In the stems of terrestrial vascular plants studied to date, the diameter of xylem water‐
conducting conduits D widens predictably with distance from the stem tip L approximating …

Green plants are Earth's primary solar energy collectors. They harvest the energy of the Sun
by converting light energy into chemical energy stored in the bonds of sugar molecules. A …

Despite the crucial role of carbon transport in whole plant physiology and its impact on plant–
environment interactions and ecosystem function, relatively little research has tried to …

Abstract Purpose of Review This review shows that a more or less constant rate of tip-to-
base vessel widening across species, together with the assumption that wider vessels are …

Not long ago, textbooks on plant physiology divulged the view that phloem and xylem are
separate transport systems with exclusive functions. Phloem was flowing downwards …

X‐ray microdensitometry on annually resolved tree‐ring samples has gained an exceptional
position in last‐millennium paleoclimatology through the maximum latewood density (MXD) …

Key message Environmental cues regulate plant vascular differentiation and plant evolution
through simple hormonal mechanisms of a single or a few moving signals. Abstract …

Flowering plants predominantly conduct water in tubes known as vessels, with vessel
diameter playing a crucial role in plant adaptation to climate and reactions to climate …

The hydraulic properties of xylem and phloem differ but the magnitude and functional
consequences of the differences are not well understood. Phloem and xylem functional …

Trees present a critical challenge to long-distance transport because as a tree grows in
height and the transport pathway increases in length, the hydraulic resistance of the …
