Like their nuclear counterpart, the plastid and mitochondrial genomes of plants have to be
faithfully replicated and repaired to ensure the normal functioning of the plant. Inability to …

The plastid transcription machinery can be biochemically purified at different organisational
levels as soluble RNA polymerase, transcriptionally active chromosome, or nucleoid. Recent …

Since the publication of the third edition of the Handbook of Plant and Crop Stress,
continuous discoveries in the fields of plant and crop environmental stresses and their …

Significance: For a plant to grow and develop, energy and appropriate building blocks are a
fundamental requirement. Mitochondrial respiration is a vital source for both. The delicate …

Plastid division is fundamental to the biology of plant cells. Division by binary fission entails
the coordinated assembly and constriction of four concentric rings, two internal and two …

Many genes in eukaryotes are acquisitions from the free-living antecedents of chloroplasts
and mitochondria. But there is no evolutionary 'homing device'that automatically directs the …

One solution found in evolution to increase the number of cellular functions, without
increasing the number of genes, is distribution of single gene products to more than one …

Plant seeds do not contain differentiated chloroplasts. Upon germination, the seedlings thus
need to gain photoautotrophy before storage energies are depleted. This requires the …

The major RNA polymerase activity in mature chloroplasts is a multisubunit, Escherichia coli-
like protein complex called PEP (for plastid-encoded RNA polymerase). Its subunit structure …

The genetic compartments of plant cells, nuclei, plastids and mitochondria exchange
information by anterograde (nucleus-to-organelle) and retrograde (organelle-to-nucleus) …
