Managing the continuous corn yield penalty with crop and residue management
… two research areas: What are the effects of hybrid selection, enhanced fertility, and population on corn yield and can these factors reduce the CCYP? Enhanced fertility improved grain yield across rotations and there was a 40 to 60% greater yield response to intensive management in continuous …

A two-color bacterial two-hybrid system for selecting sequence-specific DNA-binding proteins via fluorescence activated cell sorting
… (starting with a pre-existing bacterial two-hybrid selection system) which allows the selection of proteins based on their preference of one DNA site over another. I use this system to attempt to attenuate the affinity of a zinc finger protein without destroying its specificity. Finally, I …

Aptamers that bind filovirus GP : a new frontier for detection and neutralization of Ebola and Marburg virus
… They are made through an in vitro combinatorial selection method, wherein large libraries of nucleic acids with randomized sequences are subjected to an iterative process of affinity enrichment, partitioning, and amplification. Evolved libraries are sequenced, and the individual sequences are …

Phase-locked loop, delay-locked loop, and linear decorrelating detector for asynchronous multirate DS-CDMA system
… an implementation scheme. Therefore, we propose Hybrid Selection Diversity/ Maximal Ratio Combining (Hybrid SD/MRC) one-shot window linear decorrelating detector (LDD) for asynchronous DS-CDMA systems. The selection diversity scheme at the input of the Hybrid SD/MRC LDD is based on choosing the …

Innovative foliar micronutrient sources in high-yielding corn environments
… grain-filling. Increased planting densities and hybrid selection create a high-yield potential in today's modern corn production systems, necessitating greater nutrient supply or efficiency. Limited plant remobilization and translocation of Zn requires greater root accumulation of Zn. …

Optimizing Zinc Finger Nucleases for Use in Mammalian Cells
… strategies: modular assembly and a bacterial 2-hybrid selection strategy. We have found that ZFNs made by the bacterial 2-hybrid strategy are both more efficient at stimulating gene targeting and less toxic than ZFNs made by modular assembly. We have also found that ZFNs made via the bacterial …

The mRNA Cap and Discontinuous Transcription in Trypansoma brucei
… vivo <sup>32</sup>P-labeled RNA was purified by hybrid selection with mini-exon genomic DNA, in order to analyze the structure of medRNA, the 140- nucleotide precursor of the mini-exon in mRNA. Some possible intermediates in the joining reaction and the 5' mini-exon cap structure were detected …

Optimizing Foramsulfuron for Weed Control and Corn Tolerance
… used as the adjuvant. However, this adjuvant selection did not improve control of woolly cupgrass. Foramsulfuron is formulated with a crop safener, isoxadifen-ethyl, to enhance corn tolerance. Field, greenhouse, and laboratory studies were conducted to determine what effect this safener had on …

Management of higher populations in maize
… grain yield and yield components. One commercial hybrid (DKC 61-21 SSTX) was grown in two row configurations (single or twin) at different plant density levels (86, 99, 111, 124, 136 and 161 plants ha-1 x 1,000). MESZ (MicroEssentials SZ) was banded within the row at planting at one of the …

Characterization and management of major fungal diseases and mycotoxin contamination of grain sorghum in the mid-Atlantic U.S.
… anthracnose, (2) compare five grain sorghum hybrids for their susceptibility to foliar anthracnose, grain mold and mycotoxin contamination under field conditions, (3) integrate host resistance and fungicide application to manage anthracnose and grain mold, and (4) identify Fusarium spp. …

Agronomic management to improve corn productivity under high-yielding environments
… a corn grower makes today are: 1) which hybrid to plant, 2) what population to plant, and 3) what nitrogen (N) program to use. Hybrid selection is a critical management decision made by farmers because for any given year the spread in grain yield among current commercial hybrids that year …
