35S:TM8:SRDX plant phenotype. (A) Wild-type tomato plant (left) and plant of the line 35S:TM8:SRDX#2 (right) over-expressing TM8:SRDX and having a marked leaf epinasty (see insert). (B) Chlorophyll A and B content in wild-type (white) and 35S:TM8:SRDX (grey) leaves. Values represent the mean of three different transgenic lines and two untransformed plants. Bars are the standard deviations from the means. Asterisks indicate values significantly different by Student’s t test from the control (P <0.05). Wild-type tomato inflorescence (C) and inflorescence of the line 35S:TM8:SRDX#6 (D), the latter having longer flower peduncles. ESEM (environmental scanning electron microscopy) pictures of a wild-type flower abscission zone (E) and of the anomalous flower abscission zone of the line 35S:TM8:SRDX#2 (F). ESEM pictures of a wild-type ovary (G) and of the oblong ovary of the line 35S:TM8:SRDX#2 (H). Wild-type fruits (I, K) and fruits of the line 35S:TM8:SRDX#6 having an oblong morphology (J) and bearing no seeds (L).
