It is considered that cell wall thickness (TCW) affects diffusion and leakiness of CO2 within leaves, but it is unclear whether TCW of photosynthetic cells differs among these groups. This study investigated TCW of photosynthetic cells in herbaceous C3, C4, and CAM species under an electron microscope. Among 75 species of monocots and eudicots grown in a growth chamber in the same environment, the TCW of mesophyll cells (MCs) was much higher in CAM species than in C3 and C4 species. However, when TCW was compared between C3 and C4 species of grasses and eudicots, TCW of MCs tended to be lower in C4 species than in C3 species; the opposite trend was observed for TCW of bundle sheath cells (BSCs). TCW of MCs and BSCs almost did not differ among the C4 decarboxylation types (NADP-ME, NAD-ME, and PCK). In plants grown outdoors (51 species), similar trends of TCW were also found among photosynthetic groups, but their TCW was generally higher than that of growth-chamber plants. This study provides the TCW spectrum of photosynthetic cells in herbaceous C3, C4, and CAM species. The results obtained would be valuable for our understanding of the diffusion and leakage of CO2 in the leaves of different photosynthetic groups.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"197-213"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, various populations respond differently to elevated nitrogen levels. This study explores the responses of central and edge populations of the annual invasive plant Galinsoga quadriradiata to different levels of nitrogen addition. The results indicate that the central population has a stronger need for nitrogen, with nitrogen addition promoting the growth of its aboveground parts, reducing intraspecific competition, and increasing reproductive allocation and total biomass. Specifically, nitrogen addition provides more nutritional resources, easing resource competition among plants, reducing intraspecific competitive pressure, and allowing plants to allocate more energy to growth and reproduction, thereby enhancing their expansion potential. In contrast, the edge populations respond differently to nitrogen. Although nitrogen addition promotes the growth of their underground parts and enhances root development, the impact on aboveground parts is smaller. The enhancement of underground parts helps edge populations better adapt to barren environments, improving their survival and competitive ability in new environments, thus increasing their expansion potential. Overall, the growth impact on edge populations due to nitrogen addition is smaller, possibly indicating they have exceeded their nitrogen limit. The study demonstrates that the degree of population differentiation in invasive plants at different invasion stages is a critical factor in studying their spread potential, aiding in predicting plant invasion trends under climate change and providing theoretical support for formulating targeted management strategies.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"243-251"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143189080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Ppd-1 genes play a crucial role in determining wheat sensitivity to changes in day-length and serve as key regulators of heading dates once the vernalization requirement is satisfied. In this study, we identified a new allelic variant of the promoter region, Ppd-B1a.3, in the Chinese wheat cultivar Qingchun 37. Compared to the Ppd-B1b.1 (carried by Chihokukomugi), the main mutation sites in Ppd-B1a.3 include a substitution of C with G at the -505-bp, a T base insertion at the -625-bp, a mutation of TCG to GGT at the -632 to -634-bp, and a 163-bp insertion at the -691 bp. Analysis of F2 populations indicated that Ppd-B1a.3 promotes heading and flowering (approximately 6 days earlier in population 1 and 17 days in population 2) under short-day conditions in a greenhouse. However, the evaluation of Ppd-B1a.3's effect under field conditions may be influenced by the copy number of the Ppd-B1 locus inherited from the other parent in the F2 populations. Ppd-B1a.3 disrupts circadian rhythm expression and exhibits a stronger effect on heading and flowering than the three-copy Ppd-B1 allele carried by Jing 411. Origin analysis suggests that Ppd-B1a.3 may have derived from non-native germplasm. These results deepen our understanding of wheat photoperiod genes and provide useful genetic resources for fine-tuning wheat heading dates during breeding.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"273-287"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142909804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two thioredoxin (Trx)-like proteins [atypical Cys His-rich Trx (ACHT) and Trx-like2 (TrxL2)] have been identified as crucial for oxidizing and deactivating several chloroplast enzymes during light-to-dark transitions; however, their roles remain to be fully understood. In this study, we investigated the functions of Trx-like proteins in seed development. Using the CRISPR/Cas9 system, we generated an Arabidopsis quadruple mutant defective in ACHT1, ACHT2, TrxL2.1, and TrxL2.2 (acht/trxl2). This mutant showed increased seed lethality prior to maturation, with embryogenesis impaired primarily during the heart and torpedo stages, which are critical phases for plastid differentiation into chloroplasts. Using transgenic plants expressing EGFP-fused proteins, we confirmed that ACHT and TrxL2 are localized in plastids during embryogenesis. Additionally, seed development in the acht/trxl2 mutant was further impaired under extended darkness and could not be recovered through complementation with variants of ACHT or TrxL2 lacking the redox-active Cys residue (replaced by Ser). These findings indicate that the protein-oxidation functions of ACHT and TrxL2 are important for plastid differentiation into chloroplasts, embryogenesis, and seed development.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"337-345"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11910432/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142872396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This axis can be considered as an articulated pedicel, peduncle, peduncle-pedicel, or anthopodium. Such disparity in terminology reveals a duality in interpretation since this structure is classified as part of the inflorescence or part of the flower. In an effort to reach a consensus, this study aims to evaluate axes supporting the flowers of species from the Malveae tribe through ontogenetic, morphological, and histochemical analyses, using light microscopy and scanning electron microscopy. Ontogenetic analyses indicated that the axis supporting the flower is an articulated pedicel, which is divided into proximal and distal parts owing to the presence of the constriction (joint). Simultaneously, the articulated pedicel arises from the floral meristem, along with the establishment of the calyx and androecium. As development progresses, we observed frequent abscissions of the floral bud, along with the distal portion of the pedicel, at the joint. After this, the remaining proximal portion of the pedicel becomes secretory, as an extrafloral nectary, often foraged by ants of the genus Wasmannia. Thus, this ontogenetic analysis of the articulated pedicel helps in understanding its functionality and morphological variability, highlighting the importance of standardized terminology since it would lead to conceptual clarity in different studies. Additionally, this study, for the first time, reveals the presence of extrafloral nectaries on articulated pedicels in Malveae, a previously undocumented feature in Malveae and Malvaceae.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"65-76"},"PeriodicalIF":2.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142622665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
