Special Issue Information

Dear Colleagues,

The world has undergone rapid changes over the recent two hundred years, leading to the destruction and severe modification of natural environments, as well as an increase in Earth's temperature. In this context, biodiversity is facing significant threats. One of the main factors that produces and maintains diversity encompasses the complex and conditional interactions between plants and animals. Despite our progress in understanding these relationships, several aspects remain neglected, such as the importance of considering plant anatomy, morphology, and the natural history of related plants and animals.

This Special Issue of Plants invites contributions to explore how fundamental aspects of plant–animal interactions—such as plant anatomy and the natural history of plants and animals—shape the outcomes of these relationships. Additionally, environmental factors, including seasonality, play a significant role in modulating these interactions, and current climate change has affected them in noticeable ways. Therefore, this Special Issue is interested in both direct and isolated effects, as well as the more complex and integrated impacts, with regard to the outcomes of plant–animal interactions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We report the first case of flower bud galls in a species of the mainly American genus Senega (Polygalaceae), specifically in the South Andean Patagonian plant species S. salasiana. The galls were found to be induced by gall midges (Diptera, Cecidomyiidae) and mites (Acari). We also assessed their impact on plant reproduction by measuring the relationship between inflorescence density (number of inflorescences/plant cover) and gall abundance in two populations next to San Carlos de Bariloche, Patagonia, Argentina. Plant reproduction was negatively related to the number of galled inflorescences, suggesting that high levels of gall abundance strongly reduced plant reproductive success. Our study illustrates a novel case of flower galls in the genus Senega and highlights the negative impact of this type of herbivory on plant fitness. Full article

In low-light environments, plants face challenges in maximizing light acquisition for growth and reproduction. This study investigates the light-related adaptations of Ipomoea purpurea (L.) Roth, a climbing annual vine commonly known as morning glory. Field and laboratory analyses focused on the functionality of its leaf and petal interfaces. We observed that tendrils of I. purpurea enable it to climb surrounding structures, optimizing light capture. The leaves display absorption peaks at 400 nm and 700 nm, typical for plants that absorb light in the red and blue regions, with microstructural features like protrusions and folds aiding in self-cleaning. Petals, exhibiting grid-like patterns and specific reflectance spectra, attract pollinators such as bees. These functional traits, including self-cleaning mechanisms and specialized light absorption, highlight I. purpurea’s unique strategies for thriving in low-light conditions. The findings offer valuable insights into the potential use of I. purpurea for urban landscaping, vertical greening, and ornamental plant selection. Full article
