Figure 9: Expression patterns of PTB1.
From: Natural variation in PTB1 regulates rice seed setting rate by controlling pollen tube growth
(a–h) GUS activity in various organs of PPTB1-GUS-transformed rice plants. (a) Growing root, (b) stem node, (c) stem internode, (d) leaf, (e) floret, (f) pistil, (g) shell of unpollinated spikelet and (h) pollen grains. (i) Relative PTB1 transcript levels of several tissues detected by q-PCR analysis. DAP, days after pollination. Values represent the mean±s.e.m. (n=3). Scale bars, 400 μm in (a), 3 mm in (b) and (c), 1 cm in (d), 1 mm in (e) and (f), 4 mm in (g) and 50 μm in (h).
