“…Relative detection frequencies of tentatively identified phospholipids and of glycoand sulfolipids correspond with those reported in other studies (Stanley and Linskens, 1974;Katsumata et al, 1975;Opute, 1975Opute, , 1978Larianova et al, 1977;Delbart, Bris, and Coustaut, 1983). As might be expected, triglycerides, which are important reservoirs of metabolic energy in pollen (Scott and Strohl, 1962;Stanley and Linskens, 1974), represented a larger proportion ofthe total neutral lipids in the internal fractions than in pollenkitt.…”

A chemical survey of pollen lipids was carried out to examine the composition of pollenkitt in relation to that of whole pollen and to evaluate the possible role of pollenkitt as the principal carrier of chemical cues used by flower visitors. Investigated pollen was collected from 69 angiosperm species (28 families) in California. Lipid extracts of pollenkitt and of the internal portion of pollen were analyzed for each species using thin‐layer chromatography. Neutral lipids (energy storage and essential oil constituents) were most diverse in pollenkitt, while polar lipids (mostly membrane constituents) were found almost exclusively in the internal pollen fraction. Patterns in neutral lipid compositions suggest that pollenkitt may provide pollen with species‐specific odors. Yellow pigments were observed in pollen of most species, with carotenoids predominating in pollenkitt and flavonoids in the internal fraction. Phenolic and heterocyclic nitrogen compounds were found in the lipid extracts of several species.

“…If the pollens are milled so as to fracture the pollen walls, the lipid concentrations can increase. In Brassica napus it can increase from 9.8% to 21.9% 8 and 9.3% to 25.4% 9 and, in Pinus taeda from 1.5% to 6.1% 31 . Of interest is that there are differences in fatty acid composition between the pollen coat and internal areas of the pollen grains.…”

“…These solvents will extract a variable proportion of the intracellular pollen lipids in addition to those of the pollen coat. It is therefore not surprising that such extracts tend to be relatively enriched in triacylglycerols, which are almost certainly derived from the intracellular domain of the pollen grains (Scott and Strohl 1962;Caffrey et al 1987;Bianchi et al 1990; Thompson et al 1993). Apart from triacylglycerols, the major pollen lipids reported in many of these studies are non-polar esters such as triterpene esters (Bianchi et al 1990) and sterol esters (Caffrey et al 1987).…”

“…Analysis of pollen lipid fractions has also shown the presence of relatively small, but significant, amounts of very long-chain wax esters (Scott and Strohl 1962;Bianchi et al 1990;Preuss et al 1993), the lack of which can adversely affect pollen grain fertility (Preuss et al 1993;Lemieux 1996;Negruk et al 1996). For example, the conditional partial or complete male-sterile eceriferum (cer) class of Arabidopsis mutants lacks all or part of the pollen coat structure as a result of lesions in very longchain acyl lipid synthesis pathways (Preuss et al 1993;Aarts et al 1995).…”

Pollen grains contain several lipidic structures, which play a key role in their development as male gametophytes. The elaborate extracellular pollen wall, the exine, is largely formed from acyl lipid and phenylpropanoid precursors, which together form the exceptionally stable biopolymer sporopollenin. An additional extracellular lipidic matrix, the pollen coat, which is particularly prominent in entomophilous plants, covers the interstices of the exine and has many important functions in pollen dispersal and pollen-stigma recognition. The sporopollenin and pollen coat precursors are both synthesised in the tapetum under the control of the sporophytic genome, but at different stages of development. Pollen grains also contain two major intracellular lipidic structures, namely storage oil bodies and an extensive membrane network. These intracellular lipids are synthesised in the vegetative cell of the pollen grain under the control of the gametophytic genome. Over the past few years there has been significant progress in elucidating the composition, biogenesis and function of these important pollen structures. The purpose of this review is to describe these recent advances within the historical context of research into pollen development.& k w d : Key words Lipid · Pollen · Tapetum · Microspore · Sporopollenin · Oil body& b d y :
