Abstract

Rice stem borer (Scirpophaga sp.) is considered as one of the primary pests causing yield decrease in Indonesia. Genetic engineering is considered as one of the most effective way to improve the resistance of rice plants to yellow stem borer since no resistance gene has been found in rice and its wild relatives. A double T-DNA binary vector p2TDNAcryIAb wich carry two independent T-DNA was used to transform Indonesian elite rice cv Ciherang using Agrobacterium-mediated transformation to generate transgenic rice that free from selectable marker genes. One T-DNA containing a selectable marker hygromycin phosphotransferase (hpt) gene and the other carrying the cry1Ab gene. As many as 37 putative transgenic plants from 14 embryos were generated. PCR analysis demonstrated that 22 out of 37 putative transgenic rice contain cry1Ab gene. All Ciherang rice carrying the cry1Ab gene expressing Cry1Ab protein as shown by the immunostrip assay. Further work will be carried out to determine the transgenes copy number, to select marker free transgenic rice, and to evaluate the resistance of transgenic rice against neonates larvae of yellow stem borer.Keyword: double T-DNA, transgenic rice, Cry1Ab, transformation

Abstract

The studies of rice genes through functional genomics are greatly facilitated by the availability of the complete genome sequences, including the complete physical map of the japonica rice cv. nipponbare. Using the Ac and Ds transposon, that are capable of transposition in various heterologous plants including the monocotyledon rice,  combined with the enhancer element for generating activation taged lines, it is possible to discover and isolate functional genes involved in various important agronomical traits; such as those involved in abiotic stress tolerance (drought, high salt) and biotic stresses diseases and pests. We have developed 1,785 first (T0) generation of mutant nipponbare rice by transposons Ac/Ds insertions containing activation-tag, generated by transformation using Agrobacterium-mediated method. Currently, we have generated approximately 1,000 stable lines with transposon Ds and activation-tag insertion ready for screening. Efficient screening methods for mutant Nipponbare rice lines have been established for agronomically important mutant traits. Among the new phenotypes related to important agronomical traits observed were drought and salt tolerant or sensitive, stunted and robust growth, variable root penetration and other interesting traits such as reduced tillering, rolled leaf and thin tiller.   Keywords: rice, insertion mutant, gene discovery, drought, salinity
