Early division Cells within organisms only divide when they have a certain amount of stem cell identity. Now Dutch researchers show in Development that the PLETHORA genes are turning on this stem cell identity directly after fertilisation. To keep control over their shape, organisms tightly control which cells are allowed to divide. In general thisContinue reading “Early division”

Controlled orientation
Controlled orientation Sometimes, when you are studying something in more detail, it turns out to be working a little different than you first imagined it. This is shown by American researchers in Nature for the orientation of cell divisions of root cells. The final form of an organism is the result of a whole bunchContinue reading “Controlled orientation”
Directing cell divisions
Directing cell divisions Multicellular organisms come in lots of different forms and shapes. Al coming from the same invention: RHO GTPases, proteins that give a cell its polarity. Now a team of Austrian researchers show in Current Biology that the plant specific RHO GTPase, ROP, is required for both the polarity and orientation of cellContinue reading “Directing cell divisions”
Stopping with division
Stopping with division A leaf consists out of multiple cell types. Not only is the inside, but the outside also has multiple cell types. Like trichomes and stomata. In addition, there are the so-called pavement cells, these cells cover the majority of the surface of the leaf. Under the microscope these pavement cells look likeContinue reading “Stopping with division”
