A classical role of the hormone auxin is in the formation of flowers at the periphery of the reproductive shoot apex. Mutants in regulators of polar auxin transport or in the auxin-responsive transcription factor MONOPTEROS (MP) form naked inflorescence "pins" lacking flowers. How auxin maxima and MP direct initiation of flower primordia is poorly understood. Here, we identify three genes whose...
AIM To determine the effect of a Calendula officinalis flower extract on lung metastasis by B16F-10 melanoma cells in C57BL/6 mice. MATERIALS AND METHODS Male mice were injected with B16F-10 melanoma cells through the tail vein and simultaneously treated with C.officinalis flower extract. Parameters studied were lung tumor nodule count, life span of animals, gamma glutamyl transpeptidase acti...
Tchihatchewia isatidea Boiss (Brassicaceae) is popularly known as “Paint and Bridal Flower”. Flower pieces extracts can be used for painting, wound healing, cough treatments. In this study, the nutritional medicinal properties of T. isidea were determined. For purpose, carbohydrate, crude oil, protein, cellulose, energy, ash, dry matter, moisture, element, vitamin, antioxidant capacity, DNA pro...
Flower structure in grasses is very unique. There are no petals or sepals like in eudicots but instead flowers develop bract-like structures - palea and lemma. Reproductive organs are enclosed by round lodicule that not only protects reproductive organs but also plays an important role during flower opening. The first genetic model for floral organ development was proposed 25 years ago and it w...
Sector boundary analysis has been used to deduce the number and orientation of cells initiating flower and floral organ development in Arabidopsis thaliana. Sectors were produced in transgenic plants carrying the Ac transposon from maize inserted between the constitutive 35S promoter and the GUS reporter gene. Excision of the transposon results in a blue-staining sector. Plants were chosen in w...
Phyllody is a flower abnormality in which leaf-like structures replace flower organs in all whorls. Here, we investigated the origin and the molecular mechanism of phyllody phenotype in Rosa chinensis cv. Viridiflora, an ancient naturally occurring Chinese mutant cultivar. Reciprocal grafting experiments and microscopy analyses, demonstrated that the phyllody phenotype in Viridiflora is not ass...
