Abstract

<p>(a) Pollen tube loaded with fluo-4/AM without La<sup>3+</sup> (control). Pollen tubes after loading with fluo-4/AM followed by the addition of 10 μM La<sup>3+</sup> (b), 100 μM La<sup>3+</sup> (c), and 1 mM La<sup>3+</sup> (d). (e) Pollen tube after loading with fluo-4/AM in the presence of 1 mM La<sup>3+</sup>. Scale bars: 100 μm (a), 90 μm (b and c), 60 μm (d) and 70 μm (e).</p
