Nature Reviews Genetics 9, 433–443 (2008)

I am retracting this invited Nature Reviews Genetics article due to a paragraph being paraphrased without attribution. The paragraph in question was from an early version of an article to which I had access as a peer reviewer and which has since been published in Plant Science (Abramson, M., Shoseyov, O. & Shani, Z. Plant cell wall reconstruction toward improved lignocellulosic production and processability. Plant Sci. 178, 61–72 (2010)). I regret this error and wish to apologize to the authors of the Plant Science article.
