Seagrasses under stress: Independent negative effects of elevated temperature and light reduction at multiple levels of organization

Limnology and Oceanography, Volume 70, Issue S2, Page S448-S463, December 2025.
Abstract Seagrasses are important foundation species, which support coastal biodiversity and provide socioeconomic benefits. However, seagrasses are threatened by anthropogenic changes, including the elevated temperature associated with marine heatwaves (MHWs) and light limitation from eutrophication or increased sedimentation.

Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife
Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy.

Bacterial community in biological soil crusts from a Brazilian semiarid region under desertification process [PDF]

Scientia Agricola
Biological soil crusts (BSC) are commonly found in soils in the drylands regions, which can influence stabilization, water retention, nutrient cycling (particularly carbon (C) and nitrogen (N) dynamics), and several ecological processes.

Chloroplast Redox Imbalance Governs Phenotypic Plasticity: the Grand Design of Photosynthesis Revisited

Frontiers in Plant Science, 2012
Sunlight, the ultimate energy source for life on our planet, enters the biosphere as a direct consequence of the evolution of photoautotrophy. Photoautotrophs must balance the light energy absorbed and trapped through extremely fast, temperature ...

PRC2 facilitates the transition from heterotrophy to photoautotrophy during seedling emergence

Abstract Seed-to-seedling transition represents a key developmental and metabolic switch in plants. Catabolism of seed storage reserves fuels germination and early seedling emergence until photosynthesis is established. The developmental transition is controlled by Polycomb repressive complex 2 (PRC2).
