Parti: 13
The control of organ Shapes by the ANGUSTIFOLIA Gene in Arabidopsis
thaliana 13
ABSTRACT 14
INTRODUCTION 15
RESULT 17
Specificity of the AtMLl and PCAL promoters in Arabidopsis 17
Tissue layer specific expression of AN 19
ANGUSTIFOLIA^ cell autonomous control in cell polarity defect 20
The leaf width is only rescued by the subepidermis expression of AN 23
Leaf length is rescued by both epidermis and subepidermis expression of
AN 24
The petal and silique phenotype are rescued by the AN epidermis
expression 25
The epidermal cell number is controlled by a non-cell autonomous signal
from the subepidermis tissues 27
The crossed transgenic lines of an-X2;pATML::AN#4 and
an-X2;pPCAL::AN#20 show the normal leaf shape and trichome
branching. 28
DISCUSSION 30
Cell autonomous functioned A in regulating the epidermis cell polarity
phenotype 30
Non cell autonomous function of AN in regulating the epidermal cell
number 30
How is the leaf shape regulated by ANGUSTIFOLIA ? 30
Which is the shape giving tissue in Arabidopsis 32
Part 2: 33
AIK1, a protein kinase, regulates leaf and trichome development though
ANGUSTIFOLIA in Arabidopsis. 33
INTRODUCTION 34
RESULT 36
AIK1 interacts with ANGUSTIFOLIA in yeast and plant cells. 36
AN Interacting Kinase 1 (AIK1) encodes a protein kinase. 37
Null mutants of T-DNA lines for AIK1 are not available. 39
Both the aikl-s and aikl-w mutant show narrow cotyledons 40
Co-suppression and overexpression of AIK1 42
Artificial microRNA knock-down of AIK1 leads to the an-like
phenotypes. 43
DISCUSSION 47
AIK1 is a novel important gene involve in leaf and trichome
development. 47
AIK1 mutants show phenotypes in the same tendency. 47
AIK1 gene encodes a protein kinase. 48
AIK1 may be a positive regulator of AN. 48
Part 3: 50
Molecular Analysis of ANGUSTIFOLIA 50
INTRODUCTION 51
RESULT 53
AN forms a homo-dimer in vitro and in vivo. 53
Localization of AN 54
The N-terminal part is sufficient to rescue the an-2 mutant. 54
The C-terminal part of AN may negatively regulate /iVs function. 57
Asymetric leaf Enhancer 3 {AE3), a proteasome subunit protein. 58
Protein expression of AN 58
DISCUSSION 60
N-terminal part of AN is sufficient for its function. 60
The C-terminal part of AN might negatively regulate AN s function. 60
The localization of AN 61
ANGUSTIFOLIA is a plant member of the CtBP family. 61
