The transcription factor AtGRF5 and the transcription coactivator AN3 regulate cell proliferation in leaf primordia of Arabidopsis thaliana.
TLDR
Describing two genes from Arabidopsis thaliana suggest that AN3 and AtGRF5 act together and are required for the development of appropriate leaf size and shape through the promotion and/or maintenance of cell proliferation activity in leaf primordia. Expand
Cell cycling and cell enlargement in developing leaves of Arabidopsis.
TLDR
It is indicated that cell cycling related to leaf morphogenesis, tissue-specific patterns of cell proliferation, and cell differentiation occurs concurrently during leaf development and suggest that unique regulatory pathways may operate at each level. Expand
The ASYMMETRIC LEAVES2 gene of Arabidopsis thaliana, required for formation of a symmetric flat leaf lamina, encodes a member of a novel family of proteins characterized by cysteine repeats and a
TLDR
The results suggest that AS2 functions in the transcription of a certain gene(s) in plant nuclei and thereby controls the formation of a symmetric flat leaf lamina and the establishment of a prominent midvein and other patterns of venation. Expand
The ASYMMETRIC LEAVES2 gene of Arabidopsis thaliana regulates formation of a symmetric lamina, establishment of venation and repression of meristem-related homeobox genes in leaves.
TLDR
The results suggest that AS2 and AS1 might be involved in establishment of a prominent midvein and of networks of other veins as well as in the formation of the symmetric leaf lamina, which might be related to repression of class 1 knox homeobox genes in leaves. Expand
Two independent and polarized processes of cell elongation regulate leaf blade expansion in Arabidopsis thaliana (L.) Heynh.
TLDR
It is proposed that leaf expansion in Arabidopsis involves at least two independent developmental processes: width development and length development, with the ANGUSTIFOLIA and ROTUNDIFOLia3 genes playing different polarity-specific roles in cell elongation. Expand
Biological functions of proline in morphogenesis and osmotolerance revealed in antisense transgenic Arabidopsis thaliana.
TLDR
Results indicate that Pro is not just an osmoregulator in stressed plants but has a unique function involved in osmotolerance as well as in morphogenesis as a major constituent of cell wall structural proteins in plants. Expand
Keep an Eye on PPi: The Vacuolar-Type H+-Pyrophosphatase Regulates Postgerminative Development in Arabidopsis[C][W][OA]
TLDR
It is demonstrated that the hydrolysis of cytosolic PPi, rather than vacuolar acidification, is the major function of AVP1/FUGU5 in planta and plant cells optimize their metabolic function by eliminating PPi in the cytosol for efficient postembryonic heterotrophic growth. Expand
The ROTUNDIFOLIA3 gene of Arabidopsis thaliana encodes a new member of the cytochrome P-450 family that is required for the regulated polar elongation of leaf cells.
TLDR
The results imply that the ROT3 protein is a member of a new class of cytochrome P-450 encoding putative steroid hydroxylases, which is required for the regulated polar elongation of cells in leaves of Arabidopsis. Expand
The ANGUSTIFOLIA gene of Arabidopsis, a plant CtBP gene, regulates leaf‐cell expansion, the arrangement of cortical microtubules in leaf cells and expression of a gene involved in cell‐wall formation
TLDR
It is found that the abnormal arrangement of cortical microtubules in an leaf cells appeared to account entirely for the abnormal shape of the cells, and it was suggested that the AN gene might regulate the polarity of cell growth by controlling the arrangement of cortex MTs. Expand
Involvement of Auxin and Brassinosteroid in the Regulation of Petiole Elongation under the Shade1[W]
TLDR
It is demonstrated that both auxin and brassinosteroid (BR) are required for the normal leaf responses to shade in Arabidopsis and cooperatively promote petiole elongation in response to the shade stimulus under the control of phytochrome in the leaf blade. Expand
