Shoot branching is a highly plastic developmental process in which axillary buds are formed
in the axil of each leaf and may subsequently be activated to give branches. Three classes …

Shoot branching is inhibited by auxin transported down the stem from the shoot apex. Auxin
does not accumulate in inhibited buds and so must act indirectly. We show that mutations in …

… Apparently, I have been writing reviews about auxin for 20 years (Leyser, 1997), and certainly
I have been in very good company. Auxin is a much-written-about molecule. Entire books are …

Despite 100 years of evidence showing a pivotal role for indole-3-acetic acid (IAA or auxin)
in plant development, the mechanism of auxin perception has remained elusive. Central to …

… Ottoline Leyser … & Leyser, O. Changes in auxin response from mutations in an AUX/IAA
gene. Science 279, 1371–1373 (1998). … Ottoline Leyser …

Root formation in plants involves the continuous interpretation of positional cues. Physiological
studies have linked root formation to auxins. An auxin response element displays a …

Background: Plant development is exquisitely environmentally sensitive, with plant hormones
acting as long-range signals that integrate developmental, genetic, and environmental …

The plant shoot body plan is highly variable, depending on the degree of branching.
Characterization of the max1–max4 mutants of Arabidopsis demonstrates that branching is …

Background Plants achieve remarkable plasticity in shoot system architecture by regulating
the activity of secondary shoot meristems, laid down in the axil of each leaf. Axillary meristem …

Background It has been known for many decades that auxin inhibits the activation of axillary
buds, and hence shoot branching, while cytokinin has the opposite effect. However, the …
