Diversity and Community Structure Underlie Divergence in Thermal Strategies Across Tropical Elevations. [PDF]

Ecol Evol
We examined how community diversity and phylogenetic context are associated with plant thermal strategies along a tropical elevational gradient in the Brazilian Atlantic Forest, using Pitcairnia flammea as a focal species. By integrating community surveys, phylogenetic structure, functional traits, and experimental estimates of heat and cold tolerance,

Post-seminal development and cryopreservation of endemic or endangered bromeliads [PDF]

Anais da Academia Brasileira de Ciências, 2021
Vriesea bahiana, Hohenbergia castellanosii and Encholirium spectabile are endemic Brazilian species that are considered endemic or endangered. Development of strategies to conserve these species is important to prevent irreversible genetic erosion.

Genome Skimming Reveals Widespread Hybridization in a Neotropical Flowering Plant Radiation

Frontiers in Ecology and Evolution, 2021
The tropics hold at least an order of magnitude greater plant diversity than the temperate zone, yet the reasons for this difference are still subject to debate.

Evolution of UV reflection in bee- and bird-pollinated flowers. [PDF]

Plant Biol (Stuttg)
Pollinators shape floral UV reflection across angiosperms, supporting the bee‐avoidance hypothesis in red flowers and revealing mixed patterns in white and yellow flowers. Abstract Floral colour is a key trait mediating plant–pollinator interactions, with UV reflection hypothesized to evolve in response to the effectiveness of pollinators.

Translocation of the epiphytic bromeliad Vriesea incurvata: an efficient tool for biodiversity restoration in the Atlantic Forest

Revista Brasileira de Ciências Ambientais, 2022
Micropropagation of epiphytic bromeliads associated to translocation may act as an important tool for conservation, restauration or mitigation initiatives.

Effects of low nitrogen supply on biochemical and physiological parameters related to nitrate and water, involving nitrate transporters and aquaporins in Citrus macrophylla

Plant Biology, Volume 25, Issue 6, Page 944-955, October 2023., 2023
Reduction of nitrogen fertilization in Citrus sp. impacts physiology, revealing a new relationship between aquaporins, nitrate transporters, and growth of new leaves as a mechanism for ensuring growth. Abstract A reduction in chemical N‐based fertillizer was investigated in Citrus plants.

Acid waters in tank bromeliads: Causes and potential consequences

American Journal of Botany, Volume 110, Issue 1, January 2023., 2023
Abstract Premise The consequences of acidity for plant performance are profound, yet the prevalence and causes of low pH in bromeliad tank water are unknown despite its functional relevance to key members of many neotropical plant communities. Methods We investigated tank water pH for eight bromeliad species in the field and for the widely occurring ...

Spatiotemporal Variation on Fertility, Mating System, and Gene Flow in Vriesea gigantea (Bromeliaceae), an Atlantic Forest Species

Frontiers in Forests and Global Change, 2022
Knowledge of the patterns of variation in plant mating systems and fitness, in the context of conservation biology, is essential for understanding microscale differences and their probable causes.

AngleCam: Predicting the temporal variation of leaf angle distributions from image series with deep learning

Methods in Ecology and Evolution, Volume 13, Issue 11, Page 2531-2545, November 2022., 2022
Abstract Vertical leaf angles and their variation through time are directly related to several ecophysiological processes and properties. However, there is no efficient method for tracking leaf angles of plant canopies under field conditions. Here, we present AngleCam, a deep learning‐based approach to predict leaf angle distributions from horizontal ...

An organ‐specific transcriptomic atlas of the medicinal plant Bletilla striata: Protein‐coding genes, microRNAs, and regulatory networks

The Plant Genome, Volume 15, Issue 2, June 2022., 2022
Abstract As one of the important species belonging to the Bletilla genus of Orchidaceae, Bletilla striata (Thunb.) Rchb. f., possesses both ornamental and medicinal values. Its dried tubers are used as a traditional Chinese medicine, and several secondary metabolites have been indicated to be the active ingredients.
