Tracheary element differentiation uses a novel mechanism coordinating programmed cell death and secondary cell wall synthesis
Tracheary element differentiation requires strict coordination of secondary cell wall synthesis and programmed cell death (PCD) to produce a functional cell corpse. The execution of cell death involves an influx of Ca2+ into the cell and is manifested by rapid collapse of the large hydrolytic vacuole and cessation of cytoplasmic streaming. This precise means of effecting cell death is a prerequ...
متن کاملMitochondrial localization and involvement in cell death
In several neurodegenerative disorders, including Alzheimer disease (AD) and Parkinson disease (PD), protein aggregation is accompanied by mitochondrial dysfunction. An increasing number of proteins found in mitochondria have multiple localizations. The Amyloid β-peptide precursor protein (APP), a key protein in AD, has a chimeric targeting signal (endoplasmic reticulum (ER) + mitochondria). AP...
متن کاملMitochondrial fission proteins regulate programmed cell death in yeast.
The possibility that single-cell organisms undergo programmed cell death has been questioned in part because they lack several key components of the mammalian cell death machinery. However, yeast encode a homolog of human Drp1, a mitochondrial fission protein that was shown previously to promote mammalian cell death and the excessive mitochondrial fragmentation characteristic of apoptotic mamma...
متن کاملTracheary Element Differentiation.
Vascular plants, which are adapted for life on land, first appeared in the late Silurian period, some 400 million years ago. Since then they have evolved to fill a diverse range of habitats all over the earth. The vascular systems of land plants are composed of specialized conducting tissues, the xylem and the phloem, which provide both a pathway for water and nutrient transport and mechanical ...
متن کاملTracheary element differentiation.
Tracheary elements (TEs) are cells in the xylem that are highly specialized for transporting water and solutes up the plant. TEs undergo a very well-defined process of differentiation that involves specification, enlargement, patterned cell wall deposition, programmed cell death and cell wall removal. This process is coordinated such that adjacent TEs are joined together to form a continuous ne...
