Subcellular localization and expression pattern analyses of Gnp4/LAX2. (A) Subcellular location of ProSuper::GFP and ProSuper::Gnp4-GFP in tobacco leaf cells. ProSuper::OST1-mcherry is a mCherry marker localized in the nucleus and cytosol (Ding et al., 2015). Scale bars are 20 μm. (B) GUS staining of various tissues of transgenic plants containing the ProGnp4::GUS construct. I, bud; II, seedling; III, root; IV, leaf; V, stem; VI, sheath; VII, glumes; and VIII, panicles at different stages. (C) qRT-PCR analysis of relative expression levels of Gnp4 in different tissues from wild-type Nipponbare. R, root; S, stem; L, leaf; SH, leaf sheath; and P, panicles at sequential lengths, where the number indicates the panicle length (cm). Data are means (±s.e.m.) (n=3 plants each with three technical repeats).
