In addition, we compared the induction of BGLU23 and TGG1 by Mn deficiency in roots with the expression changes in leaves via qRT-PCR.
Expression of three caleosin members (Clo5, Clo7, and Clo9) were detected in rye root tissue, with the expression of Clo9 being dominant, and Clo5 and Clo7 detected at very low levels.
Although only ten genes were tested, estimation of transcript abundance by EST frequency was apparently effective in identifying genes with root-specific expression, despite the majority of root ESTs coming from a normalized library source.
Young roots with root hairs showed expression of the sesquiterpene synthase genes as well.
In this study, the reverse transcriptase polymerase chain reaction was used to identify seven genes with root-specific expression in rice.
Among these, Unigene4318_All and Unigene529_All showed high-level expression levels in mycorrhizal roots with little expression in the un-inoculated control and ZH3A-3 treatments.
Moreover, GhWRKY15 transcription was greater in the roots and stems compared with the expression in the cotyledon of cotton, and the stems of transgenic plants displayed faster elongation at the earlier shooting stages compared with wide type tobacco.
OsGLR2.1 was expressed most highly in the root, with moderate expression in shoot, stem-base and young panicle tissues, and almost no expression in the stem.
Voiced by the directors in babbling helium-fuelled goobledegook, these yellow weebles are comedy gold, their slapstick antics blending a simplicity of form with a complexity of expression rooted in the traditions of silent cinema.
AtOCD promoter activity was low in unstressed plants with some expression in root and localized expression in the shoot meristem and developing leaf tissue.
The genes in the QTL interval region for root thickness of 0.5 1.0 mm (Glyma08g19050 ) and taproot length (Glyma15g42220 ) showed higher expression in RILs with roots smaller than the G. soja parent.
