Distribution of Peltate Glandular Trichomes on Developing Leaves of Peppermint [PDF]

open access: yesPlant Physiology, 2000
The pattern of peltate glandular trichome initiation and ontogeny on expanding peppermint (Mentha x piperita) leaves was defined by surveying the populations of peltate glands in each of seven developmental stages within sampling areas of leaf apical, mid-, and basal zones for both abaxial and adaxial surfaces.

Advances in the regulatory mechanisms of multicellular trichome formation and its secondary metabolite synthesis in vegetable crops

open access: yesVegetable Research, 2023
Trichomes are specialized epidermal appendages, which can be divided into glandular or non-glandular types based on their diverse morphology. The glands of glandular trichomes are responsible for the biosynthesis and storage of many natural metabolites ...

Developmental Regulation of Monoterpene Biosynthesis in the Glandular Trichomes of Peppermint [PDF]

open access: yesPlant Physiology, 2000
Abstract Monoterpene production in peppermint (Mentha ×piperita L.) glandular trichomes is determined by the rate of biosynthesis, as determined by 14CO2incorporation, and is restricted to leaves 12 to 20 d of age. Using oil glands isolated from peppermint leaves of different ages, in vitro assay of the eight sequential enzymes ...

Mazus dabieshanensis sp. nov. (Mazaceae) from eastern China

open access: yesNordic Journal of Botany, EarlyView.
Mazus dabieshanensis, a newly described species endemic to the Dabieshan Mountains in eastern China, is illustrated and described. Molecular phylogenetic analyses based on nuclear and chloroplast DNA sequences consistently demonstrate that this new species forms a stable clade with other Mazus species characterized by a pubescent ovary. Morphologically,
