The authors reveal and compare the changing patterns of gender segregation in the composition of students who have graduated from universities in Japan, Korea, and Taiwan since 2004. The students are classified into 7 categories in accordance with the ISCED97: Education, Humanities & Arts, Social Sciences, Science & Mathematics, Engineering, Agriculture & Veterinary, and Health & Welfare. We discuss (1) the situation of female PhD graduates and (2) the ratios of men and women at the various levels of higher education (bachelor, master, PhD) in each field.

The <i>waxy</i> (<i>wx</i>) gene of <i>Oryza glaberrima</i> was cloned, and its nucleotide sequence was determined. A waxy mutant of <i>O. glaberrima</i> showing a glutinous phenotype was found to contain a substitution mutation generating a termination codon in the coding region of the <i>wx</i> gene. The <i>Wx</i> sequence of <i>O. glaberrima</i> was different from that of <i>Oryza sativa</i> by substitutions and insertions/deletions, among which only a few substitutions occurred in several exons not to severely alter the amino acid sequence of the <i>Wx</i> protein. The most striking difference observed in introns was a 139-bp deletion (or insertion) in intron 10 of <i>O. glaberrima</i> (or <i>O. sativa</i>). In <i>O. sativa</i>, 125bp of the 139-bp sequence was flanked by direct repeats of a 14-bp sequence. A sequence homologous to the 125-bp sequence was found in the region preceding exon 2; this sequence was also flanked by direct repeats of another 14-bp sequence. This result and the observation that the 125-bp sequence was interspersed in rice genomes indicate that they are SINEs (short interspersed elements) in the plant system. We also identified a DNA sequence with long terminal inverted repeats in intron 13 of both <i>O. glaberrima</i> and <i>O. sativa</i>. This sequence was present in multiple copies in rice genomes, suggesting that it is a transposable element. These results obtained suggest that mobile DNA elements have diversified the rice <i>Waxy</i> gene by inserting into introns, each of which may originally have a length of about 100 bp.<br>
