Abstract:
Phytohemagglutinin (Difco) stimulates germination and early seedling growth in Phaseolus coccineus, but not in Ph. vulgaris, the species from which the compound is extracted. The differences to the controls reach a maximum at day 8, then they disappear. Root growth in Allium cepa is enhanced by phytohemagglutinin during the first 12 days of treatment, but only at temperatures below 20°C.

24.6K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

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.

Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...
