Environmental influences on the maximum quantum yield of terrestrial primary production

New Phytologist, Volume 251, Issue 4, Page 1709-1722, August 2026.
Temperature and aridity effects on terrestrial ecosystems' intrinsic quantum yield. Summary Historically, terrestrial biosphere models (TBMs) have assigned the intrinsic (maximum) quantum yield of photosynthesis (ϕ0) a constant value for each plant functional type. However, experimental studies have shown that ϕ0 – when measured on light‐adapted leaves

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

The Long-Term Changes in Midday Photoinhibition in Rice (Oryza sativa L.) Growing under Fluctuating Soil Water Conditions

Plant Production Science, 2013
Rice crops growing under fluctuating soil water conditions in a rainfed field frequently experience severe photoinhibition at midday, potentially decreasing their biomass production.

Dysfunction of Chloroplast Protease Activity Mitigates pgr5 Phenotype in the Green Algae Chlamydomonas reinhardtii

Plants
Researchers have described protection mechanisms against the photoinhibition of photosystems under strong-light stress. Cyclic Electron Flow (CEF) mitigates electron acceptor-side limitation, and thus contributes to Photosystem I (PSI) protection ...

Moderate Shading Improves Growth, Photosynthesis, and Physiological Traits in Spuriopinella brachycarpa (Kom.) Kitag.

Plants
To investigate the effects of varying degrees of shading on the photosynthetic characteristics of Spuriopinnella brachycarpa (Kom.) Kitag. experiments were conducted under five shading treatments: 0% (full sunlight), 20%, 40%, 60%, and 80%.

Photoinhibition and Photoprotection under Environmental Stresses

Abiotic and Biotic Stress Journal, 2015
Plants are often exposed in their habitat to multiple abiotic and biotic stresses (e.g. high light intensity, low or high temperatures, water shortage, salinity, diseases, etc.) that hamper growth and productivity; however plants are able, to some extent, to cope with limiting environmental conditions by means of different mechanisms that contribute to

Light Stress Detection in Ficus elastica with Hyperspectral Indices

AgriEngineering
The development of methods to detect plant stress is not only a scientific challenge, but is also of great importance for agriculture and forestry. However, at present, stress diagnostics based on plant spectral characteristics has several limitations ...
