The TRANSPARENT TESTA16 locus encodes the ARABIDOPSIS BSISTER MADS domain protein and is required for proper development and pigmentation of the seed coat

Screening for seed pigmentation phenotypes in Arabidopsis led to the isolation of three allelic yellow-seeded mutants, which defined the novel TRANSPARENT TESTA 16 (TT16) locus. Cloning of TT16 was performed by T-DNA tagging and confirmed by genetic complementation and sequencing of two mutant alleles. TT16 encodes the ARABIDOPSIS BSISTER (ABS) MADS domain protein. ABS belongs to the recently identified "B-sister" (B^sub S^) clade, which contains genes of unknown function that are expressed m...

SEED COATS: STRUCTURE, DEVELOPMENT, COMPOSITION, AND BIOTECHNOLOGY
In Vitro Cellular & Developmental Biology ; SUMMARY Although seeds have been the subject of extensive studies for many years, their seed coats are just beginning to be examined from the perspective of molecular genetics and control of development. The seed coat plays a vital role in the life cycle of plants by controlling the development of
MUCILAGE-MODIFIED4 Encodes a Putative Pectin Biosynthetic Enzyme Developmentally Regulated by APETALA2, TRANSPARENT TESTA GLABRA1, and GLABRA2 in the Arabidopsis Seed Coat1
Plant Physiology ; The Arabidopsis seed coat epidermis undergoes a complex process of differentiation that includes the biosynthesis and secretion of large quantities of pectinaceous mucilage, cytoplasmic rearrangement, and secondary cell wall biosynthesis. Mutations in MUM4 (MUCILAGE-MODIFIED4) lead to a decrease in

Chemical structural investigation of the cotton fiber base and associated seed coat: Fourier-transform infrared mapping and histochemistry
Textile Research Journal ; ABSTRACT Fourier-transform mid-infrared mapping and histochemical staining are used to reveal the location and relative importance of chemical components involved with the base of cotton fibers and their associated seed coat. These two complementary techniques are focused on the nature of the

The Botanical Review ; II. Introduction Seeds are fundamentally important to people, not only because they constitute the chief method of plant propagation, but also because they provide an important food (Duffus & Slaughter, 1980).

MYB61 is required for mucilage deposition and extrusion in the Arabidopsis seed coat
Plant Cell ; We have undertaken a systematic reverse genetic approach to understand R2R3-MYB gene function in Arabidopsis. Here, we report the functional characterization of MYB61 based on the phenotype of three independent insertion alleles. Wide-ranging phenotype screens indicated that MYB61 mutants were
Patterning of Virus-Infected Glycine max Seed Coat Is Associated with Suppression of Endogenous Silencing of Chalcone Synthase Genes
Plant Cell ; Most commercial Glycine max (soybean) varieties have yellow seeds because of loss of pigmentation in the seed coat. It has been suggested that inhibition of seed coat pigmentation in yellow G. max may be controlled by homology-dependent silencing of chalcone synthase (CHS) genes. Our analysis of
