1. Goals
(1) To develop a technology to isolate rice genes and use such genes; and
then isolate the genes that control agriculturally important traits, such
as resistance to disease, insect pest attack, and low temperatures
(2) To develop a technology for
efficient functional analysis of rice genes and identify the biological
functions of expressive genes (cDNA)
2. Research plans
1) Isolation of useful genes through a molecular biological technique
(1) Purpose of research
To develop an efficient gene separation technology by using genetic maps
obtained in the first phase of the Rice Genome research project and to
isolate the genes that control agriculturally important traits
(2) Research plans
To develop an efficient gene isolation
method using DNA markers and well-ordered DNA fractions (map-based cloning) and
a gene isolation method using transposons (transposon tagging) and isolate the
genes that control agriculturally important traits
(3) Goals
To develop an efficient method to isolate the genes that control agriculturally
important traits such as resistance to disease, insect pest attack, and
low temperatures
To contribute to the cultivation of
breakthrough varieties with new traits such as disease and insect pest
resistance by transducing isolated genes into rice
2) Identification of biological functions of genes
(1) Purpose of research
To develop technologies to analyze
the biological functions of expressive genes (cDNA) and regulate their
expressivity
To develop a related applications
technology
(2) Research plans
To develop a technology to
efficiently screen genes broken off from variants produced from transposons,
identify their biological functions, and isolate useful genes by utilizing a
gene disruption system
(3) Goals
To develop a technology to efficiently analyze the biological functions
of genes that have important functions in agriculture such as seed maturation
and growth of somatic material and contribute to the cultivation
of landmark breeds with new traits by transducing such genes into rice.
