“…It originates from Barbados in the Caribbean islands and was first named as Citrus paradisi Macf. by James Macfedyan in 1837 (Scora et al, 1982;Scora, 1988). Grapefruits are highly polyembryonic, therefore they are of nucellar and mutation origin.…”

Comparative use of InDel and SSR markers in deciphering the interspecific structure of cultivated citrus genetic diversity: a perspective for genetic association studies

Genetic stratification associated with domestication history is a key parameter for estimating the pertinence of genetic association study within a gene pool. Previous molecular and phenotypic studies have shown that most of the diversity of cultivated citrus results from recombination between three main species: C. medica (citron), C. reticulata (mandarin) and C. maxima (pummelo). However, the precise contribution of each of these basic species to the genomes of secondary cultivated species, such as C. sinensis (sweet orange), C. limon (lemon), C. aurantium (sour orange), C. paradisi (grapefruit) and recent hybrids is unknown. Our study focused on: (1) the development of insertion-deletion (InDel) markers and their comparison with SSR markers for use in genetic diversity and phylogenetic studies; (2) the analysis of the contributions of basic taxa to the genomes of secondary species and modern cultivars and (3) the description of the organisation of the Citrus gene pool, to evaluate how genetic association studies should be done at the cultivated Citrus gene pool level. InDel markers appear to be better phylogenetic markers for tracing the contributions of the three ancestral species, whereas SSR markers are more useful for intraspecific diversity analysis. Most of the genetic organisation of the Citrus gene pool is related to the differentiation between C. reticulata, C. maxima and C. medica. High and generalised LD was observed, probably due to the initial differentiation between the basic species and a limited number of interspecific recombinations. This structure precludes association genetic studies at the genus level without developing additional recombinant populations from interspecific hybrids. Association genetic studies should also be affordable at intraspecific level in a less structured pool such as C. reticulata.

“…The first subgroup includes grapefruit (C. paradisi) cultivars, the mandarin cultivar 'Okitsu Wase' (C. unshiu), pummelo (C. grandis) cultivars, 'Ichang lemon' (C. ichangensis  unknown cultivar of C. grandis) and 'Samboukan' (C. sulcata). It has been suggested that grapefruit is derived from a sweet orange and pummelo hybrid (Scora, 1975;Barrett and Rhodes, 1976;Scora et al, 1982 Scora andKumamoto, 1983;Nicolosi et al, 2000). The strong similarity between grapefruit cultivars and those of pummelo was indicated in our analysis, whereas no similarity was observed between grapefruit and sweet oranges.…”

Citrus taxonomy is very complex and confusing, because of asexual reproduction and sexual compatibility between Citrus and related genera. Metabolic diversity was studied in Citrus, Poncirus and Fortunella cultivars by the high performance liquid chromatography technique combined with multivariate statistical analysis. Chromatograms obtained from cultivars of the same species showed similar elution profiles. These results suggested that metabolic profiles carry characteristics of hybrid origin. To confirm the similarities among the Citrus species and their cultivars, multivariate statistical analysis was applied to the chromatograms. According to hierarchical cluster analysis, all cultivars used in this study were divided into three major groups, which largely correspond to pummelo, mandarin and lemon. Hybrids were clustered together with their hybrid origin or their related cultivars. Our results indicated that the metabolic fingerprinting method provides an insight into the phylogenic relationships among Citrus species and cultivars.
