Expression pattern of the PDI8 _pro :GUS reporter construct in seedlings and flowering plants. GUS staining pattern of 7-day-old seedlings (a), with close-up images of a cotyledon stomata (so) and vasculature (v) (b), the root mature zone (c), and the root tip (d). GUS staining pattern of 14-day-old seedlings (e), with close-up images of an expanding leaf (f) and the shoot apex (g). In panel g, the emerging leaves were pulled back to expose the shoot apical meristem (sm). GUS staining pattern of 6-week-old plants in flowers (h), an expanding silique (i), and the inflorescence stem (j). In j, staining is shown at the junction between the stem (st) and the pedicel (pd) of a silique
