In this article we will discuss about the current status and collaborative work on rice genomics. Rice (Oryza sativa) is a model species for monocotyledonous plants, particularly for members in the grass family. With the completion of the Arabidopsis genome, plant biologist will have greater opportunity to assess the entire gene sequence of a plant for the first time and [...]
Natural occurrence of antisense RNA and its role in gene regulation have been realised long ago. Gene expression in both prokaryotes and eukaryotes are controlled by the product of regulatory gene, which are supposed to be proteins only. Recently, naturally occurring regulatory gene that directs the synthesis of RNA which can control gene expression. This newly discovered RNA repressor can [...]
Realising the role of antisense RNA technology in the reduction of ethylene production, a cDNA (pTOM13) encoding ACC oxidase has been isolated from a tomato fruit ripening library. An antisense gene construct from the cDNA strongly inhibited expression of ACC oxidase activÂity in transgenic tomatoes. A chimaeric pTOM13 antisense gene, encodes ACC oxidase consistÂing of 1.3 kilobase (kb) fragment of [...]
