This study evaluated the richness, abundance, and co-occurrence in the gall community associated with Caryocar brasiliense Cambess. (Caryocaraceae) areas with varying degrees of environmental stress due to the drying of palm swamps, called Veredas. Additionally, structural and metabolic attributes related to nutrition and protection were evaluated as possible stress markers. The research was conducted in two Cerrado areas with different water availability: the Parque Estadual Veredas do Peruaçu (lower water availability; more stressful) and the Área de Proteção Ambiental do Rio Pandeiros (higher water availability; less stressful). A total of 51,336 galls from five morphospecies were sampled: intralaminar globoid gall (IGG), extralaminar globoid gall (EGG), globoid petiolar gall (GPG), lenticular gall (LG) and clavate gall (CG). Gall richness was similar in both environments, but abundance was higher in the less stressful area, challenging the hypothesis that environmental stress increases gall formation. Random co-occurrence patterns suggested that gall inducers occupy distinct spatial niches to reduce competition. Structurally and metabolically, galls exhibited similarities, including nutritive tissues and nutritious substances in their internal compartments. However, in the more stressful environment, some galls had smaller internal and larger external compartments, with increased lignin and phenolic compounds in the outer tissue layers. Lignin deposition and phenolic accumulation are evidenced as stress markers which indicate that galls display phenotypic plasticity and adaptive strategies, enhancing protection and survival under the stressful conditions of drying environments.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787439","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}

Merremia platyphylla (Convolvulaceae) exhibits floral traits typical of bat pollination (i.e., chiropterophily), including white bell-shaped flowers with crepuscular anthesis and abundant nectar production. These traits suggest that bats are likely the most important pollinators for this species. We investigated the nectar traits, volatile organic compounds, and the pollination and mating system of M. platyphylla to assess whether its floral characteristics align with the chiropterophily syndrome and determine if bats are the most effective pollinator. Although peak nectar production and volatile compounds did not entirely match those expected for bat-pollinated plants, M. platyphylla was effectively pollinated by bats, followed by diurnal pollinators, likely hummingbirds, but not honeybees, since they did not contribute to fruit production. This study provides the first record of bat pollination and floral volatile compounds not only in the genus Merremia, but also in the entire tribe Merremieae. We discuss whether this species is in a stable mixed pollination state or undergoing a transitional phase toward specialized bat pollination, given its generalized pollination system and the mismatch between some floral traits and those typically seen in chiropterophilous plants.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778637","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 basis of the association between flower polymorphism and deceptive strategies, however, remains unclear. Epidendrum fulgens, a Neotropical deceptive orchid pollinated by butterflies, has an unexplored intrapopulation flower colour polymorphism. Here, we investigate the consequences of this polymorphism on its reproductive success. We performed field and common garden experiments, aiming to detect pollinator-mediated selection strength and direction over time, and test whether the presence of multiple colour morphs increases species' reproductive success. In the field, we monitored plant reproductive success and floral morphology on two populations over two flowering seasons and performed selection gradient analyses. In the common garden, we assembled plots of cultivated plants with same and different flower colour individuals (i.e., mono- and polymorphic plots), exposed them to pollinators and monitored their reproductive success. In both sites we also monitored the local pollinator community. In the field, colour morphs performed equally, but we found coherences between morphological differentiation and the direction of selection, which was very dynamic. In the common garden, mono- and polymorphic plots also performed equally, with highly variable reproductive success over time. We also found a highly diverse pollinator community. Our results suggest that flower polymorphism in E. fulgens is maintained by a combination of factors, including varying pollinator-mediated selection, assortative mating due to differential pollinator preferences and different phenotype heritability. Natural selection varied across time and space, indicating a dynamic interplay between pollinators and flower morphs.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750381","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}

As benzoxazinoids are suggested to play a role in resistance against these stressors, and in allelopathy, we also aimed to identify compounds in root exudates. We conducted in vitro and glasshouse bioassays to determine the efficacy of a wide range of crude cereal root exudates and their constituent compounds in inhibiting black-grass in both axenic and biologically-active media. LC-MS analysis was used to characterise constituents of these exudates and differences between hexaploid wheat, diploid wheat and rye. Root development of black-grass was suppressed to various degrees by crude root exudates from these cereals, with the most effective being S. cereale var. Edmondo and T. monococcum MDR037. Benzoxazinoid content of root exudates varied, with ancestral wheat lines and rye exuding fewer of these compounds than hexaploid wheat, but with higher variability between lines. Co-culture with T. aestivum var. Gravity significantly inhibited early shoot growth and biomass of black-grass seedlings, but individual benzoxazinoids had no effect on black-grass in the same system. These data provide evidence that cereal-black-grass interactions are influenced by root exudates, but that their effects cannot be replicated through direct application of individual constituent compounds.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707949","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 the orchid genus Vanilla, seed dispersal is mediated by vertebrates. Although primates have never been observed consuming vanilla pods under experimental conditions, monkeys have been proposed as possible seed dispersers of Vanilla in Central Brazil. Here, I investigate mechanisms involved in the attraction and rewarding of seed dispersers of a Neotropical Vanilla based on field observations, morpho-anatomy of fruits and seeds, analysis of fragrances, reward substances, and examination of seed viability through the digestive tract. In addition, an experiment has been conducted to examine whether fruit consumption in Vanilla may involve some kind of social learning. Dehiscent fruits of V. pompona are consumed by mammals: monkeys, rats, and marsupials. Besides providing nutritive rewards in the placenta and funiculus, the fruit wall is rich in calcium oxalate crystals, which are toxic to mammals. Consequently, seed dispersers access the fruit cavity through the fruit valves. While primates are the main seed dispersers in natural populations, no monkeys consume fruits outside the Vanilla habitat. Vanilla fruits are consumed by both diurnal and nocturnal mammals, evidencing the importance of both visual and olfactory cues in the attraction of seed dispersers. Unrecognized or harmful fruits seem to be a poor choice for consumption in resource-rich environments. Monkeys require a period of resource scarcity to be stimulated and learn how to safely consume Vanilla fruits. After incorporating such fruits into the diet of knowledgeable individuals, the information is transmitted to naïve individuals through social learning. This is the first study to describe monkeys as seed dispersers in orchids.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699274","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}

