(1)physical mapping of the important function and economic character
genes inrice,maize and barley using in situ hybridization.
(2)Comparative physical mapping among rice ,maize and barley using in
(3)Characterization of alien introgression in wide-cross derivatives
and transgenic plants of rice, maize and barley
(4)Analysis of arrangment and organization of genes in the single
chromosome, for example, chromosome No.4 in rice.
(5)The programed cell death in plants
Up to now,the molecular genetic maps have been developed in some cereal
crops including rice,maize and barley etc.However,the genetic map can only
show the relative position and distance between the makers on the
chromosome.In order to know the real position,distance and relationship
between the markers on the chromosome,physically mapping them is
In situ hybridization(ISH)is a powerful tool for physical mapping of
genes.We have improved the ISH technique and mapped many RFLP and cDNA
markers in rice and maize.The results showed that the genetic and physical
maps are different from eath other.Two markers that covered a short
genetic distance might be physically distant,and vice versa.The RFLP
markers were not distributed all along the whole length of the
chromosome,for example,the markers of linkage group 11 distributed only in
the short arm of chromosome 11 in rice.Although the exact reason for the
differences between the genetic and physical maps is still
unknown,according to the comparisons between this two kinds of maps we
could obtain much deeper insight about the structure of the genome. Our
follow-up work is to physically map the important function and economic
character genes including those dictating the resistances to
disease,insect,and tolerance to low temperature,drought stress and soil
which contains rather high concentration of salt,alkaline,and acid,etc.in
rice,maize and barley.Now we are developing the sequential fluorescent in
situ hybridization(FISH)and chromosome G- banding technique,and have
already obtained some success.In the next step,we will adopt the technique
and use cDNA or molecular markers closely linked with these genes as probe
to locate this genes onto the special band regions of a given chromosome.
The objective is to construct a cytological map including the important
genes in the cereal crops.This map will offer very important information
for developing the rice biotechnology and understanding the organizations
and functions of the genomes in rice ,maize and barley.This also will
closely connect the cereal crop research on the molecular level with that
on the cytological level and promote the development of plant molecular
cytogenetics. There are many homologous segments of chromosomes among
rice,maize and barley.To compare their physical maps is an effective way
for analysis of their homogeneities.The knowledge about the homogeneities
will help us to recognize the relationship of classification and evolution
among these crops.
It is still unknown how to organize different kinds of genes oneach
chromosome.To study it deeply will increase the insight about fine
structure of chromosomes. Developmental biology is a precursory field
in life science.It is evident that the mechanisms of development could be
revealed by studing the time and space changes of genome structure and
