Fig. 5From: Sucrose accumulation in sweet sorghum stems occurs by apoplasmic phloem unloading and does not involve differential Sucrose transporter expressionCF localization in stems of Macia and Wray plants fed CFDA from a source leaf. CF localized to the phloem tissue in the stem vasculature of Macia (a) and Wray (b). Control section from a Macia plant not fed CFDA (c). Only weak autofluorescence was detected. UV images of same sections to show cellular anatomy (d-f). Scale bar = 100 μmBack to article page
