Sentence examples for high light stress from inspiring English sources

Moreover, the upward inclined leaf type also avoided high light stress and maintained leaf gas exchange traits under heat stress.

Under high light stress, HRW decreases the levels of O2 − and H2O2 and elevates the activities of antioxidants, including SOD, CAT, APX and GR (Zhang et al. 2015a).

In Synechococcus sp. PCC 7942, phycobilisome degradation and other acclimation responses after nutrient or high light stress require activation by the phosphorylation-independent response regulator NblR.

It was previously reported that high light stress results in the induction of the cytosolic APX and protects the cytosol and other cellular compartments from high light induced oxidative stress (Mittler 2002; Mullineaux and Karpinski 2002).

Some important antioxidant enzymes (SOD, APX and CAT) of K. alvarezii increased their activities when K. alvarezii thalli is exposed to the cold and high light stress (Barros et al. 2006).

Previous studies also indicated that it is involved in survival from high light stress [ 54].

Simulations with shoots at the canopy top of Betula and Quercus revealed that steeper leaf angle and higher stomatal conductance of Betula contribute to maintaining a high photosynthetic activity by reducing high light stresses, such as heat load and photoinhibition.

Fischer et al. ([2006]) showed that cells of the same species were more susceptible to high-light stress under high CO2 concentrations than under low concentrations.

This experimental study using unialgal cultures revealed that both O. smithii and O. itoi utilize only the efficient violaxanthin cycle for photoprotection as a dissipation system of surplus energy under prolonged high-light stress, although they possess chlorophyll c with diadinoxanthin.

In this context, chloroplastic DHAR must be physiologically indispensable for photoprotection mechanisms particularly when leaves are exposed to high-light stress conditions.

R1/b1 transcription factors, including In1 transcription factor, control anthocyanin biosynthesis, which have been shown to protect plant tissues from photoinhibition, or high-light stress [ 54].
