Figure 4: Functional analysis of JcARF19 in Jatropha.
From: Manipulation of Auxin Response Factor 19 affects seed size in the woody perennial Jatropha curcas
(a) Comparison of plant architecture of JcARF19 overexpression transgenic T0 plant (#1, right) with WT Jatropha plant (Jc-MD, left). (b) No inflorescence was found in WT Jatropha plant Jc-MD in the same stage as JcARF19-overexpressing transgenic T0 plant (#1). (c) JcARF19-overexpressing transgenic T0 plant (#1) with early inflorescence. Bar: 10 cm for (a–c). (d,e) Comparison of fruit size of WT Jatropha (Jc-MD, left) and transgenic T1 Jatropha plant overexpressing JcARF19 (right). Bar: 1 cm. (f) Comparison of seed size of WT Jatropha (Jc-MD, left) and transgenic T1 Jatropha plant overexpressing JcARF19 (right). Dashed line indicates the position of the cross-section. Bar: 1 cm. Comparison of cell size of WT Jatropha Jc-MD (g) and transgenic T1 Jatropha plant overexpressing JcARF19 (h). Bar: 50 μm.
