The Rosa chinensis cv. Viridiflora Phyllody Phenotype Is Associated with Misexpression of Flower Organ Identity Genes
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...
متن کاملChanges in Cytokinins before and during Early Flower Bud Differentiation in Lychee (Litchi chinensis Sonn.).
Lychee (Litchi chinensis) has been analyzed for cytokinins in buds before and after flower bud differentiation, using reversephase high performance liquid chromatography in combination with Amaranthus bioassay and gas chromatography-mass spectrometry-selected ion monitoring. Four cytokinins, zeatin, zeatin riboside, N(6)-(delta(2)-isopentenyl)adenine, and N(6)-(delta(6)-isopentenyl) adenine rib...
متن کاملmolecular and physiological characterizations of floral scent production in rosa damascena mill.
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
In Vitro Flower Bud Formation, Plant Regeneration and Morphogenetic Studies in Local Scented Cultivar of Rosa indica
In vitro propagation of rose (Rosa indica) as well as rose breeding is a valuable economic enterprise and has received highest importance globally including Indian subcontinent. The development of new cultivars for commerce is faced with new challenges. In vitro micropropagation protocols of varieties of roses have been established but very few reports on the clonal propagation of local cultiva...
متن کاملOrchestration of floral initiation by APETALA1.
The MADS-domain transcription factor APETALA1 (AP1) is a key regulator of Arabidopsis flower development. To understand the molecular mechanisms underlying AP1 function, we identified its target genes during floral initiation using a combination of gene expression profiling and genome-wide binding studies. Many of its targets encode transcriptional regulators, including known floral repressors....
