Ferns are less dependent on passive dilution by cell expansion to coordinate leaf vein and stomatal spacing than angiosperms

Ferns are less dependent on passive dilution by cell expansion to coordinate leaf vein and stomatal spacing than angiosperms Carins Murphy MR, Jordan GJ, Brodribb TJ (2017) Ferns are less dependent on passive dilution by cell expansion to coordinate leaf vein and stomatal spacing than angiosperms. PLOS ONE 12(9): e0185648. https://doi.org/10.1371/journal.pone.0185648

Producing leaves with closely spaced veins is a key innovation linked to high rates of photo- synthesis in angiosperms. A close geometric link between veins and stomata in angio- sperms ensures that investment in enhanced venous water transport…

The influence of branch order on optimal leaf vein geometries: Murray’s Law and area preserving branching

Price CA, Knox S-JC, Brodribb TJ (2013) The Influence of Branch Order on Optimal Leaf Vein Geometries: Murray’s Law and Area Preserving Branching. PLoS ONE 8(12): e85420. doi:10.1371/journal.pone.0085420

Models that predict the form of hierarchical branching networks typically invoke optimization based on biomechanical similitude, the minimization of impedance to fluid flow, or construction costs. Unfortunately, due to the small size and high number of vein segments…

Understanding the low photosynthetic rates of sun and shade coffee leaves: bridging the gap on the relative roles of hydraulic, diffusive and biochemical constraints to photosynthesis.

Martins, S. C. V, Galmés, J., Cavatte, P. C., Pereira, L. F., Ventrella, M. C., & Damatta, F. M. (2014). Understanding the low photosynthetic rates of sun and shade coffee leaves: bridging the gap on the relative roles of hydraulic, diffusive and biochemical constraints to photosynthesis. PloS One, 9(4), e95571. doi:10.1371/journal.pone.0095571

It has long been held that the low photosynthetic rates (A) of coffee leaves are largely associated with diffusive constraints to photosynthesis. However, the relative limitations of the stomata and mesophyll to the overall diffusional constraints to photosynthesis,…
