Within-species variation in traits such as petal size or color often provides reliable information to pollinators about the rewards offered to them by flowers. In spite of potential disadvantages of allowing pollinators to discriminate against less-rewarding flowers, examples of informative floral signals are diverse in form and widely distributed across plant taxa, apparently having evolved repeatedly in different lineages. Although hypotheses about the adaptive value of providing reward information have been proposed and tested in a few cases, a unified effort to understand the evolutionary mechanisms favoring informative floral signals has yet to emerge. This review describes the diversity of ways in which floral signals can be linked with floral rewards within plant species and discusses the constraints and selective pressures on floral signal-reward relationships. It focuses particularly on how information about floral rewards can influence pollinator behavior and how those behavioral changes may, in turn, affect plant fitness, selecting either for providing or withholding reward information. Most of the hypotheses about the evolution of floral signal-reward relationships are, as yet, untested, and the review identifies promising research directions for addressing these considerable gaps in knowledge. The advantages and disadvantages of sharing floral reward information with pollinators likely play an important role in floral trait evolution, and opportunities abound to further our understanding of this neglected aspect of floral signaling.

“…roots, petals, leaves, respectively. Reproductive secretions, such as angiosperm micropylar exudates (Franssen-Verhijen and Willemse, 1993;Dresselhaus and Márton, 2009), carpellate exudates from stigma and style (Lush et al, 2000;Lippi et al, 2011), and gymnosperm pollination drops play major roles in pollen-ovule interactions. The functional setting of an apoplastic fluid is therefore quite important.…”

“…Pigments, especially anthocyanins, are altered by sunlight (Grotewold 2006). Though color change may happen in any pigment, most color changes seem to be associated with variation in anthocyanins (Weiss 1995;Lippi et al 2011). In Viola cornuta (Violaceae) flowers, changes in color are due to anthocyanins; when flowers are grown in the dark, they do not show color change, as opposed to a white to purple change that occurs under light conditions (Farzad et al 2002).…”

Diversity and distribution of flower coloration is a puzzling topic that has been extensively studied, with multiple hypotheses being proposed to account for the functions of coloration, such as pollinator attraction, protection against herbivory, and prevention of damage by ultraviolet light. Recent methodologies have allowed studies to consider the visual system of animals other than humans, helping to answer questions regarding the distribution of flower coloration. A survey of keywords in Web of Science shows floral color to be mainly studied in relation to macroevolutionary traits and biochemistry of pigments, focusing on pollination and anthocyanins, respectively. The present paper reviews mechanisms that determine the color of flowers. First, it is discussed how pigment, visual systems and signaling environments influence flower color; secondly, patterns of convergent evolution of flower color is debated, including evolutionary history, pollinator preference, flower color change, flowering season, and habitat. Third and last, patterns of flower coloration that have been found around the globe are addressed. In short, the aim is to contribute to ongoing research, by underlining mechanisms that lead to global patterns of coloration and indicating perspectives for future study on the topic.
