Oranges are an important nutritional source for human health and have immense economic value. Here we present a comprehensive analysis of the draft genome of sweet orange (Citrus sinensis). The assembled sequence covers 87.3% of the estimated orange genome, which is relatively compact, as 20% is composed of repetitive elements. We predicted 29,445(More)
F-box proteins are a large family of eukaryotic proteins that contained a conserved motif of approximately 40 amino acids. They play an important role in the processing of degradation of cellular regulatory proteins. In this study we isolated a full-length of cDNA encoding a putative F-box protein from Citrus grandis Osbeck CV 'Zigui shatian' pummelo and(More)
BACKGROUND Fusarium wilt, caused by the fungal pathogen Fusarium oxysporum f. sp. cubense (Foc), is one of the most destructive diseases of banana. Toxins produced by Foc have been proposed to play an important role during the pathogenic process. The objectives of this study were to investigate the contamination of banana with toxins produced by Foc, and to(More)
The aim of this study was to develop a large set of microsatellite markers based on publicly available BAC-end sequences (BESs), and to evaluate their transferability, discriminating capacity of genotypes and mapping ability in Citrus. A set of 1,281 simple sequence repeat (SSR) markers were developed from the 46,339 Citrus clementina BAC-end sequences(More)
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(More)
Pummelo (Citrus grandis) is one of the most important species found in the genus Citrus and one of the ancestors of sweet oranges. We used flower buds at different developmental stages to construct the first cDNA library for this species. A total of 3,758 EST sequences were generated from the cDNA library and clustered into 2,228 unigenes, comprising 451(More)
The nucleotide-binding site leucine-rich repeat (NBS-LRR) genes are the largest class of disease resistance genes in plants. However, our understanding of the evolution of NBS-LRR genes in Rutaceae fruit crops is rather limited. We report an evolutionary study of 103 NBS-encoding genes isolated from Poncirus trifoliata (trifoliate orange), Citrus reticulata(More)
Sweet orange (Citrus sinensis) is one of the major cultivated and most-consumed citrus species. With the goal of enhancing the genomic resources in citrus, we surveyed, developed and characterized microsatellite markers in the ≈347 Mb sequence assembly of the sweet orange genome. A total of 50,846 SSRs were identified with a frequency of 146.4 SSRs/Mbp.(More)
The development of organized, informative, robust, user-friendly, and freely accessible molecular markers is imperative to the Musa marker assisted breeding program. Although several hundred SSR markers have already been developed, the number of informative, robust, and freely accessible Musa markers remains inadequate for some breeding applications. In(More)
Plants contain a range of aquaporin (AQP) proteins, which act as transporter of water and nutrient molecules through living membranes. AQPs also participate in water uptake through the roots and contribute to water homeostasis in leaves. In this study, we identified 59 AQP genes in the B. rapa database and Br135K microarray dataset.
