摘要:
Provided are methods and related devices for predicting the presence or level of one or more characteristics of a plant or plant population based on spectral, multi-spectral, or hyper-spectral data obtained by, e.g., remote sensing. The predictions and estimates furnished by the inventive methods and devices are useful in crop management, crop strategy, and optimization of agricultural production.

This invention relates to an isolated nucleic acid fragment encoding a DAHP synthetase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the DAHP synthetase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the DAHP synthetase in a transformed host cell.

The instant invention discloses utilization of a cDNA clone to construct sense and antisense genes for inhibition of starch branching enzyme enzymatic activity in corn. More specifically, this invention concerns a method of controlling the starch fine structure of starch derived from the grain of corn comprising: (1) preparing a chimeric gene comprising a nucleic acid fragment encoding a starch branching enzyme structural gene or a fragment thereof, operably linked in either sense or antisense orientation on the upstream side to a nucleic acid fragment encoding a promoter that directs gene expression in corn endosperm tissue, and operably linked on the downstream side to a nucleic acid fragment encoding a suitable regulatory sequence for transcriptional termination, and (2) transforming corn with said chimeric gene, wherein expression of said chimeric gene results in alteration of the fine structure of starch derived from the grain of said transformed corn compared to the fine structure of starch derived from corn not possessing said chimeric gene.
摘要:
A novel method for prediction of the degree of heterotic phenotypes in plants is disclosed. Structural variation analyzes of the genome are used to predict the degree of a heterotic phenotype in plants. In some examples, copy number variation is used to predict the degree of heterotic phenotype. In some methods copy number variation is detected using competitive genomic hybridization arrays. Further, methods for optimizing the arrays are disclosed, together with kits for producing such arrays, as well as hybrid plants selected for development based on the predicted results.

This invention relates to an isolated nucleic acid fragment encoding a glycolysis or respiration protein. The invention also relates to the construction of a chimeric gene encoding all or a portion of the glycolysis or respiration protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the glycolysis or respiration protein in a transformed host cell.
摘要:
This invention relates to isolated nucleic acid fragments encoding granule-bound starch synthase. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of the granule-bound starch synthase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the granule-bound starch synthase in a transformed host cell.
