Shikonin derivatives are specialized lipophilic metabolites, secreted in abundant amounts from the root epidermal cells of Lithospermum erythrorhizon. Because they have anti-microbial activities, these compounds, which are derivatives of red naphthoquinone, are thought to serve as a chemical barrier for plant roots. The mechanism by which they are secreted from cells is, however, largely unknown.

Metrics details. Through evolution, some plants have developed natural resistance to insects by having hairs trichomes on leaves and other tissues. The hairy trait has been neglected in Brassica breeding programs, which mainly focus on disease resistance, yield, and overall crop productivity.
Hairy cell leukemia is an uncommon hematological malignancy characterized by an accumulation of abnormal B lymphocytes. Hairy cell leukemia was originally described as histiocytic leukemia, malignant reticulosis, or lymphoid myelofibrosis in publications dating back to the s. The disease was formally named leukemic reticuloendotheliosis and its characterization significantly advanced by Bertha Bouroncle and colleagues at The Ohio State University College of Medicine in
Why is it advantageous to be a hairy caterpillar? One answer can be found in a beautiful paper by Sugiura and Yamazaki They put five species of caterpillars with various amounts of hairiness in containers with carabid beetles that naturally prey on caterpillars.

This book provides the latest information about hairy root culture and its several applications, with special emphasis on potential of hairy roots for the production of bioactive compounds. Due to high growth rate as well as biochemical and genetic stability, it is possible to study the metabolic pathways related to production of bioactive compounds using hairy root culture. Chapters discuss the feasibility of hairy roots for plant derived natural compounds. Advantages and difficulties of hairy roots for up-scaling studies in bioreactors are included as well as successful examples of hairy root culture of plant species producing bioactive compounds used in food, flavors and pharmaceutical industry.
