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)
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)
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)
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)
Fusarium wilt is one of the most serious threats to banana production worldwide. The disease is caused by the soil-borne fungal pathogen Fusarium oxysporum f. sp. cubense (Foc), especially tropical race 4 (Foc TR4). It has been reported that crop rotation and intercropping of Chinese leek (Allium tuberosum) with banana can effectively reduce incidence of(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)
The present study aims to analyse phylogenetic relationships, using internal transcribed spacer sequence data of ribosomal DNA (rDNA), across 24 Citrus species and close relatives by the evaluation of several parameters such as nucleotide substitution (r), nucleotide diversity (p) and the estimated values of transition/transversion bias (R). The observed(More)
2 n megagametophyte formation plays an important role in polyploidization in polyembryonic citrus and is valuable for plant improvement. Tetraploid plants are frequently observed in the seedlings of diploid polyembryonic citrus genotypes. However, the mechanisms underlying the formation of tetraploids are still indistinct when apomictic citrus genotypes are(More)
