The Role of Elastic Stresses on Leaf Venation Morphogenesis
We explore the possible role of elastic mismatch between epidermis and mesophyll as a driving force for the development of leaf venation. The current prevalent 'canalization' hypothesis for the formation of veins claims that the transport of the hormone auxin out of the leaves triggers cell differentiation to form veins. Although there is evidence that auxin plays a fundamental role in vein for...
متن کاملLeaf maximum photosynthetic rate and venation are linked by hydraulics.
Leaf veins are almost ubiquitous across the range of terrestrial plant diversity, yet their influence on leaf photosynthetic performance remains uncertain. We show here that specific physical attributes of the vascular plumbing network are key limiters of the hydraulic and photosynthetic proficiency of any leaf. Following the logic that leaf veins evolved to bypass inefficient water transport t...
متن کاملInferring climate from angiosperm leaf venation networks.
Leaf venation networks provide an integrative linkage between plant form, function and climate niche, because leaf water transport underlies variation in plant performance. Here, we develop theory based on leaf physiology that uses community-mean vein density to predict growing season temperature and atmospheric CO2 concentration. The key assumption is that leaf water supply is matched to water...
متن کاملComputer-Supported Deliberations for Distributed Teams
In our terminology, a “deliberation” is a distributed collaborative process, more or less spontaneous, structured, and complex. This process can include both individual and collective activities, synchronous and asynchronous phases. But in every case, its core part is the negotiation of some result through argumentation. This paper describes a comprehensive flexible generic support for distribu...
متن کاملInteractive venation-based leaf shape modeling
We describe a representation for tree leaves and an interactive modeling system for creating realistic close up images of leaf clusters. The planar outline of the leaf and the larger members of its venation system are strong factors in the recognition of plant species and as such are essential to realistic imaging. The larger veins also play a major biological role in determining the leaf surfa...
