Abstract: In order
to investigate expression changes of genes related to chromosome remodeling
induced by implantation with low-energy N+ beam in rice, the
differentially expressed genes related to chromosome
remodeling in treated samples (6×1017 N+/cm2),
were screened using Agilent gene chip. The results
showed that, in the treated samples, 1 out of
30 genes related to histone deacetylase was up-regulated. Expressions of 48 genes related to
histone acetyltransferases (HATs), two SNF2-related domain containing proteins and one SWIM Zn-finger domain containing
protein were up-regulated, one SWIB/MDM2 domain containing protein and one
TAFII55 protein conserved region domain containing protein were down-regulated,
expression of 3 GCN5-related N-acetyltransferase domain containing proteins
were significantly different, in which one was
up-regulated and two down-regulated. There are several conserved protein domains
related to chromosome remodeling on the Microarray, Expressions of 2 of 38
bromodomainrelated genes were changed of which
one is up-regulated and the other down-regulated. Expressions of 2 of 7
chromodomain related genes and 8 of 36 SET related genes were up-regulated.
Besides, one expression of 14 LSD1 type domain containing protein was
significantly up-regulated. These findings suggest that the expression changes
of genes related to chromosome remodeling may regulate the expression of
certain genes responding to ion implantation, and induce the biological effect
of the rice implanted by ion beam.
