Fractions of Fe and Mn in Arabidopsis thaliana dry and imbibed seed.

El.	Dry		Imbibed
	% metal	% area	% metal	% area
Fe	50.7 ± 11.2	13.4 ± 5.4	68.9 ± 5.8	17.1 ± 1.5
Mn	30.3 ± 7.0	8.3 ± 6.0	54.4 ± 2.8*	22.4 ± 7.3

The fractions of Fe and Mn quantified in their corresponding enriched areas relative to the whole seed section element content were calculated for dry and imbibed seed. Proportion of each enriched area was also calculated. Values are means ± SE (n = 3–4 scanned sections). Asterisk denotes statistically significant differences based on Mann–Whitney U test (p < 0.05).
