简介:柠檬苦素类似物是引起柑橘苦味的主要原因之一,柑橘的苦味对柑橘果实的鲜食和加工品质有明显不利影响。此外,柠檬苦素类似物具有抗肿瘤、抗炎、镇痛、昆虫拒食等很多药理活性。由于柠檬苦素类似物具有这些功能,所以柠檬苦素类似物的需求日益增加,但是苦味的存在限制了人们对它的摄取。柠檬苦素类似物配糖体具有水溶性且无苦味等特性,其生物学活性和柠檬苦素类似物是相似的。因而将其作为替代性食品添加剂,有很好的市场前景。 本研究...

简介:This study was aimed to optimize the organogenesis in rough lemon (Citrus jambhiri Lush), an important citrus rootstock of India. Organogenesis was induced in epicotyl segments of rough lemon seedlings. Three important factors influencing organogenesis in vitro viz. hormone combination, cut modes and photoperiod were evaluated. Etiolation of seedlings had a positive effect on bud formation and hig...

简介:The lack of naturally occurring resistance to Citrus psorosis virus (CPsV) has demanded exploitation of a transgenic approach for the development of CPsV-resistant sweet orange plants. Transgenic sweet orange plants producing intron-hairpin RNA transcripts (ihpRNA) corresponding to viral cp, 54K or 24K genes were generated and analyzed at the molecular and phenotypic levels. Two independent CPsV c...

简介:Agrobacterium-mediated transformation in Satsuma mandarin (Citrus unshiu Marc.) cv. Miyagawa wase was achieved with reasonable transformation efficiency of about 22%, which was the percentage of transgenic plantlets confirmed by genomic PCR (37 plantlets/168 hygromycin-resistant calli). Embryogenic calli of Miyagawa wase were infected with Agrobacterium tumefaciens strain EHA105 harboring binary v...

简介:Miraculin is a taste modifying plant protein, which displays a peculiar property of being able to modify sour taste into sweet taste. Thus, there has been an increasing interest in miraculin due to this amazing property. In the present study, miraculin gene was introduced into the Miyagawa Wase Satsuma mandarin (Citrus unshiu Marc.) callus by Agrobacterum-mediated transformation to produce a citru...

简介:Background/Objective: Despite potential benefits granted by genetically modified (GM) fruit trees, their release and commercialization raises concerns about their potential environmental impact, and the transfer via pollen of transgenes to cross-compatible cultivars is deemed to be the greatest source for environmental exposure. Information compiled from field trials on GM trees is essential to pr...

简介:The T36 strain of citrus tristeza virus (CTV) expressing green fluorescent protein gene (CTVeGFP) was used to detect replication of CTV in wild-type (WT) ‘Hamlin’ sweet orange plants and those transformed with the use of Agrobacterium tumefaciens strain harboring a binary vector with a coat protein gene from either T36 or T30 isolate of CTV. Soil-adapted WT and transgenic plants were challenged ...

简介:The objective of this study was to improve shoot regeneration from grapefruit. Because many commercially grown citrus types are apomictic, important in vitro applications such as Agrobacterium-mediated transformation commonly use epicotyl explants from in vitro seedlings; thus, adequate adventitious shoot production is an important prerequisite for efficient use of these applications. Eight plant ...

简介:Genetic transformation is considered an important tool to be applied in citrus genetic improvement. However, transformation efficiency may vary according to several factors, including the genetic construction utilized. This study was carried out to evaluate the efficiency of genetic transformation of ‘Carrizo’ citrange [Poncirus trifoliata (L.) Raf. x Citrus sinensis (L.) Osbeck], containing two...

简介:Background: Enormous work has shown that polyamines are involved in a variety of physiological processes, but information is scarce on the potential of modifying disease response through genetic transformation of a polyamine biosynthetic gene.
Results: In the present work, an apple spermidine synthase gene (MdSPDS1) was introduced into sweet orange (Citrus sinensis Osbeck ‘Anliucheng’) via Agr...

简介:Trifoliate orange (Poncirus trifoliata L. Raf.), a rootstock widely used for citrus species, is salt-sensitive. Worldwide, salinity is a major abiotic stress affecting citrus growth and yield. Glycinebetaine (GB) is an important osmoprotectant involved in responses to salt stress. However, current evidence regarding the effect of salt stress on GB accumulation in trifoliate orange is limited, and ...

简介:In this study, we present a method for transient expression of the type III effector AvrGf1 from Xanthomonas citri subsp. citri strain Aw in grapefruit leaves (Citrus paradisi) via Agrobacterium tumefaciens. The coding sequence of avrGf1 was placed under the control of the constitutive CaMV 35S promoter in the binary vectors pGWB2 and pGWB5. Infiltration of grapefruit leaves with A. tumefaciens ca...

简介:In transgenic plants, multiple T-DNA copies and cytosine methylation usually correlate with a loss of transgene expression while methylation of promoter is associated with transgene silencing. Here, six independent GFP transgenic ‘Bingtang’ sweet orange (Citrus sinensis (L.) Osb.) plants were analyzed with copy number, T-DNA repeat, cytosine methylation and transgene expression. The fluorescence...

简介:Four antioxidants including glycine betaine, glutathione, lipoic acid, and polyvinylpyrrolidone were evaluated to improve transformation efficiency of Mexican lime, a precocious but recalcitrant citrus cultivar to Agrobacterium mediated transformation. Lipoic acid substantially improved the transformation efficiency of Mexican lime by aiding in callus development and improving shoot growth from cu...
