    ..Because Polycomb group proteins control parental imprinting in mammals as well, the independent recruitment of similar protein machineries for the imprinting of genes is a notable example of convergent evolution. ..

    ..The results show that plastid mRNA stability is effectively controlled by the regulation of a specific dark-induced RNA degradation pathway. ..

    ..This program includes not only responses to oxidative stress, but also responses known to be activated during plant-pathogen interactions and wounding. ..

    ..Thus, FIS-mediated expression patterns established in the female gametophyte can impact on seed development, establishing fis mutants as true female gametophytic maternal-effect mutants. ..

    ..Consistent with this idea, the constitutive shade-avoidance phenotype of phyB mutants partially reverts in the absence of PIF4 and PIF5. ..
