plants have the ability to fix 2 or 3 times more carbon with the same

Sorry about the C4/CAM confusion. It has been many years since I

Water-use efficiency is not synonymous with drought tolerance - it's a
measure of the amount of biomass a plant can make while

Well, Wayne, wouldn't you consider C4 metabolism to be a form of drought
tolerance that doesn't require restriction of biomass production? C4
plants can open their stomata at night, when water loss will be less than
during the day, absorb C02 and store it in the C4 molecule. When the sun
rises

Ecolog:
What IS drought tolerance?
What evidence is there that plants can manufacture more biomass/crop yield
on less water rather than to evade water deficits by continuing to survive

C4 metabolism (also known as Crassulacean acid metabolism) is accomplished
by special biochemical pathways which have their basis in genetics. Since
