The invention relates to the production of graft-mediated hybrid monocotyledonous plants. Methods for the production of such plants are disclosed herein.

This invention describes a new method of grain production wherein designated male plant pollen may be selected at anytime before pollination of a designated female plant. In the method, a designated female plant having both female and male components is grown. Furthermore, designated male pollen is selected for use in cross-pollinating the designated female plant. Cross-pollination may occur on one more days, is intentional, and occurs at a time when male components are not shedding pollen. The criteria used for selecting designated male pollen may include, but is not limited to, market information and commodity price information. Moreover, the designated male plant pollen may have a different maturity period compared to the designated female, selection may occur after the female has germinated, and/or result in a higher harvested crop value than other available pollen. Accordingly, the process involves the intentional delivery of designated male plant pollen at will, as available either in a preserved pollen bank or real-time collection from male plants as they become available, in a growth chamber for example. The delivered designated male plant pollen is in such amounts and fortuitously timed that it preferentially cross-pollinates the designated female plant. The invention also permits real-time agronomic decision making to influence grain content and constituents to maximize grain value.

A rice cultivar designated CLM04 is disclosed herein. The present invention provides seeds, plants, and plant parts derived from rice cultivar CLM04. Further, it provides methods for producing a rice plant by crossing CLM04 with itself or another rice variety and methods for combating undesired vegetation by contacting the disclosed rice seeds with an AHAS-inhibiting herbicide. The invention also encompasses any rice seeds, plants, and plant parts produced by the methods disclosed herein, including those in which additional traits have been transferred into CLM04 through the introduction of a transgene or by breeding CLM04 with another rice cultivar.

A rice cultivar designated CLL15 is disclosed herein. The present invention provides seeds, plants, and plant parts derived from rice cultivar CLL15. Further, it provides methods for producing a rice plant by crossing CLL15 with itself or another rice variety and methods for combating undesired vegetation by contacting the disclosed rice seeds with an AHAS-inhibiting herbicide. The invention also encompasses any rice seeds, plants, and plant parts produced by the methods disclosed herein, including those in which additional traits have been transferred into CLL15 through the introduction of a transgene or by breeding CLL15 with another rice cultivar.

A method of producing a Gramineae plant, the method comprising (a) expressing in a Gramineae plant or plant cell expression of a polynucleotide encoding OLLS1 as set forth in SEQ ID NO: 12 or 13 or a homolog thereof capable of increasing stigma length of the Gramineae plant, wherein when the expressing is by crossing the plant with another plant expressing the polypeptide, selecting for stigma length is performed using markers located between ST87 to ST99; and (b) growing or regenerating the plant.

The herbicide-tolerant rice cultivar designated ‘PVL03’ and its hybrids and derivatives are disclosed.

High throughput methods are described for identifying combinations of mutations that can be used to improve a phenotypic feature in an organism. Large populations of organisms (e.g., plants) containing different combinations of mutations can be assessed using the methods.

The disclosure isolates and identifies a peptide PEP1 that regulates plant root development and a gene OsPEP1 encoding the same. Exogenous application of PEP1 could inhibit the plant root development. A recombinant expression vector containing the gene or part of the DNA of the gene is obtained, and a transgenic plant with altered root growth and development is obtained by transforming with the recombinant expression vector. Therefore, the peptide can be used as a plant growth regulator, and the gene encoding the same and precursor protein thereof can be used as a potential molecular breeding target for crop improvement, for example, improving crop yield by regulating the growth and development of crop roots.

A composition including: (i) a ds RNA molecule of at least 18 contiguous nucleotides that are essentially identical or essentially complementary to a plant gene or a transcript of said plant gene; and (ii) a transfer agent that conditions a surface of a plant to permeation by the ds RNA molecule into cells of the plant; wherein permeation of the ds RNA molecule into cells of the plant causes a transient reduction in the expression of the gene and wherein the transient reduction in the expression of the gene causes a change in a yield-associated trait of the plant.

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.
