Prenatal Diagnosis, Sampling of Chorionic Villi
Prenatal diagnosis with application of the Amniotic fluid (Amniocentesis: AC) and chorionic villi sampling {CVS) is a general aspect of application in Human Genetics which facilitate the diagnosis of different Genetic defects, enclosing chromosomal abnormalities and Genosomopathies. Diagnosis of Genetic defects for AC and CVS is between 16-20th and 8-12th weeks of gestation respectively. Allica...
متن کاملSomaclonal Variation in Tissue Culture: A Case Study with Olive
Micropropagation of woody plants and fruit crops constitutes a major success in the commercial application of in vitro cultures. An important aspect to be considered when deriving perennial plants from micropropagation is the maintenance of genetic integrity with regard to the mother plant. In this regard, somaclonal variation has been reported at different levels (morphological, cytological, c...
متن کاملDetection of somaclonal variation in plants regenerated from different tissues of strawberry (Fragaria x ananassa) using ISSR marker
Production of genetically and phenotypically stable plantlets is the main purpose in commercial strawberry tissue culture. In this study, different tissues of Fragaria ananassa cv. Camarosa including stipule, apical meristem, leaf and petiole were cultured in Murashige and Skoog (MS) medium supplemented withdifferent concentrations of N6-benzyladenine (BA) (0.5, 1, ...
متن کاملA SIMPLIFIED AND EFFECTIVE PROTOCOL FOR PRODUCTION OF BREAD WHEAT HAPLOIDS (n = 3x = 21, ABD) WITH SOME APPLICATION AREAS IN WHEAT IMPROVEMENT
Somaclonal variation, aneuploidy, and genotypic specificity are major limitations of anther culture and bread wheat x Hordeum bulbosum crosses for producing haploids (n=3x=21, ABD). Sexual combinations of wheat x Zea mays have since emerged as an alternate and significant procedure as wheat genotypic specificity does not exist. This procedure has been refined and simplified over the last decade...
متن کاملFISH and GISH: Modern cytogenetic techniques
In recent years, advances in the molecular cytogenetic technique of fluorescence in situ hybridization (FISH), which enables the direct chromosomal localization of labelled DNA probes and genomic in situ hybridization (GISH), which determines the inter-species distribution of repeated sequences have enabled a resurgence of cytogenetic analysis in plant genome research and molecular breeding. Pr...
