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.

Co-option of transcriptional hub expanded triangular functional interactions among nutrients during plant terrestrialzation

Project description:Plant nitrate, phosphate, and sucrose responses create a complex molecular network fine-tuned for growth and survival. This triangular interplay, crucial for the adaptability of terrestrial plants, allows the availability of one nutrient to influence plant responses to others. However, the origins and functional repurposing of this complex network for plant terrestrialization remain scarcely understood. By delving into the time-series transcriptome responses to nitrate, phosphate, and sucrose in the bryophyte Marchantia polymorpha and its streptophycean algal relatives Klebsormidium nitens, we observed convergent yet largely species-specific regulatory circuits in nutrient response. A key gene regulatory network (GRN) module centered on MpCSD, MpERF20, and MpHD9 was found to govern the hierarchical responses and crosstalk among the three nutrients in M. polymorpha. In K. nitens, these transcription factors were involved in nutrient responses but were co-opted during phytoterrestrialization to serve additional functions. Further network perturbation experiments validated the extensive evolution of transcriptional targets of these regulatory circuits, with cytokinin responsive genes being recruited exclusively into macronutritional GRNs in M. polymorpha thus optimizing nutrient response. Our findings illuminate the evolutionary strategies employed to redeploy the triad of nutrient interactions during the adaptation of ancestral green plants to terrestrial habitats.

Effect of PRC2 loss of function on gene and TE expression in Marchantia polymorpha

Project description:To evaluate role of PRC2 on transcriptional regulation in bryophytes, we generated loss of function mutants of a Ez homolog in Marchantia polymorpha by CRISPR/Cas9 based mutagenesis. To avoid lethality of PRC2 knockout, we first mutate MpKNOX2 gene then additionally knocked MpEz1 out. Then we performed comparative transcriptome analyses using data obtained from Mpknox2 ez1 and Mpknox2.
