Abstract i Table of contents iii List of Figures and Tables v Abbreviations viii Chapter I General Introduction - 1 - 1.1 Overview of plant senescence - 1 - 1.2 Regulation of senescence - 2 - 1.3 Senescence of organs - 3 - 1.3.1 Root senescence - 4 - 1.4 Objectives - 10 - Chapter II. Characterization of changes in molecular, cellular, and physiological characteristics in primary RAM along age - 11 - 2.1 Introduction - 11 - 2.2 Materials and Methods - 15 - 2.3 Results - 19 - 2.3.1 The rates of cell division and auxin and cytokinin responses in the primary RAM change as the root ages - 19 - 2.3.2 Size of QC cells and expression of QC cell-specific marker genes in the primary RAM are temporally changed - 21 - 2.3.3 Genotoxic stress tolerance of QC cells decreases with root age - 25 - 2.3.4 QC cells protect theMasterelves from genotoxic stress via mechanisMaster other than asymmetric chromosomal segregation (ACS) - 27 - 2.3.5 The rate of QC cell division is temporally regulated - 32 - 2.4 Discussion and conclusion - 37 - Chapter III. ORESARA 15 (ORE15) is a temporal regulator of maintenance of primary RAM along age - 41 - 3.1 Introduction - 41 - 3.2 Materials and methods - 44 - 3.3 Results - 52 - 3.3.1 ORE15 shows temporal decrease in expression level in primary RAM - 52 - 3.3.2 ORE15 regulates the size of RAM - 54 - 3.3.3 ORE15 regulates the dynamics of meristem size along age - 56 - 3.3.4 ORE15 regulates the dynamics of root growth rate along age - 58 - 3.3.5 ORE15 controls the cell size in RAM and other zones in root - 62 - 3.3.6 ORE15 regulate cell division in proximal RAM and stem-cell niche - 64 - 3.3.7 ORE15 is a temporal regulator of cell division dynamics in RAM - 71 - 3.3.8 ORE15 is invloved in the auxin hormonal regulation of RAM - 76 - 3.3.9 ORE15 modulates the process of auxin transportation in RAM - 81 - 3.3.10 ORE15 and auxin positively feedback each other - 85 - 3.3.11 Downstream targets of ORE15 - 87 - 3.4 Discussion - 94 - Summary in Korean - 109 - Acknowledgement - 112 - Curriculum Vitae - 113 -