A crucial step in understanding the origin of such chemodiversity is describing how chemodiversity manifests across the spatial and ontogenetic scales relevant to plant-biotic interactions. Focusing on 21 sympatric species of Psychotria and Palicourea sensu lato (Rubiaceae), we describe patterns of specialized metabolite diversity across spatial and ontogenetic scales using a combination of field collections, untargeted metabolomics, and ecoinformatics. We compare α, β, and γ diversity of specialized metabolites in expanding leaves, unripe pulp, immature seed, ripe pulp, mature seed, and fine roots. Within species, fruit tissues from across ontogenetic stages had ≥α diversity than leaves, and ≤β diversity than leaves. Pooled across species, fruit tissues and ontogenetic stages had the highest γ diversity of all organs, and fruit tissues and ontogenetic stages combined had a higher incidence of organ-specific mass spectral features than leaves. Roots had ≤α diversity than leaves and the lowest β and γ diversity of all organs. Phylogenetic correlations of chemical distance varied by plant organ and chemical class. Our results describe patterns of specialized metabolite diversity across organs and species and provide support for organ-specific contributions to plant chemodiversity. This study contributes to the growing understanding within plant evolutionary ecology of the biological scales of specialized metabolite diversification. Future studies combining our data on specialized metabolite diversity with biotic interaction data and experiments can test existing hypotheses on the roles of ecological interactions in the evolution of chemodiversity.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690424","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}

Like visual signals, the scents emitted by flowers can be associated with the attraction of specific pollinator classes. As such, divergence in floral scent composition can be a key isolation mechanism for speciation. Between continents, the leafy vegetable Gynandropsis gynandra possesses differences in morphology, phenology, foliar chemodiversity, and pollinators. Importantly, G. gynandra is pollinated by hawkmoths in Africa, and bees and butterflies in Asia. Here, we combined chemical, morphological, and transcriptome analyses to assess differences in the floral scent and scent-releasing structures between African and Asian G. gynandra accessions, and within flowers of the same accession. The prevalence of nitriles and benzenoids in the floral fragrance of the African and Asian accessions, respectively, corresponds to features typically associated with their differing pollinator classes. Further, we uncovered differences in floral epidermal cell morphology, with papillae present on the petal claws and nectary of the African accession and absent (or reduced) for the Asian accession. Through transcriptomic analyses, we showed that the stalk-like floral structures are putatively involved in terpenoid biosynthesis and emission. However, the epidermal cell morphology and staining suggests that the petals, stamens, and stigma may be involved in scent production of other floral volatile classes (e.g., nitrogen-containing compounds). These additional phytochemical and morphological distinctions between African and Asian accessions suggest that the divergent forms of G. gynandra may merit taxonomic recognition at subspecies level.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661820","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}

These changes may also affect the pollinator community, reproductive success, and, potentially, the characteristics of progeny. However, anthropogenic increases in the frequency of fires could reverse the beneficial effects of fire. We evaluate the effect of fire frequency on sexual expression, pollination, female reproductive success, and early progeny vigour of Solanum palinacanthum, an andromonoecious resprouting herb in South American Chaco ecosystems. Measurements were performed at six sites along a gradient of fire frequency, ranging from 0 to 5 fires over 22 years. We found that plant size and the proportion of hermaphrodite (relative to male) flowers increased at intermediate fire frequency sites (twice burned) compared to unburned sites, but both declined at high-fire frequency sites. Pollinator visits were also more frequent in plants from the area with intermediate fire frequency. Although fire frequency did not enhance the probability of fruit set, it increased total fruit number in plants from the site burned twice. Seeds from sites with intermediate fire frequency had both higher mass and germination rates. Soil resources and maternal environmental effects shaped by fire frequency play a key role in the sexual reproduction and early progeny vigour of S. palinacanthum. Nonetheless, increased fire frequency due to human activities may override the beneficial effects of fire on plant reproduction.","PeriodicalId":220,"journal":{"name":"Plant Biology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646702","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}
