The Analysis of Leaf Traits of Eight Ottelia Populations and Their Potential Ecosystem Functions in Karst Freshwaters in China

open access: yesFrontiers in Plant Science, 2019
Submerged macrophytes play a structuring role in the shallow freshwater ecosystem by increasing the heterogeneous state in freshwaters. The macrophytes in genus Ottelia were featured for their broad leaves, which might consequently produce specialized ...

Representativity of CO2 Exchange on Extensive Green Roofs: Scaling From Leaf to Plant, and Plant to Roof Scale

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract Urban green roofs have potential for local urban climate change mitigation, as they have been demonstrated to uptake carbon dioxide (CO2) from the atmosphere. However, most roofs are too small to qualify for area‐integrating direct surface‐atmosphere exchange measurements using the eddy covariance technique (EC), resulting in sparse data on ...

Orchid genome evolution and trait innovation

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 8, Page 2577-2607, August 2026.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

Techniques and challenges in studying photosynthetic diversity in freshwater submerged vascular plants

open access: yesApplications in Plant Sciences, Volume 14, Issue 4, July-August 2026.
Abstract While the photosynthetic diversity of aquatic plants rivals that of terrestrial species, the environmental conditions underlying that diversity fundamentally differ. Despite these environmental differences, aquatic and terrestrial plants have convergently evolved carbon concentrating mechanisms (CCMs).

A malic Acid permease in isolated vacuoles of a crassulacean Acid metabolism plant.

open access: yes, 1982
Vacuoles isolated from mesophyll protoplasts of the Crassulacean acid metabolism plant Bryophyllum daigremontianum take up [(14)C]l-malic acid from the medium. The initial rates of uptake show saturation kinetics (apparent K(m) about 1 millimolar).

Diel rewiring and positive selection of ancient plant proteins enabled evolution of CAM photosynthesis in Agave

open access: yesBMC Genomics, 2018
Background Crassulacean acid metabolism (CAM) enhances plant water-use efficiency through an inverse day/night pattern of stomatal closure/opening that facilitates nocturnal CO2 uptake.

Transcriptomic Analysis of the CAM Species Kalanchoë fedtschenkoi Under Low- and High-Temperature Regimes

open access: yesPlants
Temperature stress is one of the major limiting environmental factors that negatively impact global crop yields. Kalanchoë fedtschenkoi is an obligate crassulacean acid metabolism (CAM) plant species, exhibiting much higher water-use efficiency and ...
