Seeds remain in a dormant state as long as environmental conditions are not ideal for germination. The depth of this sleep is inherited from their mother. Researchers reveal how this maternal imprint is transmitted through fragments of ‘interfering’ RNAs, which inactivate genes, and that a similar mechanism enables to transmit another imprint, that of the temperatures present during the development of the seed. This mechanism allows the seed to optimize the timing of its germination.

Sexual conflict, and sexual selection in general could conceivably turn out to be so “complicated” that, while it usually makes a difference when it occurs, it does not point in any particular direction for evolution.

Scientists decoded the genome of the popular Okinawan seaweed ‘umi-budo’ or ‘sea grapes,’ which could help ease the crop’s cultivation and address environmental issues caused by the invasive spread of related species.
