Anatomical features of water-transporting xylem conduits in the leaves of wild-type (Col-0) A. thaliana and a tocopherol-deficient mutant (vte1) grown at hot temperatures (36 °C).

	Water Conduit Number per Vein *	Individual Water Conduit Cross-Sectional Area, µm2 **
Col-0 wild-type	8.0 ± 0.5	23.8 ± 1.7
Tocopherol-deficient vte1 mutant	10.5 ± 0.4	20.5 ± 0.6

Mean values ± standard errors (n = 4 to 5); significant differences (t-test) indicated by asterisks—* = p < 0.05, ** = p < 0.01. Data from Stewart et al. [71].
