RICE GRAIN WITH REDUCED ROS1A ACTIVITY
The present invention relates to rice grain with thickened aleurone. Also provided is a rice plant comprising at least one genetic variation which reduces the activity of at least one ROS1a gene in the plant. Grain of the invention, or aleurone there-from, has improved nutritional properties, and hence is particularly useful for human and animal feed products.

Alteration of tobacco alkaloid content through modification of specific cytochrome P450 genes
Compositions and methods for reducing the level of nornicotine and N′-nitrosonornicotine (NNN) in Nicotiana plants and plant parts thereof are provided. The compositions comprise isolated polynucleotides and polypeptides for cytochrome P450s that are involved in the metabolic conversion of nicotine to nornicotine in these plants. Expression cassettes, vectors, plants, and plant parts thereof comprising inhibitory sequences that target expression or function of the disclosed cytochrome P450 polypeptides are also provided. Methods for the use of these novel sequences to inhibit expression or function of cytochrome P450 polypeptides involved in this metabolic conversion are also provided. The methods find use in the production of tobacco products that have reduced levels of nornicotine and its carcinogenic metabolite, NNN, and thus reduced carcinogenic potential for individuals consuming these tobacco products or exposed to secondary smoke derived from these products.

Virus-resistant plant and method for producing the same
An object of the present invention is to provide a cucumber mosaic virus (CMV)-resistant solanaceous plant. The present invention provides a CMV-resistant solanaceous plant having a mutated eIF4E gene encoding an eIF4E protein nonfunctional for CMV. In addition, the present invention provides a method for producing a CMV-resistant plant, the method comprising mutating an eIF4E gene of a solanaceous plant into a mutated eIF4E gene encoding an eIF4E protein nonfunctional for CMV.
Methods of controlling weed of the <i>Amaranth </i>genus
Methods of Amaranthus control are provided, comprising, artificially pollinating an Amaranthus species at a growth area with an effective amount of pollen that reduces fitness of the at least one Amaranthus species, the effective amount comprising 1 mg to 1 gram per plant per application using a precision tool-assisted application or 10 gram to 100 kg per acre per application using a non-precision tool-assisted application during a flowering season of the Amaranthus species.

Methods for producing a complex transgenic trait locus
Methods for producing in a plant a complex transgenic trait locus comprising at least two altered target sequences in a genomic region of interest are disclosed. The methods involve the use of two or more double-strand-break-inducing agents, each of which can cause a double-strand break in a target sequence in the genomic region of interest which results in an alteration in the target sequence. Also disclosed are complex transgenic trait loci in plants. A complex transgenic trait locus comprises at least two altered target sequences that are genetically linked to a polynucleotide of interest. Plants, plant cells, plant parts, and seeds comprising one or more complex transgenic trait loci are also disclosed.
