Abstract: The present invention provides chemically regulatable DNA sequences capable of regulating transcription of an associated DNA sequence in plants or plant tissues, chimeric constructions containing such sequences, vectors containing such sequences and chimeric constructions, and transgenic plants and plant tissues containing these chimeric constructions. In one aspect, the chemically regulatable DNA sequences of the invention are derived from the 5′ region of genes encoding pathogenisis-related (PR) proteins. The present invention also provides anti-pathogenic sequences derived from novel cDNAs coding for PR proteins which can be genetically engineered and transformed into plants to confer enhanced resistance to disease.

Abstract: The present invention is directed to the production of male sterile plants by providing them with a recombinant DNA capable of specific expression in the male reproductive system of a plant of the enzyme trehalose phosphate (TPP). Resotration of the fertility can be established either by providing said male sterile plants with a recombinant DNA capable of expression of trehalose phosphate synthase (TPS) under control of an inducible promoter or with a recombinant DNA capable of expression of a suppressor protein which suppresses expression of TPP under control of an inducible promoter. This inducible restoration possibilities enable the maintenance of a homozygous male sterile line. Restoration can also be done by spraying the male sterile plants with gibberellic acid.

Abstract: The present invention provides a method for hybrid seed production comprising producing a conditional female sterile plant comprising a female-preferential promoter operably linked to a coding sequence which encodes an enzyme which catalyzes the conversion of a protoxin to a toxin, interplanting the conditional female sterile plant with a male sterile plant, applying the protoxin to the conditional female sterile plant, and producing hybrid seed. Viable seed formation is prevented on the conditional female sterile plant as a result of the conversion of the protoxin to the toxin in the female reproductive structures, and pollen production is prevented on the male sterile plant, thus allowing interplanting of the two parents of the hybrid cross in order to provide more efficient pollen transfer. Also provided are expression cassettes useful in the invention, plants transformed with the expression cassette, and novel female-preferential promoters.

Abstract: The invention relates to genes isolated from Arabidopsis that code for proteins essential for seedling growth. The invention also includes the methods of using these proteins to discover new herbicides, based on the essentiality of the genes for normal growth and development. The invention can also be used in a screening assay to identify inhibitors that are potential herbicides. The invention is also applied to the development of herbicide tolerant plants, plant tissues, plant seeds, and plant cells.

Abstract: The present invention relates to methods for controlling the growth of undesired vegetation comprising applying an effective amount of a protox-inhibiting herbicide to a population of transgenic plants or plant seed transformed with a DNA sequence coding for a modified protox enzyme that is tolerant to a protox-inhibiting herbicide or to the locus where a population of the transgenic plants or plant seeds is cultivated.

Abstract: The present invention provides novel eukaryotic DNA sequences coding for native protoporphyrinogen oxidase (protox) or modified forms of the enzyme which are herbicide tolerant. Plants having altered protox activity which confers tolerance to herbicides are also provided.
