Evolutionary Tradeoffs
In biological systems, traits are often linked in ways that prevent simultaneous optimization of all of them. The resulting ‘evolutionary tradeoffs’ reflect necessary compromises among the functions of multiple traits. Such compromises are particularly clear when energy must be allocated among competing metabolic functions. Energy allocated to growth is not available for reproduction, immune fu...
متن کاملPlant Development: Spacing out Stomatal Pores
How do plants generate the optimal spacing of stomatal pores on their surfaces to prevent excessive water-loss, whilst allowing efficient gas exchange? New research into the ERECTA family of receptor-like-kinases has provided an important link in the cell-cell signalling pathways controlling this process.
متن کاملDiametrical diseases reflect evolutionary-genetic tradeoffs
Tradeoffs centrally mediate the expression of human adaptations. We propose that tradeoffs also influence the prevalence and forms of human maladaptation manifest in disease. By this logic, increased risk for one set of diseases commonly engenders decreased risk for another, diametric, set of diseases. We describe evidence for such diametric sets of diseases from epidemiological, genetic and mo...
متن کاملStomatal Spacing Safeguards Stomatal Dynamics by Facilitating Guard Cell Ion Transport Independent of the Epidermal Solute Reservoir12[CC-BY]
Stomata enable gaseous exchange between the interior of the leaf and the atmosphere through the stomatal pore. Control of the pore aperture depends on osmotic solute accumulation by, and its loss from the guard cells surrounding the pore. Stomata in most plants are separated by at least one epidermal cell, and this spacing is thought to enhance stomatal function, although there are several gene...
