Plant glandular trichomes (GTs) are crucial for specialized metabolites. This review details GT development, metabolite pathways, and technological advances, aiding plant breeding and epidermal research.
Area of Science:
- Plant biology
- Molecular genetics
- Biochemistry
Background:
- Plant glandular trichomes (GTs) are epidermal outgrowths vital for producing specialized metabolites.
- Current understanding of GT development is limited, lacking a universal model species.
- GTs are significant in horticulture for desirable metabolite production.
Purpose of the Study:
- To review the genetic mechanisms of GT initiation and development.
- To summarize specialized metabolite biosynthetic pathways in nonmodel plants, particularly horticultural crops.
- To highlight technological advancements in GT research.
Main Methods:
- Literature review of genetic mechanisms.
- Compilation of biosynthetic pathways for specialized metabolites.
- Discussion of GT morphology, classification, and investigation technologies.
Main Results:
- Detailed overview of genetic factors controlling GT development.
- Summary of diverse specialized metabolite production in various plant species.
- Identification of key technologies for studying GTs.
Conclusions:
- Understanding GT molecular development and metabolite synthesis is key for plant breeding.
- This knowledge can improve the production of valuable compounds.
- Insights gained will advance research in plant epidermal development.
