RAPD Analysis of Aromatic and Non-aromatic Rice (Oryza sativa L.)
摘要:
Genetic variation in nine aromatic and four nonaromatic rice varieties (Oryza sativa L.) was investigated at the DNA level using the randomly amplified polymorphic DNA (RAPD) technique. Twenty six random primers were used to amplify DNA segments and 177 PCR products were obtained of which 98 were polymorphic. One primer did not show polymorphism. A dendrogram showing the genetic distances of 13 rice varieties was constructed based on RAPD data.

Organozinc halides, which are prepared either by direct zinc insertion or halogen magnesium exchange and subsequent transmetalation with ZnCl2, react smoothly with commercially available trichloroacetyl isocyanate to give, after hydrolysis, the corresponding primary amides. This method is compatible with a variety of functional groups such as an ester or a cyano group. Also heterocyclic-, alkenyl, and acetylenic zinc reagents are converted to the corresponding primary amides under these conditions.
