简介:Citrus somatic hybrids produced in the past years provide a novel opportunity to study the immediate effects of allopolyploidization on genome structure and methylation. Here, we present a first attempt to investigate the alterations in genome structure and methylation in three sets of citrus somatic allotetraploids and their diploid parents using amplified fragment length polymorphism (AFLP) and ...

简介:The Consortium of Barcode of Life plant working group proposed to use the defined portion of plastid genes rbcL and matK either singly or in combination as the standard DNA barcode for plants. But DNA barcode based identification of biologically complex plant groups are always a challenging task due to the occurrence of natural hybridization. Here, we examined the use of indels polymorphism in trn...

简介:Key message Xanthomonas citri subsp. citri pretreatment before agroinfiltration could significantly promote transient expression in citrus leaves which were previously recalcitrant to agroinfiltration. Transient expression via agroinfiltration is widely used in biotechnology but remains problematic in many economically important plants. Xanthomonas citri subsp. citri (Xcc)-facilitated agroinfiltra...

简介:Citrus, and particularly sweet oranges, are very recalcitrant to anther culture. In this paper it was evaluated for the first time the response of 27 genotypes of Citrus sinensis and of one hybrid C. clementina x C. sinensis, to in vitro anther culture. Ten genotypes of sweet oranges showed embryogenic callus induction, mostly blood sweet oranges genotypes, such as Tarocco, Moro and Sanguinelli. I...

简介:To improve the resistance of citrus to canker disease caused by Xanthomonas axonopodis pv. citri (Xac), it is important to identify gene promoters that are specifically induced by pathogen infection. Here, we evaluated the functionality of PPP1 and hsr203J (Nicotiana tabacum L.) and gst1 (potato) pathogen-inducible promoters to drive expression of the beta-glucuronidase (GUS) reporter gene in tran...

简介:Seedlessness, an important economic trait for fresh fruit, is among the prior goal for all citrus breeding programs. Symmetric somatic hybridization provides a new strategy for citrus seedless breeding by creating cybrids transferring mitochondrial DNA (mtDNA) controlled cytoplasmic male sterility (CMS) from the callus parent Satsuma mandarin (C. unshiu Marc.) to seedy cultivars. In this study, pr...
