Update on Floral Meristem Termination Time to Stop: Flower Meristem Termination
Flowers are the reproductive structure of angiosperms. They are composed of four distinct types of organs: sepals, petals, stamens, and carpels, which typically develop on four concentric rings, or whorls (Fig. 1A). In Arabidopsis (Arabidopsis thaliana), floral organ identity relies on the combinatorial action of four classes of flower-specific transcription factors, expressed in partially over...
متن کاملThe induction and maintenance of flowering in Impatiens.
The mechanisms that establish the floral meristem are now becoming clearer, but the way in which flowering is maintained is less well understood. Impatiens balsamina provides a unique opportunity to address this question because reversion to vegetative growth can be obtained in a predictable way by transferring plants from inductive to non-inductive conditions. Following increasing amounts of i...
متن کاملChemical Aspects of the Inheritance of Flower Color in Impatiens Balsamina L.
ECENT applications of chromatographic techniques ( BATE-SMITH 1948,1949) R have facilitated identification of anthocyanin pigments and related compounds in micro quantities, thus permitting extension of the combined genetic and biochemical work initiated by SCOTT-MONCRIEFF (1931) and extended by many others. The genetic studies by the late D. W. DAVIS and his associates (1958) on the inheritanc...
متن کاملInfluence of Genes Controlling Flower Color on Relative Quantities of Anthocyanins and Flavonols in Petals of Impatiens Balsamina.
N earlier studies concerned with the genetic regulation of pigmentation in the I garden balsam, Impatiens balsamina, the genes which determine the nature of anthocyanin pigmentation were found in individual cases to regulate also the structure of leucoanthocyanins (ALSTON and HAGEN 1958) and flavonols (CLEVENGER 1958). Thus the dominant gene H , while increasing the quantity of pelargonidin der...
متن کاملAnti-Neurodegenerative Biflavonoid Glycosides from Impatiens balsamina.
Four biflavonoid glycosides, balsamisides A-D (1-4), and nine known compounds (5-13) were obtained from the white petals of Impatiens balsamina. The 2D structures of the purified phytochemicals were established using conventional NMR techniques in addition to the new long-range HSQMBC NMR experiment. Acid hydrolysis followed by experimental and quantum-mechanics-based ECD data analysis permitte...
