However, the specific function of ABC transporters in plant antiviral defense remains poorly characterized. In this study, the homologous ABCI6 proteins originating from Citrus L. spp. showed high evolutionary conservation (higher than 75.82%). The expression of ClABCI6, the ABCI6 homologous gene in Eureka lemon (Citrus limon (L.) Osbeck), was significantly upregulated following infection with citrus yellow vein clearing virus (CYVCV). Further study showed that ClABCI6 localized specifically to the chloroplast and physically interacted with the RNA-dependent RNA polymerase domain (He-RdRp) of CYVCV using yeasts two-hybrid assays. In addition, ClABCI6 promoted the expression of He-RdRp and CYVCV, while concurrently suppressing the expression of salicylic acid (SA) pathway genes in lemon, thus facilitating viral proliferation. This study provides novel insights into the evolution and molecular function of ClABCI6, and reveals its response patterns to CYVCV-infection.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"655-665"},"PeriodicalIF":2.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147973243","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}

While solvent extraction provides precise chlorophyll measurements, it is destructive and temporally limited, whereas portable optical meters such as the CCM-300 enable rapid, non-destructive measurement of the chlorophyll fluorescence ratio (CFR) but require species- and season-specific calibration. This study evaluates the performance of CCM-300 measurements and reconstructs seasonal chlorophyll dynamics in field maple (Acer campestre) across two contrasting summers in the United Kingdom. Paired CFR and acetone-extracted chlorophyll data collected in 2023 were used to develop calibration models. RF regression achieved the highest predictive performance within the calibration dataset, although substantial uncertainty remained at the leaf level; a simple linear model was therefore adopted for cross-year projection due to its stability under extrapolation. Applying this calibration to daily 2022 CFR measurements generated a continuous \"virtual acetone\" trajectory, enabling qualitative comparison with weekly destructive extractions in 2023. Both years exhibited mid-season chlorophyll plateaus followed by late-summer declines; however, senescence, defined as the initiation of sustained post-peak decline, occurred earlier during the warmer and drier 2022 season. Mixed-effects modelling identified positive effects of temperature and wind speed on CFR in 2022, while generalised additive modelling of the 2023 dataset revealed a non-linear seasonal decline under comparatively mild conditions. Because cross-year projections rely on a low-fit linear calibration, interannual differences are interpreted primarily in terms of relative seasonal trajectory shape and timing rather than absolute chlorophyll magnitude.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"605-614"},"PeriodicalIF":2.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148252260","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}

In addition, nine known phenolic compounds were also isolated from the flowers of P. macrostachya. The pH values of P. macrostachya petals and sepals were 5.7 and 5.6, respectively. In vitro color reconstruction experiments using the two major anthocyanins from each organ, namely petreadelphin from the petals and delphinidin 3-O-(6-caffeoylglucoside)-5-O-glucoside from the sepals, showed that their absorption spectra closely match those of the corresponding floral tissues. These results indicate that each anthocyanin is primarily responsible for the coloration of its respective organ. Stability tests showed that the sepal anthocyanin faded rapidly after 15 min in the buffer solution, whereas petreadelphin retained its color for at least 24 h. This difference is likely due to the greater structural stability of petreadelphin conferred by its polyacylation. In addition, bee color vision modeling using the reflectance spectra indicated that the petals have significantly higher color intensity than sepals. These findings suggest that the type and number of acyl groups in anthocyanin may influence color intensity and potentially floral detectability by bees.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"667-679"},"PeriodicalIF":2.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148211774","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 integrated analyses identified three major lineages within the Japanese subg. Vetrix, revealed the polyphyly of the subg.

All orchids require mycorrhizal associations with specific fungi at the earliest stages of germination and development, and these symbioses may have played crucial roles in their adaptation to, and diversification within, canopy habitats. We present the first comprehensive comparison of fungal communities, encompassing both epiphytic and terrestrial orchids as well as their habitat substrates (bark and soil) on Yakushima Island, Japan. We analyzed mycorrhizal communities associated with 29 orchid species, representing eight tribes in four subfamilies, using both Sanger and high-throughput sequencing (HTS) methods, and also characterized fungal communities in the substrates using HTS. Our results reveal that epiphytic and terrestrial orchids have differing mycorrhizal communities and the fungal composition of their habitat substrates also differs. Although overall fungal richness was lower in epiphytic than in terrestrial substrates, the diversity of fungi in the rhizoctonia, including members of Tulasnellaceae, Ceratobasidiaceae, and Serendipitaceae, was similarly high for both habitat types. Furthermore, some rhizoctonia fungi were shared between orchid life forms and exhibited symbiotic compatibility across habitats in in vitro culture. Although rhizoctonia communities differed between habitat substrates, comparable diversity and the presence of shared taxa across habitats imply that these fungi may have reduced barriers to canopy colonization and contribute to the successful establishment and diversification of epiphytic orchids.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"559-573"},"PeriodicalIF":2.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147930439","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 Korean east coast, and the volcanic island of Ulleungdo facing it, is a region where species populations and lineages are allopatrically distributed, including those of the seashore spatulate aster (Aster spathulifolius Maxim.). In this study, we examined the disjunct distribution of this coastal specialist by employing genome-wide SNP markers to evaluate its genomic diversity and structure, and infer its number of independently evolving lineages in this region. Our findings suggest that the genetically distinct population structure between the peninsular and island distributions, and the significantly reduced genetic variation patterns, more so for the insular populations, appeared to be the classic signatures of the mainland-island model. The vicariant population distribution was further found to be delineated by a genetic barrier, i.e., the East Sea geographic break, although isolation by distance may have also influenced the divide. Along with the molecular line of evidence, the nomenclatural and taxonomic implications of the findings are also discussed in this paper.","PeriodicalId":16813,"journal":{"name":"Journal of Plant Research","volume":" ","pages":"545-558"},"PeriodicalIF":2.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147930594","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}
