Flower development is central to angiosperm reproduction and is regulated by a broad range of endogenous and exogenous stimuli. It has been well documented that ambient temperature plays a key role in controlling flowering time; however, the mechanisms by which temperature regulates floral organ differentiation remain largely unknown. | Low temperature-induced DNA hypermethylation attenuates expression of RhAG an AGAMOUS homolog and increases petal number in rose Rosa hybrida
