The regeneration potential, biomass production, and seed yield of perennial forage species are highly reliant on the development of tillering. Strigolactones (SLs) are recently discovered carotenoid-derived phytohormones that play a crucial role in the regulation of tillering in annual crops. However, the modulation of tiller growth in perennial forage by SLs remains insufficiently investigated. In this study, we identified two alleles of the SLs biosynthesis gene, DgCCD7A and DgCCD7D, which encode CAROTENOID CLEAVAGE DIOXYGENASE 7 (CCD7), from two distinct subspecies of orchardgrass (Dactylis glomerata) exhibiting contrasting tillering phenotype and SLs content. The functionality of the DgCCD7A allele derived from high-tillering phenotypic orchardgrass was found to be diminished compared to that of DgCCD7D from the low-tillering type in rescuing the increased branching phenotype of CCD7-defective mutants in Arabidopsis and rice (Oryza sativa). Notably, the introduction of DgCCD7A in rice resulted in an increase in tiller number without significantly compromising grain yield. Moreover, we demonstrated that the L309P variation in DgCCD7A is a rare natural variant exclusively found in orchardgrass. Our findings revealed that DgCCD7A, a rare favorable natural variation of CCD7 in orchardgrass, holds significant potential for breeding application in improving the plant architecture of perennial forage and crops.","PeriodicalId":233,"journal":{"name":"The Plant Journal","volume":" ","pages":""},"PeriodicalIF":6.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better understand the evolution of VDT, we generated chromosome-level assemblies and improved genome annotations of two Selaginella species with contrasting abilities to survive desiccation. We identified genomic features and critical mechanisms associated with VDT through sister-group comparative genomics integrating multi-omics data. Our findings indicate that Selaginella evolved VDT through the expansion of some stress protection-related gene families and the contraction of senescence-related genes. Comparative analyses revealed that desiccation-tolerant Selaginella species employ a combination of constitutive and inducible protection mechanisms to survive desiccation. We show that transcriptional priming of stress tolerance-related genes and accumulation of flavonoids in unstressed plants are hallmarks of VDT in Selaginella. During water loss, the resurrection Selaginella induces phospholipids and glutathione metabolism, responses that are missing in the desiccation-sensitive species. Additionally, gene regulatory network analyses indicate the suppression of growth processes as a major component of VDT. This study presents novel perspectives on how gene dosage impacts crucial protective mechanisms and the regulation of central processes to survive extreme dehydration.","PeriodicalId":233,"journal":{"name":"The Plant Journal","volume":" ","pages":""},"PeriodicalIF":6.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With this release, we also make the underlying \"Genome Zoo\" available, a curated protein data set with scripts and metadata. Eighteen new TAP (sub)families were added as part of the update. Nine of those were gained in the most recent common ancestor of the Streptophyta (comprising streptophyte algae and land plants), or within the streptophyte algae. More than one-third of all detected TAP family gains were identified during the evolution of streptophyte algae, before the emergence of land plants, and are thus likely to have been significant for plant terrestrialization. The TAP complement of the Zygnematophyceae was identified to be the most similar to that of land plants, consistent with the finding that this lineage is sister to land plants. Overall, our data retrace the evolution of streptophyte TAPs, allowing us to pinpoint the regulatory repertoire of the earliest land plants.","PeriodicalId":233,"journal":{"name":"The Plant Journal","volume":" ","pages":""},"PeriodicalIF":6.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leaf angle, an important agronomic trait relevant to planting density, plays a fundamental role in light penetration into the canopy and photosynthetic efficiency. Leaf angle is a key parameter of plant architecture in the concept of smart canopy. Maize smart-canopy-like plant architecture exhibits optimal leaf angle, resulting in erect upper leaves and intermediate or horizontal lower leaves. Leaf angle regulation is a promising way forward in the breeding of varieties with canopy ideotypes. In this review, we first describe the relationship between maize polarity axes and leaf angle formation. Then, we revisit advances in the mutant and quantitative genetics research of maize leaf angle, highlighting the biological implications of transcription factors for maize leaf angle regulation. We underscore that KNOX family is essential for the blade-sheath boundary establishment and brassinosteroid pathway components as well as regulator ZmRAVL1 serve as key hubs of the transcriptional hierarchy governing maize leaf angle formation. We also suggest potential avenues for manipulating maize leaf angles across canopy layers.","PeriodicalId":233,"journal":{"name":"The Plant Journal","volume":" ","pages":""},"PeriodicalIF":6.2,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142811547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plants lacking the PSK receptors show phenotypes consistent with PSK signaling repressing some plant defenses. To gain further insight into the PSK signaling mechanism, comprehensive transcriptional profiling of Arabidopsis treated with PSK was performed, and the effects of PSK treatment on plant defense readouts were monitored. Our study indicates that PSK's major effect is to downregulate defense-related genes; it has a more modest effect on the induction of growth-related genes. WRKY transcription factors (TFs) emerged as key regulators of PSK-responsive genes, sharing commonality with a pathogen-associated molecular pattern (PAMP) responses, flagellin 22 (flg22), but exhibiting opposite regulatory directions. These PSK-induced transcriptional changes were accompanied by biochemical and physiological changes that reduced PAMP responses, notably mitogen-activated protein kinase (MPK) phosphorylation (previously implicated in WRKY activation) and the cell wall modification of callose deposition. Comparison with previous studies using other growth stimuli (the sulfated plant peptide containing sulfated tyrosine [PSY] and Pseudomonas simiae strain WCS417) also reveals WRKY TFs' overrepresentations in these pathways, suggesting a possible shared mechanism involving WRKY TFs for plant growth–defense trade-off.","PeriodicalId":233,"journal":{"name":"The Plant Journal","volume":"120 6","pages":"2367-2384"},"PeriodicalIF":6.2,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/tpj.17115","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142811555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this bottleneck, plant RNA viruses have been deployed as versatile tools for in planta delivery of recombinant RNA. Viral delivery of single-guide RNAs (sgRNAs) to transgenic plants that stably express CRISPR-associated (Cas) endonuclease has been successfully used for targeted mutagenesis in several dicotyledonous and few monocotyledonous plants. Progress with this approach in monocotyledonous plants is limited so far by the availability of effective viral vectors. We engineered a set of foxtail mosaic virus (FoMV) and barley stripe mosaic virus (BSMV) vectors to deliver the fluorescent protein AmCyan to track viral infection and movement in Sorghum bicolor. We further used these viruses to deliver and express sgRNAs to Cas9 and Green Fluorescent Protein (GFP) expressing transgenic sorghum lines, targeting Phytoene desaturase (PDS), Magnesium-chelatase subunit I (MgCh), 4-hydroxy-3-methylbut-2-enyl diphosphate reductase, orthologs of maize Lemon white1 (Lw1) or GFP. The recombinant BSMV did neither infect sorghum nor deliver or express AmCyan and sgRNAs. In contrast, the recombinant FoMV systemically spread throughout sorghum plants and induced somatic mutations with frequencies reaching up to 60%.

