Why is leaf shape so variable

  title={Why is leaf shape so variable},
  author={Catherine A Kidner and Saima Umbreen},
The genetic pathways which control leaf shape have been revealed through work in a range of model systems. We are now beginning to understand how plants produce leaves of different shapes. However, why leaves have different shapes is not so well-studied. Leaf shape is extremely variable between species. Shape also varies within species, within populations and as a plastic or developmentally programmed response, within individual plants, suggesting there is an adaptive role for leaf shape… Expand

Leaf shape exhibits tremendous diversity in angiosperms. It has long been argued that leaf shape can affect major physiological and ecological properties of plants and thus is likely to be adaptive,Expand
Leaf shape deters plant processing by an herbivorous weevil
Researchers have discovered the preference of a leaf-processing herbivore for non-lobed leaves, indicating that leaf shape is an adaptive trait. Expand
A common developmental program can produce diverse leaf shapes
A computational model of leaf development is proposed that generalizes the largely conserved molecular program for the reference plants Arabidopsis thaliana, Cardamine hirsuta and Solanum lycopersicum and shows that small variations of this model can produce diverse leaf shapes, from simple to lobed to compound.

Morphological variation of leaf traits in the Ternstroemia lineata species complex (Ericales: Penthaphylacaceae) in response to geographic and climatic variation
In this study, a complex pattern of differentiation with some isolated populations and some other contiguous populations differentiated by different traits is found within the T. lineata species complex. Expand
Traits influence detection of exotic plant species in tropical forests
It is indicated that information on traits might improve predictions about exotic species detection, which can then be used to optimise the allocation of search effort for efficient species management. Expand
The Morphological and Anatomical Traits of the Leaf in Representative Vinca Species Observed on Indoor- and Outdoor-Grown Plants
The cellular to intercellular space ratio of the Vinca leaf’s mesophyll was revealed herein with the help of computational analysis, and Ultrastructural characteristics of the cuticle and its epicuticular waxes were described for the first time. Expand
Nitrate Reductase-Mediated Nitric Oxide Regulates the Leaf Shape in Arabidopsis by Mediating the Homeostasis of Reactive Oxygen Species
As a gaseous biological signaling molecule, nitric oxide (NO) regulates many physiological processes in plants. Over the last decades, this low molecular weight compound has been identified as a keyExpand
Botanical Digitization: Application of MorphoLeaf in 2D Shape Visualization, Digital Morphometrics, and Species Delimitation, using Homologous Landmarks of Cucurbitaceae Leaves as a Model
The results demonstrate that MorphoLeaf can quantitatively track diversity in leaf specimens, and it can be applied to functionally integrate morphometrics and shape visualization in the digital identification of plants. Expand
A non-coding plastid DNA phylogeny of Asian Begonia (Begoniaceae): evidence for morphological homoplasy and sectional polyphyly.
The presented phylogeny provides for the first time a reasonably resolved and supported phylogenetic framework for Asian Begonia which has the power to inform future taxonomic, biogeographic and evolutionary studies. Expand
Studying genetics of leaf shape variation in Arabidopsis lyrata
The relationship between leaf and its environment has resulted in a tremendous diversification of leaf shape within and between plants species, which is important to cope with the differing environExpand

  • The International journal of developmental biology
  • 2005
The mechanisms of leaf shape control in a model plant, Arabidopsis thaliana, is reviewed, focusing on genes that fulfill special roles in leaf development, to suggest the existence of some systems for integration between cell cycling and cell enlargement in leaf primordia via cell-cell communication.

The Functional Significance and Fitness Consequences of Heterophylly

  • 1999
This work suggests that the significance of longitudinal asymmetry created by heterophylly is case specific and may constitute adaptation to fine‐grained environmental variation, and others may simply reflect inevitable effects of environmental factors on leaf development that have ultimately neutral or negative effects on individual fitness. Expand
The genetic basis of plant form
Evidence supporting this hypothesis includes single gene control of coordinated changes among successive internodes, genetic control of production of metabolites or signals that move from mature tissues to shoot growing points, and allometries connecting organs arising from the same meristem.

Leaf shape variation and herbivore consumption and performance: a case study with Ipomoea hederacea and three generalists
The results suggest that the effects of leaf shape variation on insect performance are likely to vary between insect species, growth conditions of the plant, and the developmental stage and age of leaves sampled. Expand
The Impact of Leaf Shape on the Feeding Preference of Insect Herbivores: Experimental and Field Studies with Capsella and Phyllotreta
It is concluded that Brown & Lawton's hypothesis is at best weakly supported by laboratory data for vine weevils, refuted by laboratoryData for Spodoptera, and consistently refuted by both laboratory and field data for flea beetles. Expand
Natural Selection on a Leaf-Shape Polymorphism in the Ivyleaf Morning Glory (Ipomoea Hederacea)

Computer simulations of heterozygote advantage under the high selfing rates of I. hederacea indicate that balancing selection of the magnitude observed can by itself stabilize the polymorphism, although spatially and temporally variable selection may also contribute to its long-term maintenance.

Sizes and Shapes of Liane Leaves
Two evolutionary models to account for ecological patterns in the size and shape of vine leaves are developed, which predict large, cordate-based leaves with long petioles are favored in sunny situations, while small, narrow-based Leaves with short petiole areavored in more shady environments.
