Description

Since 1991, Oji Paper has been advancing the overseas forest plantation business for securing the forest resource and to protect the environment. Paper quality is greatly affected by the fiber properties such as fiber length, cell wall thickness, cellulose and lignin content. To get comprehensive understanding the fiber development, we have developed the EST database and oligo-microarray system for the Eucalyptus genomics.<BR>We already collected the gene expression profiles of three different Eucalyptus trees using our Eucalyptus oligo-microarray. To identify the expression trends of the genes involved in cellulose and lignin biosynthesis, we performed the trending data analysis using their expression profiles among several samples. Their trends could be divided into two groups, clearly. Finally, we identified the two gene clusters. Each cluster has several transcription factors (TFs) . We already reported that EcHB1 (HD-Zip class II) and EcMYB1 (Werewolf-like MYB) can be used to improve growth and fiber properties by analyzing transgenic tobacco plants as model experiments in 2007 IUFRO Tree Biotechnology meeting at.<BR>Currently, with the modified EcHB 1 gene, we succeeded with creating “Super-Eucalyptus”. In this report, author show details of the latest results in own study.
