Secreting glandular trichomes: more than just hairs.
Secreting glandular plant trichome types which accumulate large quantities of metabolic products in the space between their gland cell walls and cuticle permit the plant to amass secretions in a compartment that is virtually outside the plant body. These structures not only accumulate and store what are often phytotoxic oils but they position these compounds as an apparent first line of defense...
متن کاملUltrastructure of organic acid secreting trichomes of chickpea (Cicer arietinum)
LAZZARO, M. D., and THOMSON, W. W. 1989. Ultrastructure of organic acid secreting trichomes of chickpea (Cicer arietinum). Can. J. Bot. 67: 2669-2677. The acid-secreting trichomes of chickpea (Cicer arietinum L.) were composed of 18 cells, including 1 basal cell, 3 elongate stalk cells, and 14 head cells. A subcuticular secretion chamber with cuticular pores was present above the head cells at ...
متن کاملUltrastructural localization of calcium in the organic acid secreting trichomes of chickpea (Cicer arietinum)
LAZZARO, M. D., and THOMSON, W. M. 1992. Ultrastructural localization of calcium in the organic acid secreting trichomes of chickpea (Cicer arietinurn). Can. J . Bot. 70: 2319-2325. In the organic acid secreting trichomes of chickpea (Cicer arietinutn L.), calcium is localized in the stalk and head cells using pyroantimonate and X-ray microanalysis. Light calcium deposits are present in the end...
متن کاملBRANCHLESS TRICHOMES links cell shape and cell cycle control in Arabidopsis trichomes.
Endoreplication, also called endoreduplication, is a modified cell cycle in which DNA is repeatedly replicated without subsequent cell division. Endoreplication is often associated with increased cell size and specialized cell shapes, but the mechanism coordinating DNA content with shape and size remains obscure. Here we identify the product of the BRANCHLESS TRICHOMES (BLT) gene, a protein of ...
متن کاملDevelopment of peltate glandular trichomes of peppermint.
Cryofixation and conventional chemical fixation methods were employed to examine the ultrastructure of developing peltate glandular trichomes of peppermint (Mentha x piperita). Our results are discussed in relation to monoterpene production and the mechanism of essential oil secretion. Peltate glands arise as epidermal protuberances (initials) that divide asymmetrically to produce a vacuolate b...
