The subject invention provides novel plants that are not only resistant to 2,4-D and other phenoxy auxin herbicides, but also to aryloxyphenoxypropionate herbicides. Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. The subject invention also includes plants that produce one or more enzymes of the subject invention alone or “stacked” together with another herbicide resistance gene, preferably a glyphosate resistance gene, so as to provide broader and more robust weed control, increased treatment flexibility, and improved herbicide resistance management options. More specifically, preferred enzymes and genes for use according to the subject invention are referred to herein as AAD (aryloxyalkanoate dioxygenase) genes and proteins. No α-ketoglutarate-dependent dioxygenase enzyme has previously been reported to have the ability to degrade herbicides of different chemical classes and modes of action. This highly novel discovery is the basis of significant herbicide tolerant crop trait opportunities as well as development of selectable marker technology. The subject invention also includes related methods of controlling weeds. The subject invention enables novel combinations of herbicides to be used in new ways. Furthermore, the subject invention provides novel methods of preventing the formation of, and controlling, weeds that are resistant (or naturally more tolerant) to one or more herbicides such as glyphosate.

The present invention provides assays systems and methods for detection of chromosomal abnormalities and status of single loci associated with monogenic or polygenic traits in a sample containing nucleic acids from a maternal and a fetal source.

A method for detecting single copies of a gene in-situ using brightfield microscopy is used in detection of nucleic acid sequences. Probes are directly or indirectly labeled with alkaline phosphatase with NBT / BCIP used as the chromogen.

An inbred maize line, designated NP2460, seeds of inbred maize line NP2460, to plants of inbred maize line NP2460, to inbred maize line NP2460 into which one or more specific, single gene traits, for example, transgenes, have been transformed and / or introgressed.

The present invention provides assays systems and methods for detection of chromosomal abnormalities and status of single loci associated with monogenic or polygenic traits in a sample containing nucleic acids from a maternal and a fetal source.

The present invention relates to methods of treating ADAMTS-5-associated diseases and particularly osteoarthritis comprising administering an agent capable of modulating ADMATS-5 activity to a subject afflicted with the disease. The agent is preferably a biaryl sulfonamide compound. The invention is based, in part, on the discovery that transgenic animals that do not express functional ADAMTS-5 show a reduction in the degree of osteoarthritis after the induction of osteoarthritis as compared to WT animals. Furthermore, the ADAMTS-5 transgenic animals have reduced aggrecanase activity in articular tissue as compared to WT animals. These animals are good models for ADAMTS-5-associated diseases, and for screening of drugs useful in the treatment and / or prevention of these diseases. There are no other animal models in which the deletion of the activity of a single gene is capable of abrogating the course of osteoarthritis. Accordingly, these animals also show that osteoarthritis can be prevented and / or treated by administering to a subject an ADAMTS-5 inhibitory agent and particularly an agent capable of inhibiting the aggrecanase activity of ADAMTS-5.

Using crossbred segregating populations of two-rowed and six-rowed barley cultivars, the row type of individual plants was precisely determined. The results indicate that row type is controlled by a single gene. In addition, it was discovered that molecular markers linked with this gene could be used to identify whether a test barley or related Triticeae plant is two-rowed or six-rowed. Furthermore, molecular markers can be used to identify Fusarium head blight resistance, which is linked with the two-rowed or six-rowed gene.
