To gain insight into the evolution of this mechanism, we investigated their roles in leaves excised from Physcomitrium patens, a bryophyte known for its remarkable cell reprogramming capacity. We used various approaches to manipulate auxin levels, including exogenous application, pharmacological manipulations, and auxin biosynthesis mutants. We observed no significant effect on the rate of cell reprogramming. Rather, our analysis of auxin dynamics revealed a decrease in auxin levels upon excision, which was followed by a local increase before the reprogramming process began. Mutant analysis revealed that PpPINs are required for effective cell reprogramming, and endogenously expressed PpPINA-GFP accumulates polarly at sites that will develop into future filamentous stem cells. In addition, hyperpolarized PpPINA variants carrying mutated phosphorylation sites showed a marked delay in reprogramming, whereas endogenous or non-polar versions do not have this effect. These results underscore that both, the levels and the polarity of PpPINA are important for efficient cell reprogramming. Overall, these findings highlight the pivotal role of PIN polarity in plant regeneration. Furthermore, they suggest that understanding polarity mechanisms could have broader implications for improving regenerative processes across various plant species.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143010287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such circumstances, virus-plant interactions are expected to change significantly between the warm and cold seasons. However, few studies have investigated the effects of cold temperatures on virus-plant interactions. Here, we show that in a persistent infection system of the turnip mosaic virus (TuMV) -Arabidopsis halleri, cold temperatures lead to slow viral replication/spreading within the host, slow attenuation of host symptoms, and slow cold-specific transcriptomic responses. Many differentially expressed genes (DEGs) were detected between virus-inoculated and mock-inoculated plants under warm and cold conditions; however, the sets of DEGs and response timings were temperature-dependent. Under cold temperatures, the expression of photosynthesis-related genes decreased in the early stages of infection. However, it recovered to the same level as that in uninfected plants in the later stages. In contrast, the transcriptomic changes under warm conditions suggest that viral infections cause auxin-signaling disruption. These responses coincided with the inhibition of host growth. We identified 6 cold- and 38 warm-specific DEGs, that changed their expression in response to TuMV infection under more than half of the conditions for either cold or warm temperatures. Further validation of the putative relationships between transcriptomic and phenotypic responses of the host is required. Our findings on temperature-dependent host responses at both symptomatic and transcriptomic levels help us understand how warm and cold temperatures affect virus-plant interactions in seasonal environments.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143010290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The repertoires of miRNA genes vary drastically even among closely related species, indicating that they are evolutionarily labile. However, the processes by which they originate over the course of evolution and the nature of their progenitors across the genome remain poorly understood. Here we analyzed miRNA genes in Arabidopsis halleri, a plant species where we recently documented a large number of species-specific miRNA genes, likely to represent recent events of emergence. Analysis of sequence homology across the genome indicates that a diversity of sources contributes to the emergence of new miRNA genes, including inverted duplications from protein-coding genes, rearrangements of transposable element sequences and duplications of preexisting miRNA genes. Our observations indicate that the origin from protein-coding genes was less common than was previously considered. In contrast, we estimate that almost half of the new miRNA genes likely emerged from transposable elements. Miniature inverted transposable elements (MITE) seem to be particularly important contributors to new miRNA genes, with the Harbinger and Mariner transposable element superfamilies representing disproportionate sources for their emergence. We further analyzed the recent expansion of a miRNA family derived from MuDR elements, and the duplication of miRNA genes formed by two hAT transposons. Overall, our results illustrate the rapid pace at which new regulatory elements can arise from the modification of preexisting sequences in a genome, and highlight the central role of certain categories of transposable elements in this process.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143010309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bai et al. (2018) proved that SmERF6 binds to the promoter regions of Copalyl pyrophosphate synthase (CPS) and Kaurene synthase like (KSL) genes, and improves transcription, thereby, augmenting ferruginol levels, a common precursor for abietane diterpenes in Salvia genus, moreover, transgenic hairy roots of S. miltiorrhiza displayed four fold improved tanshinone content. In our study, heterologous transient expression of SmERF6 in S. officinalis exhibited inter-specific activity in promoting differential accumulation of diterpenes. Overexpression studies showed elevation in the levels of CO (2-fold) and CA (5-fold). Further, in infiltrated leaves levels of ferruginol (50%) and CA derivatives (rosmanol, epirosmanol, methyl carnosic acid) were significantly upregulated along with the other signature terpenes. Finally, stable transgenic lines of S. officinalis developed through Agrobacterium mediated in planta genetic transformation accumulated significant amounts of CO (4-folds), CA (3-folds) as compared to wild plants.

