Percent basal MetSO content of isolated chloroplasts from wild-type and transgenic plants underexpressing (35S∷anti-PMSR4) or overexpressing (35S∷PMSR4) PMSR4

		35S∷PMSR4			35S∷anti-PMSR4
	Wild Type	802	202	1001	801	1002	1003
Percent MetSO	28 ± 5	31 ± 13	28 ± 11	27 ± 10	28 ± 5	33 ± 10	27 ± 12

Chloroplasts were isolated from 4-week-old plants grown under optimal growing conditions. The results represent the percentage of MetSO in the total Met pool of the soluble proteins of the chloroplasts and correspond to the mean ± sd of three independent chloroplast preparations of 32 plants each.
