Lemons, limes and citron constitute a group of closely related Citrus species, whose species delimitations and taxonomic relationships are unclear. In order to identify karyotypic similarities and species relationships within this group, the CMA+/DAPI– banding pattern and the distribution of the 5S and 45S rDNA sites of 10 accessions of lime, lemon, and citron were investigated. The four cultivars of C. limon analyzed showed the same pattern of CMA+ bands and rDNA sites, suggesting that they…

Phylogenetic origin of limes and lemons revealed by cytoplasmic and nuclear markers.
TLDR
The lime and lemon horticultural group appears to be highly polymorphic, with diploid, triploid and tetraploid varieties, and to result from many independent reticulation events which defined the sub-groups, as limes and lemons were vegetatively propagated and the intra-sub-group phenotypic diversity results from asexual variations.
The evolution of CMA bands in Citrus and related genera
TLDR
The data suggest that the variable number of terminal CMA+ bands observed on chromosomes of Citrus and related genera are probably the consequence of amplification or reduction in the number of CsSat-like sequences distributed on chromosome termini, paralleled by mutation and homogenization events, as proposed by the library hypothesis.
Chromosome homeologies and high variation in heterochromatin distribution between Citrus L. and Poncirus Raf. as evidenced by comparative cytogenetic mapping
TLDR
A comparative cytogenetic map for Citrus medica and Poncirus trifoliata showed a high degree of sequence conservation between these genera, enabling heterologous hybridization of BACs, and the establishment of chromosomal homeologies.
Chromosome homologies between Citrus and Poncirus—the comparative cytogenetic map of mandarin (Citrus reticulata)
TLDR
A break of colinearity was observed between BAC clones and the CMA+ bands (including rDNA loci) from chromosomes 2 and 3, which could be mainly explained by amplification and reduction of the satellite DNA sequences that constitute the heterochromatic bands of these chromosome pairs.
A simple chromosomal marker can reliably distinguishes Poncirus from Citrus species
Several chromosome types have been recognized in Citrus and related genera by chromomycin A3 (CMA) banding patterns and fluorescent in situ hybridization (FISH). They can be used to characterize…
Chromosomal markers distinguish hybrids and non-hybrid accessions of mandarin
TLDR
A chromosome marker for mandarin species was identified and the relationship among the pure species and some hybrids is discussed, which suggests mandarins can be separated karyologically into three groups.
Cytogenetic Map of Pummelo and Chromosome Evolution of True Citrus Species and the Hybrid Sweet Orange
TLDR
The aims of this study were to investigate the karyotypic changes involved in the chromosomal evolution between true citrus and to shed light into the origin of sweet orange hybrid karyotype, and to identify chromosome homoeologies between pummelo and other true citrus species.
Karyotype diversity of Korean landrace mandarins by CMA banding pattern and rDNA loci
Karyotype differentiation among Spondias species and the putative hybrid Umbu-cajá (Anacardiaceae)
TLDR
From the chromosome banding and the distribution of rDNA sites, as well as from the genomic in situ hybridization, it seems clear that Umbu-caja is related closely to S.monbim and S.tuberosa, but it is karyotypically homozygous and distinct from theses other species.
Comparative Analyses in Lotus: The Cytogenetic Map of Lotus uliginosus Schkuhr
A comparative cytogenetic map was built for Lotusuliginosus (2n = 12), expanding previous analyses that revealed intra- and interspecific chromosomal rearrangements in the model legume L. japonicus,…

Chromosomal relationships among cultivars of Citrus reticulata Blanco, its hybrids and related species
TLDR
Those of group I and the Mediterranean mandarins (group II) are the best candidates to represent C. reticulata (sensu Swingle) as a true species.
A Numerical Taxonomic Study of Affinity Relationships in Cultivated Citrus and Its Close Relatives
TLDR
The affinity relationships of 43 biotypes of cultivated Citrus-close relatives, interspecific and intergeneric hybrids, and clones of unknown origin-were studied to develop information for use in citrus breeding experiments to support the proposed systematic relationships.
Citrus phylogeny and genetic origin of important species as investigated by molecular markers
TLDR
Phylogenetic analysis with 262 RAPDs and 14 SCARs indicated that Fortunella is phylogenetically close to Citrus while the other three related genera are distant from Citrus and from each other.
Genetic diversity in the orange subfamily Aurantioideae. I. Intraspecies and intragenus genetic variability
TLDR
M measuring genetic variability and studying its pattern of distribution are crucial steps to optimize sampling strategies in the search of genotypes that tolerate or resist these threatening factors within the huge array of Citrus and Citrus related species.
Studies on the origin of the lemon
TLDR
The presence of much sterility and wide segregation of characters argues against the specific standing of C. limon, which has a common gene source with the citron-lime group, and it may be a derived hybrid involving some unidentified taxa.
Phylogenetic relationships within the genus Citrus (Rutaceae) and related genera as revealed by RFLP and RAPD analysis
TLDR
Relationships among 88 accessions representing 45 Citrus species, three man-made hybrids, and six related genera were examined for restriction fragment length polymorphisms (RFLP) and random amplified polymorphic DNA (RAPD) analysis showed that several accessions were probably assigned to the wrong species.
Cytogenetics of Rutaceae. V. High chromosomal variability in Citrus species revealed by CMA/DAPI staining
TLDR
The CMA staining revealed some chromosome markers for each Citrus species that may be very useful in the identification of zygotic versus nucellar embryos, as well as for further evolutionary studies.
Cytological heterozygosity and the hybrid origin of sweet orange [Citrus sinensis (L.) Osbeck]
TLDR
Citrus sinensis chromosomes, although small in size, present a remarkable differentiation of bands with the fluorochromes CMA and DAPI suggesting that some heteromorphisms are fixed in this species.
Chromosome number and secondary constriction variation in 51 accessions of a citrus germplasm bank
TLDR
The mitotic chromosomes of 51 citrus accessions from the Centro Nacional de Pesquisa em Mandioca e Fruticultura Tropical, Cruz das Almas, BA, Brazil, were analyzed and showed high variability in the number and position of secondary constrictions, indicating a high structural variability and heterozygosity of citrus germplasms.
Isozyme analysis and phylogenic relationship of citrus
TLDR
From the analysis, Natsumikan (Citrus natsudaidai), Hassaku, Hassaku and some other citrus cultivars are considered to be hybrids of pummelo (C.grandis) and mandarin as suggested, and Iyo, which has been assumed to be a hybrid of sweet orange andMandarin, was found to have a genetic effect from pummela.
