Photoinhibition of X. tropicalis development, and in vivo photocontrol of MT dynamics in Danio rerio. (a, b) Xenopus embryos incubated with compounds for 1 h at the two-cell stage, before medium exchange optionally with 410 nm photoactivation. Embryos show irreversible development inhibition by in situ formed Z-SBTubA4 in lit conditions but had no effects in the dark or with a low concentration of SBTubA4P [(a) SBTubA4P at 5 μM; (b) development quantified by the ratio of major to minor embryo axis lengths, six embryos per condition, mean ± SEM]. (c) Development of D. rerio treated at the indicated stages for 24 h with SBTubA4P or control compounds under dark or pulsed lit (1 s/5 min) conditions. SBTubA4P (1 or 25 μM) causes morphological abnormalities only in the lit state, showing that it remains effective in vivo. (d, e) Reversible modulation of MT dynamics in 48 hpf zebrafish embryo (25 μM). (EB3-GFP in green, histone H2B in red). (data related to Movies S12–S16; see the Supporting Information).
