MITONUCLEAR PROTEIN GENES. "Collectively these data demonstrate that MRPs represent an evolutionarily conserved protein family that ties the mitochondrial ribosome and mitonuclear protein imbalance to the mitochondrial unfolded protein response, an overarching longevity pathway across many species.” http://www.nature.com/nature/journal/v497/n7450/abs/nature12188.html View in LinkedIn

EGG DOMINATED FATES. "Fate specification within the reduced gametophytes of flowering plants is also dependent on intercellular signaling. In embryo sacs, the egg, once specified via a hormone gradient, assumes a dominant role and generates signals that determine the fates of its neighbors." http://www.sciencedirect.com/science/article/pii/S1534580713000427 View in LinkedIn

EPIGENETICS AND TRANSPOSONS. "The hypothesis that transposable elements activated in the vegetative cell generate mobile siRNA that reinforces the methylation and silencing of cognate sperm transposable elements. This hypothesis is consistent with the known ability of small RNAs to move between plant cells." (siRNA = small interfering RNAs or silencing RNAs). http://www.sciencedirect.com/science/article/pii/S1534580713000427 View in LinkedIn

EPIGENETIC PROGRAMMING. "Communication between cells of both male and female gametophytes is also apparently important for preserving the integrity of gametic chromosomes by reinforcing the silencing of transposable elements in sperm and egg nuclei." http://www.sciencedirect.com/science/article/pii/S1534580713000427 View in LinkedIn

DIVERGENT DESTINIES. "Postmeiosis male and female developmental pathways diverge significantly, with events in the ovule being driven principally by hormone gradients and pollen development requiring defined phases of tapetal activity" as well as soma-germline continued collaboration. http://www.sciencedirect.com/science/article/pii/S1534580713000427 View in LinkedIn

PARASITIC TRANSPOSABLE ELEMENT "silencing and/or the establishment of a specific heterochromatin state may thus be essential for meiotic progression in multicellular eukaryotes and perhaps determine whether cells follow a sexual or apomictic developmental pathway." http://www.sciencedirect.com/science/article/pii/S1534580713000427 View in LinkedIn

EPIGENETIC INTERACTIONS. "Both male and female reproductive cell lineages undergo meiosis to generate haploid spores that divide to form gametophytes, and a large number of genes have been identified regulating meiosis in Arabidopsis, many of them homologs of yeast meiotic genes. The principal interactions currently known to take place between the soma and germ cells at this time are, however, epigenetic." http://www.sciencedirect.com/science/article/pii/S1534580713000427 View in LinkedIn

DRASTIC CHANGE OF FUNCTION.

TWO-WAY DIALOGUE. "That helper cells exert control over the reproductive cell line development is not surprising; however, evidence is accumulating that germ cells themselves regulate development of their helper populations in a complex two-way conversation, extending from the beginnings of the reproductive cell lineage in the sporophyte to the maturation of the gametes within the gametophyte." http://www.sciencedirect.com/science/article/pii/S1534580713000427 View in LinkedIn
