¹All quantities were normalized to the level of expression obtained for Col shoot. GL1 and HSP70 values were normalized separately. Mean ± standard deviation values are shown derived from 2 replicates of each tissue.

²All young shoot tissue contained just the apex and emerging leaves that lacked petioles.

³Third leaves were dissected from seedlings just at the stage when the leaves were beginning to develop petioles.

⁴All reaction conditions and primers are described in Marks et al., 2007.

⁵The HSP70 gene was used an internal control of mRNA integrity, as previous analyses have shown that the expression of this gene varies little from tissue to tissue under normal growth conditions.
