Flower Color Evolution
The evolution of floral traits in animal-pollinated plants involves the interaction between flowers as signal senders and pollinators as signal receivers. Flower colors are very diverse, effect pollinator attraction and flower foraging behavior, and are hypothesized to be shaped through pollinator. Flower color is a deceivingly simple trait that has been extremely labile during evolution: Sister species from several genera can show substantially different pigmentation patterns, and repeated shifts in flower color are observed within a single genus.
Abstract Premise of the study: Flower color is one of the best-studied floral traits in terms of its genetic basis and ecological significance, yet few studies have examined the processes that shape its evolution across deep timescales. This Research Topic is composed of 28 studies on the role of flower color in angiosperm evolution. These contributions include species living on nearly all continents plucked from most major branches of the angiosperm tree of life (Figure 1).
Evolution: Flip-Flopping Flower Color Defies Dollo’s Law: Current Biology
Flowers are the most commonly seen colourful elements of the natural world, and in this primer we explain the evolution of their spectacular range of colours. To understand flower colour, we first explain what colour is and how a flower can have different colours in the eyes of different observers. We briefly introduce the molecular and biochemical basis of flower colour, which is primarily.

Abstract We review the study of flower color polymorphisms in the morning glory as a model for the analysis of adaptation.
12 Flower Color Variation: A Model for the Experimental Study of ...
The pathway involved in the determination of flower color phenotype is traced from the molecular and genetic levels to the phenotypic level. The downregulation of a second pathway gene was also necessary for the novel flower color, and this regulatory pattern parallels the genetic change in the two other red. Here we explore these questions in relation to flower colour.
Flower colour sits at the intersection of ecological interactions, genetics, and evolution and thus provides an excellent system to understand the causes of variation and, more importantly, what maintains or erodes it.
