Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was ...

miRNAs are small non-coding RNAs that regulate gene expression and influence key developmental processes. In plants, these molecules are produced through a multistep biogenesis pathway involving the ...

Scientists at Umeå University have found a way to break open the protective walls of pollen grains – one of the hardest biomaterials in the world – without damaging the inside cell and its components.

And who tells the pollen what to do? A new study shows that pollen development is influenced by more than just its own blueprint. Instead, they receive crucial molecular “text messages” from maternal ...
