Resumen:
Ecological interaction and adaptation both depend on phenotypiccharacteristics. In contrast with the common conception of the?adult? phenotype, plant bodies develop continuously during theirlives. Furthermore, the different units (metamers) that compriseplant bodies are not identical copies, but vary extensively withinindividuals. These characteristics foster recognition of plant phenotypesas dynamic mosaics. We elaborate this conception basedlargely on a wide-ranging review of developmental, ecological andevolutionary studies of plant reproduction, and identify its utility inthe analysis of plant form, function and diversification.An expandedphenotypic conception is warranted because dynamic mosaicfeatures affect plant performance and evolve. Evidence demonstratesthat dynamic mosaic phenotypes enable functionalontogeny, division of labour, resource and mating efficiency. Inaddition, dynamic mosaic features differ between individuals andexperience phenotypic selection. Investigation of the characteristicsand roles of dynamic and mosaic features of plant phenotypesbenefits from considering within-individual variation as a functionvaluedtrait that can be analysed with functional data methods.Phenotypic dynamics and within-individual variation arise despitean individual?s genetic uniformity, and develop largely by heterogeneousgene expression and associated hormonal control. Thesecharacteristics can be heritable, so that dynamic mosaic phenotypescan evolve and diversify by natural selection.
