Abstract This project aims to deliver information on the coordinate control of growth and development in perennial grasses through the association of flowering time and senescence QTL, with flowering time genes in the C4 energy grass Miscanthus. It is proposed to investigate the molecular basis of flowering in this species by identifying homologues of flowering time genes already identified in the model plants Arabidopsis, rice and maize. There are over 40 flowering time associated genes mapped in riceand approximately half of these have also been mapped in maize. We therefore propose to exploit the dense SSR genetic maps of maize to build genetic maps of Miscanthus regions, focused around these candidate genes, supplementing the maize markers with a smaller number of sugarcane SSRs. Replicate mature plants of two mapping families used to genetically map the candidate flowering time regions will be phenotyped for heading date. This will therefore test the hypotheses that (1) Arabidopsis, riceand maize can be used as genetic models for the control of flowering time in Miscanthus, and (2) Miscanthus cDNAs homologous to rice and Arabidopsis flowering genes can be mapped to Miscanthus flowering time QTL. Mapping homologues of flowering time genes in Miscanthus will also provide comparative genetic information on the extent of synteny that exists between Miscanthus and other grasses. To further test candidate genes from model organisms which co-map to flowering time QTL in Miscanthus,shifts in allele frequency of the Miscanthus orthologous within synthetic populations selected for early and late flowering time will be monitored using SNPs. In other words to test if differences in flowering response exhibited by different Miscanthus species and genotypes are a consequence of allelic variation in orthologues of Arabidopsis and other model species flowering time control genes.
