Weak coordination among petiole, leaf, vein, and gas‐exchange traits across Australian angiosperm species and its possible implications

Close coordination between leaf gas exchange and maximal hydraulic supply has been reported across diverse plant life forms. However, it has also been suggested that this relationship may become weak or break down completely within the angiosperms. We examined coordination between hydraulic, leaf vein, and gas-exchange traits across a diverse group of 35 evergreen Australian angiosperms, spanni...

Surprisingly Weak Coordination between Leaf Structure and Function among Closely-related 1 Tomato Species 2 3

15 Natural selection may often favor coordination between different traits, or phenotypic 16 integration, in order to most efficiently acquire and deploy scarce resources. As leaves are the 17 primary photosynthetic organ in plants, many have proposed that leaf physiology, biochemistry, 18 and anatomical structure are coordinated along a functional trait spectrum from fast, resource-19 acquisit...

Angiosperm leaf vein evolution was physiologically and environmentally transformative.

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 mm(2) of leaf area and can reach 25 mm mm(-2), whereas such high densities are absent from all other plants, living or extinct. Leaves of non-angiosperms have consistently averaged cl...

Investigation of Genetic Variations among Crested Wheatgrass Species Base of Agronomical Traits and Total Leaf Protein

Genetic variations within the species of Agropyron desertorum and 2 varieties of A. cristatum subsp. pectinatum var. imbricatum and A. cristatum subsp. pectinatum var. pectinatum were studied using morphological traits and total protein profiles (with sodium dodecylsulphate polyacrylamide gel electrophoresis). An experiment was conducted in Research Institute of Forests and Rangelands (2012-201...
