Abstract: The present invention provides a method of producing rice lines that carry genes that have been modified by T-DNA/GUS based insertional mutagenesis. The GUS portion of the insert is promoterless, so that the GUS gene is expressed only when it is inserted into an active gene. In this way, organ preferential expression of various rice genes can be determined. The invention is also directed to the organ-preferential genes found by the T-DNA/GUS insertional mutagenesis method, as well as the proteins encoded by them. The invention also involves a database having information about the rice lines, such as the genes having the insert, the encoded proteins, the phenotypic characteristics of the mutant lines, and promoter activity of the tagged genes.

Abstract: This invention describes novel DNA sequences which function as promoters of anther-specific transcription of coding DNA sequences in recombinant or chimeric DNA sequences. The invention also describes recombinant or chimeric DNA sequences, which are expressed specifically in the anther of a plant. The said recombinant or chimeric DNA sequences may be used to create transgenic plants, but especially transgenic male-sterile plants.

Abstract: Disclosed are methods and compositions for increasing the expression and recovery of heterologous polypeptides secreted by cultured plant cells, including DNA constructs for high-level gene expression, seretion of heterologous polypeptides through both the plasma membrane and cell wall into the plant culture medium to facilitate protein recovery, and novel plant culture media. Recovery of secreted heterologous polypeptides from plant cell culture medium is significantly improved by including in the plant culture medium a polypeptide stabilizer such as polyvinylpyrrolidone.

Abstract: The present invention provides compositions and methods for affecting the transition from vegetative to reproductive growth in a wide variety of plants. A MADS-box gene from rice, OsMADS1, has been isolated and sequenced. Expression of OsMADS1 in transgenic plants dramatically alters development, resulting in early flowering plants with reduced apical dominance, causing both long-day and short-day plants to flower under both short-day and long-day conditions. OsMADS1 is a key regulatory factor determining the transition from shoot apex to floral meristem and is a target for action of flower induction signals.

Abstract: A rice cDNA clone termed OsMADS1 has been isolated. The sequence of this cDNA is presented. Expression of OsMADS1 in transgenic tobacco plants dramatically alters development, resulting in short, bushy, early flowering plants with reduced apical dominance. It is proposed that the OsMADS1 gene is involved in flower induction and may therefore be used to produce plants with altered phenotypic characteristics.

Abstract: A method of controlling growth and development of plants is provided herein. More particularly, a method of controlling growth and development of potato plants by increasing or decreasing the expression of a gene encoding calmodulin is set forth. Transgenic potato plants carrying sense nucleic acid constructs of pPCM-1, a cDNA clone of potato calmodulin, exhibit unexpected increased shoot and tuber growth, whereas plants carrying antisense nucleic acid constructs exhibit decreased shoot and tuber growth.
