tpj12100-sup-0006-TableS1.xlsxapplication/msexcel2139KTable S1. Genes expressed above background in the guard cell, mesophyll cell and vascular bundle harvested from third and fourth leaves of 1–month-old Arabidopsis plants and in provascular (PV) and procambial (PC) cells from P1 and P2 leaves of 7–day-old Arabidopsis seedlings, compared with levels in Arabidopsis cell culture RNA on the same arrays. Genes (435) expressed in both PV/PC and mature vascular cells; genes (1487) expressed in PV/PC cells but not in mesophyll or guard cells.
