Acetyl-CoA carboxylase herbicide resistant sorghum
View Patent ↗The present invention provides for compositions and methods for producing crop plants that are resistant to herbicides. In particular, the present invention provides for sorghum plants, plant tissues and plant seeds that contain altered acetyl-CoA carboxylase (ACC) genes and proteins that are resistant to inhibition by herbicides that normally inhibit the activity of the ACC protein.
1. A seed producing the germplasm of sorghum hybrid variety KSU 06 GHATx623x714, wherein representative seeds have been deposited under ATCC No. PYA-8034, and wherein:
(i) said germplasm comprises a sorghum acetyl-CoA carboxylase gene comprising a 1664-base portion having a nucleotide sequence represented by SEQ ID NO: 12,
(ii) said sorghum acetyl-CoA carboxylase gene encodes a sorghum acetyl-CoA protein having a tryptophan to cysteine amino acid substitution at an amino acid position aligning with Trp 2027 of SEQ ID NO: 13, and
(iii) the expression of said sorghum acetyl-CoA carboxylase gene confers to said sorghum hybrid grown from said seed resistance to inhibition by one or more aryloxyphenoxypropionate acetyl-CoA carboxylase herbicides at levels of said one or more aryloxyphenoxypropionate herbicides that would normally inhibit the growth of a sorghum hybrid.
2. A method of controlling weeds in the vicinity of a cultivated sorghum hybrid, said method comprising:
a) providing one or more acetyl-CoA carboxylase herbicides,
b) applying said one or more acetyl-CoA carboxylase herbicides to a field comprising a sorghum hybrid plant grown from the seed of claim 1 , and
c) controlling weeds in the vicinity of said cultivated sorghum hybrid such that weed growth is adversely affected by the application of said one or more herbicides and growth of said cultivated sorghum hybrid is not adversely affected.
3. A method of producing an herbicide resistant sorghum plant, said method comprising crossing a sorghum hybrid plant grown from the seed of claim 1 with a different sorghum plant and selecting a progeny plant comprising SEQ ID NO: 12.
