A plant that has the mutant form of the WEREWOLF gene (wer) would be identifiable by
A. the excessive number of vascular bundles in stem.
B. the lack of fibers in the outer portions of the stem.
C. the abundance of microscopic hairs on the root.
D. the extra thick layer of mesophyll cells in the leaf.
E. the lack of microscopic hairs along the epidermis of the root.
C. the abundance of microscopic hairs on the root.
The WEREWOLF gene (WER) inhibits root hair development in root epidermal cells. In contrast, the mutant form of the gene (wer) facilitates the development of root hairs. See section 36.3 for a more detailed explanation of the WEREWOLF gene.
