Figure 5: UbL401 and UbL404 mRNAs preferentially express in MMCs.
From: RNase ZS1 processes UbL40 mRNAs and controls thermosensitive genic male sterility in rice

(a,b) In situ hybridization of UbL401 (a) and UbL404 (b) transcripts in anther. (c,d) At indicated temperatures, expression level of UbL404 in MMCs under high (28 °C) and low (23 °C) temperature in AnN (c) and AnS-1 (d). Scale bars, 10 μm (a,b). MMC, microspore mother cells.
