简介:A parthenocarpy gene(DefH9-iaaM)was introduced into Succari to obtain possible seedless transformants, by using internodal stem segments as explants to establish an efficient regeneration and transgenic system.The results indicated that 30-day-old seedlings were the most efficient explants.The co-culture in darkness for 3~6 days gave a rise to good regeneration.The optimum medium for adventitious ...

简介:After establishing the regeneration and transformation systems of citrus, the TERF1 gene was mediated into ssweetorange byEHA105 and LB4404Agrobacterium tumefaciens. Seven plantswere verified by PCR and RT-PCR amplification. The results showed that EHA105 had more efficiency in improving the transgenic ratio than LBA440

简介:Floral nectar chemical composition of conventional and transgenic sweet orange trees expressing the antibacterial peptide sarcotoxin IA (Stx IA), which has been shown to efficiently inhibit in vitro growth of the bacteria responsible for citrus canker (Xanthomonas axonopodis pv. citri), is reported. The nectar contents of primary metabolites (sugars, amino acids, proteins, triacylglycerides) and o...

简介:Quantitative real-time PCR(qRT-PCR) was adapted to estimate transgene copy number of the rice Xa21 gene in transgenic citrus plants. This system used TaqMan qRT-PCR and the endogenous citrus gene encoding for lipid tansfer protein(LTP). Transgenic 'Hamlin' sweet orange plants were generated using two different protoplast-GFP transformation systems: cotransformation and single plasmid transformatio...

简介:Background: Citrus species constitute one of the major tree fruit crops of the subtropical regions with great economic importance. However, their peculiar reproductive characteristics, low genetic diversity and the long-term nature of tree breeding mostly impair citrus variety improvement. In woody plants, genomic science holds promise of improvements and in the Citrus genera the development of ge...

简介:Grapefruit (Citrus paradisi) transgenic plants transformed with a variety of constructs derived from the Citrus tristeza virus (CTV) genome were tested for their resistance to the virus. Most transgenic lines were susceptible (27 lines), a few were partially resistant (6 lines) and only one line, transformed with the 30 end of CTV was resistant. Transgene expression levels and siRNA accumulation w...

简介:Genetic transformation of mature trees is difficult because adult tissues are recalcitrant to Agrobacterium tumefaciens infection and transformation and because transgenic mature events are less competent for regeneration. We have shown that reinvigoration allows manipulation of the vegetative phase to increase the potential for transformation and regeneration without loss of competence for flower...

简介:The objective of this work was to establish tissue culture parameters for gene transfer in sweet orange cultivars. Epicotyl explants with different ages were cultured with 6-benzylaminopurine (BAP), kanamycin and hygromycin. Shoots were cultured with alpha-naphthaleneacetic acid (NAA) alone or in combination with indole-3-butyric acid (IBA). The requirement of BAP for shoot development was genotyp...

简介:Background: During the last decade, numerous microsatellite markers were developed for genotyping and to identify closely related plant genotypes. In citrus, previously developed microsatellite markers were arisen from genomic libraries and more often located in non coding DNA sequences. To optimize the use of these EST-SSRs as genetic markers in genome mapping programs and citrus systematic analy...

简介:Malate, ubiquitously existing in plan,t plays a crucial role in variousmetabolic pathways, including respiration, nitrogen fixation, phosphorus acquisition, and aluminum tolerance. Malate dehydrogenase(MDH) catalyzes the interconversion ofoxaloacetate andmalate. Previous results suggested that overexpressing MDHgene transgenic plants elevated tolerance to aluminum toxicity.Citrus junos, one ofmain...

简介:In order to improve transformation efficiency in citrus two green fluorescent protein (GFP) constructions, an endoplasmic reticulum targeted (GFP-ER) and cytoplasmic targeted (Cy-GFP), were used to study expression and stability of GFP in transgenic plants. Results from citrus protoplast-GFP transformation showed that GFP-ER had brighter fluorescence than the Cy-GFP. Although both of these constru...

简介:Harmless bacteria inhabiting inner plant tissues are termed endophytes. Population fluctuations in the endophytic bacterium Pantoea agglomerans associated with two species of field cultured citrus plants were monitored over a two-year period. The results demonstrated that populations of P. agglomerans fluctuated in Citrus reticulata but not C. sinensis. A cryptic plasmid pPA3.0 (2.9 kb) was identi...

简介:An improved method for the Agrobacterium infiltration of epicotyl segments of ‘Pineapple’ sweet orange [Citrus sinensis (L.) Osbeck] and ‘Swingle’ citrumelo [Citrus paradisi Macf. X Poncirus trifoliata (L.) Raf.] was developed in order to increase transformation frequency. Sonication-assisted Agrobacterium-mediated transformation (SAAT), vacuum infiltration, and a combination of the two proced...
