Abstract
For centuries, crop plants have represented the basis of the daily human diet. Among them, cereals and legumes, accumulating oils, proteins, and carbohydrates in their seeds, distinctly dominate modern agriculture, thus play an essential role in food industry and fuel production. Therefore, seeds of crop plants are intensively studied by food chemists, biologists, biochemists, and nutritional physiologists. Accordingly, seed development and germination as well as age- and stress-related alterations in seed vigor, longevity, nutritional value, and safety can be addressed by a broad panel of analytical, biochemical, and physiological methods. Currently, functional genomics is one of the most powerful tools, giving direct access to characteristic metabolic changes accompanying plant development, senescence, and response to biotic or abiotic stress. Among individual post-genomic methodological platforms, proteomics represents one of the most effective ones, giving access to cellular metabolism at the level of proteins. During the recent decades, multiple methodological advances were introduced in different branches of life science, although only some of them were established in seed proteomics so far. Therefore, here we discuss main methodological approaches already employed in seed proteomics, as well as those still waiting for implementation in this field of plant research, with a special emphasis on sample preparation, data acquisition, processing, and post-processing. Thereby, the overall goal of this review is to bring new methodologies emerging in different areas of proteomics research (clinical, food, ecological, microbial, and plant proteomics) to the broad society of seed biologists.

Abstract
Many plant genes have been cloned that encode regioselective desaturases catalyzing the formation of cis-unsaturated fatty acids. However, very few genes have been cloned that encode enzymes catalyzing the formation of the functional groups found in unusual fatty acids (e.g. hydroxy, epoxy or acetylenic fatty acids). Here, we describe the characterization of an acetylenase from the moss Ceratodon purpureus with a regioselectivity differing from the previously described Delta12-acetylenase. The gene encoding this protein, together with a Delta6-desaturase, was cloned by a PCR-based approach with primers derived from conserved regions in Delta5-, Delta6-fatty-acid desaturases and Delta8-sphingolipid desaturases. The proteins that are encoded by the two cloned cDNAs are likely to consist of a N-terminal extension of unknown function, a cytochrome b5-domain, and a C-terminal domain that is similar to acyl lipid desaturases with characteristic histidine boxes. The proteins were highly homologous in sequence to the Delta6-desaturase from the moss Physcomitrella patens. When these two cDNAs were expressed in Saccharomyces cerevisiae, both transgenic yeast cultures desaturated Delta9-unsaturated C16- and C18-fatty acids by inserting an additional Delta6cis-double bond. One of these transgenic yeast clones was also able to introduce a Delta6-triple bond into gamma-linolenic and stearidonic acid. This resulted in the formation of 9,12,15-(Z,Z,Z)-octadecatrien-6-ynoic acid, the main fatty acid found in C. pupureus. These results demonstrate that the Delta6-acetylenase from C. pupureus is a bifunctional enzyme, which can introduce a Delta6cis-double bond into 9,12,(15)-C18-polyenoic acids as well as converting a Delta6cis-double bond to a Delta6-triple bond.

Abstract
The lipid content and fatty acid profiles of four lesser known tropical seeds, Piper guineense, Chrysophyllum albidum, Garcinia kola and Dennettia tripetala, were determined. The total lipid content (g/kg dry weight) ranged between 31.8 and 68.9. The ranges of values for neutral lipids, triacylglycerol of neutral lipids, glycolipids and phospholipids were 17.3-58.0, 15.0-49.6, 3.0-7.2 and 3.7-11.2, respectively. The fatty acid profiles showed variation among different seeds. All the seeds contained substantial amounts of unsaturated fatty acids. Oleic and linoleic acids were the most abundant fatty acids. Dennettia tripetala and Piper guineense also contained moderate amounts of linolenic acid.

Abstract
Data on tooth use in eating fruits and seeds were collected on 12 West African monkeys representing five species of cercopithecines, Cercopithecus aethiops, Cercopithecus campbelli, Cercocebus atys, Erythrocebus patas, and Papio papio. Field observations and information in the published literature were used to select fruits for captive feeding trials. A total of over 27,000 tests were conducted to determine the preferences of the monkeys for 78 fruits. Data were collected on the selection of fruit parts, as well as tooth use, in eating 88 fruit species. All five monkey species had remarkably similar fruit part preferences. Seeds were eaten in 86% of the tested fruits and represent the fruit part most frequently eaten by all the tested monkeys. With few exceptions, molars were used to puncture and crush the seeds. It is suggested that the development of bilophodont molars might be an adaptation by Old World monkeys to seed predation. Given their large size relative to other arboreal frugivores, seed predation could provide a dietary niche for Old World monkeys.

Abstract
Two structurally distinct lipid vesicles are present in pea and bean cotyledons during the first few days of germination. Both were isolated by sucrose density gradient centrifugation without significant morphological changes. Lipid vesicles of one type were elongated into a sausage-like or flattened-saccular shape, and were interassociated into sheets which were usually one vesicle thick. These sheets remained intact during homogenization and centrifugation, because some of the lipid vesicles in the sheet were interconnected through their bounding membranes, and because there seemed to be a bonding substance between adjacent vesicles. These vesicles were called "composite" lipid vesicles to distinguish them from the more usual, or "simple," lipid vesicles of other plant and animal tissues. Lipid vesicles of the other type were usually larger than the composite lipid vesicles and were always spherical in form. These vesicles remained single and did not interassociate into sheets. They were probably equivalent to the simple lipid vesicles of other tissues.

Abstract
Coriolic [(R)-13-hydroxy-cis-9,trans-11-octadecadienoic] acid (III, R=Z=H) was isolated as the methyl ester from twoCoriaria seed oils in 66 and 68% yields. The double bonds and hydroxyl group were located by periodate-permanganate oxidation before, and chromic acid oxidation after, hydrogenation of the double bonds. Alternatively the positions of the functional groups were indicated by a convenient micro-ozonolysis-gas-liquid chromatographic procedure. Determination of products from partial hydrolysis of theCoriaria oils with pancreatic lipase (EC 3.1.1.3) revealed a preference of the corioloyl group for the 1,3-positions in triglyceride molecules. The possible significance of coriolic acid as an intermediate in the biogenetic conversion of linoleic acid to conjugated trienoic acids is discussed.

Abstract
Preliminary studies show that red stem, rust-infected wheat plants provide a means for investigating the biosynthesis of epoxy fatty acids. The incorporation of 1-(14)C-acetate intocis-9,10-epoxyoctadecanoic acid occurs at the stage of the infection when sporulation is proceeding, and at the same stage there is at least a fourfold increase in the synthesis of other fatty acids. The epoxy acid appears to be formed by the condensation of acetate units in a process that requires oxygen and is not stimulated appreciably by light.Labeled stearic and oleic acid are also incorporated into the epoxy acid without undergoing beta-oxidation. The rate of conversion of oleic acid is greater than stearic acid, thus indicating that oleic acid is an immediate precursor to 9,10-epoxyoctadecanoic acid.

Abstract
Two different series of experiments were performed to establish the origin of the oxygen molecule incorporated into hydroperoxide during the incubation of lipoxidase with linoleic acid. These showed, as previously assumed but never demonstrated, that the oxygen introduced into the hydroperoxide molecules comes from the gaseous phase and not from the aqueous phase. Furthermore, soybean lipoxidase does not catalyze the exchange between gaseous oxygen and water oxygen. Possibly, lipoxidase may be involved in the biosynthesis of hydroxytrans,cis conjugated octadecadienoates present in various seeds.
