Rice EL5 is an ATL family gene characterized by a transmembrane domain at the N-terminal and a RING-H2 finger domain (RFD), which exhibits ubiquitin ligase (E3) activity.

Annotated Information

Function

Rice EL5 is an ATL family gene characterized by a transmembrane domain at the N-terminal and a RING-H2 finger domain (RFD), which exhibits ubiquitin ligase (E3) activity. Overexpression of mutated EL5 gene arrests root growth in an E3-activity-dependent manner.Transgenic callus overexpressing mutated EL5 gene is morphologically auxin-irresponsive and similar to control callus treated with excess cytokinin.

'Figure 4. Overexpression of mutated EL5 alters responses to auxin and cytokinin during regeneration. (a) Effects of auxin and cytokinin on the differentiation of callus cells. Calli transformed with only vector as control (left) and EL5W165A (right) were cultured on the regeneration medium with different a-naphthalene acetic acid and kinetin contents. The numbers of calli regenerating shoot with root (white bars), root only (gray bars), and shoot only (black bars) are presented as percentages of the total numbers of calli placed on the medium. The total numbers of calli counted are indicated in parenthesis. The average scores from two independent lines are plotted. The examination was repeated three times and typical results are shown.(b) Representative phenotypes of the regenerating calli described in (a).'
