SEED ROT CAUSED BY THE FUNGUS PYTHIUM ULTIMUM IS A MAJOR CAUSE OF CROP LOSS IN NORTHERN CLIMATES WHERE COOL PLANTING SEASONS ARE COMMON. SEEDS ARE GENERALLY TREATED WITH THE FUNGICIDES METALAXYL AND CAPTAN (BANNED IN GERMANY) TO PREVENT SEED ROT. A BIOTYPE OF THE BACTERIA PSEUDOMONAS AUREOFACIENS -- AB 254 -- HAS PERFORMED AS WELL AS METALAXYL IN PREVENTING SEED ROT FOR SWEET CORN AND BEETS, AND, ...

Enzymes used as the label for most non-radioactive assays and in biosensors, are the most unstable component of these systems. As immunoassays and biosensors move from the tightly controlled laboratory environment to demanding field conditions, the need for a more stable enzyme becomes critical. Alkaline phosphatase is the most widely used enzyme for these types of applications. A heat stable enzy ...

Chlorella virus (Cvi) restriction nucleases are a large, untapped source of gene mapping tools that have considerable commercial potential. Unlike bacterial restriction endonucleases, which recognize 4 to 8 base pair (bp) DNA target sequences, Cvi endonucleases define unique 2 to 4 bp cleavage sites and lend themselves to a variety of novel fine structure gene mapping applications. However, at the ...

The primary long term objective will be the large scale production of novel organometallic reagents prepared from highly reactive Rieke Metals. Primary metals to be examined include zinc, magnesium, copper, and calcium. The development of highly reactive Rieke Metals allows the direct oxidative addition of these metals to a variety of carbon-halogen bonds to yield many classes of organometallic re ...

A program is proposed to develop a commerical source for spectral hole burning materials and their properties. The proposed program will create a file of material and their properties for this application. A crystal growth program is proposed to grow Eu:Y2Si05, Pr:YA103, and Sm:CaW04.

Several laser designers have requested Scientific Materials Corporation (SM) to consider methods to achieve a cladding for Tm:YAG diode pumped laser rods. SM has looked at several mechanical methods and concluded mechanical systems are impractical. In the early 1960's the PI of this program developed techniques to grow overlays of sapphire on ruby. These rods were used to c-w pump ruby and they wo ...
