Thigmo Responses: The Fungal Sense of Touch - PubMed
Contact sensing, or thigmo-based responses, include thigmo differentiation, such as the induction of invasion structures by plant pathogens in response to topography; thigmonasty, where contact with a motile prey rapidly triggers its capture; and thigmotropism, where the direction of hyphal growth is guided by physical features in the environment.

2002年3月1日 · Changes in both growth rates and morphological differentiation, due to thigmomorphogenesis, are illustrated by thigmo responses of numerous fungi. The ridge pattern on the surface of a leaf can induce a directional orientation of mycelial growth (thigmotropism) (Johnson, 1934; Hoch et al., 1987). In another example, in certain species of the ...
Thigmo mechanisms are adaptations that permit a plant to alter growth rates, change morphology, produce tropisms, avoid barriers, control germination, cling to supporting structures, infect a host plant, facilitate pollination, expedite the movement of pollen, spores, or seeds, and capture prey.

2017年4月14日 · Contact sensing, or thigmo-based responses, include thigmo differentiation, such as the induction of invasion structures by plant pathogens in response to topography; thigmonasty, where contact with a motile prey rapidly triggers its capture; and thigmotropism, where the direction of hyphal growth is guided by physical features in the environment.
Induction of contour sensing in Aspergillus niger by stress and its ...
2007年6月1日 · We propose that growth under nutrient-limited conditions triggers several factors that combine to increase thigmotropic sensitivity while conversely creating a 60° arc at the hyphal tip which is blind to topographical variations.
Tropic Orientation Responses of Pathogenic Fungi
2011年10月17日 · In this chapter, we review the tropic, or pre-programmed, growth responses of fungal pathogens which are involved in disease progression in plants and humans. Thigmotropism is the movement or orientation of an organism or cell in relation to the topography, shape and physical properties of the underlying substrate on which it is growing.

fungal growth and growth control will provide valuable in-formation on both hyphal structure and development. We have created a system to examine the complex thigmotropic reactions of the ubiquitous fungus Aspergillus niger using a combination of microscopy and microengineering. We have investigated the effect of nutritional stress on topographical
Regulation of vectorial supply of vesicles to the hyphal tip …
2014年3月1日 · Filamentous fungi grow by polarized extension of tubular hyphae which rely on signals from their environment to adapt growth. Thigmotropism is a growth response to a mechanical stimulus and has been observed in many species of fungi such as Candida albicans (Perera et al., 1997, Brand et al., 2007), Aspergillus niger (Fischer et al. 2008 ...
