@article{Carvalho2005TheRA, title={The relationships among lemons, limes and citron: a chromosomal comparison}, author={Reginaldo de Carvalho and Walter dos Santos Soares Filho and Ana Christina Brasileiro-Vidal and Marcelo Guerra}, journal={Cytogenetic and Genome Research}, year={2005}, volume={109}, pages={276 - 282} }
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…

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
- BiologyChromosome Research
- 2010
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

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)

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.

Chromosomal markers distinguish hybrids and non-hybrid accessions of mandarin

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.

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.

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.

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.
