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

Abstract

   The sustainability and increasing the national rice production require the readiness of food and agriculture sector cope with the impacts of climate change, land degradation, drought area, sloping production and the raising of population growth. Adaptation plays an important role in ensuring the sustainability of food security. This research aimed to develop drought-tolerant variety of Inpari 30 (submergence tolerance variety) and Situ Bagendit through marker-assisted backcrossing-through pyramiding gene of identified QTLs for foreground selection and to explore SSRs and 6K SNPs for background selection distributed in 12 rice chromosome of drought tolerant donor (Cabacu) and recipient rice (Inpari 30 and Situ Bagendit). The foreground selection revealed that flanking SSRs of each QTLs (qRPF2.1, qGPP2.1, qSPP4.1 and Sub1) was less than 2 cM. The background selection through polymorphic survey of Rice 6K SNP primers revealed 2457 (53,3%) polymorphic SNPs on Inpari 30 vs Cabacu and 2563 (55,6%) polymorphic SNPs on Situ Bagendit vs Cabacu with the average distance about 0.74 cM/chromosome. The genotypic selection of F1 Inpari 30/Cabacu and F1 Situ Bagendit/Cabacu have already in heterozygote condition for these 4 QTLs target. These lines was continued for backcross breeding to develop BC1F1 Inpari 30/Cabacu and BC1F1 Situ Bagendit/Cabacu generation.
