Restricted cell elongation in Arabidopsis hypocotyls is associated with a reduced average pectin esterification level

open access: yesBMC Plant Biology, 2007
Background Cell elongation is mainly limited by the extensibility of the cell wall. Dicotyledonous primary (growing) cell walls contain cellulose, xyloglucan, pectin and proteins, but little is known about how each polymer class contributes to the cell ...

HvCKX2 gene silencing by biolistic or Agrobacterium-mediated transformation in barley leads to different phenotypes

open access: yesBMC Plant Biology, 2012
Background CKX genes encode cytokinin dehydrogenase enzymes (CKX), which metabolize cytokinins in plants and influence developmental processes. The genes are expressed in different tissues and organs during development; however, their exact role in ...
