A DE1 BINDING FACTOR 1-GLABRA2 module regulates rhamnogalacturonan I biosynthesis in Arabidopsis seed coat mucilage
The mucilage surrounding hydrated Arabidopsis thaliana seeds is a specialized extracellular matrix composed mainly of the pectic polysaccharide rhamnogalacturonan I (RG-I). Although, several genes responsible for RG-I biosynthesis have been identified, the transcriptional regulatory mechanisms contr...

TRANSPARENT TESTA GLABRA2, a trichome and seed coat development gene of Arabidopsis, encodes a WRKY transcription factor
Mutants of a new gene, TRANSPARENT TESTA GLABRA2 (TTG2), show disruptions to trichome development and to tannin and mucilage production in the seed coat. The gene was tagged by the endogenous transposon Tag1 and shown to encode a WRKY transcription factor. It is the first member of this large, plant...

Expression of PRX36, PMEI6 and SBT1.7 is controlled by complex transcription factor regulatory networks for proper seed coat mucilage extrusion
Mucilage secretory cells (MSC) form an intriguing cell layer important for seed germination. In Arabidopsis thaliana, several master transcription factors (TFs) and “actor” proteins have already been identified as key players for seed coat differentiation including epidermal cell formation, mucilage...

GLABRA2, A Common Regulator for Epidermal Cell Fate Determination and Anthocyanin Biosynthesis in Arabidopsis
Epidermal cell fate determination—including trichome initiation, root hair formation, and flavonoid and mucilage biosynthesis in Arabidopsis (Arabidopsis thaliana)—are controlled by a similar transcriptional regulatory network. In the network, it has been proposed that the MYB-bHLH-WD40 (MBW) activa...

Arabidopsis glabra2 mutant seeds deficient in mucilage biosynthesis produce more oil
Seed oil, one of the major seed storage compounds in plants, is of great economic importance for human consumption, as an industrial raw material and as a source of biofuels. Thus, improving the seed oil yield in crops is an important objective. The GLABRA2 (GL2) gene in Arabidopsis thaliana encodes...

People also ask
Is mucilage regulated downstream of GL2?
In the seed coat, the rhamnose synthase gene MUCILAGE MODIFIED4 (MUM4), which is required for seed mucilage production (Western et al. 2004; Oka et al. 2007), is known to be regulated downstream of GL2. The transcription of MUM4 is suppressed in gl2 mutant seeds during the middle stage of seed development.

Does glabra2 regulate anthocyanin biosynthesis in Arabidopsis?
A similar MBW complex regulates epidermal cell fate by activating the transcription of GLABRA2 (GL2), a homeodomain transcription factor required for trichome formation in shoots and non-hair cell formation in roots. Here we provide experimental evidence to show that GL2 also plays a role in regulating anthocyanin biosynthesis in Arabidopsis.

Do DF1 and GL2 affect mucilage biosynthesis?
DF1 and GL2 have additive effects on mucilage biosynthesis. A–F, Mucilage phenotypes of WT (A), df1-1 (B), gl2-8 (C and E), and df1-1 gl2-8 (D and F) seeds. Red arrow heads in (E) indicate the small amount of AM on gl2-8 seeds. Scale bars = 150 μm. G, Quantification of total mucilage content in WT, df1-1, gl2-8, and df1-1 gl2-8 seeds.

Does GL2 regulate trichome formation and mucilage synthesis?
GL2 positively regulates trichome formation and mucilage synthesis (Rerie et al., 1994). GL2 also positively regulates non-hair cell formation in root, and non-stomata cells formation in hypocotyl, leading to the inhibition of root hair and hypocotyl stomata formation (Di Cristina et al., 1996; Hung et al., 1998).

Is GL2 a positive regulator of mum4 in the seed coat?
Recent analysis of MUM4 promoter sequences suggests that, within the seed, MUM4 is expressed primarily in the seed coat (E. Esfandiari and G. Haughn, unpublished data, Department of Botany, University of British Columbia). These data suggest that GL2 is a positive regulator of MUM4 in the seed coat.

Does DF1 GL2 cooperate with GL2 in activating mum4 expression?
B, A proposed working model of the DF1–GL2 cooperation module in activating MUM4 expression. The binding of DF1 to GT3 box is dependent on the occupancy of GL2. Meanwhile, activation of MUM4 by GL2 requires the occupancy of DF1. C, A proposed working model of the DF1–GL2 cooperation module in activating GATL5 expression.
