Rydberg excitons(analogues of Rydberg atoms in condensed matter systems)are highly excited bound electron-hole states with large Bohr *** interaction between them as well as exciton coupling to light may lead to strong optical nonlinearity,with applications in sensing and quantum information ***,we achieve strong effective photon–photon interactions(Kerr-like optical nonlinearity)via the Rydberg blockade phenomenon and the hybridisation of excitons and photons forming polaritons in a Cu2O-filled *** pulsed resonant excitation polariton resonance frequencies are renormalised due to the reduction of the photon-exciton coupling with increasing exciton *** analysis shows that the Rydberg blockade plays a major role in the experimentally observed scaling of the polariton nonlinearity coefficient as∝n4.4±1.8 for principal quantum numbers up to n=*** high principal quantum numbers studied in a polariton system for the first time are essential for realisation of high Rydberg optical nonlinearities,which paves the way towards quantum optical applications and fundamental studies of strongly correlated photonic(polaritonic)states in a solid state system.

Metabolite Transporter Regulation of ABA Function and Guard Cell Response

引用

Molecular Plant 2014年第10期7卷 1505-1507页

作者： Yunqing Yu Sarah M. assmann Biology Department Pennsylvania State University 208 Mueller Laboratory University Park PA 16802–5301 USA

Pairs of guard cells form stomatal pores through which gas exchange occurs. Gas exchange includes transpirational water loss, and guard cell signaling in drought response has been studied for decades. Abscisic acid （ABA） is the major hormone that regulates drought responses. ABA and other metabolites can be synthesized in one cell type or subcellular compartment and transported across mem- branes by specific transporters to conduct biological func- tions. Two new papers, both taking advantage of reverse genetic methods, one focusing on a plasma membrane ABA efflux carrier （Zhang et al., 2014） and the other on a putative mitochondrial pyruvate carrier （Li et al., 2014）, have recently shown the importance of metabolite trans- porters in ABA function and guard cell response.

Arabidopsis Extra Large G-Protein 2 （XLG2） Interacts with the Gβ Subunit of Heterotrimeric G Protein and Functions in Disease Resistance

Heterotrimeric GTP-binding proteins, which consist of Gα, Gβ, and Gγ subunits, play important roles in transducing extracellular signals perceived by cell surface receptors into intracellular physiological responses. In addition to a single prototypical Gα protein （GPA1）, Arabidopsis has three unique Gα-Iike proteins, known as XLG1, XLG2, and XLG3, that have been found to be localized in nuclei, although their functions and mode of action remain largely unknown. Through a transcriptomic analysis, we found that XLG2 and XLG3 were rapidly induced by infection with the bacterial pathogen Pseudomonas syringae, whereas the XLG1 transcript level was not affected by pathogen infection. A reverse genetic screen revealed that the xlg2 loss-of-function mutation causes enhanced susceptibility to P. syringae. Transcriptome profiling revealed that the xlg2 mutation affects pathogen-triggered induction of a small set of defense-related genes. However, xlgl and xlg3 mutants showed no difference from wild-type plants in resistance to P. syringae, In addition, the xlg2 xlg3 double mutant and the xlgl xlg2 xlg3 triple mutant were not significantly different from the xlg2 single mutant in the disease resistance phenotype, suggesting that the roles of XLG1 and XLG3 in defense, if any, are less significant than for XLG2. Constitutive overexpression of XLG2 leads to the accumulation of abnormal transcripts from multiple defense-related genes. Through co-immunoprecipitation assays, XLG2 was found to interact with AGB1, the sole Gβ subunit in Arabidopsis, which has previously been found to be a positive regulator in resistance to necrotrophic fungal pathogens. However, no significant difference was found between three xlg single mutants, the xlg2 xlg3 double mutant, the xlgtriple mutant, and wild-type plants in resistance to the necrotrophic fungal pathogens Botrytis cinerea or Alternaria brassicicola. These results suggest that XLG2 and AGB1 are components of a G-protein complex different
