Leaves and sporangia developed in rare non-Fibonacci spirals in early leafy plants [PDF]

open access: yes, 2023
Lateral plant organs, including leaves and reproductive structures, are arranged on stems in distinct patterns, termed phyllotaxis. Most extant plants exhibit phyllotactic patterns that are mathematically described by the Fibonacci series.

Perspectives on Structural, Physiological, Cellular, and Molecular Responses to Desiccation in Resurrection Plants

open access: yesScientifica, Volume 2018, Issue 1, 2018., 2018
Resurrection plants possess a unique ability to counteract desiccation stress. Desiccation tolerance (DT) is a very complex multigenic and multifactorial process comprising a combination of physiological, morphological, cellular, genomic, transcriptomic, proteomic, and metabolic processes.

Global assessment of aquatic Isoëtes species ecology

open access: yesFreshwater Biology, Volume 69, Issue 10, Page 1420-1437, October 2024.
Abstract Isoëtes are iconic but understudied wetland plants, despite having suffered severe losses globally mainly because of alterations in their habitats. We therefore provide the first global ecological assessment of aquatic Isoëtes to identify their environmental requirements and to evaluate if taxonomically related species differ in their ecology.
