Compositions and methods comprising polynucleotides and polypeptides having glyphosate-N-acetyltransferase (GLYAT) activity are provided. In specific embodiments, the sequence has an improved property, such as, but not limited to, an improved specificity for glyphosate when compared to an appropriate control resulting in decreased off target acetylation of, e.g. an amino acid such as aspartate. Further provided are nucleic acid constructs, plants, plant cells, explants, seeds and grain having the GLYAT sequences. Various methods of employing the GLYAT sequences are provided. Such methods include methods for producing a glyphosate tolerant plant, plant cell, explant or seed and methods of controlling weeds in a field containing a crop employing the plants and/or seeds disclosed herein.

Glyphosate-n-acetyltransferase (GLYAT) sequences and methods of use

Compositions and methods comprising polynucleotides and polypeptides having 4-hydroxyphenylpyruvate dioxygenase (HPPD) activity and having insensitivity to an HPPD inhibitor are provided. Further provided are nucleic acid constructs, plants, plant cells, explants, seeds and grain having the HPPD sequences. Various methods of employing the HPPD sequences are provided. Such methods include, for example, methods for producing an HPPD inhibitor tolerant plant, plant cell, explant or seed and methods of controlling weeds in a field containing a crop employing the plants and/or seeds disclosed herein. Methods are also provided to identify additional HPPD variants. Further provided are various methods and compositions that allow the various HPPD polypeptides and variant and fragments thereof to be expressed in a chloroplast or transported to a chloroplast.

Glyphosate-N-acetyltransferase (GLYAT) sequences and methods of use

Compositions and methods comprising polynucleotides and polypeptides having ALS activity and tolerance to at least one ALS inhibitor are provided. In specific embodiments, the sequence has an increased preference for 2-ketobutyrate, when compared to an appropriate control, such as for example, HRA, and/or a preference for 2-ketobutyrate similar to a native ALS. Further provided are nucleic acid constructs, plants, plant cells, explants, seeds and grain having the ALS inhibitor tolerant sequences. Various methods of employing the ALS inhibitor tolerant sequences are provided. Such methods include methods for producing an ALS inhibitor tolerant plant, plant cell, explant or seed and methods of controlling weeds in a field containing a crop employing the plants and/or seeds disclosed herein.

Methods and compositions involving ALS variants with native substrate preference

The present invention generally relates to methods of rapidly and efficiently searching biologically-related data space. More specifically, the invention includes methods of identifying bio-molecules with desired properties, or which are most suitable for acquiring such properties, from complex bio-molecule libraries or sets of such libraries. The invention also provides methods of modeling sequence-activity relationships. As many of the methods are computer-implemented, the invention additionally provides digital systems and software for performing these methods.

Methods, systems, and software for identifying functional bio-molecules

Chimeric polynucleotides comprising a nucleotide sequence encoding a chloroplast transit peptide operably linked to a heterologous polynucleotide of interest are provided, wherein the chloroplast transit peptide comprises an amino acid sequence having the chloroplast transit peptide sequence as set forth in SEQ ID NO:1 or a biologically active variant or fragment thereof or wherein the chloroplast transit peptide comprises the sequence set forth in SEQ ID NO: 58 or an active variant or fragment thereof. Chimeric polypeptides encoding the same, as well as, cells, plant cells, plants and seeds are further provided which comprise the chimeric polynucleotides.
