Effects of light on cyanide-resistant respiration and alternative oxidase function in Arabidopsis seedlings.
TLDR
Red light and blue light-induced AOX (especially AOX1a) expressions were characterized and it is suggested that more reduction of the photosynthetic electron transport chain and more accumulation of reducing-equivalents in the mutant during de-etiolation might be the main reasons.
Exogenous Melatonin Alleviates Oxidative Damages and Protects Photosystem II in Maize Seedlings Under Drought Stress
TLDR
The results showed that drought stress led to the rise in reactive oxygen species (ROS), severe cell death, and degradation of D1 protein, which were mitigated by the melatonin application, which improved the photosynthetic activities and alleviated the oxidative damages of maize seedlings under the drought stress.
Red blood cell extrudes nucleus and mitochondria against oxidative stress
TLDR
Nuclear and mitochondrial extrusion may help mammal erythrocytes to better adapt to high‐sugar and high‐heme conditions by limiting ROS generation.
Phosphorylation of photosynthetic antenna protein CP29 and photosystem II structure changes in monocotyledonous plants under environmental stresses.
TLDR
It was found that most CP29 phosphorylation was accompanied by its lateral migration from granum membranes to stroma-exposed thylakoid regions, and the instability of PSII supercomplexes and LHCII trimers under environmental stresses.
Comparative expression analysis of dehydrins between two barley varieties, wild barley and Tibetan hulless barley associated with different stress resistance
TLDR
T Tibetan Heiqingke No. 1 accumulated higher abundance of dehydrins than stress-sensitive wild barley under all stress conditions, which indicated that cells of wild barley received more damages than Tibetan hulless barley.

Exogenous melatonin enhances salt stress tolerance in maize seedlings by improving antioxidant and photosynthetic capacity.
TLDR
It is found that application of exogenous melatonin alleviated reactive oxygen species burst and protected the photosynthetic activity in maize seedlings under salt stress through the activation of antioxidant enzymes.
Influence of stripe rust infection on the photosynthetic characteristics and antioxidant system of susceptible and resistant wheat cultivars at the adult plant stage
TLDR
The results demonstrate that D1 and light-harvesting complex II (LHCII) phosphorylation are involved in the resistance to stripe rust in wheat and provide evidence that thylakoid protein phosphorylated and antioxidant enzyme systems play important roles in plant responses and defense to biotic stress.
The roles of two transcription factors, ABI4 and CBFA, in ABA and plastid signalling and stress responses
TLDR
It is found that once ABI4 bound the element (CCACGT), it may not be bound by other TFs, therefore making the signalling long-lasting, and transcriptional efficiency of stress-responsive genes (including the transcription co-factor CBP) is improved instantaneously.
The significance of CP29 reversible phosphorylation in thylakoids of higher plants under environmental stresses.
TLDR
This review discusses recent advancements in CP29 phosphorylation and dephosphorylation studies and its physiological significance under environmental stresses in higher plants, especially in the monocotyledonous crops.
