Non-Purple Stem, Yellow-Green Leaf

Phenotype: lacks purple coloration and has yellow-green leaves
Genotype: anl/anl, ygr/ygr

Non-Purple Stem, Yellow-Green Leaf is a true-breeding Fast Plants stock that is homozygous recessive for two genes that are inherited independently: a gene that inhibits expression of the purple pigment anthocyanin, and a gene that causes cotyledons, leaves, stems, and developing pods to have a light yellow-green color (as compared to the darker green of Standard Fast Plants). This stock shows no purple coloration in stems, leaves, or any plant parts.

Investigations
