Abstract

Editorial: Physiology and Cellular Mechanisms of Isothiocyanates and Other Glucosinolate Degradation Products in Plants.

Highlights

  • Isothiocyanates (ITCs), thiocyanates, and epithionitriles are produced enzymatically from sulfurcontaining glucosinolates (GLS) by β-thioglucosidases called myrosinases (Bones and Rossiter, 2006), whilst there is growing evidence that they have multiple roles in host plants

  • The role of ITCs in plant defense against pests and pathogens has been thoroughly described and multiple roles and functions for GLSs and their derived products suggested. These amongst others include a role as allelochemicals and in sulfur storage, water transport, heat tolerance, stomatal regulation, apoptosis, growth inhibition, and signaling

  • A knowledge of the GLSs, their tissue and cellular localization and metabolism under various environmental conditions is important in the assessment of potential physiological effects

Summary

Introduction

Isothiocyanates (ITCs), thiocyanates, and epithionitriles are produced enzymatically from sulfurcontaining glucosinolates (GLS) by β-thioglucosidases (thioglucoside glucohydrolase EC 3.2.3.147) called myrosinases (Bones and Rossiter, 2006), whilst there is growing evidence that they have multiple roles in host plants. The role of ITCs in plant defense against pests and pathogens has been thoroughly described and multiple roles and functions for GLSs and their derived products suggested. There are many thousands of papers on the cellular effects of ITCs when used in microbial and animal/human cell studies.
