Evolution of photoperiod sensing in plants and algae
En portadaEvolution of photoperiod sensing in plants and algae Las plantas son capaces de reconocer de forma precisa tanto el paso de las estaciones, como el fotoperiodo, es decir, la longitud del día. Este hecho les sirve para tomar decisiones fundamentales...
Negative Regulation of Autophagy by Sulfide is Independent of Reactive Oxygen Species
Accumulating experimental evidence in mammalian, and recently plant, systems has led to a change in our understanding of the role played by hydrogen sulfide in life processes. In plants, hydrogensulfide mitigates stress and regulates important plant processes such as...

The chloroplast NADPH thioredoxin reductase C, NTRC, controls non-photochemical quenching of light energy and photosynthetic electron transport in Arabidopsis
High irradiances may lead to photooxidative stress in plants, and non-photochemical quenching (NPQ) contributes to protection against excess excitation. One of the NPQ mechanisms, qE, involves thermal dissipation of the light energy captured. Importantly, plants need...
