Regulation of floral senescence in Arabidopsis by coordinated action of CONSTANS and jasmonate signaling
In Arabidopsis, photoperiodic flowering is controlled by the hub gene CONSTANS (CO), while floral organ senescence is regulated by the jasmonates (JAs). As both processes are chronologically ordered, it remains unknown whether there are common regulators of both...
Carboxylate functionalized NaDy(MoO4)2 nanoparticles with tunable size and shape as high magnetic field MRI contrast agents
Uniform sodium-dysprosium double molybdate (NaDy(MoO4)2) nanoparticles having different morphologies (spheres and ellipsoids) and tunable size have been synthesized for the first time in literature. The procedure is based on a homogeneous precipitation process at...
Divergent CO2 Activation by Tuning the Lewis Acid in Iron-Based Bimetallic Systems
Bimetallic motifs mediate the selective activation and functionalization of CO2 in metalloenzymes and some recent synthetic systems. In this work, we build on the nascent concept of bimetallic frustrated Lewis pairs (FLPs) to investigate the activation and reduction...
The Role of Mre Factors and Cell Division in Peptidoglycan Growth in the Multicellular Cyanobacterium Anabaena
Bacteria in general serve two main tasks: cell growth and division. Both processes include peptidoglycan extension to allow cell expansion and to form the poles of the daughter cells, respectively. The cyanobacterium Anabaen aforms filaments of communicated cells in...
Enhanced Dihydrogen Activation by Mononuclear Iridium(II) Compounds: A Mechanistic Study
The organometallic chemistry of 4d and 5d transition metals has been vastly dominated by closed-shell states. The reactivity of their metalloradical species is though remarkable, albeit yet poorly understood and with limited mechanistic investigations available. In...
