Many of what scientists know about trichome development comes from the model organism Arabidopsis thaliana, because their trichomes are simple, unicellular, and non-glandular.

Jul 29, 2025 · In agriculture, understanding trichome development and function is used to improve crop pest resistance. Plants with higher densities of trichomes or those producing specific deterrent …

A trichome is initiated as a protuberance from an epidermal cell. The protuberance elongates, and if it develops into a multicellular structure various divisions may follow the initial elongation.

Other articles where trichome is discussed: fern: Surface structure: …consisting of hairs, known as trichomes, or scales; these are so distinctive that they are valuable in identification and classification.

Jul 20, 2025 · The term “trichome” derives from the Greek word “trichos,” meaning hair. These “hairs” may appear as simple unicellular projections or complex multicellular glandular structures that …

Environmental and endogenous signals closely regulate trichome development. Several plant hormones, including those mentioned above (GA and CTK) are involved in trichome differentiation in …

Apr 22, 2019 · What regulates the shape of trichome cells? Trichome shape regulation relies on two processes — the initiation of branch points and extension growth. Extension growth requires the …

Jan 1, 2024 · Phytohormones are essential for initiating and developing trichomes. The unicellular and multicellular/glandular trichomes development exhibits distinct regulatory mechanisms. Trichome …

Recent advances have revealed that trichome initiation, patterning and subsequent differentiation are regulated by complex molecular networks.

The structure, shape, position and even thickness of a trichome is a response to their environment. They serve as examples of how evolutionary adaptation allows plants to survive their environment.
