Moderate photoinhibition of photosystem II protects photosystem I from photodamage at chilling stress in tobacco leaves

Frontiers in Plant Science, 2016
It has been indicated that photosystem I (PSI) is susceptible to chilling-light stress in tobacco leaves, but the effect of growth light intensity on chilling-induced PSI photoinhibition in tobacco is unclear.

Biochemical and biotechnological approaches as basis for structure determination of pigment-protein complexes of oxygenic photosynthesis

, 2009
Today the structure of photosystem II, which is the enzyme responsible for the evolution of molecular oxygen by plants, algae and cyanobacteria, is known up to a resolution of about 3.0 Å in cyanobacteria (Loll et al., 2005).

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Quality control of Photosystem II: the mechanisms for avoidance and tolerance of light and heat stresses are closely linked to membrane fluidity of the thylakoids

Frontiers in Plant Science, 2016
When oxygenic photosynthetic organisms are exposed to excessive light and/or heat, Photosystem II is damaged and electron transport is blocked. In these events, reactive oxygen species, endogenous radicals and lipid peroxidation products generated by ...

Transcriptomic stress responses in Vaccinium spp. F1 hybrids: Implications for temperature‐resilient cranberry breeding using a crop wild relative

PLANTS, PEOPLE, PLANET, EarlyView.
Climate extremes threaten the sustainability of cranberry production, a culturally and economically important North American crop. This study demonstrates that wild cranberries (Vaccinium oxycoccos) harbor genetic variation that may enhance cold stress resilience when introduced into cultivated cranberry through hybridization.

Use of chlorophyll fluorescence and P700 absorbance to rapidly detect glyphosate resistance in goosegrass (Eleusine indica)

Journal of Integrative Agriculture, 2015
The rapid detection of glyphosate resistance in goosegrass (Eleusine indica) will enhance our ability to respond to new resistant populations of this major weed.

Suitability of slightly saline irrigation for alleviating drought stress in taro and yam in Tonga: Implications for climate‐resilient Pacific cropping systems

PLANTS, PEOPLE, PLANET, EarlyView.
There is an increasing risk of drought and salinisation of soil and groundwater globally, including in Pacific Island countries such as Tonga. Irrigating crops with slightly saline water, such as that produced by emerging desalination technologies, could help to alleviate droughts.

Acyl lipids in the supramolecular chlorophyll-protein complexes of photosystems - isolation artifacts or integral components regulating their structure and functions?

Acta Societatis Botanicorum Poloniae, 2014
The precise nature of interactions between the chloropnyll-protein complexes related to photosystem I or photosystem II and the acyl lipids in the thylakoid membranes is not yet fully elucidated.

The structure and function of eukaryotic photosystem I

, 2011
Eukaryotic photosystem I consists of two functional moieties: the photosystem I core, harboring the components for the light-driven charge separation and the subsequent electron transfer, and the peripheral light-harvesting complex (LHCI).
