Hairless but no longer clueless: understanding glandular trichome development
نویسندگان
چکیده
Glandular trichomes are remarkable biochemical factories that produce a wealth of secondary metabolites important for plant defenses against herbivores. However, little is known about their developmental biology. Studying the tomato hairless mutant, which develops distorted glandular trichomes and has compromised metabolic and defense capacity, Kang et al. (pages 5313–5324 in this issue) showed that the SRA1 gene regulates not only trichome morphogenesis, but also aspects of secondary metabolism.

Distortion of trichome morphology by the hairless mutation of tomato affects leaf surface chemistry
Trichomes are specialized epidermal structures that function as physical and chemical deterrents against arthropod herbivores. Aerial tissues of cultivated tomato (Solanum lycopersicum) are populated by several morphologically distinct trichome types, the most abundant of which is the type VI glandular trichome that produces various specialized metabolites. Here, the effect of the hairless (hl)...

The Colorado potato beetle, Leptinotarsa decemlineata Say, is the major insect pest of potato, Solanum tuberosum L., in eastern North America and is renowned for resistance development, currently resistant to >40 insecticides worldwide. Host plant resistance may assist in delaying in resistance development to insecticides. We evaluated natural host plant resistance mechanisms (glandular trichom...
متن کاملDevelopmental plasticity of glandular trichomes into somatic embryogenesis in Tilia amurensis.
BACKGROUND AND AIMS In Tilia amurensis, two types of trichomes (hairy and glandular) develop from epidermal surfaces of cotyledons and hypocotyls of zygotic embryos soon after germination. Here, it is demonstrated that glandular trichome initials develop directly into somatic embryos when treated in vitro with 2,4-dichlorophenoxyacetic acid (2,4-D). METHODS Zygotic embryos of Tilia amurensis ...
متن کاملGlandular trichomes: what comes after expressed sequence tags?
Glandular trichomes cover the surface of many plant species. They exhibit tremendous diversity, be it in their shape or the compounds they secrete. This diversity is expressed between species but also within species or even individual plants. The industrial uses of some trichome secretions and their potential as a defense barrier, for example against arthropod pests, has spurred research into t...
متن کاملComparative functional genomic analysis of Solanum glandular trichome types.
Glandular trichomes play important roles in protecting plants from biotic attack by producing defensive compounds. We investigated the metabolic profiles and transcriptomes to characterize the differences between different glandular trichome types in several domesticated and wild Solanum species: Solanum lycopersicum (glandular trichome types 1, 6, and 7), Solanum habrochaites (types 1, 4, and ...
