Sucrose Metabolism in Plastids [PDF]
Plant Physiology, 2001 Abstract The question whether sucrose (Suc) is present inside plastids has been long debated. Low Suc levels were reported to be present inside isolated chloroplasts, but these were argued to be artifacts of the isolation procedures used.

Plastids and mitochondria comportment in dividing meiocytes of Psilotum nudum
Acta Societatis Botanicorum Poloniae, 2014 In prophase I meiocyte plastids and mitochondria were situated at random. By telophase I plastids and mitochondria were aggregated in an equatorial plane.

The chloroplast min system functions differentially in two specific nongreen plastids in Arabidopsis thaliana. [PDF]
PLoS ONE, 2013 The nongreen plastids, such as etioplasts, chromoplasts, etc., as well as chloroplasts, are all derived from proplastids in the meristem. To date, the Min system members in plants have been identified as regulators of FtsZ-ring placement, which are ...

Eco-Evolutionary Perspectives on Mixoplankton
Frontiers in Marine Science, 2021 Mixotrophy, i.e., the capability of both phototrophy and phagotrophy within a single organism, is a prominent trophic mode in aquatic ecosystems. Mixotrophic strategies can be highly advantageous when feeding or photosynthesis alone does not sustain ...
