Green revolution: A mutant gibberellin-synthesis gene in rice
The chronic food shortage that was feared after the rapid expansion of the world population in the 1960s was averted largely by the development of a high-yielding semi-dwarf variety of rice known as… Expand
Gibberellin Modulates Anther Development in Rice via the Transcriptional Regulation of GAMYB[W]
Gibberellins (GAs) play important roles in regulating reproductive development, especially anther development. Our previous studies revealed that the MYB transcriptional factor GAMYB, an important… Expand
Structural basis for gibberellin recognition by its receptor GID1
Gibberellins (GAs) are phytohormones essential for many developmental processes in plants. A nuclear GA receptor, GIBBERELLIN INSENSITIVE DWARF1 (GID1), has a primary structure similar to that of the… Expand
Identification, isolation and pyramiding of quantitative trait loci for rice breeding.
Many agronomically important traits are governed by several genes known as quantitative trait loci (QTLs). The identification of important, QTL-controlled agricultural traits has been difficult… Expand
GID1-mediated gibberellin signaling in plants.
Gibberellin (GA) perception is mediated by GID1 (GA-INSENSITIVE DWARF1), a receptor that shows similarity to hormone-sensitive lipases. A key event in GA signaling is the degradation of DELLA… Expand
DIFFERENTIAL REGULATION OF PHENYLALANINE AMMONIA-LYASE GENES DURING ANTHOCYANIN SYNTHESIS AND BY TRANSFER EFFECT IN CARROT CELL SUSPENSION CULTURES
Phenylalanine ammonia-lyase (PAL; EC 184.108.40.206) catalyses the first step in the phenylpropanoid pathway and is induced during differentiation and by various stimuli. In carrot (Daucus carota L. cv.… Expand
Functional analysis of cotton orthologs of GA signal transduction factors GID1 and SLR1
Gibberellic acid (GA) is both necessary and sufficient to promote fiber elongation in cultured fertilized ovules of the upland cotton variety Coker 312. This is likely due to the temporal and spatial… Expand

In Arabidopsis, three receptors exist for the phytohormone gibberellin. Of the three, only a double loss-of-function mutant (atgid1a atgid1c) shows a dwarf phenotype, while other double and all… Expand

The organ size of flowering plants is determined by two post-embryonic developmental events: cell proliferation and cell expansion. In this study, we identified a new rice loss-of-function mutant,… Expand
Characterization of CONSTITUTIVE PHOTOMORPHOGENESIS AND DWARFISM Homologs in Rice (Oryza sativa L.)
To enhance our understanding of brassinosteroid (BR) biosynthesis in rice, we attempted to identify putative rice homologs of Arabidopsis CYP90A1/ CPD and related mutants. Two candidate genes,… Expand
