Antique Framed Print : False-colour SEM of cocksfoot grass
Framed Photos from Science Photo Library
False-colour SEM of cocksfoot grass
False-colour scanning electron micrograph (SEM) of two pollen grains of cocksfoot grass, Dactylis glomerata, a major cause of hay fever (allergic rhinitis). 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. Hay fever 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: x570 at 6x4.5cm size.

EDITORS COMMENTS
This print showcases a false-colour scanning electron micrograph (SEM) of two pollen grains from cocksfoot grass, scientifically known as Dactylis glomerata. These tiny grains are responsible for triggering hay fever, also known as allergic rhinitis. The image reveals intricate details of the pollen grains, with the right-hand grain featuring a visible pit called the germination pore. This is where the pollen tube emerges and grows. Cocksfoot grass produces wind-dispersed summer pollen, which can be highly problematic for individuals suffering from hay fever. Those affected by this condition produce an antibody called immunoglobin E (IgE), which attaches to cells in their nose and eyes. When inhaled pollen comes into contact with these sensitized cells, it triggers the release of various chemicals including histamine. Histamine then causes inflammation and swelling of the mucous membranes in the nose, eyes, and throat - leading to those familiar symptoms associated with hay fever. This SEM image offers us a closer look at the culprit behind so much seasonal discomfort. With a magnification level of x570 at 6x4.5cm size, this photograph was taken from MICROCOSMOS's collection on page 82 under figure 4.32 using blue and yellow JBU colouring techniques provided by Science Photo Library - experts in capturing stunning images that bridge science and artistry.
