Abstract:

The brassinazole-resistant (BZR) transcription factors (TFs) are key components of brassinosteroid (BR) signaling, which play an important role in regulating plant growth and development as well as responding to abiotic stress. However, a functional study of BZR transcription factors in lotuses has not been reported. A total 10 BZR1 genes (four NnBZR1 and six NlBZR1) were identified from the genomes of two lotus species (Nelumbo nucifera and Nelumbo lutea). The construction of the phylogenetic tree showed that the 10 BZR1 genes of the lotus were divided into four groups; the NnBZR1s and NlBZR1

Abstract:

In model plants, the BRI1-EMS suppressor 1 (BES1)/brassinazole-resistant 1 (BZR1) transcription factors play vital roles in regulating growth, development, and stimuli response. However, the roles of maize ZmBES1/BZR1 members are largely unknown. In this research, the ZmBES1/BZR1-9 gene was ectopically expressed in Arabidopsis and rice for the phenotyping of flowering. We found that the complementation and overexpression of ZmBES1/BZR1-9 in bes1-D mutant and wild type Arabidopsis both resulted in early flowering that was about 10 days shorter than in the untransformed control under long-day co

Abstract:

Regulation of the nucleocytoplasmic trafficking of signaling components, especially transcription factors, is a key step of signal transduction in response to extracellular stimuli. In the brassinosteroid (BR) signal transduction pathway, transcription factors from the BRASSINAZOLE RESISTANT1 (BZR1) family are essential in mediating BR-regulated gene expression. The subcellular localization and transcriptional activity of BZR1 are tightly regulated by reversible protein phosphorylation; however, the underlying mechanism is not well understood. Here, we provide evidence that both BZR1 phosphory

Bri1-EMS Suppressor 1 (BES1) and Brassinazole Resistant 1 (BZR1) are two key transcription factors in the brassinosteroid (BR) signaling pathway, serving as crucial integrators that connect various signaling pathways in plants.

Abstract:

Brassinosteroids (BRs) play crucial roles in the physiology and development of plants. In the model plant Arabidopsis, BR signaling is initiated at the level of membrane receptors, BRASSINOSTEROIDS INSENSITIVE 1 (BRI1) and BRI1-ASSOCIATED RECEPTOR KINASE 1 (BAK1) complex, thus activating the transcription factors (TFs) BRASSINAZOLE RESISTANT 1/BRI1-EMS-SUPPRESSOR 1 (BZR1/BES1) to coordinate BR responsive genes. BRASSINOSTEROIDS INSENSITIVE 2 (BIN2), glycogen synthase kinase 3 (GSK3) like-kinase, negatively regulates BZR1/BES1 transcriptional activity through phosphorylation-dependent cytosolic

Abstract:

The BR-responsive genes are then regulated by BRASSINAZOLERESISTANT (BZR) Transcription Factors (TFs). As BRs possess numerous stress-resistant functions, BZR TFs also show activities of stress-resistance along with other developmental functions. Up to 88% similarity of protein sequences has been observed between BZR1 and BZR2 genes. Many positive roles of BZR TFs have been revealed by many studies in positively regulating the BR signal transduction in rice and maize family, but there is a very limited research is available on the BZR gene family of Zea mays. The aim of this study is to perfor

SUMMARYBES1/BZR1, a kind of plant‐specific transcription factor (TF), has been reported to regulate growth, development, and stress response. However, the maize BES1/BZR1 members are still largely unknown. In this study, we investigated the function and regulatory mechanism of maize ZmBES1/BZR1‐4 in regulating drought response and seed development. The ZmBES1/BZR1‐4 was localized in the nucleus depending on its bHLH domain and showed no self‐transactivation activity. The transcription level of ZmBES1/BZR1‐4 was induced by drought stress and was predominantly higher in seeds 25 days after polli

Abstract Brassinosteroids (BRs) are phytohormones that regulate stomatal development BRASSINAZOLE RESISTANT 1. In this study, we report that BR represses stomatal development in etiolated Arabidopsis (Arabidopsis thaliana) cotyledons via transcription factors BRASSINAZOLE RESISTANT 1 (BZR1) and bri1-EMS SUPPRESSOR1 (BES1), which directly target MITOGEN-ACTIVATED PROTEIN KINASE KINASE 9 (MKK9) and FAMA, two important genes for stomatal development.

Recently, this MBP-mediated crystallization technique was adapted to Arabidopsis thaliana (At) BRZ-INSENSITIVE-LONG (BIL1)/BRASSINAZOLE-RESISTANT (BZR1), a member of the plant-specific BZR TFs, and revealed the first structure of AtBIL1/BZR1 in complex with target DNA. However, it is unclear how the fused MBP affects the structural features of the AtBIL1/BZR1-DNA complex. In the present study, we highlight the potential utility of the MBP crystallizatio

Abstract A well-constructed pollen wall is essential for pollen fertility, which relies on the contribution of tapetum. Our results demonstrate an essential role of the tapetum-expressed protein phosphatase 2A (PP2A) B’α and B’β in pollen wall formation. The b’aβ double mutant pollen grains harbored sticky remnants and tectum breakages, resulting in failed release. B’α and B’β function partially through dephosphorylating and activating BZR1. The bzr1 bes1 double and higher-order mutants of this family displayed similar defects in pollen wall, while bzr1-1D, having an active mBZR1 exhibited fer

Abstract:

SUMMARYBrassinazole Resistant 1 (BZR1) and bri1 EMS Suppressor 1 (BES1) are key transcription factors that mediate brassinosteroid (BR)‐responsive gene expression in Arabidopsis. The BZR1/BES1 family is composed of BZR1, BES1, and four BES1/BZR1 homologs (BEH1–BEH4). However, little is known about whether BEHs are regulated by BR signaling in the same way as BZR1 and BES1. We comparatively analyzed the functional characteristics of six BZR1/BES1 family members and their regulatory mechanisms in BR signaling using genetic and biochemical analyses. We also compared their subcellular localization

Abstract:

Light and brassinosteroid (BR) are master environmental stimulus and endogenous cue for plant growth and development respectively. Great progress has been made in elucidating the molecular mechanisms on the cross-talk between light and BR. However, little is known about how BZR1, the pivotal integration node, is regulated by light and dark. Here, we demonstrated that an intact BR signaling pathway is essential for dark-induced hypocotyl elongation. Consequent expression assay showed that light–dark switch affected BZR1 phosphorylation and accumulation. Moreover, blocking the 26S proteasome pat

Abstract:

Although it is known that brassinosteroids (BRs) play pleiotropic roles in plant growth and development, their roles in plant nutrient uptake remain unknown. Here, we hypothesized that BRs directly regulate ammonium uptake by activating the expression of rice AMT1-type genes. Exogenous BR treatment upregulated both AMT1;1 and AMT1;2 expression, while this induction was impaired in the BR-receptor gene BRI1 mutant d61-1. We then focused on brassinazole-resistant 1 (BZR1), a central hub of the BR signaling pathway, demonstrating the important role of this signaling pathway in regulating AMT1 exp

Abstract:

The molecular mechanisms underlying the trade-off between plant innate immunity and steroid-mediated growth are controversial. Here, we report that activation of the transcription factor BZR1 is required and sufficient for suppression of immune signaling by brassinosteroids (BR). BZR1 induces the expression of several WRKY transcription factors that negatively control early immune responses. In addition, BZR1 associates with WRKY40 to mediate the antagonism between BR and immune signaling. We reveal that BZR1-mediated inhibition of immunity is particularly relevant when plant fast growth is re
