Meiotic recombination assures genetic variation during breeding. During meiotic prophase I, chromosomes are organized in a loop-base array by a proteinaceous structure called meiotic chromosome axis ...

A common lab plant that’s been poked and put under microscopes for decades may seem unlikely to keep secrets. But in widely studied Arabidopsis thaliana, scientists have identified the “cantil” — a ...

What makes plants grow to a certain size? From the tiniest cells to whole leaves, roots, and stems, growth has to be carefully coordinated—but until now, it has been hard to compare findings from ...

Plant stem cells are crucial for the world's food supply, animal feed, and fuel production. They lay the foundation for how plants grow. Yet, much about these mysterious building blocks remains ...

One of the most fascinating discoveries in biology is that cells have mechanisms for dynamically regulating genetic expression. This ability to promote or restrict the transcription of specific genes ...

Arabidopsis thaliana shoot apical meristem with multiple flowers radiating out from centre at different stages of development (left) and the shoot apex under a scanning electron microscope where the ...
