Thesis title: Genome wide association study for identification of genes involved in ion accumulation in rice grain.

A study was conducted to investigate and identify the candidate genes in relation to cadmium and zinc transportation and accumulation in rice. Using 281 diverse rice accessions and employing genome wide association analysis to relate 46294 single nucleotide polymorphic panel and cadmium and zinc ionomic data, mixed linear model was adopted to establish the association, if any, between genotypic and ionomic data. Statistical tools used and computational applications adopted during the analyses include Discriminant Analysis of Principal Components (DAPC), Principal Coordinate Analysis (PCoA), Neighbour Joining Tree, Structure, Haploview and R-tool. Differential accumulation of cadmium and zinc in different vegetative tissues of two diverse rice accessions was also investigated under cadmium induced stress condition. Finally, expression profiles of OsHMA2, OsHMA3 and OsPCSs genes under cadmium induced stress condition were examined.
