Fig. 4. Comparison of seeds generated by wild-type and mnt mutant plants. (A-D) Seeds from pollinations where all secondary shoots were allowed to set seed; (E-H) seeds from pollinations where secondary shoots were removed (see text). (A,E) [wild type x wild type]; (B,F) [wild type x mnt]; (C,G) [mnt x mnt]; (D,H) [mnt x wild type]. Scale bar: 250 µm. (I) Comparison of seed weights following the two treatments. Error bars: s.e.m.
