Research Interests

Research in my lab focuses on the cellular signaling mechanisms that control plant growth and responses to the environment. Plant growth is highly modulated by environmental signals such as light and temperature, by endogenous hormones such as brassinosteroid (BR), auxin, gibberellic acid (GA), and abscisic acid (ABA), as well as by sugar. Our research is illustrating the complex molecular networks that integrate these environmental and endogenous signals with gene transcription, protein translation and modification, and cellular membrane organization, which drive cell division and expansion. We use a wide range of research approaches, including genetics, genomics, proteomics, and imaging in the model organisms of Arabidopsis and Chlamydomonas as well as maize. Our long-term goal is to improve plant productivity and resilience by engineering the cellular regulatory systems.

1. The brassinosteroid (BR) signaling pathway - the best-studied receptor kinase pathway in plants.

BR is a major growth-promoting hormone that regulates a wide range of developmental and physiological processes, including seed germination, cell elongation, growth, flowering, light responses, photosynthesis, and stress tolerance. Application of BR or increasing BR biosynthesis can enhance plant growth and biomass production. Research on BR has great potential of increasing crop yield.
BR is perceived by the cell-surface receptor kinase BRI1 (Figure 1), which contains an extracellular leucine-rich repeat domain and a cytoplasmic serine/threonine kinase domain. BR binding to the extracellular domain of BRI1 activates its kinase and initiates a signaling cascade leading to regulation of gene expression in the nucleus. This signaling cascade includes the BR-signaling kinases (BSKs), the PP1-like phosphatase BSU1, the GSK3-like kinase BIN2, and protein phosphatase 2A (PP2A), the phosphopeptide-binding 14-3-3 proteins, and the homologous transcription factors BZR1 and BZR2 (also named BES1). When BR level is high, BRI1 phosphorylates BSKs/CDG1 kinases which in turn phosphorylate BSU1. BSU1 dephosphorylates BIN2 to inhibit its kinase activity and to increase its ubiquitination mediated by the KIB1 E3 ubiquitin ligase. As such, BR induces rapid accumulation of dephosphorylated BZR1 and BZR2/BES1 in the nucleus due to dephosphorylation by PP2A. BZR1 and BZR2 directly regulate the expression of thousands of target genes. Our works have established the BR signaling pathway as the best-understood receptor-kinase signaling pathway in plants.

We have identified over one hundred substrates of the BIN2 kinase and dozens of interactors of BSL1 and BSL2, using TurboID proximity labeling and phosphoproteomics. We are developing synthetic protein interaction tools to study the functions of these protein interactions. Our current research focuses include:

1. How does GSK3 kinase BIN2 regulate its substrates involved in RNA splicing, translation, vesicle trafficking, and cell wall integrity.

2. How do the BSU family phosphatases regulate cell division, vesicle trafficking, and organ abscision.

3. How do receptor kinases crosstalk in maintaining cell wall integrity?

Figure 1)

2. Signal crosstalk and Integration of multiple pathways into networks

We have further gained insight into the molecular mechanisms that integrate BR with other major growth-regulation signals, including gibberellin (GA), auxin, light, temperature, pathogen signals, and nutrient signals. Using modern genomic approaches of RNA-Seq and ChIP-Seq, we have identified thousands of genes directly regulated by BZR1, the light-regulated transcription factor PIF4, and the auxin response factor 6 (ARF6). These genome-wide targets not only identify diverse cellular and developmental functions controlled by these signaling pathways, but also revealed extensive overlaps among the target genes these distinct transcription factors. We further discovered that these TFs directly interact with each other and also interact with the gibberellin (GA) signaling DELLA proteins. Our research has thus revealed a central growth-regulation (CGR) network that integrates multiple hormonal, environmental, and nutritional signals for regulation of shoot growth in plants (Figure 2). Our studies of root growth regulation uncovered a gradient of BR signal along the developmental gradient of stem cell differentiation and an antagonistic relationship between BR and auxin in regulating gene expression and cell elongation (Figure 3).

Currently, we are trying to answer the following questions:

1. How do interactions between transcription factors alter their target gene specificity and transcriptional activities?

2. How does BR signaling promote the transition from division to elongation in the root meristem?

3. How does BR signaling modulate auxin transport?

Figure 2)

3. Proteomic studies of signaling networks controlling growth and acclimation.

An emerging focus of the lab is proteomic studies of sugar signaling mechanisms and sugar-hormone crosstalk. Sugar signaling through protein modification by O-linked N-acetylglucosamine (O-GlcNAc), catalyzed by O-GlcNAc transferase (OGT) is an essential cellular regulatory mechanism in all eukaryotes. Arabidopsis has two OGT homologs: SPINDLY (SPY) and SECRET AGENT (SEC). Double spy sec mutants are embryo lethal, indicating their essential functions. Recent studies have shown that SPY is an O-fucosyl transferase, whereas SEC is an OGT. We are the first lab in the world that has reported proteomic profiling O-GlcNAc modifications in plants and we have identified 262 O-GlcNAcylated proteins in Arabidopsis. These are mostly nuclear proteins with regulatory functions including key components of hormonal pathways, and many of them are also phosphorylated in response to BR. We have also identified hundreds of O-fucosylated proteins. These studies are expanding the posttranslational modification networks through which sugar and hormones regulate plant growth and development.

Currently, we are working on the following questions:

(1) How do O-GlcNAc and O-fucose modifications regulate proteins involved in transcription, alternative RNA splicing, translation?

(2) How do sugar and steroid signals co-regulate plant growth through crosstalk between O-glycosylation and phosphorylation?

(3) How do sugar and steroid signals co-regulate RNA splicing, protein translation, stress responses, and primary metabolism through phosphorylation and glycosylation of common target proteins?

Profile

Bio

I am interested in how hormones regulate plant growth according to endogenous nutrient and energy status and environmental conditions. We use broad research approaches to dissect the molecular mechanisms by which plants perceive, transduce, and integrate internal and external signals into cellular decisions to divide, expand, differentiate, defend, or acclimate. Our goal is to understand the signaling and regulatory networks and to generate knowledge that enables engineering plants with enhanced yield and resilience.

I am interested in how plants coordinate cell growth and division. Brassinosteroid (BR) hormones are known for their growth-promoting activity, but also help regulate cell division in certain tissues. I am exploring mechanistic links between BR signaling and cell division, using Arabidopsis and the alga Chlamydomonas as models.
