Toward elucidating the mechanisms that regulate heterophylly

open access: yesPlant Morphology, 2012
Introduction The leaves of plants show tremendous variation in size and shape, despite all leaf primordia initially developing as simple protrusions from the flanks of the shoot apical meristem (Tsukaya 2006). Aside from variation among species, some species show abrupt changes in leaf form in response to surrounding environmental conditions.

HpQTL: a geometric morphometric platform to compute the genetic architecture of heterophylly

open access: yesBriefings in Bioinformatics, 2017
Heterophylly, i.e. morphological changes in leaves along the axis of an individual plant, is regarded as a strategy used by plants to cope with environmental change. However, little is known of the extent to which heterophylly is controlled by genes and how each underlying gene exerts its effect on heterophyllous variation.

Heterophylly results in a variety of “spectral signatures” in aquatic plant species

open access: yesAquatic Botany, 2012
Abstract The leaf reflectance spectra (280–887 nm) of two heterophyllous aquatic plant species Polygonum amphibium (L.) and Nuphar luteum (L.) were compared and their relation to physical properties of the leaves examined. In P. amphibium contrasting environmental conditions along water–land gradient affected the majority of anatomical and ...

HETEROPHYLLY IN HIPPURIS, A PROBLEM IN IDENTIFICATION

Canadian Journal of Botany, 1961
Although the primordia of all types of leaves in Hippuris show no distinguishing characteristics until they are 50 microns long, their further development is strongly influenced by their environment. At maturity they can, for convenience, be thought of as belonging to one of five types, or some intermediate of these types. The five types of leaves are:
