Unlike 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…

Precise 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…

In multicellular organisms, stem cells produce various cell types through asymmetric cell division (ACD), which is achieved is through polarization of cell-fate determinant proteins in the ACD progenitor cells. In Arabidopsis stomatal development, an ACD progenitor cell, the meristemoid mother cell (MMC),…

Proper organogenesis depends on the precise control of cell proliferation and differentiation. Cytokinin and auxin have emerged as key regulators of both these processes, where cytokinin promotes proliferation and synergistically with auxin fine-tunes the proliferation and differentiation rate. Years…

Protein analysis relies heavily on the production of ‘tagged’ proteins, i.e. recombinant proteins that contain both a functional peptide sequence and a peptide or chemical label (the ‘tag’). Common tags include fluorescent proteins (FPs), which make tagged proteins easier to detect, as well as…
