Abstract
Several studies have documented that treatment by cold atmospheric pressure plasma (CAPP) on plants foster seed germination and growth in recent years. However, the molecular processes that underlie the action of CAPP on the seeds and plants remain mostly enigmatic. We here introduce gemmae of Marchantia polymorpha, a basal liverwort, as a novel model plant material suitable for CAPP research. Treating the gemmae with CAPP for a constant time interval at low power resulted in consistent growth enhancement, while growth inhibition at higher power in a dose-dependent manner. These results distinctly demonstrate that CAPP irradiation can positively and negatively regulate plant growth depending on the plasma intensity of irradiation, offering a suitable experimental system for understanding the molecular mechanisms underlying the action of CAPP in plants.

Abstract
The BAP module, comprising BRASSINAZOLE RESISTANT 1 (BZR1), AUXIN RESPONSE FACTOR 6 (ARF6), and PHYTOCHROME-INTERACTING FACTOR 4 (PIF4), functions as a molecular hub to orchestrate plant growth and development. In Arabidopsis thaliana, components of the BAP module physically interact to form a complex system that integrates light, brassinosteroid (BR), and auxin signals. Little is known about the origin and evolution of the BAP module. Here, we conducted comparative genomic and transcriptomic analyses to investigate the evolution and functional diversification of the BAP module. Our results suggest that the BAP module originated in land plants and that the ζ, ε, and γ whole-genome duplication/triplication events contributed to the expansion of BAP module components in seed plants. Comparative transcriptomic analysis suggested that the prototype BAP module arose in Marchantia polymorpha, experienced stepwise evolution, and became established as a mature regulatory system in seed plants. We developed a formula to calculate the signal transduction productivity of the BAP module and demonstrate that more crosstalk among components enables higher signal transduction efficiency. Our results reveal the evolutionary history of the BAP module and provide insights into the evolution of plant signaling networks and the strategies employed by plants to integrate environmental and endogenous signals.

Int J Mol Sci 2023; 24:ijms24087636. [PMID: 37108797 PMCID: PMC10142106 DOI: 10.3390/ijms24087636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 04/14/2023] [Accepted: 04/18/2023] [Indexed: 04/29/2023] Open
Abstract
Agrobacterium-mediated transient expression (AMTE) has been widely used for high-throughput assays of gene function in diverse plant species. However, its application in monocots is still limited due to low expression efficiency. Here, by using histochemical staining and a quantitative fluorescence assay of β-glucuronidase (GUS) gene expression, we investigated factors affecting the efficiency of AMTE on intact barley plants. We found prominent variation in GUS expression levels across diverse vectors commonly used for stable transformation and that the vector pCBEP produced the highest expression. Additionally, concurrent treatments of plants with one day of high humidity and two days of darkness following agro-infiltration also significantly increased GUS expression efficiency. We thus established an optimized method for efficient AMTE on barley and further demonstrated its efficiency on wheat and rice plants. We showed that this approach could produce enough proteins suitable for split-luciferase assays of protein-protein interactions on barley leaves. Moreover, we incorporated the AMTE protocol into the functional dissection of a complex biological process such as plant disease. Based on our previous research, we used the pCBEP vector to construct a full-length cDNA library of genes upregulated during the early stage of rice blast disease. A subsequent screen of the library by AMTE identified 15 candidate genes (out of ~2000 clones) promoting blast disease on barley plants. Four identified genes encode chloroplast-related proteins: OsNYC3, OsNUDX21, OsMRS2-9, and OsAk2. These genes were induced during rice blast disease; however, constitutive overexpression of these genes conferred enhanced disease susceptibility to Colletotrichum higginsianum in Arabidopsis. These observations highlight the power of the optimized AMTE approach on monocots as an effective tool for facilitating functional assays of genes mediating complex processes such as plant-microbe interactions.

Abstract
Marchantia polymorpha has emerged as a model liverwort species, with molecular tools increasingly available. In the present study, we developed an auxotrophic strain of M. polymorpha and an auxotrophic selective marker gene as new experimental tools for this valuable model system. Using CRISPR (clustered regularly interspaced palindromic repeats)/Cas9-mediated genome editing, we mutated the genomic region for IMIDAZOLEGLYCEROL-PHOSPHATE DEHYDRATASE (IGPD) in M. polymorpha to disrupt the biosynthesis of histidine (igpd). We modified an IGPD gene (IGPDm) with silent mutations, generating a histidine auxotrophic selective marker gene that was not a target of our CRISPR/Cas9-mediated genome editing. The M. polymorpha igpd mutant was a histidine auxotrophic strain, growing only on medium containing histidine. The igpd mutant could be complemented by transformation with the IGPDm gene, indicating that this gene could be used as an auxotrophic selective marker. Using the IGPDm marker in the igpd mutant background, we produced transgenic lines without the need for antibiotic selection. The histidine auxotrophic strain igpd and auxotrophic selective marker IGPDm represent new molecular tools for M. polymorpha research.

ANNALS OF BOTANY 2022; 130:457-475.

