Abstract: The present invention relates to a method of improving soybean transformation efficiency, which comprises: transforming a plant cell using a recombinant vector containing a gene of interest and a gene encoding a sulfonylurea herbicide hydrolase; screening and culturing the transformed plant cell by external application of an ALS inhibitor, using the gene encoding the sulfonylurea herbicide hydrolase as a selective marker; selecting a plant cell that has not been killed and/or not been inhibited.

Abstract: Provided are an isolated polynucleotide and a method for controlling insect invasion. The isolated polynucleotide is a plurality of target sequences for controlling target gene c35112 of a coleopteran pest, Monolepta hieroglyphica, comprising: a) a polynucleotide sequence shown as SEQ ID NO: 1; or (b) a polynucleotide sequence having at least 15 or 17 or 19 or 21 contiguous nucleotides of SEQ ID NO: 1, a double-stranded RNA comprising at least one strand complementary to the polynucleotide sequence being capable of inhibiting the growth of coleopteran pests after being ingested by the coleopteran pests; or (c) any one of polynucleotide sequences shown as SEQ ID NO: 3 to SEQ ID NO: 20; or (d) a polynucleotide sequence that hybridizes under stringent conditions to a polynucleotide sequence as defined in (a), (b) or (c).

Abstract: Provided are a resistant protein for use in herbicide dicamba, encoding gene and application thereof, the gene comprising: (a) a nucleotide sequence of an amino acid sequence as shown in SEQ ID NO: 2; or (b) a nucleotide sequence which is complementary to the nucleotide sequence as defined by (a) under stringent conditions; or (c) a nucleotide sequence as shown in SEQ ID NO: 1.

Abstract: 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.

Abstract: Disclosed are a nucleotide sequence and a method for controlling insect invasions, the isolated polynucleotide sequence comprising: (a) a polynucleotide sequence as shown in SEQ ID NO: 1, 2 or 3; or (b) a polynucleotide sequence hybridizing with the polynucleotide sequence defined in (a) under stringent conditions; or (c) a polynucleotide sequence having an identity of not less than 80% to the polynucleotide sequence defined in (a); or (d) a polynucleotide sequence of at least 19 consecutive nucleotides of the polynucleotide sequence defined in (a), wherein a double-stranded RNA comprising at least one strand complementary to the polynucleotide sequence, when ingested by an insect pest from Hemiptera, inhibits growth of the insect pest; or (e) a complementary sequence of the polynucleotide sequence as defined in (a), (b), (c) or (d). The three target sequences for controlling an insect pest from Hemiptera, Lygus, have the advantages of efficiency, specificity, convenience and low cost.

Abstract: 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.

Abstract: The present invention relates to the use of a herbicide-tolerant protein, wherein the method for controlling weeds comprises applying a herbicide containing an effective dose of Sulfometuron-methyl to a plant growth environment where at least one transgenic plant is present, wherein the transgenic plant comprises a nucleotide sequence encoding a thifensulfuron hydrolase in its genome, and compared to other plants without the nucleotide sequence encoding the hydrolase, the transgenic plant has reduced plant damage and/or an increased plant yield. The present invention discloses for the first time that a thifensulfuron hydrolase can show a high tolerance to a Sulfometuron-methyl herbicide, plants containing a nucleotide sequence encoding the thifensulfuron hydrolase are strongly tolerant to the Sulfometuron-methyl herbicide and can at least tolerate 1-fold field concentration, and thus the hydrolase has broad application prospects in plants.
