Phenotypic Characterization of 35S:CsFUL1 in Long-Fruited Inbred Line R1407 Harboring the A Allele.

(A) to (D) Representative fruits of three CsFUL1^A and CsFUL1^C overexpression lines at 10 DAA (A, C) and at maturity (>30 DAA) (B, D). Bars = 5 cm. V/C, empty vector/control plants.

(E) and (F) CsFUL1 expression in young fruits of CsFUL1^A (E) and CsFUL1^C overexpression lines (F). Three independent samples from different plants were used for expression analysis. Values are means ± se.

(G) and (H) Fruit length quantification of CsFUL1^A (G) and CsFUL1^C overexpression lines (H). Values are means ± se (n = 4 fruits from different plants).

(I) and (J) Longitudinal sections of the fruit pericarp at maturity in CsFUL1^A overexpression lines. Bars = 200 µm.

(K) Cell area in the fruit pericarp in CsFUL1^A overexpression lines. Values are means ± se (n = 3 pericarps from different fruits).

Significance analysis was conducted with the two-tailed Student's t tests (*P < 0.05; **P < 0.01).
