Highlights of plant science 2017. Nov-Dec

The last week of the year is the time to look back and reflect. We like to take this opportunity to recognize the good work done by the plant science community. During this final week of 2017 we've been reminding you of some of the big stories and successes that came from our community. These stories…

Axis of Algae: Disruption of Basal Cell Fates in the Brown Alga Ectocarpus

Polarization may be bad for civil discourse, but sometimes polarization can be good—for example, if you’re a multicellular organism setting its body axes. In many organisms, polarity within the zygote sets the stage for an asymmetric cell division that defines the apical-basal polarity of the developing…

Stochastic gene expression in Arabidopsis thaliana

Biology is a noisy act, as the expression of the same gene in the cells of the same tissue differs. This noise can be divided into intrinsic noise, due to inherent stochasticity of molecular processes, and extrinsic noise, indicating differences between the neighboring cells. Schultheiß Araújo and…
