Plants Free FullText Potential and Challenges of

Sunlight energy largely exceeds the energy required by anthropic activities, and therefore its exploitation represents a major target in the field of renewable energies. The interest in the mass cultivation of green microalgae has grown in the last decades, as algal biomass could be employed to cover a significant portion of global energy demand. Advantages of microalgal vs. plant biomass

Lutein is needed for efficient chlorophyll triplet

Lutein is the most abundant xanthophyll in the photosynthetic apparatus of higher plants. It binds to site L1 of all Lhc proteins, whose occupancy is indispensable for protein folding and quenching chlorophyll triplets. Thus, the lack of a visible phenotype in mutants lacking lutein has been surprising. We have reassessed the lut2.1 phenotypes through biochemical and spectroscopic methods

Anthocyanins are usually more permanent in horticultural plants because many constitutively red or variegated leaves or fruit of garden and crop plants have been selected for aesthetic reasons (Harborne, 1965).

Ultraviolet Bphotoprotection Efficiency of Mesocosm

Photoprotection against UVB radiation (UVBR 280–320 nm) was examined in natural phytoplankton communities from two coastal environments at different latitudes: temperate Rimouski (Canada) and tropical Ubatuba (Brazil). Mesocosm experiments were performed at these sites to examine the response of phytoplankton to increases in UVBR that corresponded to local depletions of 30% and 60% in

The sunscreening properties of plants

Plants produce UV screening compounds to protect themselves from the damage that excess UV radiation can cause to its photosynthesis machinery. UV radiation is therefore the detrimental factor in the amount of protection a plant will need to produce: the more sun the organism is exposed to, the greater the need for the protection.

Pentacyclic triterpenes responsible for photoprotection of

Screeningbased photoprotection is a firstline defence of plants against potentially harmful solar radiation. In the Iberian Peninsula, most natural fleshy fruits are red, purple or black, although there do exist a few plants that naturally present white fruit, such as Corema album (L.) D.Don (Ericaceae). This is a wild shrub of Atlantic coastal areas, which presents white fleshy fruit that

Brazilian Consensus on Photoprotection

Almost the entire national territory is loed between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun.

Rapid modulation of ultraviolet shielding in plants is

Whether plants can adjust this UV sunscreen protection in response to rapid changes in UV, as occurs on a diurnal basis, is largely unexplored. Here, we use a combination of approaches to demonstrate that plants can modulate their UV‐screening properties within minutes to hours, and these changes are driven, in part, by UV radiation.
