Can the chloroplast division machinery be evolutionarily dated back to bacteria?

The chloroplast, known to have originated around a billion years ago, is now one of the most recognizable characteristics of the plant cell. After the engulfment of the ancient cyanobacterium by the eukaryotic host cell, the former

Chloroplast movements after blue light pulses give new insights into the photoreceptor functioning

Plants rely on light as a source of energy. The availability of light is often a limiting factor for the process of photosynthesis. However, too much light can cause cell damage. Plants have numerous mechanisms of adjusting

Advancing medicine and agriculture using proteins that control energy and sugar production

Except for bacteria , most living organisms contain specialized cellular compartments termed mitochondria , that are responsible for breaking down sugars to produce energy for the cell. Plant cells possess a second compartment called chloroplasts , which

Stress tolerance in plants is controlled by a “master regulator” of chloroplast protein import

To achieve food security by meeting the needs of an ever growing human population, which could reach near 10 billion by 2050, large increases in crop yields will be essential. Environmental stresses, such as drought and salinity,
