The regulation of genes involved in trichome development
… by a complex of genes including GLABRA1 (GL1), TRANSPARENT TESTA GLABRA (TTG), and GLABRA3 (GL3). This work examines the role of GL3 in trichome initiation and uses plants expressing varying levels of GL3 to determine if genes involved in trichome development are regulated by GL3. Though several …

Molecular and Biochemical Genetics of 2-Oxoglutarate-Dependent Dioxygenases Required for Flavonoid Biosynthesis in Arabidopsis thaliana
… whether any of the previously-identified transparent testa mutants were defective in F3H, FLS, or LDOX, the chromosomal locations of these genes in the Arabidopsis genome were determined. The positions of these genes suggested that no previously-identified tt mutant was defective in the …

Analysis of two single trait loci affecting flavonol glycoside accumulations in Arabidopsis thaliana natural variations
… 5 at 99 cM. The previously characterized TRANSPARENT TESTA 10 was identified to encode the Qr4 locus when comparing quercitrin accumulation between mutants and wildtypes (WTs) seed coats. Allelic difference in the TT10 promoter sequence in Ler was identified to cause lower promoter …

Identification and analysis of genes involved in cotton fibre initiation.
… One gene essential for trichome initiation is TRANSPARENT TESTA GLABRAI (TTGI), and loss-of-function mutations in TTGI result in an almost complete absence of leaf trichomes. TTG 1 plays additional roles in numerous pathways in Arabidopsis, including root hair initiation, anthocyanin production …

Identification of novel components of the zinc homeostasis mechanism in Arabidopsis thaliana
… different flavonoids deficient mutants (i.e. transparent testa (tt) mutants). The mutant line that is completely devoid of flavonoids (tt4) and the one lacking quercetin (tt7) showed strong zinc hypersensitivity. Thus, quercetin appeared to be more effective than kaempferol in shielding the …

Understanding the molecular mechanism of postharvest seed coat darkening in pinto beans
Pinto bean (Phaseolus vulgaris) is one of the leading market classes of dry beans that is affected by postharvest seed coat darkening. Bean producers and vendors encounter significant crop value loss due to the decreased consumer preference for the darker beans. Darker beans also display poor …
