Pollen is made up of many chemical constituents such as proteins, sugars, lipids, minerals and phytochemicals. These components make pollen products an excellent source of nutrients and antioxidants for consumers. However, mycotoxigenic fungi are also common in pollen, creating contamination from generated mycotoxins. With adequate monitoring, sampling, processing and storage of pollen the development of mycotoxins can be significantly prevented. Since pollen grain has strong membranes which can limit the bioavailability of some nutrients and phytochemicals, novel methods and pretreatments are required with special emphasis on microbiological pretreatment methodologies. Pollen Chemistry & Biotechnology summarizes current knowledge of the chemical composition of pollen, its importance as a functional food ingredient and its health promoting properties. As Introduction part a short elaborate about botanical characteristics and data, including morphology and anatomy of pollen and bee preferences, is given. Important factors such as the botanical and geographical origin, best practices for preservation of nutritional composition, bioactivity and safety of pollen are covered in full. The nutritional profile of pollen based on data for minerals, lipids and nutrients is presented. A detailed phytochemical profile of pollen based on data for phenolics, flavonoids, carotenoids, vitamins, bioactive compounds is also covered. Areas for the improvement of the bioavailability of different nutrients and bioactive compounds of pollen via applied pretreatments are presented, as are best practices for adequate pollen collection, procession and storage in order to obtain safe products. At the end, an overview about pollen bioactivity as reason to use it as source of pharmaceuticals is made.

This volume explores a collection of experimental techniques used to investigate different aspects of pollen development and function, including its role in reaching the ovule and delivering the two sperm cells. The techniques discussed range from basic methodology to cultivate pollen in vitro to the sophisticated experiments involving micromanipulation, Lab-on-Chip technology, or high-end imaging. The chapters in this book cover topics such as pollen grain counting using a cell counter; restricted pollination for tracing individual pollen tubes in a pistil; obtaining mutant pollen for phenotypic analysis and pollen tube dual-staining; analyzing intracellular gradients in pollen tubes; and measuring exocytosis rate in Arabidopsis pollen tube using corrected fluorescence recovery after photoconversion (cFRAPc) technique. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, Pollen and Pollen Tube Biology: Methods and Protocols is a valuable resource for novice and expert scientists interested in learning more about the field of plant reproduction.

Secondary pollen presentation is presentation of pollen to vectors by structures other than anthers, either passively or via a specialized protection and delivery system. The main part of the book describes secondary pollen presentation genus-by-genus in 25 families. The subject has never been extensively reviewed, although secondary pollen presentation occurs in the largest family of flowering plants, the Asteraceae (Compositae), and a large family of great economic importance, the Leguminosae. Now material from the scattered literature is brought together and supplemented with original observations. Many species are illustrated and each family is individually discussed. The last two chapters provide an overview of the whole topic. All the main functions that secondary pollen presentation may perform can be carried out in other plants without it. It is concluded from this that the evolution of secondary pollen presentation has been subject to constraint and canalization. The floral biology of most plants with secondary pollen presentation has not been adequately studied. Appendix 1 points to a wide range of topics on which research at various technical and academic levels is needed. The book should also become a reference work for morphologists, systematists, and floral ecologists.

AN INTRODUCTION TO POLLEN ANALYSIS by G. ERDTMAN. FOREWORD: It has long been the custom among those making pollen surveys to expose microscope slides coated with a suitable adhesive and examine them for the pollen grains caught. The counts of the various species are tabulated each day and at the end of the season drawn into a graph or pollen spectrum, as it is called , which gives a clear picture of the relative amounts of the different kinds of pollen which are floating in the air from day to day throughout the growing season If done in the north temperate zone such a spectrum will show the pollen of the early flowering trees, at first a trickle, as the junipers, alders and hazels flower, then a deluge as the birches, oaks and pines ami many other trees cast their pollen to the air. This is generally followed by a long stream of grass pollen, fluctuating from week to week as the various species come into flower, reach their zenith, then die out giving way to succeeding species And toward the end of the summer pollens of the late flowering weeds make their appearance, nowadays in most places com pletely dominated by that of the ragweed. If the record is repeated the following year the spectrum will be nearly the same The succession can be counted on to repeat itself with hltle change from year to year for many years to come, unless some cataclysm changes the surrounding vegetation which contributes to the pollen spectrum, for it is always a faithful representation of the surrounding vegetation...
