Gene flow from cultivated rice (Oryza sativa) to its weedy and wild relatives.
BACKGROUND AND AIMS Transgene escape through gene flow from genetically modified (GM) crops to their wild relative species may potentially cause environmental biosafety problems. The aim of this study was to assess the extent of gene flow between cultivated rice and two of its close relatives under field conditions. METHODS Experiments were conducted at two sites in Korea and China to determi...
متن کاملGenetic Diversity in Sadajira Rice (Oryza sativa L.) Germplasm
Genetic diversity of 40 traditional Bangladeshi rice genotypes was studied under rainfed condition through Mahalanobis D statistic for grain yield and yield contributing characters. The genotypes were grouped into six clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the genotypes of different clusters. The intra-cluster dist...
متن کاملGenetic polymorphism in rice (Oryza sativa L.) through RAPD analysis
Random Amplified Polymorphic DNA (RAPD) assay was performed to estimate genetic polymorphism in six different rice (Oryza sativa L.) cultivars viz. Basmati 370, DM 25, IRATOM 24, Binadhan 6, TNDB 100 and Y 1281. Three out of the 15 decamer random primers showed amplification of genomic DNA in 24 individuals. The primers produced a total of 26 bands of which 14 were polymorphic. Proportion of po...
متن کاملGENETIC DIVERSITY ANALYSIS IN RICE (Oryza sativa L
The experiment was conducted under the agro-ecological zone of Modhupur Tract (AEZ-28) to determine the genetic diversity among 39 rice genotypes, collected from Bangladesh Rice Research Institute, Lal Teer Seed Ltd. and Chittagong Hill Tracts. The genotypes were grouped into six clusters based on Mahalanobis’s D 2 statistics and Canonical Variate Analysis. Cluster I consisted with the highest ...
متن کاملMultilocus analysis of nucleotide variation of Oryza sativa and its wild relatives: severe bottleneck during domestication of rice.
Varying degrees of reduction of genetic diversity in crops relative to their wild progenitors occurred during the process of domestication. Such information, however, has not been available for the Asian cultivated rice (Oryza sativa) despite its importance as a staple food and a model organism. To reveal levels and patterns of nucleotide diversity and to elucidate the genetic relationship and ...
