While Arabidopsis bears only one MET1 gene encoding the DNA methyltransferase that is mainly responsible for maintaining CG methylation after DNA replication, rice carries two MET1 genes, MET1a and MET1b, expressed in actively replicating and divi...

PolA1, a single-copy nuclear gene encoding the largest subunit of RNA polymerase I, comprises highly polymorphic intron 19 and nucleotide tag (Ntag) sequences. We analyzed these sequences in 42 accessions, which differed in ploidy, of Triticum-Aeg...

To develop a rice cultivar that would be suitable for direct-seeding cultivation in cooler temperate regions, we generated transgenic rice plants in which a rice encoding a ζ-class glutathione S-transferase (GST) under the control of a maize ubiqu...
