Chemical composition of cell wall changes during developmental stages of galls on Matayba guianensis (Sapindaceae): perspectives obtained by immunocytochemistry analysis.

The development of plant organs depends on cell division, elongation, structural and chemical changes, and reorganization of cell wall components. As phenotype manipulators, galling insects can manipulate the structure and metabolism of host tissues to build the gall. The gall formation depends on the rearrangement of cell wall components to allow cell growth and elongation, key step for the knowledge regarding gall development, and shape acquisition.
