A constant production hypothesis guides leaf venation patterning.
We propose a theoretical mechanism that enables the elaboration of veins to supply distant cells during leaf development. In contrast to the more standard view that a signal (e.g., auxin) is produced at isolated sites to stimulate growth, we determine the consequences of the hypothesis that auxin is produced at a constant rate in every cell. High concentration sites for auxin emerge naturally i...
متن کاملA modern ampelography: a genetic basis for leaf shape and venation patterning in grape.
Terroir, the unique interaction between genotype, environment, and culture, is highly refined in domesticated grape (Vitis vinifera). Toward cultivating terroir, the science of ampelography tried to distinguish thousands of grape cultivars without the aid of genetics. This led to sophisticated phenotypic analyses of natural variation in grape leaves, which within a palmate-lobed framework exhib...
متن کاملThe RON1/FRY1/SAL1 gene is required for leaf morphogenesis and venation patterning in Arabidopsis.
To identify genes involved in vascular patterning in Arabidopsis (Arabidopsis thaliana), we screened for abnormal venation patterns in a large collection of leaf shape mutants isolated in our laboratory. The rotunda1-1 (ron1-1) mutant, initially isolated because of its rounded leaves, exhibited an open venation pattern, which resulted from an increased number of free-ending veins. We positional...
متن کاملThe HVE/CAND1 gene is required for the early patterning of leaf venation in Arabidopsis.
The hemivenata-1 (hve-1) recessive allele was isolated in a search for natural variations in the leaf venation pattern of Arabidopsis thaliana, where it was seen to cause extremely simple venation in vegetative leaves and cotyledons, increased shoot branching, and reduced root waving and fertility, traits that are reminiscent of some mutants deficient in auxin signaling. Reduced sensitivity to ...
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...
