Photosynthetic organisms have evolved various acclimatory responses to high-light (HL)
conditions to maintain a balance between energy supply (light harvesting and electron …

Lichens are symbiotic associations (holobionts) established between fungi (mycobionts) and
certain groups of cyanobacteria or unicellular green algae (photobionts). This symbiotic …

Lichens often grow in microhabitats where they are exposed to severe abiotic stresses such
as desiccation and temperature extremes. They are also often exposed to levels of light that …

Drought stress has multiple effects on the photosynthetic apparatus. Herein, we aimed to
study the effect of drought stress on fluorescence characteristics of PSII in leaves of …

Climate change has escalated the effect of drought on crop production as it has negatively
altered the environmental condition. Wild watermelon grows abundantly in the Kgalagadi …

Plants that are tolerant of extreme low temperatures, and plants that are tolerant of
desiccation, face similar physiological challenges, as low temperatures often result in …

The ability to dissipate large fractions of their absorbed light energy as heat is a vital
photoprotective function of the peripheral light-harvesting pigment–protein complexes in …

Chlorophyll fluorescence can be defined as the red and far-red light emitted by
photosynthetic tissue when it is excited by a light source. This is an important phenomenon …

In this study, we investigated responses of the Photochemical Reflectance Index (PRI), and
Normalized Difference Vegetation Index (NDVI) to gradual dehydration of several Antarctic …

Chromera velia is an alveolate alga associated with scleractinian corals. Here we present
detailed work on chromatic adaptation in C. velia cultured under either blue or red light …
