Plant Organelles

The plant organelles database (PODB): a collection of visualized plant organelles and protocols for plant organelle research

The plant organelles database (PODB; http://podb.nibb.ac.jp/Organellome) was built to promote a comprehensive understanding of organelle dynamics, including organelle function, biogenesis, differentiation, movement and interactions with other organelles. This database consists of three individual parts, the organellome database, the functional analysis database and external links to other datab...

Plant and animal organelles in cell death

Programmed cell death (PCD) is a finely regulated and genetically controlled process which plays crucial roles in various biological courses. In human, inappropriate PCD could lead to various diseases including neurodegenerative diseases, ischemic damage, autoimmune disorders, and many types of cancers [1]. Over decades, great efforts have been made in identifying key cell death genes in variou...

RNA Editing and Its Molecular Mechanism in Plant Organelles

RNA editing by cytidine (C) to uridine (U) conversions is widespread in plant mitochondria and chloroplasts. In some plant taxa, "reverse" U-to-C editing also occurs. However, to date, no instance of RNA editing has yet been reported in green algae and the complex thalloid liverworts. RNA editing may have evolved in early land plants 450 million years ago. However, in some plant species, includ...

Prediction of dual protein targeting to plant organelles.

* Dual targeting of proteins to more than one subcellular localization has been found in animals, in fungi and in plants. In the latter, ambiguous N-terminal targeting signals have been described that result in the protein being located in both mitochondria and plastids. We have developed ambiguous targeting predictor (ATP), a machine-learning implementation that classifies such ambiguous targe...
