Uniparental inheritance of mitochondrial and chloroplast genes: mechanisms and evolution.
In nearly all eukaryotes, at least some individuals inherit mitochondrial and chloroplast genes from only one parent. There is no single mechanism of uniparental inheritance: organelle gene inheritance is blocked by a variety of mechanisms and at different stages of reproduction in different species. Frequent changes in the pattern of organelle gene inheritance during evolution suggest that it ...
متن کاملUniparental inheritance of organelle genes
the remarkable and varied molecular and cellular mechanisms that produce these patterns. I will also consider the evolutionary consequences of uniparental inheritance and some of the proposed evolutionary explanations for this remarkable difference between the inheritance of organelle and nuclear genes. Patterns and mechanisms of uniparental inheritance vary widely Correns studied the four-o'cl...
متن کاملUniparental Inheritance of Chloroplast DNA Is Strict in the Isogamous Volvocalean Gonium
BACKGROUND A problem has remained unresolved regarding the exceptions to the unilateral inheritance of chloroplast DNA (cpDNA) from MT+/female in Chlamydomonas and other volvocaleans demonstrated by the previous genetic analyses. For identification of the parental types of cpDNA, these studies used parents that have differences in restriction fragment length polymorphisms and exhibit partial se...
متن کاملSequence of a Brassica campestris myrosinase gene.
Myrosinase (thioglucoside glucohydrolase, P-thioglucosidase, EC 3.2.3.1) catalyzes the hydrolysis of glucosinolates, a diverse group of sulfur-containing glycosides that are present in a11 the Cruciferae, to D-G~c, sulfur, and a variety of volatile compounds including thiocyanates, isothiocyanates, and nitriles (Fenwick et al., 1983). Normally, myrosinase and the glucosinolates are kept sequest...
متن کاملInduction of Hydrolytic Enzymes in Brassica campestris in Response to Pathovars of Xanthomonas campestris.
Inoculation of mature leaves of turnip (Brassica campestris) with the incompatible Xanthomonas campestris pv vitians resulted in the induction of beta-1,3-glucanase and chitinase/lysozyme (CHL) activity. No increase in the basal activity of beta-1,3-glucanase was observed after inoculation of leaves with heat- or rifampicin-killed X. c. vitians, Escherichia coli, or sterile water. Inoculation w...
