Review: Cycling in a crowd: coordination of plant cell division, growth and cell fate (Plant Cell)
Plant Science Research WeeklyUnlike animal cells, plant cells cannot migrate due to the presence of interconnected rigid cell walls, thus plant development relies on a continuous supply of new cells, (fueled by the cell cycle) to form new organs throughout their life. This excellent review by Sablowski and Gutierrez focuses on the…
Deceleration of cell cycle underpins a switch from proliferative-to-terminal division in plant stomatal lineage (bioRxiv)
Plant Science Research WeeklyPrecise cell cycle control is essential for the differentiation of specialized cell types. Stomata, essential pores for gas exchange located in the epidermis, are generated via proliferative asymmetric cell division (ACD) of a transient stem cell called a meristemoid, which will give rise to a guard…
