Introduction Conflict often leads to nonequilibrium fluctuations as attackers spread, host defences increase, and counter-attack evolves. Spatial processes play a crucial role when attack types arrive from other populations and import of matching defence follows. We focus on cytoplasmic male sterility (CMS), an ideal system in which to study the spatial dynamics of conflict. Cytoplasmically inh...

Known in over 150 species, cytoplasmic male sterility is encoded by aberrant mitochondrial genes that prevent pollen development. The RNA- or protein-level expression of most of the mitochondrial genes encoding cytoplasmic male sterility is altered in the presence of one or more nuclear genes called restorers of fertility that suppress the male-sterile phenotype. Cytoplasmic male sterility/rest...

ENETIC cytoplasmic male sterility in Sorghum is fundamentally an aspect of the problem of gene action and nuclear-cytoplasmic interaction. Our interest in the problem stems not from a concern with the practical use so effectively being made of the failure of certain lines to produce functional pollen but rather from a desire to know more about the basic components of this process as an example ...
