cellular elongation: as the cell wall is
partially degraded by the

expansins have been identified: α-
expansins, β-
expansins, and
bacterial expansins.
There are
still numerous unanswered questions regarding expansins and...

acidification of the cell wall
region activates enzymes known as
expansins which disrupt hydrogen bonds in the cell wall structure,
making the cell...
