LZY-interacting proteins in Arabidopsis

ABSTRACT: In many plant species, roots maintain specific growth angles relative to the direction of gravity, known as gravitropic set point angles (GSA). These contribute to the efficient acquisition of water and nutrients. AtLAZY1/LAZY1-LIKE (LZY) genes are involved in GSA control by regulating auxin flow toward the direction of gravity in Arabidopsis. LZYs are plant-specific unknown proteins with no domain for which the function is inferable. To clarify the molecular function of LZYs, we identified the proteins that interact with them by immunoprecipitation coupled with mass spectrometry.

In many plant species, roots maintain specific growth angles relative to the direction of gravity, known as gravitropic set point angles (GSAs). These contribute to the efficient acquisition of water and nutrients. AtLAZY1/LAZY1-LIKE (LZY) genes are involved in GSA control by regulating auxin flow toward the direction of gravity in Arabidopsis. Here, we demonstrate that RCC1-like domain (RLD) proteins, identified as LZY interactors, are essential regulators of polar auxin transport. We show that ...[more]

Protein interaction partners of FRUITFULL in inflorescence meristems and pistils by IP-MS.

Project description:To study the possibility that the tissue-specific gene targets and regulation by FUL are due to a different composition in the FUL transcription factor (TF) protein complex/es in both tissues, we determined the protein-protein interactions of FUL in planta. Inflorescence meristems (IMs) of 35S:AP1-GR ap1 cal pFUL:FUL-GFP plants were collected to identify meristem-specific protein complexes of FUL, and stage 12 - 16 pistils of pFUL:FUL-GFP ful-1 plants were collected for the pistil-specific FUL protein complexes. Protein complexes were isolated by immunoprecipitation (IP) using anti-GFP antibodies and protein identification was performed using LC-MS/MS, followed by label-free protein quantification.

Pseudouridine guides germline small RNA transport and epigenetic inheritance

Project description:Epigenetic modifications that arise during plant and animal development, such as DNA and histone modification, are mostly reset during gamete formation, but some are inherited from the germline including those marking imprinted genes. Small RNAs guide these epigenetic modifications, and some are also inherited by the next generation. In C. elegans, inherited small RNA precursors have poly (UG) tails, but how inherited small RNAs are distinguished in other animals and plants is unknown. Pseudouridine (Ψ) is the most abundant RNA modification but has not been explored in small RNAs. Here, we develop novel assays to detect Ψ in short RNA sequences, demonstrating its presence in mouse and Arabidopsis microRNAs and their precursors. We also detect substantial enrichment in germline small RNAs, namely epigenetically activated siRNAs (easiRNAs) in Arabidopsis pollen, and piwi-interacting piRNAs in mouse testis. In pollen, pseudouridylated easiRNAs are localized to sperm cells, and we found that PAUSED/HEN5 (PSD), the plant homolog of Exportin-t, interacts genetically with Ψ and is required for transport of easiRNAs into sperm cells from the vegetative nucleus. We further show that Exportin-t is required for the triploid block: chromosome dosage-dependent seed lethality that is epigenetically inherited from pollen. Thus, Ψ has a conserved role in marking inherited small RNAs in the germline.

CUL3(BPM) E3 ubiquitin ligases regulate MYC2, MYC3 and MYC4 stability and JA responses

Project description:The Jasmonate pathway regulators MYC2, MYC3 and MYC4 are central nodes in plant signaling networks integrating environmental and developmental signals to fine-tune jasmonate defenses and plant growth. Hence, their activity needs to be tightly regulated in order to optimize plant fitness. Among the increasing number of mechanisms regulating MYCs, protein stability is arising as a major player. However, how the levels of MYCs proteins are modulated is still poorly understood. Here, we report that MYC2, MYC3 and MYC4 are targets of BPM proteins, which act as substrate adaptors of CUL3-based E3 ubiquitin ligases. Reduction-of-function of CUL3(BPM) in amiR-bpm lines, bpm235 triple mutants and cul3ab double mutants enhance MYC2 and MYC3 stability and accumulation, and potentiates plant responses to JA such a root-growth inhibition, and MYC-regulated gene expression. BPM3 protein is stabilized by JA, suggesting a new negative feedback regulatory mechanism to control MYCs activity. Our results uncover a new layer for JA-pathway regulation by CUL3(BPM)-mediated degradation of MYC TFs.

The Arabidopsis Mediator complex subunit 8 regulates oxidative stress responses

Project description:Hydrogen peroxide (H2O2) signals regulate plant growth and defense by orchestrating genome-wide transcriptional re-programming, however, the specific mechanisms that regulate H2O2-dependent gene expression are poorly understood. Here we report the identification of the Mediator complex subunit MED8 as regulator of H2O2 responses, through a genetic screen of EAL4 promoter. Interestingly, the introduction of med8 mutation in the catalase-deficient background was associated with enhanced activation of salicylic acid biosynthesis and signaling pathways. Surprisingly, however, med8 seedlings were more tolerant to oxidative stress generated by methyl viologen. This tolerance phenotype is associated with the hyperactivation of defense and hormone signaling pathways in particular salicylic acid and jasmonic acid-related pathways. In addition, analysis of MED8 interactomes revealed interaction with novel pathways expanding Mediator complex function to processes beyond transcription, including miRNA biogenesis and and mRNA processing. We establish MED8 as a new component within the regulation of oxidative stress responses and demonstrate that MED8 act as negative regulator of H2O2 -driven activation of defense gene expression.

Project description:We've demonstrated that plants are resistant to the overexpression of polyglutamine (polyQ) extended proteins that cause protein aggregation and Huntington's disease in human cells. To investigate which proteins, maintain polyQ proteins correctly folded and avoid polyQ aggregates in plant cells. Our goal is to identify therapeutic candidate proteins that can potentially be used to treat Huntington's disease in human cell models.

The Arabidopsis TETRATRICOPEPTIDE-REPEAT THIOREDOXIN-LIKE (TTL) family members are involved in root system formation via their interaction with cytoskeleton and cell wall remodeling

Project description:Lateral roots are essential components of the plant edaphic interface; contributing to water and nutrient uptake, biotic and abiotic interactions, stress survival, and plant anchorage. We have identified the TETRATRICOPEPTIDE-REPEAT THIOREDOXIN-LIKE 3 (TTL3) gene as being related to lateral root emergence and later development. Loss of function of TTL3 leads to a reduced number of emerged lateral roots due to delayed development of lateral root primordia. This trait is further enhanced in the triple mutant ttl1ttl3ttl4. TTL3 interacts with microtubules and endomembranes and is known to participate in the brassinosteroid signaling pathway. Both ttl3 and ttl1ttl3ttl4 mutants are less sensitive to brassinosteroid treatment in terms of lateral root formation and primary root growth. The ability of TTL3 to modulate biophysical properties of the cell wall was established under restrictive conditions of hyperosmotic stress and loss of root growth recovery, which was enhanced in ttl1ttl3ttl4. Timing and spatial distribution of TTL3 expression is consistent with its role in development of lateral root primordia before their emergence and subsequent growth of lateral roots. TTL3 emerged as a novel component of the root system morphogenesis regulatory network.