Abstract
BACKGROUND In this review, we summarize data concerning action potentials (APs) - long-distance electrical signals in Characean algae and liverworts. These lineages are key in understanding the mechanisms of plant terrestrialization. Liverworts are postulated to be pioneer land plants, whereas aquatic charophytes are considered the closest relatives to land plants. The drastic change of the habitat was coupled with the adaptation of signalling systems to the new environment. SCOPE APs fulfil the 'all-or-nothing' law, exhibit refractory periods and propagate with a uniform velocity. Their ion mechanism in the algae and liverworts consists of a Ca2+ influx (from external and internal stores) followed by/coincident with a Cl- efflux, which both evoke the membrane potential depolarization, and a K+ efflux leading to repolarization. The molecular identity of ion channels responsible for these fluxes remains unknown. Publication of the Chara braunii and Marchantia polymorpha genomes opened up new possibilities for studying the molecular basis of APs. Here we present the list of genes which can participate in AP electrogenesis. We also point out the differences between these plant species, e.g. the absence of Ca2+-permeable glutamate receptors (GLRs) and Cl--permeable SLAC1 channel homologues in the Chara genome. Both these channels play a vital role in long-distance signalling in liverworts and vascular plants. Among the common properties of APs in liverworts and higher plants is their duration (dozens of seconds) and the speed of propagation (mm s-1), which are much slower than in the algae (seconds, and dozens of mm s-1, respectively). CONCLUSIONS Future studies with combined application of electrophysiological and molecular techniques should unravel the ion channel proteins responsible for AP generation, their regulation and transduction of those signals to physiological responses. This should also help to understand the adaptation of the signalling systems to the land environment and further evolution of APs in vascular plants.

Functional Analyses of the Two Distinctive Types of Two-Pore Channels and the Slow Vacuolar Channel in Marchantia polymorpha. PLANT & CELL PHYSIOLOGY 2022; 63:163-175. [PMID: 34936705 DOI: 10.1093/pcp/pcab176] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 11/23/2021] [Accepted: 12/22/2021] [Indexed: 06/14/2023]
Abstract
The two-pore channel (TPC) family is widely conserved in eukaryotes. Many vascular plants, including Arabidopsis and rice, possess a single TPC gene which functions as a slow vacuolar (SV) channel-voltage-dependent cation-permeable channel located in the vacuolar membrane (tonoplast). On the other hand, a liverwort Marchantia polymorpha genome encodes three TPC homologs: MpTPC1 is similar to TPCs in vascular plants (type 1 TPC), while MpTPC2 and MpTPC3 are classified into a distinctive group (type 2 TPC). Phylogenetic analysis suggested that the type 2 TPC emerged before the land colonization in plant evolution and was lost in vascular plants and hornworts. All of the three MpTPCs were shown to be localized at the tonoplast. We generated knockout mutants of tpc1, tpc2, tpc3 and tpc2 tpc3 double mutant by clustered regularly interspaced short palindromic repeats/Cas9 genome editing and performed patch-clamp analyses of isolated vacuoles. The SV channel activity was abolished in the Mptpc1 loss-of-function mutant (Mptpc1-1KO), while Mptpc2-1KO, Mptpc3-1KO and Mptpc2-2/tpc3-2KO double mutant exhibited similar activity to the wild type, indicating that MpTPC1 (type 1) is solely responsible for the SV channel activity. Activators of mammalian TPCs, phosphatidylinositol-3,5-bisphosphate and nicotinic acid adenine dinucleotide phosphate, did not affect the ion channel activity of any MpTPCs. These results indicate that the type 1 TPCs, which are well conserved in all land plant species, encode the SV channel, while the type 2 TPCs likely encode other tonoplast cation channel(s) distinct from the SV channel and animal TPCs.

Abstract
Genetic modifications such as mutation and transformation are powerful tools to study the function of genes and proteins in the model liverwort Marchantia polymorpha, but maintaining the resulting germplasm requires a practical, reliable method. Cryopreservation methods allow researchers to maintain mutant and transgenic lines of M. polymorpha. To date, two methods have been developed for cryopreservation of M. polymorpha gemmae: in the first method, unencapsulated gemmae are stored in liquid nitrogen at −196 °C, and in the second method, encapsulated gemmae are stored in liquid nitrogen at −196 °C or a deep freezer at −80 °C. In the present study, we developed a simple method named CRUNC (cr yopreservation of un en c apsulated gemmae), which can be used to store unencapsulated, dried gemmae of wild-type and transgenic M. polymorpha lines in liquid nitrogen and in freezers at −80 °C and −20 °C. Using the CRUNC method, we observed a high recovery rate (as high as 100%) and successful long-term (5 months) storage of the gemmae. Therefore, the CRUNC method is practical for maintaining valuable M. polymorpha germplasm.

Abstract
Marchantia polymorpha is a model liverwort for which many molecular biological techniques are now available. We previously developed the S-AgarTrap method for easy genetic transformation of M. polymorpha using spores. In this study, we report production of a T-DNA insertion mutant library (approx. 10,000 lines) for M. polymorpha using the S-AgarTrap method. We further isolate and characterize a gain-of-function mutant that hyper-accumulates the flavonoid riccionidin A. The present study demonstrates that the S-AgarTrap-mediated production of a T-DNA insertion mutant library is a powerful tool for molecular biology in M. polymorpha.
