Title

Effects of Reduced Chloroplast Gene Copy Number on Chloroplast Gene Expression in Maize

Dylan B. Udy; Susan Belcher; Rosalind Williams-Carrier; et al. PLANT PHYSIOLOGY 2012. doi:10.1104/pp.112.204198

Other claims from this paper (10)

Intervention effect Weak w2 alleles reduced maize plastid DNA copy number about fivefold.
Intervention effect Strong w2 alleles reduced maize plastid DNA copy number about 100-fold.
Association Some chloroplast RNAs were more sensitive to genome copy number reduction than others.
Intervention effect rpoB mRNA accumulated to dramatically elevated levels after a moderate plastid DNA reduction.
Intervention effect Photosynthetic enzyme subunits were reduced more severely than plastid mRNAs.
Mechanism The authors suggest impaired translation from limiting ribosomal RNA, transfer RNA and ribosomal protein mRNA could explain the enzyme subunit reduction.
Mechanism The authors conclude that chloroplast genome copy number limits expression of a subset of chloroplast genes.
Mechanism w2 is responsible for virtually all chloroplast DNA replication in maize.
Intervention effect Strong w2 alleles reduced mitochondrial DNA copy number approximately twofold.
Mechanism The mitochondrial DNA result suggests that w2 contributes to mitochondrial DNA replication.
