Outline of Final Research Achievements |
Previously, we revealed that auxin and wound-inducible hormones contributed to the control of tissue reunion process in upper and lower part of incised stem by inducing the expression of plant-specific TFs, ANAC071 and RAP2.6L, respectively. In this study, analysis of tissue-specific gene expression and hormone biosynthesis during tissue-reunion process in incised Arabidopsis flowering stem were perfomed. Gene expression analyses show that expression of those TFs were up-regulated within 3 h after incision. We also found that some JA-related mutants showed incomplete healing process in tissue reunion, and arf6arf8 mutant showed inhibition of cell division in pith tissue after a week of incision.
