2017年10月23日 · PRE1/BANQUO1 (BNQ1)/BHLH136 is one of the first identified PRE transcription factors. It was identified by screening Arabidopsis activation-tagged transgenic lines with enhanced resistance to Paclobutrazol (Lee et al., 2006).

2022年3月23日 · PRE1/BANQUO1 ( (BNQ1)/bHLH136) was initially identified as a positive regulator of the gibberellin (GA) response. The PRE1 transcription level is increased by GA signaling through GID receptor- and DELLA-dependent mechanisms, demonstrated in gibberellin-mediated seed germination, hypocotyl/petiole elongation, flower induction, and fruit ...
Triple Helix-Loop-Helix/Basic Helix-Loop-Helix Cascade Controls …
2012年12月7日 · Here, we show that IBH1 interacts with and inhibits a DNA binding basic helix-loop-helix (bHLH) protein, HBI1, in Arabidopsis thaliana. Overexpression of HBI1 increased hypocotyl and petiole elongation, whereas dominant inactivation of HBI1 and its homologs caused a dwarf phenotype, indicating that HBI1 is a positive regulator of cell elongation.
PRE1 basic helix-loop-helix (bHLH) DNA-binding family protein ...
2024年9月18日 · Summary Encodes PRE1 (PACLOBUTRAZOL RESISTANCE1). PRE1 and IBH1 form a pair of antagonistic HLH/bHLH transcription factors that function downstream of BZR1 to mediate brassinosteroid regulation of cell elongation. BNQ1 is directly and negatively regulated by AP3 and PI in petals.Required for appropriate regulation of flowering time. NEW
The Arabidopsis Floral Homeotic Proteins APETALA3 and …
2010年3月19日 · Consistent with a role in light response, we show that the BNQ gene products regulate the function of HFR1 (for LONG HYPOCOTYL IN FAR-RED1 ), which encodes a bHLH protein that regulates photomorphogenesis through modulating phytochrome and cryptochrome signaling. The BNQ genes also are required for appropriate regulation of flowering time.
In Situ Expression Analyses of BNQ Family Members. (A) to (F ...
BNQ1 expression is detectable in the sepals of wild-type flowers at stage 5 ( Figure 3 B). Prior to stage 5, BNQ1 transcripts cannot be detected in the flowers, although expres- sion is strong in...
Phenotypic, genetic and molecular characterization of
2017年8月16日 · BNQ1, together with its paralogs, are atypical members of the basic helix–loop–helix (bHLH) family of transcription regulators that integrates multiple signaling pathways (gibberellin, light, brassinosteroids; Lee et al. 2006).
