| Abstract |
Transcription factors that act as positive regulators of gibberellin (GA) biosynthetic genes in plants are not well understood. A nuclear-localized basic leucine zipper transcription factor, ZmGRF, was isolated from maize. The core DNA sequence motif recognized for binding by ZmGRF was CCANNTGGC. ZmGRF overexpression in transgenic Arabidopsis plants promoted flowering, stem elongation, and cell expansion. Chromatin immunoprecipitation assays revealed that ZmGRF bound directly to the cis-element CCANNTGGC in the promoter of the Arabidopsis ent-kaurene oxidase (AtKO1) gene and promoted AtKO1 expression. GA4 content increased by 372-567 % in transgenic Arabidopsis plants overexpressing ZmGRF compared to wild-type control plants. The GIBBERELLIN-INSENSITIVE DWARF1 gene, which encodes a GA receptor, was also upregulated and the growth-repressing DELLA protein gene GA INSENSITIVE was downregulated. Our results showed ZmGRF functioned through the GA-signaling pathway. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 December 2014.
All research outputs
#20,245,139
of 22,772,779 outputs
Outputs from Plant Molecular Biology
#2,623
of 2,846 outputs
Outputs of similar age
#301,396
of 359,774 outputs
Outputs of similar age from Plant Molecular Biology
#10
of 14 outputs
Altmetric has tracked 22,772,779 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,846 research outputs from this source. They receive a mean Attention Score of 4.3. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 359,774 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 14 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
