A Forward Genetic Screen Revealed the Role of POLDIP2 in Ensuring Maternal Inheritance of Mitochondrial DNA in Drosophila melanogaster
… mitochondrial DNA (mtDNA). In most animals, the inheritance of mtDNA follows a uniparental pattern, generally from the maternal side. Maternal inheritance is accomplished by mechanisms actively degrading paternal mtDNA before and after fertilisation. For many species, including *Drosophila*, fish …

Chloroplast Biotechnology in Higher Plants: Expressing Antimicrobial Genes in the Plastid Genome
… Most agronomically important species exhibit maternal inheritance of organellar genomes which eliminates the threat of transgene escape through pollen. Gene silencing is absent due to site directed, single copy insertion by homologous recombination. Foreign proteins can accumulate to high …

Sisters' curse: sexually antagonistic selection constrains the spread of a rare mitochondrial haplogroup
… species, anisogamy is also coupled with strict maternal inheritance of genetic elements in the cytoplasm, including DNA in cellular endosymbionts and mitochondria. Because males are an evolutionary dead end for mitochondria, mutations in the mitochondrial genome that are harmful or beneficial to …

Chloroplasts as bioreactors : high-yield production of active bacteriolytic protein antibiotics
… provides appropriate safety due to chloroplasts maternal inheritance. In this work, it was shown that three phage lytic enzymes (Pal, Cpl-1 and PlyGBS) could be successfully expressed at very high levels and with high stability in tobacco chloroplasts. PlyGBS expression reached an amount of …

Investigation of a kalilo plasmid in Louisiana Neurospora tetrasperma
… plasmid were also examined. Investigation of inheritance patterns through crosses demonstrated a maternal inheritance, thereby suggesting that kalilo' was located within the mitochondria. Additionally, transmission of the plasmid by asexual culturing was relatively stable. In order to …

An Analysis of Mitochondrial DNA in Rett Syndrome and Other Neurodegenerative Disorders
… changes, mitochondrial enzyme deficiencies and maternal inheritance (characteristic of mtDNA diseases). No investigation of mtDNA involvement has been previously conducted and, to date, no biological marker exists for this disorder.</p> <p>Our preliminary studies in mitochondrial myopathies …

Mutation analysis at the lipoprotein lipase gene locus in two South African kindreds
… of post-mortem material were available from LB. Maternal DNA revealed a 0-A transition at nucleotide position 1516 which results in the substitution of lysine for glutamic acid at codon 421 in exon 9 (E421K), while paternal DNA show a single polymorphism at codon 108 in exon 3 of the LPL gene. …

RNA editing and mutagenesis of the soybean (Glycine max) mitochondrial atp9 gene
… of the proteins involved in organellar function. Maternal inheritance of some traits such as cytoplasmic male sterility (cms) in plants can be linked to mitochondrial DNA. However, further understanding of mitochondrial gene expression, regulation and DNA rearrangements has been hindered by the …

Expression Of Cholera Toxin B Subunit-rotavirus Nsp4 Enterotoxin Fusion Protein In Transgenic Chloroplasts
… transgene expression, transgene containment via maternal inheritance, lack of gene silencing and position effect due to site specific gene integration and also the possibility of multi gene engineering in single transformation event. It is also an environmentally friendly approach due to …

Identifikasi pola haplotipe DNA mitokondria udang jari (Metapenaeus elegans) Segara Anakan Kabupaten Cilacap Jawa Tengah menggunakan enzim restriksi HindIII
… enzyme HindIII. Mitochondrial DNA is only maternal inheritance and has a high variation. Restriction enzyme HindIII used in Klinbunga research (1998) and digested many fragments in penaeidae shrimp. This study aims to find out the number and size of the fragment which is digested by …

Genetic analysis of grain protein concentration and related traits in the Illinois protein strain recombinant inbred population of maize
… zein protein concentrations are subject to the maternal effect, where the progeny phenotype follows that of the maternal plant. This phenomenon has been observed in a variety of maize genotypes, including IHP and ILP, but its source is unknown. A series of genetic resources derived from the …
