In plants, the major route for dissipating excess light is the nonphotochemical quenching of absorbed light (NPQ), which is associated with thylakoid lumen acidification. Our data offer an interpretation for the complex relationship between changes in luminal pH and the NPQ response. Upon steady-state illumination, fast NPQ relaxation in the dark reflects the equilibration between the electroch...

The involvement of excited and highly reactive intermediates in oxygenic photosynthesis inevitably results in the generation of reactive oxygen species. To protect the photosynthetic apparatus from oxidative damage, xanthophyll pigments are involved in the quenching of excited chlorophyll and reactive oxygen species, namely 1Chl*, 3Chl*, and 1O2*. Quenching of 1Chl* results in harmless dissipat...

Oxygen-evolving photosynthetic organisms possess nonphotochemical quenching (NPQ) pathways that protect against photo-induced damage. The majority of NPQ in plants is regulated on a rapid timescale by changes in the pH of the thylakoid lumen. In order to quantify the rapidly reversible component of NPQ, called qE, we developed a mathematical model of pH-dependent quenching of chlorophyll excita...

In Epstein-Barr virus (EBV)-associated tumors in nonimmunocompromised patients, EBV gene expression is highly restricted. EBV-encoded nuclear antigen (EBNA)-1 is expressed, whereas the immunogenic and proliferative EBNAs are not. This pattern of EBNA expression is generated by usage of the BamHI-Q promoter (Qp). We have determined that the JAK/STAT pathway positively regulates Qp activity. In t...

— Colmez has given a recipe to associate a smooth modular representation Ω(W ) of the Borel subgroup of GL2(Qp) to a Fp-representation W of Gal(Qp/Qp) by using Fontaine’s theory of (φ,Γ)-modules. We compute Ω(W ) explicitly and we prove that if W is irreducible and dim(W ) = 2, then Ω(W ) is the restriction to the Borel subgroup of GL2(Qp) of the supersingular representation associated to W in ...

Four evergreen broadleaf Rhododendron spp. (Rhododendrons), namely, aganniphum, R. nyingchiense, wardii, and triflorum, occur in harsh subalpine habitats the southwest Qinghai-Tibet Plateau (QTP), China. Considering that four Rhododendrons cannot escape their unique environment, they must evolve a set of adaptations to survive, but information is lacking. To uncover physiological adaptation cha...

BACKGROUND AND AIMS Cost-benefit models predict that carnivory can increase the rate of photosynthesis (A(N)) by leaves of carnivorous plants as a result of increased nitrogen absorption from prey. However, the cost of carnivory includes decreased A(N) and increased respiration rates (R(D)) of trapping organs. The principal aim of the present study was to assess the costs and benefits of carniv...
