to be very useful and successful in cloning genes in sunflower. Intensive
studies have also been performed to understand promoter structure of genes
in sunflower and to analyze the transcription pattern in different tissues
and under different environmental conditions. Functional analyses to
characterize or verify candidate genes by transgenic approaches have been
performed in sunflower or even more successful in heterologous systems
e.g., tobacco and Arabidopsis .
The feasibility of association mapping offers new possibilities to identify
genes responsible for a phenotype. In addition, the identification of genes
underlying major QTLs for agronomically important traits will present a
challenge for sunflower researchers in the coming years. For the future,
there is still a lot of work to be done to clone and characterize genes, especially
those specific for sunflower.
