This review showed that lign<strong>in</strong> biosyn<strong>the</strong>sis <strong>in</strong> nature can <strong>in</strong>crease complexity<br />
depend<strong>in</strong>g on <strong>the</strong> <strong>stresses</strong> <strong>and</strong> whe<strong>the</strong>r <strong>the</strong> stressor is act<strong>in</strong>g dur<strong>in</strong>g plant growth <strong>and</strong><br />
development. Unfortunately, little has been done to elucidate how such stress<strong>in</strong>g<br />
situations can change lign<strong>in</strong> content or alter its composition with regard to <strong>the</strong> build<strong>in</strong>g<br />
blocks called monolignols, or o<strong>the</strong>r phenolics enter<strong>in</strong>g <strong>the</strong> polymeric structure. Reaction<br />
wood has proven to be an important model for underst<strong>and</strong><strong>in</strong>g lign<strong>in</strong> formation <strong>in</strong> plants<br />
(Mellerowicz <strong>and</strong> Sundberg, 2008). O<strong>the</strong>r <strong>stresses</strong> may also become excellent models<br />
that will yield important clues for underst<strong>and</strong><strong>in</strong>g such complex metabolic pathways, as<br />
well as <strong>the</strong> <strong>in</strong>tricacies of genetic <strong>and</strong> metabolic control.<br />
