Pollen grains of Cocksfoot grass
False-colour scanning electron micrograph (SEM) of two pollen grains of cocksfoot grass, Dactylis glomerata. The pit on the right-hand grain is the germination pore, out which the pollen tube grows. Cocksfoot pollen is a wind- dispersed summer pollen & a major cause of hay fever (Allergic rhinitis or pollenosis). Sufferers produce a sensitising antibody, immunoglobin E (IgE), which attaches to cells in the nose & eyes. It reacts with inhaled pollen, causing the release of various chemicals including histamine. Histamine causes the mucous membranes of the nose, eyes & throat to swell & become inflamed, bringing on the symptoms of hay fever. Magnification: x370 at 35mm size. Gold tint. Original is bw print B786/073 Ref: MICROCOSMOS, fig. 4.32, p. 82

EDITORS COMMENTS
This print showcases the intricate beauty of pollen grains from Cocksfoot grass, scientifically known as Dactylis glomerata. Through a false-color scanning electron micrograph (SEM), two pollen grains are depicted in stunning detail. The grain on the right exhibits a germination pore, which serves as an exit point for the emerging pollen tube. Cocksfoot grass is notorious for its wind-dispersed summer pollen, making it a significant contributor to hay fever or allergic rhinitis. Individuals suffering from this condition produce immunoglobin E (IgE), a sensitizing antibody that attaches to cells in the nose and eyes. Upon inhalation of cock's foot pollen, IgE triggers the release of various chemicals including histamine. Histamine plays a pivotal role in causing inflammation and swelling of mucous membranes in the nose, eyes, and throat – hallmark symptoms of hay fever. This microscopic image offers insight into how such tiny particles can have such profound effects on human health. Magnified at 370 times its original size with a gold tint added for visual appeal, this photograph provides an opportunity to appreciate nature's intricacies while shedding light on an important aspect of plant reproduction and human allergies. It is part of Science Photo Library's collection titled "MICROCOSMOS" and can be found on page 82 under figure 4.32.
