Sequence analysis of OsMAX1 genes in rice
Using the tool of homologous sequence alignment in
NCBI, we predicted the AtMAX1 homologous genes in
rice genome database (http://rice.plantbiology.msu.edu/
index.shtml) and identified five OsMAX1 candidate
genes with high homology to AtMAX1, OsMAX1a
(LOC_Os01g50530 and LOC_Os01g50520, and cDNA
sequencing showed that these two annotated loci are
in the same ORF), OsMAX1b (LOC_Os06g36920),
OsMAX1c (LOC_Os01g50590), OsMAX1d (LOC_
Os01g50580) and OsMAX1e (LOC_Os02g12890)
(Table 1). These candidate genes shared 50%–63%
sequence homology with AtMAX1.
These five candidate genes were searched in Gramene
(http://www.gramene.org/Multi/blastview) to determine
their chromosomal distributions. Using genome sequence
and cDNA sequence, we analyzed the structural
characteristics of their introns and exons (Fig. 1). The
results showed that these OsMAX1 candidate genes
