Abstract
Abstract The present invention provides a maize plant wherein the growth and development of said plant is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, at levels which normally inhibit the growth and development of maize, wherein said tolerance is conferred by an altered acetyl coenzyme A carboxylase (ACCase) tolerant of inhibition by said herbicide at levels which normally inhibit the activity of an unaltered ACCase.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
54 words
A maize plant wherein the growth and development of said plant is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, wherein said tolerance is conferred by an acetyl coenzyme A carboxylase (ACCase) tolerant of inhibition by said herbicide at levels which normally inhibit the activity of an ACCase.
Claim 2
Dependent Claim
54 words
A maize plant wherein the growth and development of said plant is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, wherein said tolerance is conferred by an acetyl coenzyme A carboxylase (ACCase) tolerant of inhibition by said herbicide at levels which normally inhibit the activity of an ACCase.
Claim 3
Dependent Claim
11 words
The maize plant of claim 1, wherein the herbicide is sethoxydim.
Claim 4
Dependent Claim
11 words
The maize plant of claim 1, wherein the herbicide is haloxyfop.
Claim 5
Dependent Claim
16 words
The maize plant of claim 1 wherein said herbicide is a mixture of sethoxydim and haloxyfop.
Claim 6
Dependent Claim
19 words
The maize plant of claim 2 having the characteristics of a maize plant derived from seed S-2 (ATCC 40507).
Claim 7
Dependent Claim
19 words
The maize plant of claim 3 having the characteristics of a maize plant derived from seed H-1 (ATCC 40508).
Claim 8
Dependent Claim
62 words
A maize seed from which a maize plant can be grown wherein the growth and development of said maize plant is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, wherein said tolerance is conferred by an acetyl coenzyme A carboxylase (ACCase) tolerant of inhibition by said herbicide at levels which normally inhibit the activity of ACCase.
Claim 9
Dependent Claim
62 words
A maize seed from which a maize plant can be grown wherein the growth and development of said maize plant is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, wherein said tolerance is conferred by an acetyl coenzyme A carboxylase (ACCase) tolerant of inhibition by said herbicide at levels which normally inhibit the activity of ACCase.
Claim 10
Dependent Claim
11 words

Claim 11
Dependent Claim
11 words
The maize seed of claim 7 wherein the herbicide is haloxyfop.
Claim 12
Dependent Claim
16 words
The maize seed of claim 7 wherein said herbicide is a mixture of sethoxydim and haloxyfop.
Claim 13
Dependent Claim
14 words
The maize seed of claim 8 having the characteristics of seed S-2 (ATCC 40507).
Claim 14
Dependent Claim
14 words
