Genome-wide analysis of Arabidopsis pentatricopeptide repeat proteins reveals their essential role in organelle biogenesis.
The complete sequence of the Arabidopsis thaliana genome revealed thousands of previously unsuspected genes, many of which cannot be ascribed even putative functions. One of the largest and most enigmatic gene families discovered in this way is characterized by tandem arrays of pentatricopeptide repeats (PPRs). We describe a detailed bioinformatic analysis of 441 members of the Arabidopsis PPR ...
متن کاملFormation of the Arabidopsis pentatricopeptide repeat family.
In Arabidopsis (Arabidopsis thaliana) the 466 pentatricopeptide repeat (PPR) proteins are putative RNA-binding proteins with essential roles in organelles. Roughly half of the PPR proteins form the plant combinatorial and modular protein (PCMP) subfamily, which is land-plant specific. PCMPs exhibit a large and variable tandem repeat of a standard pattern of three PPR variant motifs. The associa...
متن کاملThe pentatricopeptide repeat (PPR) gene family, a tremendous resource for plant phylogenetic studies.
* Despite the paramount importance of nuclear gene data in plant phylogenetics, the search for candidate loci is believed to be challenging and time-consuming. Here we report that the pentatricopeptide repeat (PPR) gene family, containing hundreds of members in plant genomes, holds tremendous potential as nuclear gene markers. * We compiled a list of 127 PPR loci that are all intronless and hav...
متن کاملIsolation and molecular characterization of the RecQsim gene in Arabidopsis, rice (Oryza sativa) and rape (Brassica napus)
In any organism that reproduces sexually, DNA Recombination plays vital roles in the generation of allelic diversity as well as in preservation of genome fidelity. Genome fidelity is particularly important in plants because mutations occurring during the development of flowering plants are heritable and can be passed onto the next generation. One of the gene families that play crucial roles in ...
متن کاملIdentification of the fertility restoration locus, Rfo, in radish, as a member of the pentatricopeptide-repeat protein family.
Ogura cytoplasmic male sterility (CMS) in radish (Raphanus sativus) is caused by an aberrant mitochondrial gene, Orf138, that prevents the production of functional pollen without affecting female fertility. Rfo, a nuclear gene that restores male fertility, alters the expression of Orf138 at the post-transcriptional level. The Ogura CMS/Rfo two-component system is a useful model for investigatin...
