Purple Stem, Hairy

Purple Stem, Hairy

Phenotype: purple stems
Genotype: ANL/ANL

Purple Stem, Hairy is a true-breeding Fast Plants stock that is homozygous dominant for a gene that regulates expression of the purple pigment, anthocyanin. This stock displays purple coloration in stem (most evident in the hypocotyl), leaves, and buds. Note that purple intensity is also influenced by light intensity. Hairs known as trichomes are found in varying numbers, mostly on the stem and leaves of this stock.

Investigations

  • Inheritance studies involving purple pigment (anthocyanin) production and expression in crosses with Non-Purple Stem variety (anl/anl)
  • Investigating the inheritance of leaf hairs (trichomes)
