摘要:
Regulatory regions suitable for directing expression of a heterologous polynucleotide in fruit tissues, e.g., flesh and peel tissues, of plants are described, as well as nucleic acid constructs that include these regulatory regions. Also disclosed are transgenic plants that contain such constructs and methods of producing such transgenic plants.
摘要:
Materials and methods are provided for identifying regulatory region-regulatory protein associations and modulating expression of a sequence of interest. For example, a plant cell is provided containing a regulatory protein that can modulate expression of one or more genes involved in alkaloid biosynthesis in plants, which, in turn, can modulate the amount and/or rate of biosynthesis of one or more alkaloid compounds.
摘要:
Methods and materials for modulating (e.g., increasing or decreasing) nitrogen levels in plants are disclosed. For example, nucleic acids encoding nitrogen-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Plants and plant products having increased nitrogen levels are also disclosed.
摘要:
Materials and methods for modulating expression of nucleic acid sequences of interest, e.g., nucleic acid sequences involved in alkaloid biosynthesis, are disclosed. For example, plants and plant cells containing a regulatory protein that can modulate expression of a gene(s), such as an alkaloid biosynthesis gene(s), are disclosed.
摘要:
Methods and materials for modulating (e.g., increasing or decreasing) carbon levels in plants are disclosed. For example, nucleic acids encoding carbon-modulating polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased carbon levels.
摘要:
Materials and Methods for identifying lignin regulatory region-regulatory protein associations are disclosed. Materials and methods for modulating lignin accumulation are also disclosed.
摘要:
Methods are described herein for producing male-sterile plants by underexpressing the allene oxide synthase (CYP74A) gene. Fertility is restored in the plants by treatment with jasmonic acid. Hybrid seed production is simplified and improved by this invention. The present invention also includes plants transformed with an allene oxide synthase coding sequence.
摘要:
Plants and plant cells having modulated levels of tocopherols and/or tocotrienols are described herein. Materials and methods for making plants and plant cells with modulated levels of tocopherols and/or tocotrienols are also described.
摘要:
Methods are described herein for producing hybrid seed using male-sterile plants wherein reproductive function is restored by treatment of mutant plants with selected plant hormones. Plants comprising mutations in the allene oxide synthase gene are functionally male-sterile and are useful for the production of hybrid seed, wherein fertility is restored in the plants by treatment with jasmonic acid. Hybrid seed production is simplified and improved by this invention. The present invention also includes plants comprising mutations in genes affecting allene oxide synthase and/or hydroperoxide lyase.
