摘要:
The present invention provides a non-naturally occurring seed plant that is characterized by delayed seed dispersal due to ectopic expression of a nucleic acid molecule encoding an AGL8-like gene product. Further provided herein is a non-naturally occurring seed plant, such as an agl1 agl5 double mutant, that is characterized by delayed seed dispersal due to suppression of AGL1 and AGL5 expression in the seed plant. The invention also provides a substantially purified dehiscence zone-selective regulatory element, which includes a nucleotide sequence that confers selective expression upon an operatively linked nucleic acid molecule in the valve margin or dehiscence zone of a seed plant. Also provided by the invention are kits for producing a transgenic seed plant characterized by delayed seed dispersal, such kits containing a dehiscence zone-selective regulatory element.
摘要:
Plants having modulated expression of a HAF or BEE polypeptide and which modulate aspects of plant fertility, such as parthenocarpy, fertilization efficiency, and/or fruit size, are described. Methods of modulating fertility characteristics in a plant by modulating the expression of a HAF or BEE polypeptide in the plant are also described.
摘要:
The present invention provides a transgenic plant characterized by suppressed flowering. The transgenic plant contains a nucleic acid molecule including a floral organ selective regulatory element operatively linked to a nucleotide sequence encoding a cytotoxic gene product, wherein the nucleic acid molecule is heritable by progeny thereof.
摘要:
The present invention provides plants that exhibit modulated reproductive development and methods of modulating the timing of reproductive development in plants.

摘要:
The present invention provides methods of enhancing lignin biosynthesis in plants. The invention provides, for example, a method of enhancing lignification in a vascular plant by ectopically expressing a nucleic acid molecule encoding an AGL1-like gene product, or an AGL1-like gene product and an AGL5-like gene product in the plant.
摘要:
The present invention provides methods of selectively controlling lignin biosynthesis in plants such that lignification is reduced or enhanced, as desired. The invention provides, for example, a method of reducing lignification in a vascular plant by ectopically expressing a nucleic acid molecule encoding an AGL8-like gene product in the plant, whereby lignification is reduced due to ectopic expression of the nucleic acid molecule. An AGL8-like gene product useful in the invention can have, for example, substantially the amino acid sequence of an AGL8 ortholog such as Arabidopsis AGL8 (SEQ ID NO:2).
