Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress.

Trichomes are multifunctional epidermal hair structures that integrate structural, physiological, and metabolic roles to defend plants and adapt to environmental stresses, including drought and heavy metals.

• Why it matters: The work addresses how plants coordinate trichome development and function across defence, adaptation, and secondary metabolite production under environmental adversity.
• What they did: It reviews trichome developmental biology, emphasizing transcriptional hierarchies, hormonal crosstalk, epigenetic remodelling, and post-transcriptional modulation, and distinguishes glandular versus non-glandular types.
• The result: It links glandular trichomes to biosynthesis of terpenoids, alkaloids, and phenolics, and outlines emerging approaches like single-cell omics and metabolic/genetic engineering for crop improvement and sustainable metabolic engineering.
