Viewing leaf structure and evolution from a hydraulic perspective
More than 40 000 km year of water flows through the intricate hydraulic pathways inside leaves. This water not only sustains terrestrial productivity, but also constitutes nearly70%of terrestrial evapotranspiration, thereby influencing both global and local climate (Chapin et al. 2002). Thus, the central role played by leaf vascular systems in terrestrial biology provides an important context f...
متن کاملLeaf Hydraulic Architecture and Stomatal Conductance: A Functional Perspective.
The structure of leaf vasculature viewed over a broad phylogenetic scale from lycophytes to eudicots correlates with stomatal conductance, providing the basis for the hypothesis that increasing vein density drove the evolution of high fluxes in angiosperms. Yet, the relationship between vascular geometry and gas fluxes breaks down at finer phylogenetic scales. In this Update, we derive a simple...
متن کاملEnvironmental hydraulic engineering: a perspective
Hydraulic engineering is the science of water in motion, and mainly dealing with the interactions between the flowing fluid and its surrounding environment. The technical challenges are huge [2]. The levels of complexity are closely linked with the variety of water systems, the broad range of relevant time and length scales, the variability of water systems from droughts to gigantic floods, the...
متن کاملGene Family: Structure, Organization and Evolution
Gene families are considered as groups of homologous genes which they share very similar sequences and they may have identical functions. Members of gene families may be found in tandem repeats or interspersed through the genome. These sequences are copies of the ancestral genes which have underwent changes. The multiple copies of each gene in a family were constructed based on gene duplicati...
متن کاملCorrelated evolution of stem and leaf hydraulic traits in Pereskia (Cactaceae).
Recent studies have demonstrated significant correlations between stem and leaf hydraulic properties when comparing across species within ecological communities. This implies that these traits are co-evolving, but there have been few studies addressing plant water relations within an explicitly evolutionary framework. This study tests for correlated evolution among a suite of plant water-use tr...
