A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant

New Phytologist, Volume 249, Issue 5, Page 2386-2401, March 2026.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

Evolutionary Convergence of C4 Photosynthesis: A Case Study in the Nyctaginaceae

Frontiers in Plant Science, 2020
C4 photosynthesis evolved over 65 times, with around 24 origins in the eudicot order Caryophyllales. In the Caryophyllales family Nyctaginaceae, the C4 pathway is known in three genera of the tribe Nyctagineae: Allionia, Okenia and Boerhavia ...

Rubisco evolution in C4 eudicots: an analysis of Amaranthaceae sensu lato [PDF]

, 2015
BACKGROUND Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyses the key reaction in the photosynthetic assimilation of CO₂. In C₄ plants CO₂ is supplied to Rubisco by an auxiliary CO₂-concentrating pathway that helps to maximize the ...

Transcriptomic prey‐capture responses in convergently evolved carnivorous pitcher plants

New Phytologist, Volume 249, Issue 5, Page 2559-2573, March 2026.
Summary The Australian pitcher plant Cephalotus and the Asian pitcher plant Nepenthes exhibit striking morphological and functional similarities, serving as compelling examples of convergent evolution. Although trapping pitchers in both lineages represent some of the most elaborate leaf structures in angiosperms, it remains unknown whether their ...

The complete chloroplast genome sequence of Opuntia sulphurea (Cactaceae)

Mitochondrial DNA. Part B. Resources, 2022
Opuntia sulphurea Gillies ex Salm-Dyck 1834 (Cactaceae) acts as an invasive species due to its ability to survive in various environments. In this study, we assembled the complete chloroplast (cp) genome of Opuntia sulphurea, which was 122,740 bp in ...

Exploring the Phytochemical Landscape of the Early-Diverging Flowering Plant Amborella trichopoda Baill. [PDF]

, 2019
Although the evolutionary significance of the early-diverging flowering plant Amborella (Amborella trichopoda Baill.) is widely recognized, its metabolic landscape, particularly specialized metabolites, is currently underexplored.

Portulaca eggliana (Portulacaceae), a new species from the Brazilian Amazonian savannas

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
A new species of Portulacaceae from the Amazonian savannas of northern Brazil is herein described and illustrated. Portulaca eggliana is morphologically related to P. umbraticola, but differs in the number of involucral leaves, sepal morphology, bracteole shape, and seed surface.

Nuclear DNA of plastid origin (NUPTs), neglected driver of genome variation and evolutionary innovation

The Plant Journal, Volume 125, Issue 3, February 2026.
Significance Statement Contrary to expectation, NUPTs do not necessarily have a deleterious or ultimately neutral impact, nor are they necessarily purged from the genome. Instead, they can proliferate and eventually become fixed, generating new and novel genes, gene regions and regulatory elements, thereby significantly contributing to plant nuclear ...

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.
