Would a 'World Tree' be feasible in real life?

A livescience.com article claims that trees can reach a theoretical height of 400 to 426 feet (122 to 130m). This is due to the tree being unable to carry water up to the top at that certain point due to gravity. It also claims that

at a certain height, leaves (or, in the case of redwoods, needles) are not cost-effective "” the energy they rein in through photosynthesis doesn't pay for the energy it costs to bring them water

I'm interested in designing a tree that's much taller than 130 meters. Specifically, I'm interested in creating a titanic "world tree" that exceeds the theoretical height limit. The world tree would have a ludicrous amount of leaves for photosynthesis.

Provided the perfect conditions for growth, what methods could the tree use to ferry the water upwards? And what would the limit be in that case? I'm assuming that there are other factors that could limit tree growth besides the inability to ferry water to the top of the tree; for example, after a certain height the wood of the tree may collapse on itself.

To be slightly clearer, I would like a list of evolutions/adaptations that would allow this tree to exist under perfect conditions and stability and what its height limit would be in that case. I can understand that such a tree with conventional earth trees impossible, that the limitations of wood would debilitate its height, and that it would not go over the troposphere due to temperature and air conditions

Thanks for the answers,tho I don't think I'll be messing with the gravity

Thanks to Brythan and Hamlet for the edits :D
