, a Homolog of , is Associated with Flower Bud Differentiation and Floral Organ Morphogenesis in .

is one of the most popular flower plants worldwide. The recurrent flowering trait greatly enhances the ornamental value of roses, and is the result of the constant formation of new flower buds. Flower bud differentiation has always been a major topic of interest among researchers.

An Homolog, , Regulates the Number of Rose Petals Derived From Stamens and Response to Temperature Fluctuations.

, which is a famous traditional flower in China, is a major ornamental plant worldwide. Long-term cultivation and breeding have resulted in considerable changes in the number of rose petals, while most wild Rosaceae plants have only one whorl consisting of five petals. The petals of double flowers reportedly originate from stamens, but the underlying molecular mechanism has not been fully characterized.

Flavonols and Carotenoids in Yellow Petals of Rose Cultivar ( Rosa 'Sun City'): A Possible Rich Source of Bioactive Compounds.

Rose flowers have received increasing interest as rich sources of bioactive compounds. The composition of flavonols and carotenoids in yellow petals of Rosa 'Sun City' was determined by high-performance liquid chromatography coupled with photodiode array and mass spectrometric detectors (HPLC-PDA-MS). In total, 19 flavonols and 16 carotenoids were identified, some of which were first discovered in rose petals.
