Tyloses and phenolic deposits in xylem vessels impede water transport in low-lignin transgenic poplars: a study by cryo-fluorescence microscopy

Creator:

Kitin, Peter, Voelker, Steven L., Meinzer, Frederick C., Beeckman, Hans, Strauss, Steven H., and Lachenbruch, Barbara

Abstract:

Of 14 transgenic poplar genotypes (Populus tremula × Populus alba) with antisense 4-coumarate:coenzyme A ligase that were grown in the field for 2 years, five that had substantial lignin reductions also had greatly reduced xylem-specific conductivity compared with that of control trees and those transgenic events with small reductions in...

Transgenic poplars with reduced lignin show impaired xylem conductivity, growth efficiency and survival

Creator:

Voelker, Steven L., Lachenbruch, Barbara, Meinzer, Frederick C., Kitin, Peter, and Strauss, Steven H.

Abstract:

We studied xylem anatomy and hydraulic architecture in 14 transgenic insertion events and a control line of hybrid poplar (Populus spp.) that varied in lignin content. Transgenic events had different levels of down‐regulation of two genes encoding 4‐coumarate:coenzyme A ligase (4CL). Two‐year‐old trees were characterized after growing either as free‐standing...
