Determination of Total Soluble Sugars in Pteridophytes Using the Anthrone Method. [PDF]

open access: yesCurr Protoc
Abstract Sugars serve as crucial integrators of both internal and environmental signals in plants, shaping the regulation of diverse physiological processes that occur throughout the plant's life span, from early embryogenesis to later senescence stages. During evolution, plants have developed various strategies to cope with abiotic stress. For example,

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle. [PDF]

open access: yesConserv Biol
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

The tasiR-ARF pathway in plants: origin, functions, and interplay of miR-390, tasiRNAs and ARF3. [PDF]

open access: yesPlant Biol (Stuttg)
Trans‐acting small interfering RNAs that silence a subset of Auxin Response Factors are crucial for plant growth, developmental timing, proper organ patterning, and coping with stress. Abstract Trans‐acting small interfering RNA (tasiRNAs) are a special type of endogenous small RNAs (sRNAs) found only in plants.

Beyond species means - the intraspecific contribution to global wood density variation. [PDF]

open access: yesNew Phytol
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Climate and hybridization shape stomatal trait evolution in Populus. [PDF]

open access: yesNew Phytol
Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

Open letter: The need for a site‐based biodiversity standard measuring and certifying impacts from nature‐based projects

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Despite growing investment in restoration, weak accountability and poor biodiversity monitoring mean many projects fail to achieve ecological recovery. The Global Biodiversity Standard (TGBS) offers a practical way to ensure that restoration finance delivers measurable gains for nature.

More Science Than Art: The First Botanical Garden in Portugal (c. 1650)

open access: yesRenaissance Studies, EarlyView.
ABSTRACT Gabriel Grisley, a German physician, came to Portugal and founded a garden near the Xabregas River in Lisbon, during the 1610s under the Spanish kings' rule. In view of the utility a botanic garden represented for the kingdom, he was able to obtain a royal privilege from King João IV during the Restauration War against the Spanish (1640–1668).

Endophytic and ectomycorrhizal, an overlooked dual ecological niche? Insights from natural environments and Russula species

open access: yesNew Phytologist, Volume 250, Issue 6, Page 3946-3960, June 2026.
Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...

Hurdles to overcome to achieve biostimulant‐driven, low chemical input crop production

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 783-791, May 2026.
Crop production requires considerable chemical inputs that result in significant greenhouse gas emissions and other environmental costs. Biostimulants are natural agents, such as microorganisms or seaweed, applied to plants and soil to stimulate plant growth and reduce chemical inputs. Biostimulant use is rapidly increasing globally, but hurdles remain,

Assessing contributions of deterministic versus stochastic processes to local species assembly: A field experiment with annual plant‐dominated communities in gypsum systems

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
In this study, we experimentally show that stochasticity can play prominent roles in driving local species assembly in annual plant‐dominated communities of semiarid gypsum ecosystems. Drylands are traditionally viewed as restrictive environments that impose strong deterministic filtering effects, but neutral events can also contribute decisively to ...
