Abstract Aim Biodiversity information is the focus of major initiatives aimed at assembling large‐scale primary‐data documentation (‘digital accessible knowledge’) distribution life on E arth. Recent efforts within B razil have assembled a massive amount such for razilian plants, which we analyse in this study. Our aim to identify areas representing gaps current knowledge; these can guide future botanical exploration and discovery razil. Location Brazil. Methods We assessed angiosperm...
Addressing the challenges of biodiversity conservation and sustainable development requires global cooperation, support structures, new governance models to integrate diverse initiatives achieve massive, open exchange data, tools, technology. The traditional paradigm sharing scientific knowledge through publications is not sufficient meet contemporary demands that require only results but also knowledge, skills analyze data. E-infrastructures are key in facilitating access data providing...
Laticifer occurrence and structure are poorly known in Sapindaceae. Occurrence is likely underestimated owing to the low production of latex most species. We investigated 67 species from 23 genera Sapindaceae verify laticifer their structural, developmental chemical features, as well evolutionary history family. Shoots were collected herbarium fresh specimens for histological analyses. Three characters derived features coded ancestral states reconstructed through Bayesian stochastic mapping...
Abstract Premise Gelatinous (G)‐fibers are specialized fibers that generate tensile force to bend and straighten many plant organs; this phenomenon has been intensively studied in tension wood of trees. Previous work shown G‐fibers common within the stems twining vines, but we lack spatiotemporal developmental data required determine whether, or how, contribute movement and/or stabilization tissues. Methods We employed multiple histochemical approaches characterize formation cell wall...
Organ chirality in plants has been linked to cytoskeletal organization, as demonstrated Arabidopsis thaliana twisted mutants, where left-skewed cortical microtubules are associated with right-handed twisting, and vice versa. While this phenotype seemingly mirrors vining activity, hypothesis remains understudied within naturally twining plants. Qualitative observations identified skewed the stem of Ipomoea nil vine, suggesting parallels studies. To further investigate organ plants, we used...
The tribe Bignonieae includes all Neotropical lianescent Bignoniaceae. leaves of are generally 2- or 3-foliolate, with terminal leaflets modified into a tendril. These tendrils have varied morphologies and thought to been involved in the diversification Bignonieae. Little, however, is still known about biology evolution tendrils. This study investigated development tendril types order further understand how changes leaf morphogenesis led current patterns variation morphology. For that, we...
Summary EUBrazilOpenBio is a collaborative initiative addressing strategic barriers in biodiversity research by integrating open access data and user‐friendly tools widely available Brazil Europe. The project deploys the EU‐Brazil Hybrid Data Infrastructure that allows sharing of hardware, software on‐demand. This infrastructure provides to several integrated services resources seamlessly aggregate taxonomic, climate data, used processing implementing checklist cross‐mapping ecological niche...
Summary Leaves have undergone structural modifications over evolutionary time, and presently exist in many forms. For instance, F abaceae B ignoniaceae, leaf parts can be modified into tendrils. Currently, no data are available on genic control of tendrilled development outside Fabaceae. Here, we conducted a detailed study three representatives ignonieae: A mphilophium buccinatorium , D olichandra unguis‐cati ignonia callistegioides bearing multifid, trifid, simple‐tendrilled leaves,...
Stinging trichomes are rare in plants, occurring only angiosperms, where they reported for a few genera belonging to six families. Although there is no report of stinging Apocynaceae, previous fieldwork collections Fischeria and Matelea caused us mild allergic reaction on the skin when we contacted dense indumentum plants. This fact associated with well-known presence glandular acute apex both raised suspicions that could be present family. Hence, this study aimed investigate likely...
Premise The inflorescence of Passiflora species originates from a bud complex that derives an initially undivided meristem and ultimately produces flowers tendrils. Because the development structures derived such meristems has been variously interpreted, we investigated ontogeny expression APETALA 1 ( AP ) in species. Methods anatomical 15 was analyzed using light scanning electron microscopy. We localized tissues during initiation two situ hybridization. Results In most species, first...
Abstract Morpho-anatomical studies of fruits are scarce in monocotyledons and particularly for the Brazilian species Velloziaceae, a small family monocots characteristic campo rupestre vegetation Brazil. The main fruit types found Velloziaceae poricidal loculicidal capsules, but capsule morphology is variable, which has led to discrepancies regarding descriptions terminology. In this study, we aimed analyse development obtain better understanding dehiscence elucidate describe detail...
• Premise of the study: Seed coat characteristics have historically been used to infer taxonomic relationships and are a potential source characters for phylogenetic reconstruction. In particular, seed morphoanatomy has never studied in detail Velloziaceae. One character based on surface microsculpture phylogenies, but was excluded from recent studies owing problems primary homology. This work aimed clarify origin general composition cell layers Velloziaceae propose hypotheses homology among...
ABSTRACT Gelatinous (G)-fibers are common in the stems of twining vines (twiners), but their role remain unclear given lack developmental insights. Here, we characterize anatomy G-fiber formation bean ( Phaseolus vulgaris L., Fabaceae). G-fibers exhibit cell wall organization comparable to other species, consisting cellulose and Rhamnogalacturonan-I pectins, with possible traces lignin. We show that absent actively circumnutating stems, thus these tensile fibers not associated dynamic...
Laticifers are secretory structures that produce latex, forming a specialized defense system against herbivory. Studies using anatomical approaches to investigate laticifer growth patterns have described their origin; however, mode of growth, i.e., whether is intrusive or diffuse, remains unclear. investigating how cytoskeleton filaments may influence shape establishment and lacking. In this study, we combined microtubule immunostaining developmental anatomy the in different types...
