A calmodulin-gated calcium channel links pathogen patterns to plant immunity ($) (Nature)
Plant Science Research WeeklyCalcium ions mediate calcium-based defense responses in pattern triggered immunity (PTI) upon detection of pathogen patterns by plant surface receptors. A new study by Tian et al. has elucidated the molecular events that activate the calcium response. The authors show that adequeate calcium nutrient…
A chloroplast-localized mitochondrial calcium uniporter transduces osmotic stress in Arabidopsis (Nature Plants)
Plant Science Research WeeklyCalcium and chloroplasts are both at the heart of the signal transduction during environmental stress. Teardo et al. studied whether the chloroplast-localized mitochondrial calcium uniporter has a role in stress signaling. The group identified 6 homologs of mitochondrial calcium uniporter (MCU) in Arabidopsis,…
