It is proposed that Arabidopsis possesses an inherent and heritable ability to sense and respond to elevated, yet balanced chromosome numbers, and the impact of natural variation on alteration of autotetraploid gene expression stresses its potential importance in the evolution and breeding of plants.

The most important finding of this work is that neo-tetraploid lines exhibit considerable stability through all the generations tested, which will help to unravel the consequences of polyploidy, particularly tetraploidsy, on the genome, on gene expression and on natural diversity in Arabidopsis.

Light attenuation and antioxidation are the main mechanisms of photoprotection by anthocyanin under high light (HL) stress. Anthocyanin synthase (ANS) is the key enzyme in the downstream portion of…
Variations in photoprotective potential along gradients of leaf development and plant succession in subtropical forests under contrasting irradiances
Functional characteristics of phenolic compounds accumulated in young leaves of two subtropical forest tree species of different successional stages
The results indicate that the biosynthesis of phenolic compounds in young leaves is likely enhanced by an imbalance between photosynthetic electron supply and demand and that flavonoids play a larger role in meditating photoprotection in late-successional species than in early- successional ones.
The major photoprotective role of anthocyanins in leaves of Arabidopsis thaliana under long-term high light treatment: antioxidant or light attenuator?
Analysis of physiological and biochemical responses to HL of three Arabidopsis thaliana lines indicates that the light attenuation role of anthocyanins is more important than their antioxidant role in photoprotection.
Overexpression of the V-ATPase c subunit gene from Antarctic notothenioid fishes enhances freezing tolerance in transgenic Arabidopsis plants.
Different photoprotection strategies for mid- and late-successional dominant tree species in a high-light environment in summer
The relationship between anthocyanin accumulation and photoprotection in young leaves of two dominant tree species in subtropical forests in different seasons.
To adapt to seasonal changes anthocyanins, other antioxidative substances and antioxidative enzymes, as well as components involved in the safe dissipation of excitation energy as heat need to cooperate with one another.
Photosynthetic compensation of non-leaf organ stems of the invasive species Sphagneticola trilobata (L.) Pruski at low temperature
The discovery of the physiological and adaptive mechanisms of the stem of S. trilobata to low temperature will provide a theoretical basis for explaining how it maintains its annual growth in South China and is of great significance for predicting the future spread of cloned and propagated invasive plants.
