A new cultivar of Heuchera of hybrid origin, `Tiramisu`, characterized by its flat, orbicular-shaped leaves with unique coloration that changes throughout the growing season and with the temperature of the growing conditions. In the spring, the leaves are yellow-green to yellow and moderately mottled with red. In the summer, the leaves become greener with a silvery overlay. In the fall with cool temperatures, new leaves emerge that are yellow-green and heavily mottled with red with yellow-green ...

A new cultivar of Heuchera of hybrid origin, `Pinot Noir`, characterized by its relatively small, broadly ovate shaped leaves held on purple petioles that are dark purple-grey in color when they emerge and developing a silver overlay with dark purple veins as they mature. `Pinot Noir` is further characterized by its mounded and compact plant habit, its tolerance to high heat and humidity, its vigorous growth habit, its early blooming habit with abundant, creamy white flowers and its hardiness in...

A new Cuphea plant, particularly distinguished by its deep red flower color and compact plant habit.

A new variety of orchid plant of the Oncidiinae Intergenerics, Beallara, named Beallara Big Shot `Hilo Sparkle`, distinguished particularly by a clean striking color and large star-shaped flowers that are arranged pleasingly on a raceme and growing quickly to sexual maturity.

A new Poinsettia plant particularly distinguished by its compact, V-shape plant habit, strong stems, good branching and pink bracts is disclosed.

Methods and compositions for modulating plant development are provided. Polynucleotide sequences and amino acid sequences encoding isopentenyl transferase (IPT) polypeptides are provided. The sequences can be used in a variety of methods including modulating root development, modulating floral development, modulating leaf and/or shoot development, modulating senescence, modulating seed size and/or weight, and modulating tolerance of plants to abiotic stress. Polynucleotides comprising an IPT pro...

Artificial plant minichromosomes comprising a functional centromere which specifically bind centromeric protein C (CENPC) and methods for making such minichromosomes are described.

The present invention provides methods for high efficiency plant transformation via Agrobacterium-mediated T-DNA conjugation to suspension-cultured cells or calli. The methods described herein employ membranes of filters as porous solid support for the co-culture of T-DNA donor and recipient.

Methods and compositions for modulating plant development are provided. Polynucleotide sequences and amino acid sequences encoding cytokinin oxidase polypeptides are provided. The sequences can be used in a variety of methods including modulating root development, modulating floral development, modulating leaf and/or shoot development, modulating seed size and/or weight, modulating tolerance under abiotic stress, and modulating resistance to pathogens. Polynucleotides comprising CKX promoters ar...

The invention relates to novel RacB cDNA sequences from barley and to expression cassettes and vectors comprising these promoter sequences. The invention furthermore relates to transgenic plants transformed with these expression cassettes or vectors, to cultures, parts or transgenic propagation material derived from them, and to their use for the production of foodstuffs, feeding stuffs, seed, pharmaceuticals or fine chemicals. The invention furthermore relates to methods of generating or increa...
