摘要:
Presently provided are a cineraria-derived polynucleotide which can act as a promoter for a coding region of flavonoid 3′,5′-hydroxylase (F3′5′H and a F3′5′H gene construct which carries the polynucleotide. The cineraria-derived petal-specific promoter can be as polynucleotide having the nucleotide sequence depicted in SEQ ID NO: 9 or a polynucleotide which can hybridize with the polynucleotide having the nucleotide sequence depicted in SEQ ID NO: 9 under stringent conditions and can act as a promoter for a coding region of flavonoid. 3′,5′-hydroxylase (F3′5′H). The gene construct can be used, for inhibiting the expression of a gene in an RNAi method, which has, as a loop, a polynucleotide comprising the whole or a part of a first intron of the presently provided cineraria-derived polynucleotide.

摘要:
The present invention relates generally to peptides, polypeptides or proteins having one or more amino acids or one or more amino acid sequences which exhibit color-facilitating properties, either on their own or following interaction with one or more other amino acids and to nucleic acid molecules encoding same. Such peptides, polypeptides and proteins are referred to herein as “color-facilitating molecules” or “CFMs”. The present invention further provides genetic constructs for use in genetically modifying eukaryotic or prokaryotic cells and more particularly eukaryotic tissue so as to alter their visual characteristics or capacity for exhibiting same to a human eye in the absence of excitation by an extraneous non-white light or particle emission. The present invention, therefore, extends to eukaryotic or prokaryotic cells and more particularly eukaryotic tissue, which are genetically modified to produce CFMs and which thereby exhibit altered visual characteristics in the absence of excitation by an extraneous non-white light or particle emission. In one particular embodiment, the CFMs are used to alter the visual characteristics of plants and even more particularly flower color. In another embodiment, the present invention provides gels or coatings or similar biomaterials in the form of a biomatrix comprising the CFMs such as for use as a UV sink, in a sun screen, in cosmetics, as an expression marker or other reporter molecule or for use as a photon trap to increase light intensity.
摘要:
A new cultivar of Dianthus plant named ‘FLORIJADE’ is characterized, inter alia, by pronounced spray habit, perennial and profuse bloom, and green foliage. Dianthus ‘FLORIJADE’ is suitable for use, for example, as a flowering plant in pots, containers, window boxes, and the garden, but is primarily suited for the production of cut flowers. Dianthus ‘FLORIJADE’ is not hardy and is typically grown in a glasshouse. These traits set ‘FLORIJADE’ apart from all existing varieties, lines, strains, or sports of Dianthus. In particular, Dianthus ‘FLORIJADE’ has bright purple/violet flowers.
