Graft - transmissible action of JcFT to reduce flowering time of other genetically modified Jatropha plants. (A) Comparison of flowering time of high oleic acid (X8-34) transgenic Jatropha shoot grafted to root stock of WT or JcFT-overexpressing plants. Flowering time refers to the number of days from the day of grafting to the day of emergence of the first inflorescence. (B) Flowering time of high oleic acid (X8-34) transgenic Jatropha not affected by grafting on WT Jatropha root stock. White arrow indicates the grafting site. (C) Flowering time of high oleic acid (X8-34) transgenic Jatropha was reduced by grafting onto JcFT transgenic T1 plant (#43) root stock. White arrow indicates the grafting site. (D) Comparison between plants grafted to WT control root stock and JcFT #43 root stock. (D), WT control root stock. (E) and (F), JcFT # 43 root stock. (F) Enlarged view of sympodial unit structure. LS: lateral shoots. Red arrow indicates the first inflorescence. Bar: 10 cm.
