Establishment of the genomic in situ hybridization (GISH) technique for analysis in interspecific hybrids of Passiflora.
The genomic in situ hybridization (GISH) technique was applied to Passiflora interspecific F1 HD13-133 hybrids (Passiflora sublanceolata x Passiflora foetida) and HD15-101 (Passiflora gardineri x Passiflora gibertii), and the backcrossed hybrids (BC1) HD18-106 and HD18-113 (Passiflora sublanceolata x HD13-133). GISH was performed using genomic probes prepared with the DNA from the paternal geni...
متن کاملCytological characterization of an interspecific hybrid in Jatropha and its progeny reveals preferential uniparental chromosome transmission and interspecific translocation
Genetic variation in Jatropha curcas, a prospective biodiesel plant, is limited, and interspecific hybridization needed for its genetic improvement. Progeny from interspecific crosses between J. curcas and Jatropha integerrima can be used to improve agronomic characters and to increase oil content and yield. However, these hybrids have not been characterized cytologically. The present study was...
متن کاملthe study of chromosome constitution in secondary tritipyrum genotypes (f2) by genomic in situ hybridization technique (gish)
to remove unfavorable traits of new cereal tritipyrum (2n=6x=42, aabbebeb), various crosses between primary tritipyrum lines (female) with iranian bread wheat varieties (2n=6x=42, aabbdd) was performed and a f2 selfing population consisted of 1810 possible secondary tritipyrum seeds (2n=6x=42, aabbd(0-14) eb(0-14)) were produced. the chromosome constitution and homology index of 11 plants of th...
متن کاملCytological Characterization and Pollen Viability Studies in the Interspecific Hybrids between Helianthus Annuus and Helianthus Maximiliani
The present investigation was undertaken with a view to study Cytological behavior of F1 interspecific hybrids of diploid wild perennial species Helianthus maximilini (2n = 34) and with cultivated sunflower Helianthus annuus (2n = 34) prebred line M-106. The interspecific hybrids have annual life cycle with the diploid somatic chromosome number thirty four. Chromosome association represented by...
متن کاملIdentifying parental chromosomes and genomic rearrangements in animal hybrid complexes of species with small genome size using Genomic In Situ Hybridization (GISH)
Genomic In Situ Hybridization (GISH) is a powerful tool to identify and to quantify genomic constituents in allopolyploids, and is mainly based on hybridization of highly and moderate repetitive sequences. In animals, as opposed to plants, GISH has not been widely used in part because there are technical problems in obtaining informative results. Using the allopolyploid Squalius alburnoides Ste...
