Erratum: Genetically encoded fluorescent sensors reveal dynamic regulation of NADPH metabolism

Plant mitochondria move dynamically inside cells and this movement is classified into two types: directional movement, in which mitochondria travel long distances, and wiggling, in which mitochondria travel short distances. However, the underlying mechanisms and roles of both types of mitochondrial movement, especially wiggling, remain to be determined. Here, we used confocal laser-scanning microscopy to quantitatively characterize mitochondrial movement (rate and trajectory) in Arabidopsis thaliana mesophyll cells. Directional movement leading to long-distance migration occurred at high speed with a low angle-change rate, whereas wiggling leading to short-distance migration occurred at low speed with a high angle-change rate. The mean square displacement (MSD) analysis could separate these two movements. Directional movement was dependent on filamentous actin (F-actin), whereas mitochondrial wiggling was not, but slightly influenced by F-actin. In mesophyll cells, mitochondria could migrate by wiggling, and most of these mitochondria associated with chloroplasts. Thus, mitochondria migrate via F-actin-independent wiggling under the influence of F-actin during their association with chloroplasts in Arabidopsis.

Erratum: Genetically encoded fluorescent sensors reveal dynamic regulation of NADPH metabolism

Abstract: In the version of this article initially published, the expression (g 1 , g 2 ) used to describe a sample subset in the Figure 1 legend was incorrect. The correct expression is (I g (S 1 ), I g (S 2 )). The error has been corrected in the HTML and PDF versions of the article.
