Are flowers vulnerable to xylem cavitation during drought?

Zhang F-P, Brodribb TJ (2017) Are flowers vulnerable to xylem cavitation during drought? Proc. R. Soc. B 284:20162642. http://dx.doi.org/10.1098/rspb.2016.2642

Water stress is known to cause xylem cavitation in the leaves, roots and stems of plants, but little is known about the vulnerability of flowers to xylem damage during drought. This is an important gap in our understanding…

Angiosperm leaf vein evolution was physiologically and environmentally transformative.

Boyce CK, Brodribb TJ, Feild TS, Zwieniecki MA. 2009. Angiosperm leaf vein evolution was physiologically and environmentally transformative. Proceedings of the Royal Society of London Series B 276: 1771-1776.

The veins that irrigate leaves during photosynthesis are demonstrated to be strikingly more abundant in flowering plants than in any other vascular plant lineage. Angiosperm vein densities average 8 mm of vein per mm2 of leaf area and…

Leaf evolution in Southern Hemisphere conifers tracks the angiosperm ecological radiation

Biffin, E., Brodribb, T. J., Hill, R. S., Thomas, P., and Lowe, A. J. (2012). Leaf evolution in Southern Hemisphere conifers tracks the angiosperm ecological radiation. Proceedings of the Royal Society of London Series B 279: 341–348.

The angiosperm radiation has been linked to sharp declines in gymnosperm diversity and the virtual elimination of conifers from the tropics. The conifer family Podocarpaceae stands as an exception with highest species diversity in wet equatorial forests. It…
