Student life - A playful way to learn.

Students do not always like speaking in class. The more confident talkers can sometimes overshadow more reserved students, who prefer to let others talk while they think things through.

Cell specification in the Arabidopsis root epidermis requires the activity of ECTOPIC ROOT HAIR 3--a katanin-p60 protein.

The Arabidopsis root is composed of radial cell layers, each with distinct identities. The epidermal layer is composed of rows of hair cells flanked on either side by rows of non-hair epidermal cells. The development of hair and non-hair cells is dependent on domains of positional information with strict boundaries.
