Chromatographic fingerprint analysis of the floral parts of Trollius chinensis.
This study provided a practical procedure, for the first time, to compare the component difference of the floral parts of Trollius chinensis and identify the characteristic peaks of each floral part using the high-performance liquid chromatographic fingerprint technique followed by similarity analysis. The results showed that the constituents of different floral parts exhibited lower similarity...
متن کاملFunctional reversion to identify controlling genes in multigenic responses: analysis of floral abortion.
In many situations, organisms respond to stimuli by altering the activity of large numbers of genes. Among these, certain ones are likely to control the phenotype while others play a secondary role or are passively altered without directly affecting the phenotype. Identifying the controlling genes has proven difficult. However, in a few instances, it has been possible to reverse the phenotype b...
متن کاملFloral Reversion in Arabidopsis suecica Is Correlated with the Onset of Flowering and Meristem Transitioning
Angiosperm flowers are usually determinate structures that may produce seeds. In some species, flowers can revert from committed flower development back to an earlier developmental phase in a process called floral reversion. The allopolyploid Arabidopsis suecica displays photoperiod-dependent floral reversion in a subset of its flowers, yet little is known about the environmental conditions enh...
متن کاملDown-regulation of TM29, a tomato SEPALLATA homolog, causes parthenocarpic fruit development and floral reversion.
We have characterized the tomato (Lycopersicon esculentum Mill.) MADS box gene TM29 that shared a high amino acid sequence homology to the Arabidopsis SEP1, 2, and 3 (SEPALLATA1, 2, and 3) genes. TM29 showed similar expression profiles to SEP1, with accumulation of mRNA in the primordia of all four whorls of floral organs. In addition, TM29 mRNA was detected in inflorescence and vegetative meri...
متن کاملExtraction and application of natural dye preparations from the floral parts of Woodfordia fruticosa (Linn.) Kurz
India has a rich biodiversity and harbours a wealth of useful germplasm resources and there is no doubt that the plant kingdom is a treasure-house of diverse natural products. One such product from nature is the dye. Dyes are one of the most important uses of the plants. Recently, interest in the use of natural dyes has been growing rapidly due to the result of stringent environmental standards...
