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)
Plant s-phase kinase-associated protein 1 (SKP1) genes have diverse functions in plant developmental and physiological activities. Herein, we described a novel SKP1 gene, designated as CgSKP1, from ‘Shatian’ pummelo (Citrus grandis Osbeck). The cDNA sequence of CgSKP1 was 603 bp and contained an open reading frame of 477 bp. Genomic sequence of the CgSKP1(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)
Homozygous genotypes are valuable for genetic and genomic studies in higher plants. However, obtaining homozygous perennial plants using conventional breeding techniques is currently a challenge because of a long juvenile period, high heterozygosity and the substantial inbreeding depression. In vitro androgenesis has been used to develop haploid and doubled(More)
Somatic embryogenesis was achieved from callus from leaf and nodal segments of strawberry clone pbgel-2000. The highest percent of cultures with somatic embryos was achieved on MS medium supplemented with 1.0 mg/l 2,4-D, 0.5 mg/l BAP and 50% proline. Darkness was the best condition for incubation with daily light periods over 6 h reducing the frequency of(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)
Retro-transposons are common components of plant genomes, functional at transcription, translation and integration levels. Their abundance and ability to transpose render them good potential markers. Present study was undertaken with the view of IRAP (inter-retrotransposon amplified polymorphism) and REMAP (retrotransposon-microsatellite amplified(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)
An analysis of the frequency of occurrence of various residues at position X was carried out on the consensus glycosylating sequence Asn-X-Ser/Thr using the PDB three-dimensional database. 488 non-homologous proteins bearing 696 Asn-X-Ser/Thr (X not equal Pro) sequences were analysed. More than 65% of Asn residues, when they occur as part of the consensus(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)
