A variant, WCHlO5, expressing CHr in the callus, as well as in regenerated plantlets, was isolated from a cell line derived from a wild carrot plant. The plantlets regenerated from WCHIO5 are green, but do not produce normal, dissected leaves.
Leaf Blight (fungus - Alternaria dauci) Infection occurs mostly on older leaves, but younger leaves may also become infected. Leaf blight first appears as indefinite brown to black areas with pale yellow centers. Infected leaves shrivel when infection is heavy [Photo #1].

The phytotoxicity of alumina nanoparticles loaded with and without phenanthrene (Phen) was investigated by means of root elongation (RE) experiments in this study.
Axial and radial transport and the accumulation of photoassimilates in carrot taproot were studied using C-14 labelling and autoradiography. Axial transport of the C-14 labelled assimilates inside the taproot was rapid and occurred mainly in the young phloem found in rows radiating from the cambium.
Carrot (Daucus carota ) is a biennial plant: it completes its life-cycle in two growing seasons (within two years). Germination and vegetative growth take place during the first year, with food storage in underground parts of the plant for over-wintering.