As a perennial foliage crop, tea plants have high-nitrogen consumption and demand but exhibit relatively low nitrogen use efficiency. Exploring the genetic factors involved in nitrogen assimilation in tea plants could lead to improvements in both tea yield and quality. Here, we first conducted transcriptome sequencing on two tissues (roots and young leaves) under two different nitrate levels (0.2 and 2.5 mm KNO3) and at six time points (0, 15, and 45 min; 2 and 6 h and 2 days). Differential gene expression patterns were observed for several genes that exhibited altered expression at 2 h. Clustering and enrichment analyses, along with co-expression network construction, provided evidence for the crucial involvement of CsSNACA2 in nitrogen assimilation. CsSNACA2 overexpression elicited pronounced phenotypic changes in nitrogen-deficient plants. Furthermore, CsSNACA2 suppressed the expression of CsNR (encoding nitrate reductase) and CsCLCa (encoding a <math> <semantics> <mrow><msubsup><mi>NO</mi> <mn>3</mn> <mo>-</mo></msubsup> </mrow> <annotation>$$ {mathrm{NO}}_3^{-} $$</annotation></semantics> </math> /H+ exchanger).

This study identified a transcription factor module participating in nitrogen assimilation in tea plants, providing a genetic foundation for future innovations in tea cultivar improvement.

Fusarium solani is the primary pathogen responsible for apple replant disease. In this study, we identified an MYB protein, MdMYB54, which interacts with the positive regulator of F. solani resistance, MdERF114, and confers apple-increased tolerance against F. solani. The cellulose synthetase (CESA) gene MdCesA6 and pectin lyase-like (PLL) genes MdPLL8 and MdPLL12 were screened as three potential downstream target genes of MdMYB54 using DAP-seq. The results of electrophoretic mobility shift and yeast one-hybrid assays showed that MdMYB54 directly binds to the promoters of MdCesA6, MdPLL8, and MdPLL12 in vivo and in vitro. Dual-luciferase and β-glucuronidase assays showed that MdMYB54 activates the expression of these genes. The cellulose content and pectin lyase activity of MdMYB54-overexpressed roots were significantly higher than those of wild-type plants under F. solani treatment but were the opposite in MdMYB54-RNAi roots. The deposition of cellulose enhanced the physical barrier of the plant cell wall, whereas the activation of pectin lyase promoted the formation of oligogalacturonides and the production of reactive oxygen species. Overexpression of MdCesA6, MdPLL8, and MdPLL12 in the root system enhanced the tolerance of apple to F. solani. The direct interaction of MdERF114 with MdMYB54 enhanced MdMYB54-mediated cell wall defense response.
