Abstract
At the post-genomics era, studies
on the mutants play a central role to
understand the function of each genes.
This includes inducing mutants, study
on mutated traits, pull out target gene
through forward or reverse genetics,
and perform the analysis for that
specific gene. The rice genome
sequencing draft was released recently
by the international consortium and
two private sectors. Here in Taiwan,
several groups have been generating
rice mutants through T-DNA tagging,
Ac/Ds tagging and sodium azide
treatment recently. From those
populations, we are able to screen
several mutants on grain composition.
They would be used as the material for
the present project.
In the next three years, we will
emphasize on the following three
mutant characteristics: waxy (and
so-called semi-waxy) rice, colored rice,
and fragrant rice. We will also cross these mutants with indica rice for the
generation of F2 segregating population.
They will then be used for the material
of genetic analysis and positional
cloning.
In the first year, we have obtained
several color endosperm mutants from
T-DNA tagging sodium azide-induced
mutated populations. And we also have
many ancient rice samples supported
by archaeologists of Academia Sinica,
which would be used in comparative
investigation with our mutants.
