↵a Several genes are represented by more than one EST on the arrays.
↵b Data published in Hertzberg et al. (2001). Yes/no, Gene was/was not up-regulated in the D zone; NA, not available because the EST was not represented on the array.
↵c Expression data for rows 1 and 2 have been published in Djerbi et al. (2004). Xy, Xylem; Ph, phloem.
