摘要:
The present invention relates to nucleic acid sequences for regulating gene expression in plants. In particular, the invention relates to 5′ regulatory sequences which are useful for regulating expression of heterologous DNAs in plants and methods for identifying multiple 5′ regulatory sequences which confer a particular expression profile when operably linked to DNA sequences. The invention also relates to expression vectors containing the 5′ regulatory sequences and to transgenic plants containing the expression vectors.

摘要:
Promoters from male reproductive tissues are isolated from corn and wheat. These promoters can be used in plants to regulate transcription of target genes including genes for control of fertility, insect or pathogen tolerance, herbicide tolerance or any gene of interest.
摘要:
Expressed Sequence Tags (ESTs) isolated from maize are disclosed. The ESTs provide a unique molecular tool for the targeting and isolation of novel genes for plant protection and improvement. The disclosed ESTs have utility in the development of new strategies for understanding critical plant developmental and metabolic pathways. The disclosed ESTs have particular utility in isolating genes and promoters, identifying and mapping the genes involved in developmental and metabolic pathways, and determining gene function. Sequence homology analyses using the ESTs provided in the present invention, will result in more efficient gene screening for desirable agronomic traits. An expanding database of these select pieces of the plant genomics puzzle will quickly expand the knowledge necessary for subsequent functional validation, a key limitation in current plant biotechnology efforts.
摘要:
Utilizing phenotypic markers in seeds or plants to allow qualitative detection of a proprietary trait in the harvest, to allow a quantitative calculation of the amount of the trait, and to facilitate the calculation and collection of fees for the trait. The phenotypic markers of the seeds can be the seed coat color, and said seeds can be homozygous or heterozygous for the phenotypic difference of seed coat color. Commercial cultivars of seeds with the phenotypic difference of seed color may be grown to include several different seed colors. Trait fees may be assessed on all grain with the proprietary trait, whether the grain was produced from purchased seed or from seed saved from a previous harvest.
摘要:
Promoters and genes isolated from genomic DNA of strawberry plants are disclosed. Both the promoters and genes are capable of tissue-specific expression in transgenic plants. A plant promoter that is a nucleic acid region located upstream of the 5' end of a plant DNA structural coding sequence that is transcribed at high levels in ripening fruit tissue. This promoter region is capable of conferring high levels of transcription in ripening fruit tissue and in developing seed tissues when used as a promoter for a heterologous coding sequence in a chimeric gene. The promoter and any chimeric gene in which it may be used can be used to obtain transformed plants or plant cells. A DNA coding sequence that codes for a gene that is highly transcribed in ripening fruit tissue of Fragaria X ananassa. This coding sequence can be used to obtain a cDNA probe useful in obtaining analogous promoters from a homologous coding sequence in other plant species. Chimeric genes including the isolated promoter region, transformed plants containing the isolated promoter region, transformed plant cells and seeds are also disclosed.
