— The male program of ontogeny in flowering plants encompasses the events from meiosis of microsporocytes to fertilization. Three main sequences are discussed; the deposition of cell walls, changes in cytoplasmic organelles, and the program of nucl

Cytochemical methods have been used in conjunction with light and electron microscopy to determine the nature of the inclusions in aleurone grains of barley aleurone layers. Two kinds of inclusions were found: (1) Globoids within globoid cavities whi

The position of the callose wall is related to the position of the primexine matrix that forms around the peripheral tetrads during microspore development of the compound unit, the pollinium. We report a combined freeze-fracture and freeze-substituti

In Pterostylis concinna individual pollen grains all possess an outer exine wall, pollinia are mealy, and they fall apart easily. In contrast, Dendrobium spp. have hard pollinia in which only pollen grains on the outer surface have an exine, inner po

Grass pollen allergens are known to be present in the atmosphere in a range of particle sizes from whole pollen grains (approx. 20 to 55 microns in diameter) to smaller size fractions2.5 microns (fine particles, PM25). These latter particles are with

We have studied the expression of recombinant forms of Group 1 allergens from rye-grass and Bermuda grass pollens. Recombinant Lol p 1 expressed in bacteria bound serum IgE from allergic patients. Based on analysis of fragments of the Lol p 1 cDNA cl

Three distinct secretory events in tapetal cells correspond to key processes of microspore development: microspore release and expansion, exine development, and pollen-coat formation and dispersal. First, at the tetrad stage, the lower part of the ra
