In Arabidopsis , the monopteros gene regulates:

A) positional effects in leaves.
B) the activity of the vascular cambium.
C) the differentiation of wounded parenchyma cells into tracheids.
D) apical-basal pattern formation.
E) the location of the preprophase band.

Arabidopsis

A small flowering plant used extensively in the study of genetics, molecular biology, and plant sciences due to its relatively simple genome and short life cycle.

Monopteros Gene

A gene in Arabidopsis thaliana that plays a crucial role in the development of the root apical meristem and axial pattern formation.

Vascular Cambium

A layer of plant tissue located between the xylem and the phloem in the stems and roots of vascular plants, responsible for secondary growth.
