摘要:
The present invention relates to a method for enhancing a plant's resistance to fungal diseases by reducing expression of polyphenol oxidase (PPO). The present invention also relates to a method for improving a potato plant's anti-bruising trait. By using antisense technology to generate transgenic potato plants with tuber-specific promoters, PPO can be reduced to a level at which the potato tubers sufficiently increases its resistance to fungal disease symptoms including late blight caused by Phytophthora infestans. Also provided are certain novel combinations of promoters and PPO-derived sequences which also provide improvements in tuber bruise susceptibility.
摘要:
Antifungal polypeptides, isolated from Medicago plants, are shown to control fungal damage to plants. The polypeptides can be formulated into compositions useful in controlling undesired fungi.
摘要:
The invention provides DNA compositions that relate to transgenic insect resistant maize plants. Also provided are assays for detecting the presence of the maize DAS-59122-7 event based on the DNA sequence of the recombinant construct inserted into the maize genome and the DNA sequences flanking the insertion site. Kits and conditions useful in conducting the assays are provided.
摘要:
Antifungal polypeptides, isolated from Medicago plants, are shown to control fungal damage to plants. DNA encoding the polypeptides was cloned into vectors for transformation of plant-colonizing microorganisms or plants, thereby providing a method of inhibiting fungal growth on plants. The polypeptides can be formulated into compositions useful in controlling undesired fungi.
摘要:
Transgenic plants and host cells comprising antifungal polypeptides, isolated from alfalfa plants, are shown to possess antifungal activity. DNA encoding the polypeptides was cloned into vectors for transformation of plant, therby providing a method of inhibiting fungal growth on plants.
