Characterisation of the double genome structure of modern sugarcane cultivars (Saccharum spp.) by molecular cytogenetics
TLDR
Using comparative genomic DNA in situ hybridization, it is demonstrated that it is possible to distinguish the chromosomes contributed by these two species in an interspecific F1 hybrid and a cultivated clone, R570, and for the first time the occurrence of recombination between the chromosomes of these twospecies.
Genetic dissection of a modern sugarcane cultivar (Saccharum spp.). I. Genome mapping with AFLP markers
TLDR
An AFLP genetic map based on a selfing population of a specific cultivar, R570, is constructed and the genome coverage was significantly increased, illustrating the difficulty to access large portions of chromosomes, particularly those inherited from S. spontaneum.
RFLP mapping in cultivated sugarcane (Saccharum spp.): genome organization in a highly polyploid and aneuploid interspecific hybrid.
TLDR
A mapping study on the progeny of a selfed cultivar, R570, suggested the prevalence of random pairing between chromosomes, typical of autopolyploids, however, cases of preferential pairing between S. spontaneum chromosomes were also detected.
A high-density linkage map of Theobroma cacao L.
TLDR
A mapping population of 181 progenies resulting from a cross between two heterozygous genotypes, a Forastero and a Trinitario, was used for the linkage analysis and a new DNA isolation protocol was established, which allows enough good quality DNA to construct a genetic map with PCR-based markers.
Genetic dissection of a modern sugarcane cultivar (Saccharum spp.).II. Detection of QTLs for yield components
TLDR
An extensive Quantitative Trait Allele (QTA) mapping study based on a population of 295 progenies derived from the selfing of cultivar R570 shows the presence in the genome of numerous QTAs, with little effects, fluctuating slightly across cycles, on the verge of being perceptible given the experimental resolution.
Analysis and functional annotation of an expressed sequence tag collection for tropical crop sugarcane.
TLDR
A global analysis of the whole SUCEST data set indicated that 14,409 assembled sequences contained at least one cDNA clone with a full-length insert, which indicated that possibly 33,620 unique genes had been identified and indicated that >90% of the sugarcane expressed genes were tagged.
A saturated genetic linkage map of rubber tree (Hevea spp.) based on RFLP, AFLP, microsatellite, and isozyme markers
TLDR
The disomic inheritance observed for all the codominant markers scattered on the 2n=36 chromosomes revealed that Hevea behaves as diploids, and comparison of the distance between loci in the parental maps revealed significantly less meiotic recombination in the interspecific hybrid male parent than in the female parent.
Orthologous comparison in a gene-rich region among grasses reveals stability in the sugarcane polyploid genome.
TLDR
This analysis of sugarcane haplotype organization at the sequence level suggests that the high ploidy in Sugarcane did not induce generalized reshaping of its genome, thus challenging the idea that polyploidy quickly induces generalized rearrangement of genomes.
Genetic diversity in coconut (Cocos nucifera L.) revealed by restriction fragment length polymorphism (RFLP) markers
TLDR
A study of the genetic diversity in coconut by RFLP analysis was performed in 100 individuals representing 10 Tall and seven Dwarf local populations or 'ecotypes' from various geographical origins and the legitimacy of two hybrids between ecotypes was confirmed and maternal inheritance of mitochondrial genome was observed.
