Arabidopsis Phytochrome D Is Involved in Red Light-Induced Negative Gravitropism of Hypocotyles
Published 2014-08-01Get full textThe phytochrome gene family, which is in Arabidopsis thaliana, consists of phytochromes A-E (phyA to phyE), regulates plant responses to ambient light environments. PhyA and phyB have been characterized in detail, but studies on phyC to phyE have reported discrepant functions. In this study, we show...

Pyrite alteration and neoformed magnetic minerals in the fault zone of the Chi‐Chi earthquake (Mw7.6, 1999): Evidence for frictional heating and co‐seismic fluids
Published 2012-08-01Get full textDuring an earthquake, physical and chemical transformations lead to alteration and formation of minerals in the gouge layer. Altered and neoformed minerals can be used as tracers of some earthquake processes. In this study, we investigate pyrite and magnetic minerals within the host Chinshui siltsto...
