A herbicide tolerant protein SUM1, a coding gene thereof and a use thereof, wherein the herbicide tolerant protein comprises: (a) a protein having an amino acid sequence as shown in SEQ ID NO: 1; or (b) a protein which is derived from (a) by substituting and/or deleting and/or adding one or more amino acids in the amino acid sequence of (a), and has the activity of thifensulfuron hydrolase. The herbicide tolerant protein SUM1 can show a higher tolerance to a plurality of sulfonylurea herbicides, can tolerate four-fold field concentration, and thus has a broad application prospect in plants.

Sulfonylurea herbicide resistant transgenic plants

Involved is a herbicide-resistant protein, coding gene and use thereof. The herbicide-resistant protein comprises: (a) a protein consisting of an amino acid sequence shown in SEQ ID NO: 2; or (b) a protein with the activity of herbicide-resistance which is derived from the amino acid sequence in (a) by replacing and/or deleting and/or adding one or several amino acids in the same. The herbicide-resistant protein of this invention is especially suitable for expression in plants, with broad resistance spectrum to herbicides, especially to phenoxy auxin herbicides.

Herbicide-resistant protein, encoding gene and use thereof

Some embodiments of the present invention can include herbicide-resistant proteins, coding genes, and uses thereof. Certain herbicide-resistant proteins can comprises: (a) a protein consisting of an amino acid sequence shown in SEQ ID NO: 2; or (b) a protein consisting of an amino acid sequence at least 90% identical to that set forth in SEQ ID NO: 2. Other herbicide-resistant proteins of this disclosure can be suitable for expression in plants, can have resistance to herbicides (e.g., to phenoxy auxinherbicides), or both.

Herbicide-resistant proteins, encoding genes, and uses thereof

The invention provides isolated ethylene over-producer 1 (ETO1) nucleic acid molecules which are associated with ethylene production in plants and their encoded proteins.

The present disclosure concerns methods and compositions relating to UXS polypeptides and/or nucleic acids encoding UXS polypeptides. In certain claims, the methods and compositions are of use to improve digestibility and/or ease of grain processing. Such improvements relate to a modulation in arabinoxylan and/or hemicellulose content in transgenic plants. Such plants can, for example, comprise one or more nucleic acid sequences that inhibit expression of one or more UDP-Xylose Synthase (USX) genes.

UDP-xylose synthases (UXS) polynucleotides, polypeptides and uses thereof

According to the invention, there is provided a high throughput method for measuring total fermentables using a small amount of plant tissue. A high throughput screening tool for gene discovery aiming for increasing total fermentables is further provided.

High throughput method for measuring total fermentables in small amount of plant part

The present disclosure concerns methods and compositions relating to UXS polypeptides and/or nucleic acids encoding UXS polypeptides. In certain claims, the methods and compositions are of use to improve digestibility and/or ease of grain processing. Such improvements relate to a modulation in arabinoxylan and/or hemicellulose content in transgenic plants. Such plants can, for example, comprise one or more nucleic acid sequences that inhibit expression of one or more UDP-Xylose Synthase (UXS) genes.

The present invention provides compositions and methods for manipulation of plant arabinoxylose and plant xylan synthases. Compositions include novel nucleotide sequences encoding xylan synthases and biologically active variants thereof.
