Abstract:

Prof. Christine Beveridge's interest is in the control of plant development and she discovered strigolactone as the novel plant hormone that known to be involved in shoot branching. 

Shoot branching occurs due to the regulation of the outgrowth of axillary buds which are embryonic shoots in the axil of leaves. Long-distance signalling is central to this regulation and mainly involves strigolactones, cytokinins, auxin and sugars. It also appears that the growth of axillary buds from a state of very slow growth or dormancy, to sustained growth involves a number of stages during which the emerging shoots show differential sensitivity to growth stimulus and inhibition. This could be due to differences in hormone signaling and downstream responses as well as due to changes in the vasculature of the growing buds. She will present their latest unpublished findings on the interaction of signals and sugars during bud outgrowth.
