简介:Citrus FT (CiFT) cDNA, which promoted the transition from the vegetative to the reproductive phase in Arabidopsis thaliana, when constitutively expressed was introduced into trifoliate orange (Poncirus trifoliata L. Raf.). The transgenic plants in which CiFT was expressed constitutively showed early flowering, fruiting, and characteristic morphological changes. They started to flower as early as 1...

简介: Protoplast fusion can circumvent reproductive barriers facing citrus, such as polyembryony and female and/or male sterility, and paves way for citrus cultivar improvement. Two kinds of fusion patterns were employed for citrus, leaf-derived protoplasts + embryogenic callus protoplasts and embryogenic callus protoplasts + embryogenic callus protoplasts. More than 200 cases of somatic hybrids have b...

简介:The use of edible for the production and delivery of vaccine could provide an economical alternative to systems. The construction of the plant expression vector pBI121-A was reported, which contained a fusion gene encoding A . The gene was located between the left and right Ti border sequences under the control of CaMV35S promoter. The vector was identified via PCR and restriction enzyme analysis ...

简介:Intergeneric somatic hybrids combining Goutou sour orange (Citrus aurantium L.) with trifoliate orange [Poncirus trifoliata (L.) Raf] were produced by electrofusion and their genetic inheritance analyzed by amplified fragment length polymorphism (AFLP), genomic in situ hybridization (GISH), and PCR-restriction fragment length polymorphism (PCR-RFLP). Sixteen mini-calluses were obtained after 20 da...

简介:Most commercial citrus fruit species and cultivars are inter- and intra-specific hybrids. Conventional hybridization in citrus is largely handicapped by apomixis and long juvenility. As an alternative, somatic hybridization via protoplast fusion has been employed to create novel citrus germplasm. Witches' broom disease of lime (WBDL) emerged in Oman during the 1970s, which has been spreading to th...