The stem parasitic plant Cuscuta campestris invades the host's stem with a specialized organ referred to as the haustorium, which absorbs nutrients and water from the host. Initiation of the parasitic process in C. campestris requires mechanical stimuli to its stem. However, the mechanisms by which C. campestris perceives mechanical stimuli are largely unknown. Previous studies have shown that mechanosensitive ion channels (MSCs) are involved in the perception of mechanical stimuli. To examine if MSCs are involved in prehaustorium development upon tactile stimuli, we treated C. campestris plants with an MSC inhibitor, GsMTx-4, which resulted in a reduced density of prehaustoria. To identify the specific MSC gene involved in prehaustorium development, we analyzed the known functions and expression patterns of Arabidopsis MSC genes and selected MID-1 COMPLEMENTING ACTIVITY 1 (MCA1) as a primary candidate. The MSC activity of CcMCA1 was confirmed by its ability to complement the phenotype of a yeast mid1 mutant. To evaluate the effect of CcMCA1 silencing on prehaustorium development, we performed host-induced gene silencing using Nicotiana tabacum plants that express an artificial microRNA (amiRNA) targeting CcMCA1. In the CcMCA1-silenced C. campestris, the number of prehaustoria per centimeter of stem length decreased, and the interval length between prehaustoria increased. Additionally, the expression levels of known genes involved in prehaustorium development, such as CcLBD25, decreased significantly in the CcMCA1-silenced plants. The results suggest that CcMCA1 is involved in prehaustorium development in C. campestris.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143010306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identifying useful mechanisms of salt tolerance is an important step towards development of salt-tolerant crops. Of particular interest are mechanisms that are present in wild crop relatives, as they may have greater stress tolerance than crop species. The coastal species Vigna marina is one of the promising plant resources for salt tolerance. V. luteola is another wild species with diverse habitats including seaside and riverbank, hereafter, V. luteola-beach and V. luteola-river, respectively. By comparative transcriptome and histological analyses, this study elucidated one important aspect of how V. marina achieves an extraordinary ability to suppress Na+ uptake. Under salt stress, V. marina specifically upregulated genes involved in Casparian strip formation and developed a multi-layered lignified apoplastic barrier around endodermis, whereas V. luteola-beach formed typical, band-like Casparian strips, and V. luteola-river formed only spot-like Casparian strips. As such, the ability of developing apoplastic barrier strongly correlated with those of suppressing Na+ uptake. The disruption of lignified barrier led to a dramatic increase of Na+ allocation to the shoot in V. marina, which was manifested in leaf etiolation and burning. Interestingly, despite the presence of reinforced apoplastic barrier, V. marina maintained transport of essential ions including K+, Mg2+, and Ca2+.

MYB transcription factors (TFs) are crucial for plant tolerance to abiotic stress. However, the roles and regulatory mechanism of MYB TFs underlying saline-alkaline stress tolerance has not yet been investigated in Betula platyphylla. In this report, BpMYB06, an R2R3-MYB TF, is induced in response to saline-alkaline stress in B. platyphylla. This protein functions as a nuclear-localized transcriptional activator. Both gain- and loss-of-function analyses indicate that the transcript level of BpMYB06 is positively correlated with saline-alkaline stress tolerance, primarily through the enhancement of reactive oxygen species scavenging and the regulation of osmotic and ionic balance. Additionally, BpMYB06 is implicated in the control of stomatal aperture. qRT-PCR results show that BpMYB06 regulates the expression of genes associated with stress tolerance. Furthermore, TF-centered Y1H and ChIP assays reveal that BpMYB06 binds to two novel core sequences ([A/C]CGG and TAG[C/A]), thereby inducing the expression of stress-related genes. Our findings provide new insights into the role of BpMYB06 in B. platyphylla under soda saline-alkaline stress and suggest that it could serve as a potential target gene for developing saline-alkaline stress-tolerant B. platyphylla plants.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142953955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although previous research has often focused on increasing the soybean isoflavone content because of the estrogen-like activity of dietary soy in humans, the rapidly increasing demand for soybean as a plant-based meat substitute has raised concerns about excessive isoflavone intake. Therefore, the production of isoflavone-free soybean has been anticipated. However, there have been no reports of an isoflavone-free soybean until now. Here, 2-hydroxyisoflavanone synthase (IFS), which is essential for isoflavone biosynthesis, was targeted for genome editing in soybean. A novel CRISPR/Cas9 system using Staphylococcus aureus Cas9 instead of the commonly-used Streptococcus pyogenes Cas9 was established and customized. Through Agrobacterium rhizogenes-mediated transformation, IFS-edited hairy roots were generated in which all three IFS genes contained deletion mutations. Metabolome analyses of IFS-edited hairy roots revealed that isoflavone content significantly decreased, whereas levels of flavonoids, including a novel chalcone derivative, increased. A transcriptome analysis revealed changes in the expression levels of a large number of genes, including jasmonic acid-inducible genes. In addition, the functions of selected transcription factor genes (MYB14-L, GmbHLH112, and GmbHLH113), which were dramatically upregulated by IFS editing, were investigated by multi-omics analyses of their over-expressing hairy root lines. They appear to be involved in flavonoid and triterpene saponin biosynthesis, salicylic acid metabolism, and central carbon metabolism. Overall, the results indicated that editing IFS genes caused the redirection of the metabolic flux from isoflavonoid biosynthesis to flavonoid accumulation, as well as dynamic changes in gene regulatory networks.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142953957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether all the fundamental properties of plasmodesmata emerged and were inherited in all land plants at the same time is unknown. Here we show that the bryophyte Marchantia polymorpha (a non-vascular plant) forms mostly simple plasmodesmata in early-developing gemmae. The complexity of plasmodesmata increases during gemma maturation, and complex plasmodesmata with enlarged cavities are majorly observed in thalli. In contrast to vascular plants, whose simple plasmodesmata can transport monomeric fluorescent proteins, plasmodesmata in Marchantia polymorpha limited their permeability before the juvenile-to-adult transition. In support, callose, a known polysaccharide regulating plasmodesmata permeability in vascular plants, accumulated in most of the Marchantia polymorpha tissues examined. Furthermore, we found that in the apical meristematic region, plasmodesmata allowed the transport of monomeric fluorescent proteins, and this relaxation might correlate with the lower accumulation of callose. Taken together, our study suggests that certain plasmodesmata properties, such as complexity progression and callose accumulation, may have evolved before the divergence between vascular and non-vascular plants.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142953956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
