photosynthesis (Wilkes University Center for Environmental Quality, 2003). Atrazine is a white, odorless, crystalline powder that dissolves readily in water and does not occur naturally. It is widely used because of its low cost and ability to reduce crop losses from weed interference.
