This study compared the de-etiolation process under monochromatic red or blue light of equal photon flux density during a 24-h illumination period of etiolated Arabidopsis seedlings. The aim was to elucidate the impact of these light wavelengths on the etioplast-to-chloroplast transformation and the initiation of light-dependent photosynthetic reactions. Both treatments led to the formation of functional young chloroplasts; however, the etioplast-to-chloroplast transition and the assembly of photosynthetic complexes occurred unevenly, with individual steps tuned by red or blue light. Ultrastructural analysis suggested faster prolamellar body's disassembly under blue light, while low-temperature fluorescence studies indicated a slower transformation of protochlorophyllide to chlorophyllide, and chlorophyll a, under these conditions. The red light further promoted the synthesis of chlorophyll b and LHCII antenna proteins. However, the efficiency of antennae in dissipating excess absorbed energy was higher for seedlings de-etiolated under blue light; the maximum quantum yield of the photosystem II reached 0.81 after 24-h de-etiolation, equivalent to mature plants. Blue light seemed to enhance the development of well-functioning photosystems (I and II) and antennae. These findings are important for gaining a deeper understanding of photoreceptor regulation of de-etiolation and for utilizing selected light regimes to improve crop yield.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":"1993-2017"},"PeriodicalIF":3.9,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11662447/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142406804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This mini-review highlights the intricate phosphate and iron uptake and homeostasis processes taking place in legumes during their interactions with rhizobia. The coordination of transport and homeostasis of these nutrients in host plants and rhizobia ensures an efficient nitrogen fixation process and nutrient use. We discuss the genetic machinery controlling the uptake and homeostasis of these nutrients in the absence of rhizobia and under symbiotic conditions with this soil bacterium. We also highlight the genetic impact of the availability of phosphate and iron to coordinate the activation of the genetic programs that allow legumes to engage in symbiosis with rhizobia. Finally, we discuss how the transcription factor phosphate starvation response might be a crucial genetic element to integrate the plant's needs of nitrogen, iron and phosphate while interacting with rhizobia. Understanding the coordination of the iron and phosphate uptake and homeostasis can lead us to better harness the ecological benefits of the legume-rhizobia symbiosis, even under adverse environmental conditions.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":"1925-1936"},"PeriodicalIF":3.9,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11662446/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142506576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the combustion process, ash-containing silicon (Si) can be produced, which causes problems in furnace maintenance. Hence, lowering Si content in plants is crucial. However, limiting Si supply to crops is difficult in practice because Si is abundant in the soil. Previously, an Si uptake transporter (SbLsi1) has been identified, and an Si-depleted mutant has also been generated in the model sorghum variety BTx623. In this study, we aimed to investigate the changes induced by a mutation in SbLsi1 on the accumulation and structure of lignin in cell walls. Through chemical and NMR analyses, we demonstrated that the lsi1 mutation resulted in a significant increase in lignin accumulation levels as well as a significant reduction in Si content. At least some of the modification was induced by transcriptional changes, as suggested by the upregulation of phenylpropanoid biosynthesis-related genes in the mutant plants. These findings derived from the model variety could be useful for the future development of practical cultivars with high biomass and less Si content for bioenergy applications.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":"1983-1992"},"PeriodicalIF":3.9,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142352644","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 barley, the predominant cultivars possess long awns that contribute to grain yield and quality through photosynthesis. Barley is a useful cereal crop to investigate the mechanism of awn development as various awn morphological mutants are available. Here, we identified the gene causative of the short and crooked awn (sca) mutant, which exhibits a short and curved awn phenotype. Intercrossing experiments revealed that the sca mutant induced in the Japanese cultivar (cv.) 'Akashinriki' is allelic to independently isolated moderately short-awn mutant breviaristatum-a (ari-a). Map-based cloning and sequencing revealed that SCA encodes the Polycomb group-associated protein EMBRYONIC FLOWER 1 (EMF1). We found that SCA affects awn development through the promotion of cell proliferation, elongation, and cell wall synthesis. RNA sequencing of cv. Bowman (BW) backcross-derived near-isogenic lines of sca and ari-a6 alleles showed that SCA is directly or indirectly involved in promoting the expression of genes related to awn development. Additionally, SCA represses various transcription factors essential for floral organ development and plant architecture, such as MADS-box and KNOX1 genes. Notably, the repression of the C-class MADS-box gene HvMADS58 by SCA in awns is associated with the accumulation of the repressive histone modification H3K27me3. These findings highlight the potential role of SCA-mediated gene regulation, including histone modification, as a novel pathway in barley awn development.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142865186","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}

