(chromoplast and chloroplast) or lesser (proplastid and amyloplast) complexity; a complete prokaryotic-like genetic machinery consisting of organellar DNA, transcription factors and ribosomes; and division by fission (again, very prokaryotic-like) (Miyagishima and Kuroiwa, 2006). Unlike mitochondria,...
Like mitochondria, chloroplasts can be either inherited from both or only one parent, depending on the size of the gametes and mechanisms that specifically eliminate chloroplast DNA from one parent.

The genusVacciniumL. (family Ericaceae) comprises more than 450 species of wide geographic distribution, occurring mostly in the Northern Hemisphere and in mountainous regions of tropical Asia, Central and South America. With a few exceptions, most of the berry fruits produced by the genus are edi...
Deficiency in MOSAIC DEATH 1 (MOD1), a plastid-localized enoyl-ACP reductase, leads to the accumulation of reactive oxygen species (ROS) and PCD, which can be suppressed by mitochondrial complex I mutations, indicating a signal from chloroplasts to mitochondria. However, this signal remains to ...
This paper focusses on the siphonous marine green algaeBryopsisandTydemania, two members of the order Bryopsidales [20]. Species in this order form thalli that are composed of a single, giant cell, containing millions of nuclei, chloroplasts and mitochondria that move about freely by cytoplasmic...
Chloroplasts have an active role in the induction and course of senescence through signals, derived from reactive oxygen species (ROS), exiting to the cytosol. In this way, leaf chloroplasts mimic the role of mitochondria in the apoptosis of non-photosynthetic organs. Oxylipins, magnesium-...
GPx6 (At4g11600) is suggested to be alternatively targeted to mitochondria and the cytosol, while GPx1 (At2g25080) and Gpx7 (At4g31870) are chloroplast-targeted and protect plants from photooxidative stress [22]. The conserved exonintron-structure strongly indicates a common origin of GPx1 ...
on theplastidsystem ofEuglenaas an example, what I will have to say is at least qualitatively true for mitochondria and for chloroplasts of other species. Threerecent symposia collect a great deal of our current knowledge of the development and inheritance of chloroplasts and mitochondria and the ...
As other ingested prey organelles such as nuclei and mitochondria are lost or digested, the chloroplast may be retained, and this might ultimately result in a chloroplast with three membranes (two original plastid membranes and one that remains from the food vacuole). One difficulty in ...
