Organelle-Specific Initiation of Autophagy

Organelle biogenesis and autophagy

Is mitochondrial volume maintained during polarized cell growth? How well do cells ensure that they maintain uniform organelle distribution when they undergo polarized cell growth and subsequent division. S. Rafelski from the Marshall laboratory at University of California–San Francisco used three-dimensional, computationalmodeling methods to demonstrate that mitochondrial volume is maintained ...

Flow Cytometric Measurement of Cell Organelle Autophagy

Autophagy in protein and organelle turnover.

Macroautophagy is an evolutionarily conserved degradation system in the cell. In autophagy, intracellular components are sequestered by autophagosomes and subsequently degraded upon fusion with lysosomes. Genetic analysis of autophagy in mammals has revealed that autophagy is important for various physiological processes, such as adaptive responses to starvation, embryogenesis, quality control ...

Degradation of Organelles or Specific Organelle Components via Selective Autophagy in Plant Cells

Macroautophagy (hereafter referred to as autophagy) is a cellular mechanism dedicated to the degradation and recycling of unnecessary cytosolic components by their removal to the lytic compartment of the cell (the vacuole in plants). Autophagy is generally induced by stresses causing energy deprivation and its operation occurs by special vesicles, termed autophagosomes. Autophagy also operates ...

From organelle to organ: ZRIZI MATE-Type transporter is an organelle transporter that enhances organ initiation.

Plant architecture is a predictable but flexible trait. The timing and position of organ initiation from the shoot apical meristem (SAM) contribute to the final plant form. While much progress has been made recently in understanding how the site of leaf initiation is determined, the mechanism underlying the temporal interval between leaf primordia is still largely unknown. The Arabidopsis ZRIZI...
