Summary
Arborists can develop a rash from Ficus carica exposure. This phytophotodermatitis causes blistering eruptions on skin after contact with the fig tree.
Area of Science:
- Dermatology
- Botany
Background:
- Phytophotodermatitis is a skin reaction caused by plant sap and sun exposure.
- Ficus carica, commonly known as the fig tree, contains photosensitizing compounds.
Observation:
- Two arborists experienced acute blistering eruptions on their forearms, hands, and fingers after pruning a damaged Ficus carica tree.
- Symptoms included burning discomfort, erythema, and bullae on sun-exposed skin areas.
Findings:
- The symptoms developed the morning after exposure and resolved over 4 to 6 weeks.
- The reaction is consistent with phytophotodermatitis, a known but often underrecognized condition associated with Ficus species.
Implications:
- Increased awareness of Ficus carica-induced phytophotodermatitis is crucial for arborists, orchardists, and gardeners.
- Prompt recognition and management can prevent misdiagnosis and ensure appropriate patient care.

02:26Defenses Against Pathogens and Herbivores
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

02:00Photoreceptors and Plant Responses to Light
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.
02:40Epiphytes, Parasites, and Carnivores
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the biosynthesis of the...

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