Simultaneously, various environmental stressors, such as high/low temperatures and high light intensity, affect plant photosynthesis in the leaves. However, the combined effects of iron nutrient conditions and abiotic stresses have not yet been clarified. In this study, we analyzed how iron nutrition conditions impact the chilling-induced damage on cucumber leaves (Cucumis sativus L.). When cucumbers were grown under different iron conditions and then exposed to chilling stress, plants grown under a high iron condition exhibited more severe chilling-induced damage than the control plants. Conversely, plants grown under a low-iron condition showed an alleviation of the chilling-induced damages. These differences were observed in a light-dependent manner, indicating that iron intensified the toxicity of reactive oxygen species generated by photosynthetic electron transport. In fact, plants grown under the low-iron condition showed less accumulation of malondialdehyde derived from lipid peroxidation after chilling stress. Notably, the plants grown under the high iron condition displayed a significant accumulation of iron and an increase in lipid peroxidation in the shoot, specifically after light-chilling stress, but not after dark-chilling stress. This indicated that increased root-to-shoot iron translocation, driven by light and low temperature, exacerbated leaf oxidative damage during chilling stress. These findings also highlight the importance of managing iron nutrition in the face of chilling stress and will facilitate crop breeding and cultivation strategies.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":"1873-1887"},"PeriodicalIF":3.9,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142352646","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 shoot branching involves two main processes: axillary meristem formation and subsequent bud outgrowth. While considerable progress has been made in elucidating the genetic mechanisms underlying the latter process, our understanding of the former process remains limited. Rice FINE CULM1 (FC1), which is an ortholog of teosinte branched1 in maize (Zea mays) and BRANCHED1/2 in Arabidopsis (Arabidopsis thaliana), is known to act in the latter process by repressing bud outgrowth. In this study, we found that FC1 also plays a role in the former process, i.e. axillary meristem formation, in rice. This study was triggered by our unexpected observation that fc1 mutation suppresses the loss of axillary meristems in the loss-of-function mutant of the rice WUSCHEL gene TILLERS ABSENT1 (TAB1). In tab1 fc1, unlike in tab1, both stem cells and undifferentiated cells were maintained during axillary meristem formation, similar to the wild type. Morphological analysis showed that axillary meristem formation was accelerated in fc1, compared to the wild type. Consistent with this, cell proliferation was more active in the region containing stem cells and undifferentiated cells during axillary meristem formation in fc1 than in the wild type. Taken altogether, these findings suggest that FC1 negatively regulates axillary meristem formation by mildly repressing cell proliferation during this process.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":"1862-1872"},"PeriodicalIF":3.9,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142473129","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 blue light receptor phototropin regulates the chloroplast movement in various plant species. In Arabidopsis thaliana, phototropin mediates the light-induced chloroplast movement and positioning via specialized actin filaments on the chloroplasts, chloroplast-actin filaments. KINESIN-LIKE PROTEIN FOR ACTIN-BASED CHLOROPLAST MOVEMENT (KAC) and CHLOROPLAST UNUSUAL POSITIONING 1 (CHUP1) are pivotal for actin-based chloroplast movement and positioning in land plants. However, the mechanisms by which KAC and CHUP1 regulate chloroplast movement and positioning remain unclear. In this study, we characterized KAC and CHUP1 orthologs in the liverwort Marchantia polymorpha, MpKAC and MpCHUP1, respectively. Their knockout mutants, Mpkacko and Mpchup1ko, impaired the light-induced chloroplast movement. Although Mpchup1ko showed mild chloroplast aggregation, Mpkacko displayed severe chloroplast aggregation, suggesting the greater contribution of MpKAC to the chloroplast anchorage to the plasma membrane. Analysis of the subcellular localization of the functional MpKAC-Citrine indicated that MpKAC-Citrine formed a punctate structure on the plasma membrane. Structure-function analysis of MpKAC revealed that the deletion of the conserved C-terminal domain abrogates its targeting to the plasma membrane and its function. The deletion of the N-terminal motor domain retains the plasma membrane targeting but abrogates the formation of punctate structure and shows a severe defect in the light-induced chloroplast movement. Our findings suggest that the formation of the punctate structure on the plasma membrane of MpKAC is essential for chloroplast movement.","PeriodicalId":20575,"journal":{"name":"Plant and Cell Physiology","volume":" ","pages":"1787-1800"},"PeriodicalIF":3.9,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142111312","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}
