Long lasting effects of cell divisions Lots of organisms show one or more forms of symmetry, plants included. In The Plant Journal English researchers show that this symmetry starts by cel divisions. Because of their cell wall plant cells can not move from their location. Therefore how and when a cell divides in part influencesContinue reading “Long lasting effects of cell divisions”

Early division
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”
