“…Allsopp, 1965). However, the link between differences in nutrient supply and variation in plant morphology and physiology is a rather general one (Lambers et al, 2008), and no longer discussed as the proximal cause of the ontogenetic changes dealt with in this review.…”

“…The older literature, mostly dealing with morphological and anatomical, but also physiological aspects of heteroblasty, was reviewed in detailed and extensive earlier reviews, e.g. by Troll, 1939, Schaffalitzky de Muckadell, 1959, or Allsopp, 1965, while more recent reviews clearly reflect the advance of molecular techniques . There are also a considerable number of studies trying to demonstrate an extant adaptive function of these ontogenetic changes, although to date most results are negative or inconclusive (Winn, 1999;.…”

Heteroblasty—A Review

2011

Virtually all plants show a certain degree of variation among individual metamers during ontogeny. In some cases, however, there are abrupt and substantial changes in form and function (e.g. in leaf form, leaf size, phyllotaxy, internode length, anthocyanin pigmentation, rooting ability, or wood structure). These plants were called "heteroblastic" by Karl Goebel more than a century ago, but the functional significance of this type of ontogenetic change, the evolutionary trajectories in different plant groups, even their frequency in the plant kingdom are still unresolved issues. We argue that slow progress is partly due to an on-going terminological confusion and the lack of distinction between other developmental processes such as ontogenetic drift. This review develops a conceptual framework for future scientific work, proposes a quantitative index of heteroblasty, and discusses the evidence for developmental regulation, functional significance, and evolutionary implications of heteroblasty to provide a stimulating basis for further research with this fascinating group of plants.Zusammenfassung Fast alle Pflanzen zeigen während der Individualentwicklung ein gewisses Maß an Variabilität einzelner Metamere. Bei manchen Arten kommt es jedoch zu einer ausgeprägten und sprunghaften Änderung in Form und Funktion (z.B. in Blattform oder -stellung, Internodienlänge, Pigmentierung, Holzstruktur, oder hinsichtlich der Fähigkeit zur Bildung von Adventivwurzeln). Obwohl diese Arten von Karl Goebel schon vor mehr als einem Jahrhundert als "heteroblastisch" beschrieben wurden, sind die funktionelle Bedeutung des Phänomens, dessen Evolution innerhalb einzelner Pflanzengruppen, wie auch die Häufigkeit im Pflanzenreich immer noch weitgehend ungeklärt. Dieser schleppende Fortschritt mag mit einem weit verbreiteten terminologischen Durcheinander und dem Fehlen einer klaren Abgrenzung von anderen Entwicklungsprozessen wie der "ontogenetischen Drift" zusammenhängen. Unser Übersichtsartikel entwickelt einen klaren konzeptionellen Rahmen, um eine Basis zu schaffen für zukünftige Forschungsarbeiten dieses faszinierenden Entwicklungsphänomens. Dazu schlagen wir einen quantitativen Index der Heteroblastie vor, skizzieren den gegenwärtigen Wissens- Bot. Rev. (2011) 77:109-151

“…La forme du limbe est également sous la dépendance de la lumière (Njoku, 1956, sur lpomea caerulea ;Allsopp, 1967). L'existence d'effets différentiels selon le caractère dimensionnel ( § 2b et tableau 1) est à relier aux différences de réponses selon le type cellulaire ou tissulaire (V erbelen et De Greef, 1979, sur Phaseolus vulgaris ;Dengler, 1980, :;ur llelianthus annuus).…”

“…Metamorphosis in plants includes the phenomenon of heteroblasty, i.e., genetically programmed changes among successive metamers that occur as a normal expression of whole-plant ontogeny (Ashby, 1948;Jones, 1999). Heteroblastic changes can include such traits as shoot orientation, phyllotaxy, leaf size, shape, anatomy and biochemistry, internode length and width, the fates of lateral meristems, and the capacity to flower (Goebel, 1900;Arber, 1919;Allsopp 1965Allsopp , 1967. The term heteroblasty has also been extended to include more subtle shifts in qualitative and quantitative features of vegetative shoots (Poethig, 1988;1990;Kerstetter and Poethig, 1998;reviewed in Diggle, 1999) and even to morphological changes in floral form within inflorescence axes (Lord, 1979).…”

A developmental morphologist's perspective on plasticity

Abstract. This series of essays addresses plasticity from the perspective of developmental morphology. The first essay deals with the problem of distinguishing between plasticity and other types of ontogenetic variation. In a temporally varying environment, morphological plasticity may be expressed as the production of a succession of different metamers. However, even in a constant environment, plant metamers can vary dramatically, a phenomenon known as heteroblasty. Because heteroblasty and plasticity can yield similar patterns of ontogenetic variation, the two are often confounded in analyses of developmental plasticity. The second essay discusses the integration of plant phenotypic responses and finds that the evidence for integration is equivocal. The third section shows that developmental properties can constrain the expression of morphological plasticity. Developmental lags and the 'epiphenotype problem' are particularly important features for analyses of the evolution and expression of plasticity. Finally, in answer to the question of strategies for studying plasticity, I emphasize the need for research at multiple levels and for the inclusion of a historical or phylogenetic perspective.
