A star in a 15.2-year orbit around the supermassive black hole at the centre of the Milky Way

R Schödel, T Ott, R Genzel, R Hofmann, M Lehnert… - Nature, 2002 - nature.com
Many galaxies are thought to have supermassive black holes at their centres 1 —more than
a million times the mass of the Sun. Measurements of stellar velocities 2 , 3 , 4 , 5 , 6 , 7 and …

Regulation of signal transduction and bacterial infection during root nodule symbiosis

C Popp, T Ott - Current opinion in plant biology, 2011 - Elsevier
Among plant–microbe interactions, root nodule symbiosis is one of the most important beneficial
interactions providing legume plants with nitrogenous compounds. Over the past years …

Perspectives on remorin proteins, membrane rafts, and their role during plant–microbe interactions

IK Jarsch, T Ott - Molecular plant-microbe interactions, 2011 - Am Phytopath Society
Invasion of host cells by pathogenic or mutualistic microbes requires complex molecular
dialogues that often determine host survival. Although several components of the underlying …
