R
ice (
Oryza sativa
L.) is a principle crop in Vietnam and plays an important role in economic activity in this country. However, rice
growing areas and rice productivity are significantly reduced due to increasing adverse impacts from climate changes as emerging
pathogens, drought and rising sea levels. Our attempts have made collaboration with The Genome Analysis Center-TGAC (Earlham
Institute), the John Innes Centre (JIC) in UK to launch the collaborative projects which focused on re-sequencing some Vietnamese
rice landraces. Some successful works have been made in investigation, data collection, building of native rice landraces of Vietnam
(focus on good quality rice varieties with tolerance to biotic and biotic stresses); analyzing genetic diversity of native varieties in
Vietnam at the molecular level, selected 36 elite rice varieties with high diversity for genome sequencing; coordinating full genome
sequencing, building genotype databases; adding supplementary assessments of major morphological agronomy traits, establishing
phenotype databases of the genome sequenced rice landraces; mapping SNPs; design to CAPS markers for research and breeding;
launching the project website to manage and sharing genotype and phenotype database of rice; training researchers and staff in
the field of genome sequence and genome-data mining of rice; published some research articles on the National and International
Journals. In the second phase of collaboration, we have re-sequenced the genomes of more 600 Vietnamese native rice varieties and
exploited their databases by applying bioinformatics pipelines to identify association of alleles with specific agronomic phenotypes
traits of interest. The rapid identification of rice landraces those are tolerant and resilient to adverse conditions which will work
towards alleviating the current challenges the country agriculture industry face and contribute to food security. Currently, a number
of promising rice lines carrying specific/multiple genes, candidate genes of abiotic and biotic tolerances from rice genome sequence
(salt tolerance, bacterial leaf blight, and plant brown hopper resistances) have been developed by molecular breeding programs and
were sent for National Test and will be released to the farmers soon time.
