This study aimed to determine the presence and concentration of Al and other reserve components in Q. grandiflora seeds, as well as their respective distribution patterns, mobilization, and usage during germination and seedling growth. Thus, the concentration of Al and other minerals in seeds, seedlings, and soils was measured. Also, histochemical and energy‐dispersive X‐ray spectroscopy (EDS) analyses were performed to observe the distribution of Al, proteins, and lipids in Q. grandiflora seeds and seedlings. Additionally, the concentration of proteins and lipids was assessed as well. Hence, even in soils with low exchangeable Al3+, Q. grandiflora seeds accumulated about 6.43 g of Al/kg of dry matter (DM) together with considerable concentrations of N, P, K, Ca, and Mg. Exogenous Al had no effect on the germination properties of Q. grandiflora seeds. Furthermore, approximately 60% of the seed Al was translocated to seedling leaves. Proteins and lipids were the main organic reserves in Q. grandiflora seeds. The histochemical analysis revealed that the bulk of Al in seeds was in the cotyledons, which were also the location sites of proteins and lipids. Proteins and lipids were the primary source of energy and carbon for seedling growth. Therefore, fatty acids, proteins, and Al could play a central role during seed germination and seedling establishment, which could help to explain why this species is one of the most widespread plants in the Cerrado.","PeriodicalId":54601,"journal":{"name":"Plant Species Biology","volume":"316 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141197856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollen‐collecting insects, such as bees, associate stamens with pollen (a reward) essential for brood rearing. In some dioecious plants, female flowers have stamens with sterile pollen grains to mimic male flowers. It is not yet fully understood whether females offer less nutritious pollen to pollinators in order to conserve nutrition. Here, we tested this hypothesis in a perennial vine, Actinidia polygama, which bears nectarless flowers. We quantified flower production and measured the dry mass of floral parts as well as carbon and nitrogen concentrations in floral parts and pollen in both sexes. Males produced more flowers per inflorescence and more inflorescences per shoot than females, while the dry mass of each flower was greater in females. The carbon allocation pattern was similar to that of biomass, but nitrogen allocation exhibited a remarkable reduction in sterile stamens and pollen of female flowers. In addition, as sterile pollen of females was sparse, when compared at the same volume, it was lighter than the pollen of males. Sterile pollen produced in female flowers appears to be as voluminous as that of male flowers but extremely poor in nutrients, especially in nitrogen, which clearly suggests that A. polygama females deceive pollen‐collecting pollinators for brood rearing.","PeriodicalId":54601,"journal":{"name":"Plant Species Biology","volume":"45 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141198160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies were performed at the Department of Ancash, Peru, at ca. 4250 m a.s.l., from June to November 2022. The breeding system was studied through controlled pollinations in plants excluded from pollinators (bagged). Natural pollination was studied in the field and through photos and videos. The flowers are nectariferous and non-protandrous and present the longest lifespan reported so far for a neotropical terrestrial orchid (53–80 days). This species is pollinator dependent (unable to set fruit and seed without the agency of pollinators) and self-compatible. The observed pollinators belong to three functional groups that appeared successively (in order of appearance): hummingbirds (Chalcostigma stanleyi), bumblebees (Bombus coccineus and Bombus rubicundus), and solitary Halictidae bees (Augochlorella sp.). All recorded pollinators probe the flowers for nectar. The pollinaria adhere to the bee mouthparts and onto the lateral side of the hummingbird bill. Bumblebees were the most frequent and efficient functional group (up to 62.07% of the observed pollination events), followed by Halictidae (31.03%) and hummingbirds (6.90%). Natural fruiting success is high (66.66%–94.49%). Such high natural fruiting success is unexpected at high altitudes, but it is likely explained by a combination of factors, including the long floral lifespan, nectar secretion, and self-compatibility. This is the first report of hummingbirds as pollinators of Cranichidinae orchids, and G. valida is, to the best of our knowledge, a neotropical orchidoid orchid with the most generalist pollination biology recorded so far.","PeriodicalId":54601,"journal":{"name":"Plant Species Biology","volume":"19 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140148023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study focused on Drosera indica (Droseraceae) in tropical Thailand and its phylogenetically related species Drosera toyoakensis in temperate Japan. Drosera indica in Thailand has green leaf blades with red tentacles when flowering, making the entire trap appear red. In contrast, D. toyoakensis in Japan has green leaf blades with green-white tentacles when flowering, and the entire trap appears white. Field observations revealed statistically significant differences in taxa and size of prey caught by D. indica and D. toyoakensis. Both species caught small flies, but D. toyoakensis additionally caught larger flies and butterflies, including pollinators. These differences in prey composition may reflect differences in trap coloration that evolved under different selection pressures for capturing prey. However, trap coloration and prey assemblages were influenced by various factors, and further research is required to elucidate their evolutionary significance.","PeriodicalId":54601,"journal":{"name":"Plant Species Biology","volume":"34 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140099730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings indicate that individuals exposed to both drought conditions decreased in height and bore fewer leaves but increased in the ratio of root length to dry mass. The number of flowers produced per day and the overall flower production were higher in plants under control conditions. We found no differences in the onset of flowering between the treatments, but the plants exposed to low drought showed peak flowering earlier. Among the morphometric traits, flower height, floral diameter, petal length, and petal width were significantly lower in both drought conditions.

