Gibberellins Enhance Cell Wall Extensibility without Acidification. Gibberellin has no effect on the osmotic parameters but has consistently been observed to cause an increase in both the mechanical extensibility of cell walls and the stress relaxation of the walls of living cells. the enzyme Expansins and Xyloglucan endotransglycosylase (XET) is involved in gibberellin-promoted wall extension. The function of XET may be to facilitate the penetration of expansins into the cell wall.

Form I is the only type of Rubisco that harbors small subunits, and it consists of eight large and eight small subunits [L8S8]: Four dimers of large subunits [L2]4 capped by four small subunits at the top and the bottom [S4]2 build the hexadecameric structure {[S4]•[L2]4•[S4] = L8S8}
