“…Poncirus and Microcitrus were quite distant from Citrus (high bootstrap values), while Fortunella was more closely related. This analysis supported the phylogenetic relationships in the Citrinae established using other markers (Nicolosi et al, 2000;Garcia-Lor et al, 2013a, 2013bPenjor et al, 2013;Ramadugu et al, 2013) but did not reveal the distinct phylogenetic cluster of citron and Microcitrus established using the complete chloroplast DNA of 34 species (Carbonell-Caballero et al, 2015).…”

“…Sweet orange (C. sinensis) is considered a complex hybrid involving mandarin (providing the predominant genetic material) and pummelo (Garcia-Lor et al, 2013b;Xu et al, 2013;Wu et al, 2014), and the allelic composition of the Ruby locus (r TATA and r DEL2 ) confirmed this. We have been unable to detect any expression of Ruby in different tissues of common varieties of sweet orange (Butelli et al, 2012), consistent with the complete absence of anthocyanin pigmentation.…”

Changes in Anthocyanin Production during Domestication of Citrus

Mandarin (Citrus reticulata), citron (Citrus medica), and pummelo (Citrus maxima) are important species of the genus Citrus and parents of the interspecific hybrids that constitute the most familiar commercial varieties of Citrus: sweet orange, sour orange, clementine, lemon, lime, and grapefruit. Citron produces anthocyanins in its young leaves and flowers, as do species in genera closely related to Citrus, but mandarins do not, and pummelo varieties that produce anthocyanins have not been reported. We investigated the activity of the Ruby gene, which encodes a MYB transcription factor controlling anthocyanin biosynthesis, in different accessions of a range of Citrus species and in domesticated cultivars. A white mutant of lemon lacks functional alleles of Ruby, demonstrating that Ruby plays an essential role in anthocyanin production in Citrus. Almost all the natural variation in pigmentation by anthocyanins in Citrus species can be explained by differences in activity of the Ruby gene, caused by point mutations and deletions and insertions of transposable elements. Comparison of the allelic constitution of Ruby in different species and cultivars also helps to clarify many of the taxonomic relationships in different species of Citrus, confirms the derivation of commercial varieties during domestication, elucidates the relationships within the subgenus Papeda, and allows a new genetic classification of mandarins.

“…In Citrus, recently, a rough draft of the genome was completed using the haploid Clementine mandarin and the doubled haploid sweet orange (Ollitrault et al, 2012;Xu et al, 2013). This genomic information has also been applied for the development of DNA markers, genetic analysis, and the production of new cultivars (Ahmad et al, 2013;Cuenca et al, 2013;Garcia-Lor et al, 2013). Our doubled haploid pummelo will also be utilized as alternative material for these genetic and breeding studies.…”

Morphological Characteristics of a Doubled Haploid Line from ‘Banpeiyu’ Pummelo [<i>Citrus maxima</i> (Burm.) Merr.] and Its Reproductive Function

et al. 2015

To obtain basic information about doubled haploid plants in Citrus, in the present study, we investigated the morphological characteristics in doubled haploid induced by colchicine-treated axillary shoot buds of a haploid plant from 'Banpeiyu' pummelo [C. maxima (Burm.) Merr.]. We also evaluated the reproductive potential of the doubled haploid as a male or a female parent by crossing with some diploids. In term of the results, this doubled haploid had significantly large leaf, flower and fruit compared with those of the original haploid plant. Moreover, the doubled haploid showed higher pollen fertility (84.1% stainability and 32.9% pollen germination rate) and a larger number of seeds (47.2 developed seeds per open-pollinated fruit) than the haploid. In the reciprocal crosses between the doubled haploid and some diploids, many developed seeds were obtained. These seeds germinated normally and developed into diploid seedlings. These results show that the doubled haploid will be valuable for genetic analysis and possibly for planned breeding.

“…Similarly, Luro et al (1995) found high polymorphism among mandarin genotypes using microsatellite (SSR) markers. Additionally, mandarins contained a large number of genetic polymorphisms in many studies that were performed to clarify the diversity and taxonomy of Citrus (Nicolosi et al, 2000;Luro et al, 2001;Barkley et al, 2006;Ollitrault et al, 2012;Garcia-Lor et al, 2013). Simsek et al (2011) reported that mandarins have high allelic diversity in iron chlorosis tolerance genes (Fe-S assembly protein and irt1).…”
