CsFUL1^A-RNAi Resulted in Longer Fruits in Inbred Line R1407 with the A Allele.

(A) to (D) Representative fruits at 10 DAA (A, C) and at maturity (B, D) in CsFUL1^A-RNAi and CsFUL1^C-RNAi lines. Bars = 5 cm. V/C, empty vector/control plants.

(E) to (G) CsFUL1 and CsFUL2 expression in young fruits of CsFUL1^A-RNAi plants (E, F) and CsFUL1^C-RNAi plants (G) as detected by RT-qPCR. Three independent samples from different plants were used for expression analysis. Values are means ± se. V/C, empty vector/control plants.

(H) to (J) Fruit length at 10 DAA and at maturity. Values are means ± se (n = 4 fruits). V/C, empty vector/control plants.

(K) and (L) Longitudinal sections of fruits at maturity in control (K) and CsFUL1^A-RNAi (L) lines. Bars = 200 µm. V/C, empty vector/control plants.

(M) Cell area in the fruit pericarp of CsFUL1^A-RNAi plants. Values are means ± se (n = 3 pericarps).

Significance analysis was conducted using two-tailed Student's t tests (*P < 0.05; **P < 0.01). V/C, empty vector/control plants.
