Light stress-induced chloroplast movement and midday depression of photosynthesis in sorghum leaves

Plant Production Science, 2020
Plants are exposed to high light intensity, high leaf temperatures and high air-to-leaf water vapor pressure deficit (ALVPD) during the day. These environmental stresses cause stomatal closure and photoinhibitory damage, leading to midday depression of ...

Arabidopsis STN7/STN8 alleviates oxidative damages via different regulatory patterns under drought stress [PDF]

Plant J
SUMMARY STN7 and STN8 kinases phosphorylate several proteins of the photosynthetic apparatus in response to changes in environmental conditions. Phosphorylation is linked to the dynamic arrangement of both the 3D structure of the thylakoid membrane and thylakoid protein complexes, thereby controlling excitation energy transfer between photosystems and ...

STED-Inspired Cationic Photoinhibition Lithography

The Journal of Physical Chemistry C, 2023
Direct laser writing by two-photon lithography has been enhanced substantially during the past two decades by techniques borrowed from stimulated emission depletion (STED) microscopy. However, STED-inspired lithography was so far limited to radical polymerizations, mostly to acrylates and methacrylates.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Chlorophyll a Fluorescence Kinetics Reveal That Ozone Stress Redistributes Electron Transport Limitations Between PSII and PSI in Wheat

Plant, Cell &Environment, EarlyView.
ABSTRACT Tropospheric ozone (O3) reduces crop productivity, but the sites at which ozone alters photosynthetic electron transport remain unclear. We tested whether acute exposure to O3 shifts the dominant site of electron transport limitation in a cultivar‐specific manner, rather than causing a uniform decline in PSII function.

Exogenous IAA application alleviated altered physiological and biochemical processes through promoting H‐ATPase and Fe chelate reductase activities in common bean (Phaseolus vulgaris L.) subjected to iron deficiency

Plant Biology, EarlyView.
Exogenous IAA supply enhances the strategy I response in common bean under iron deficiency. Abstract Iron deficiency is a common nutritional disorder observed in calcareous soils, where its resolution by classical methods has shown its failure. However, the exploitation of certain potentialities possessed by crops (rhizosphere acidification, H‐ATPase ...

Mechanisms of Photodamage and Protein Turnover in Photoinhibition [PDF]

Trends in Plant Science, 2018
Rapid protein degradation and replacement is an important response to photodamage and a means of photoprotection by recovering proteostasis. Protein turnover and translation efficiency studies have discovered fast turnover subunits in cytochrome b6f and the NAD(P)H dehydrogenase (NDH) complex, in addition to PSII subunit D1.

The involvement of photosystem II-generated H2O2 in photoinhibition [PDF]

, 1991
The involvement of H2O2 generated by photosystem II (PSII) in the process of photoinhibition of thylakoids with a functional oxygen-evolving complex (OEC) was investigated.

Performance of planted native seedlings in felled strips within Pinus radiata plantation forest

Restoration Ecology, EarlyView.
Abstract Introduction Exotic plantations could facilitate native forest restoration through a managed transition utilizing partial harvest, poisoning, or natural senescence of the plantation. Objectives To explore canopy gap creation and herbivore exclusion in a Pinus radiata plantation on planted seedlings of three native tree species.
