Similar, repetitive, and non-random occurrence arrangements comprise the distribution patterns. Ferns are a group with a wide range, whose spatial patterns are often associated with spore dispersion and environmental factors. Pteridaceae is the most species-rich fern family in Brazil, present in all phytogeographic Brazilian domains. This study aimed to map the occurrence of all Pteridaceae species in Brazil to verify distribution patterns. The occurrence points of the species were obtained from the review of herbaria, and the patterns were delimited according to the congruence of the limits of species presence, and the range in Brazilian states and the biogeographical provinces. Each taxon’s range was classified as continuous and disjunct; for the first one, some subtypes were also considered: very restricted, restricted, moderately wide, and wide. The presence of 205 species was verified, with natural occurrences for Brazil. Minas Gerais and Rio de Janeiro are the richest states in the number of species, and regarding the provinces, the Atlantic and <i>Paraná</i> Forests are the richest. A total of 123 patterns were defined, 93 (173 species) for continuous, and 30 for disjunct (32 species). Considering the continuous patterns, 18 were classified as very restricted (70 species), 14 as restricted (27 species), 51 as moderately wide (63 species), and 10 as wide (13 species). The Brazilian mountain regions are home to a large number of endemic species (such as <i>Serra do Mar</i>, <i>Serra da Mantiqueira</i>, and the <i>Guiana</i> Shield). Environmental characteristics, such as rock types, humidity, precipitation, and elevation seem to be important for the species’ establishment. Furthermore, the dispersal ability of the spores must be considered, given the range of occurrence of the taxa and the age of the lineages.</p>","PeriodicalId":9140,"journal":{"name":"Brazilian Journal of Botany","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142256728","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}

In this study, we isolated <i>AaMYB4</i>, an MYB transcription factor that represses anthocyanin synthesis, from an ornamental succulent, <i>Aeonium arboreum</i> Webb &amp; Berthel ‘Halloween’. Our study incorporated gene cloning, bioinformatics, functional validation of transgenes, and yeast two-hybrid assays to investigate <i>AaMYB4</i>’s role. The finding revealed that the full-length Open Reading Frame (ORF) of <i>AaMYB4</i> spans 825 base pairs, encoding 274 amino acids. Bioinformatics analyses suggested that AaMYB4 functions as an R2R3-MYB transcription factor suppressing flavonoid biosynthesis, characterized by a typical repressive EAR motif. Functional validation of transgenes for <i>AaMYB4</i> indicated that the anthocyanin content was significantly reduced in <i>AaMYB4</i> overexpressing <i>Arabidopsis</i> compared with the WT under nitrogen deficiency, high light exposure, 6% sucrose, and abscisic acid (ABA) treatment, and the structural genes for anthocyanin synthesis were down-regulated in the <i>AaMYB4</i> transgenic <i>Arabidopsis</i>. Furthermore, in terms of transcription factors in the <i>AaMYB4</i> transgenic <i>Arabidopsis</i>, the expression levels of <i>AtPAP1</i> and <i>AtTT8</i> exhibited a significant downregulation. Yeast two-hybrid assays revealed no interaction between AaMYB4 and AaTT8, and the AaMYB4 protein can self-interact.

Here, we tested the division-of-labour hypothesis in <i>Senna occidentalis</i>, a buzz-pollinated, self-compatible, heterantherous species. The fecundity of pollen grains from long and short stamens was evaluated using hand cross-pollination experiments and by comparing the quantity, size, and quality of pollen in different sets of stamens. The visitation rate and behaviour of floral visitors were also assessed, while their preferences for different sets of stamens were checked using stamen exclusion experiments. The long-pollinating stamens produced a greater number and volume of pollen grains compared to the short-feeding stamens. The pollen grains from long stamens exhibited better germination rates with higher production of fruit and seeds than short stamen pollens in cross-pollination experiments. Nine floral visitors foraged on the flowers, and the large carpenter bees (<i>Xylocopa</i> sp.) were the most dominant and effective pollinators. The long stamens deposited pollen on the lateral and ventral thorax of large-sized pollinators, while the short stamens placed pollen on the ventral and abdomen portions. Therefore, the short stamens might produce pollen grains primarily to feed their pollinators, while the long stamens might generate pollen for pollination and successful fertilization. Further, breeding system experiments indicated a significant pollen limitation and dependency on insect pollination for the increased reproductive outputs (fruit and seed sets).

We aimed to identify characteristics that confirm the “key-lock” interaction process, anticipated in species with clustered pollen dispersion, as found in individuals of the Mimoseae tribe. Anthers and stigmas were sampled from unpollinated and pollinated flowers and processed for surface, anatomical, histochemical and ultrastructural analyses.

Each polyad is formed of eight pollen grains that have an areolate-verrucate exine, along with starch grains and protein bodies as reserve substances. The stigma is semidry, punctiform, with a central hole, cuticularized, composed of cells that secrete proteins, polysaccharides, phenolics, and oil. The discovery of eight pollen grains per polyad, with only one polyad deposited on each stigma, along with the presence of eight ovules per ovary, indicates a key-lock mechanism between the stigma and polyad.