In the white oak species in Japan Quercus crispula, the subalpine shrubby variety Q. crispula var. horikawae (Qch) has been recognized in central and northern Honshu. Although Qch has different phenotypes from Q. crispula var. crispula (Qcc), genetic divergence between Qcc and Qch has not been examined yet. Pairs of Qcc and Qch populations in eight locations and additional Qcc and Qch populations around these locations were investigated. Leaf size of Qch was smaller than that of Qcc. Chloroplast DNA haplotypes were shared between the Qcc and Qch populations. In genotypes at 29 nuclear microsatellite loci, genetic diversity did not differ between the Qcc and Qch populations. Principal component analysis and a neighbor-joining tree of populations based on the genotypes demonstrated that 13 Qcc populations and eight Qch populations were grouped separately, except for three Qch populations that were grouped to Qcc. Climatic conditions in the eight Qch populations were characterized by lower temperature and heavier snowfall than those in the 16 populations of the genetic group of Qcc. These results suggest genetic divergence between Qcc and Qch associated with subalpine climatic conditions, irrespective of leaf size. The origin of the subalpine Qch lineage and the history of ecotypic divergence should be investigated in future genomic studies.","PeriodicalId":54601,"journal":{"name":"Plant Species Biology","volume":"6 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139967670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some flowers are also visited by nectar robbers, which feed on nectar through holes cut in floral tissue. If nectar robbers alter nectar microbial communities, they might have unexpected impacts on pollinator visitation. We investigated whether robbing could affect nectar microbial communities directly, by introducing microbes, or indirectly, by triggering a plant response to floral damage. We applied four treatments to flowers of Tecoma × “Orange Jubilee” (Bignoniaceae) in an arboretum setting: flowers were (1) covered to exclude all visitors; (2) available to both pollinators and nectar robbers and robbed naturally by carpenter bees; (3) available to pollinators only but cut at the base to simulate nectar robbing damage; or (4) available to pollinators only. We found that nectar in flowers accessible to any visitors was more likely to contain culturable microbes than flowers from which visitors were excluded. Microbial community composition and beta diversity were similar across treatments. Among flowers containing culturable microbes, flowers available to pollinators and nectar robbers had higher microbial abundance than flowers with simulated robbing, but there were no differences between flowers available to pollinators and robbers and unwounded flowers from which robbers were excluded. Overall, our results suggest that floral damage can affect some features of nectar microbial communities, but specific effects of nectar robbing are limited compared with the influence of visitation in general.","PeriodicalId":54601,"journal":{"name":"Plant Species Biology","volume":"22 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139483378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, very few attempts have investigated size-dependent resource allocation among clonal reproduction, female function, and male function within a species. Moreover, how clonal reproduction and sexual reproduction interact to influence size-dependent sex allocation has not been explored. In this study, we investigated the size dependency of clonal reproduction and sex allocation and how clonal reproduction and sexual reproduction interact to influence size-dependent female function, male function, and sex allocation in the monoecious Begonia emeiensis. Individuals with no reproduction, reproducing clonally through bulbils, reproducing sexually through flowers, and reproducing through both bulbils and flowers differed significantly from each other in terms of size (leaf area), suggesting a threshold size for clonal versus sexual reproduction. Bulbil number per individual increased with size regardless of flower production. In contrast, the relationship between size and female and male flower production per individual was influenced by bulbil production; both female and male flower numbers per individual increased with size at a slower rate for individuals reproducing clonally and sexually than for those reproducing only sexually. The ratio of female to male flowers per individual increased with size independent of bulbil production. Our study shows that the size dependency of clonal reproduction was unlikely to be influenced by sexual reproduction; however, the size dependency of female and male function was influenced by clonal reproduction.","PeriodicalId":54601,"journal":{"name":"Plant Species Biology","volume":"186 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139054038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
