Transcriptome changes triggered by the loss of function of gene Mppcs in genome-edited Marchantia polymorpha plants

Project description:In the present study, Marchantia polymorpha Mppcs loss of function mutants were generated through CRISPR/cas9 mediated genome-editing. To assess whether the knockout of MpPCS gene affects the transcription of M. polymorpha nuclear genes in unstressed condition, the Mppcs-2 knockout mutant and Cam2 wild-type transcriptomes were compared by RNA-Seq.

Differential phosphoproteomics upon chitin- or blue-light treatment in Marchantia polymorpha

Project description:Pattern-recognition receptor (PRR)-triggered immunity (PTI) plays a pivotal role in plant immunity to ward off a wide range of pathogenic microbes. The model liverwort Marchantia polymorpha is gaining popularity in investigating the evolution of plant-microbe interactions. The M. polymorpha is capable of triggering defense-related gene expression by sensing components in bacterial and fungal extracts, suggesting existence of PTI in this plant model. However, the molecular components that would form PTI in M. polymorpha have not yet been described. We show that, in M. polymorpha, lysin motif (LysM) receptor-like kinase (LYK) MpLYK1 and LYK-related (LYR) MpLYR, among four LysM receptor homologs, are required for sensing chitin and peptidoglycan (PGN) fragments and thereby triggering a series of immune responses. Phosphoproteomic analysis of M. polymorpha in response to chitin treatment comprehensively identified regulatory proteins that would shape LysM-mediated PTI. The identified proteins covered homologs of well-described PTI components in angiosperms as well as proteins whose roles in PTI are not yet determined including the blue-light receptor phototropin MpPHOT. We revealed that MpPHOT is required for a negative feedback of defense-related gene expression during PTI. Taken together, this study provides the basic framework of LysM-mediated PTI in M. polymorpha and demonstrates the utility of M. polymorpha as a plant model for discovering novel or fundamental molecular mechanisms underlying PRR-triggered immune signaling in plants.

Proteomic data in Marchantia polymorpha accessions exposed to combined heat-drought stress

Project description:Marchantia polymorpha male (tak-1) and female (tak-2) accessions were subjected to a combined heat-drought stress in daily shocks of 1 hour long for two days, ending up with control samples, T1 and T2 stressed samples. Five biological replicates from both accessions were taking into account, all together resultig in 30 samples submitted to proteomic analysis.

A single JAZ repressor controls the jasmonate pathway in Marchantia polymorpha

Project description:JAZ genes are negative regulators of jasmonate responses with a dual function as repressors of transcription factors and co-receptors, together with COI1, of the hormone jasmonoyl-isoleucine (JA-Ile). This family has been mainly studied in angiosperms, where high gene redundancy hinders the characterization of a complete depletion of JAZ function. Moreover, the recent discovery that JA-Ile is not the sole COI1/JAZ ligand in land plants, as dn-OPDA is the bioactive ligand in Marchantia polymorpha, underscores the importance of studying JAZ co-receptors in bryophytes. Here we exploited the low gene redundancy of the liverwort Marchantia polymorpha to characterize the function of the single MpJAZ in this early-divergent plant lineage. We demonstrate that MpJAZ is the ortholog of AtJAZ and acts as a repressor of dinor-OPDA responses in Marchantia. Mpjaz mutants show a dwarf phenotype and severe developmental defects related to growth inhibition, consistent with a constitutive activation of the dinor-OPDA pathway and the overaccumulation of both dinor-OPDA and its precursor OPDA. The expression of AtJAZ3 in Mpjaz complements MpJAZ repressor function, indicating that JAZ function is conserved across land plants. However, AtJAZ3 is unable to form co-receptor complexes with MpCOI1 and dn-OPDA, which evidences that the Jas domain, and not only COI1, determines ligand specificity.
