Abstract:
Chalcone synthase (CHS) catalyzes the first and key regulatory step in flavonoid biosynthesis. We report the existence and characterization of a CHS multigene family present in Trifolium subterraneum L. cultivar Karridale. The CHS family consists of at least four members, which are tightly clustered in a 15-kb region. The complete sequences of two of these genes (CHS1 and CHS2) are presented. The putative promoters of these genes have sequences which are homologous to those known, or implicated, in regulation of the expression of phenylpropanoid-encoding genes.

Protein Transport to the Stroma
Protein complexes called the translocon of the outer chloroplast membrane or TOC complex, and the translocon of the inner chloroplast membrane or TIC complex mediate the...
Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
