From left: Branching in Arabidopsis plants grown with high (left) or low (right) nitrate supply. Centre: Computational model of branch production for plants with low (left) or high (right) levels of the hormone strigolactone. Green indicates auxin levels, and red indicates accumulation of PIN1 auxin transporters. Right: Accumulation of the PIN1 auxin transporter (green fluorescence) in cells of stems from plants with low (top) or high (bottom) strigolactone.
